What is the value of x when solving the equation 4x+(-4) = -2x+8

1. Growth came from personal and government spends and other investments.

2. Economy is slowing down and reflects weaker outlook in 2020

1.  Real Gross Domestic Product showed increment at the rate of 1.9% annually by the end of 3rd quarter of 2019. This estimate was released by Bureau of economic analysis. They also had estimated that Real GDP was increased by approximately 2.0% when 2nd quarter of 2019 ended.

Factors that contributed the increase in real GDP by the end of 3rd quarter included expenditures and consumption of the common people for personal use, expenditure of federal government along with local and state governments, investments in fixed residential assets, and also exports.

2. International Monetary Fund estimated and projected a slower growth rate for United States in 2019 and 2020 and revised the growth rate as downward of 0.3% for both 2019 and 2020.  This shows us that GDP will now grow at the rate of 7% and 7.2% , which reflects a very weak outlook for domestic demand, weaker than expected. Global trade tension poses a threat to the economic outlook.

Answer: The function is EVEN.

Step-by-step explanation:

For this exercise it is important to remember that:

1. A function f(x) is even if and only if:

[tex]f(-x) = f(x)[/tex] for all "x"

2. A function f(x) is odd if and only if:

[tex]f(-x) = -f(x)[/tex] for all "x"

So knowing that, and given the following function k(x):

[tex]k(x)=x^6 - x^2 + 7[/tex]

You can plug [tex]-x[/tex] in for "x", order to know if this is even. Then, you get:

[tex]k(-x)=(-x)^6 - (-x)^2 + 7\\\\k(-x)=x^6-x^2+7[/tex]

Therefore, since:

[tex]f(-x) = f(x)[/tex]

You can determine that that the given function [tex]k(x)=x^6 - x^2 + 7[/tex] is Even.

Number of students in senior class is 130

Solution:

Given that Every student in the senior class is taking history or science

85 of them taking both history and science

106 seniors takes history

109 seniors takes science

To find: number of students in senior class

Let A be the set of the students of the senior class that take history

Let B be the set of students of senior class that they science

The number of students in senior class is given by:

[tex]|A \cup B|=|A|+|B|-|A \cap B|[/tex]

Where,

A = 106 and B = 109 and |A n B| = 85

[tex]|A \cup B|=106+109-85=130[/tex]

Thus number of students in senior class is 130

Answer:

130

Step-by-step explanation:

Since 106 seniors are taking history and 109 seniors are taking science. If we add those numbers of seniors up we get 215, then we subtract the number of seniors that are taking both history and science because we counted them twice. So the total is 215 - 85 = 130. Therefore there are 130 students in the senior class.

Mrs. clark spends $89.85 on science kits that cost $5 each plus $4.85 tax on the total bill. How many kits did she buy?

Mrs. Clark bought 17 science kits

Given that Mrs. clark spends $89.85 on science kits that cost $5 each plus $4.85 tax on the total bill

To find: number of kits she bought

Cost of one kit = $ 5

Tax amount = $ 4.85

Total amount spend including tax = $ 89.85

Lets first get rid of the tax in the total amount

Amount without tax = Total amount spend including tax - Tax amount

Thus amount without tax = $ 89.85 - $ 4.85 = $ 85

Since we know that each kit costs $5,  we would divide 85 by 5 to see find how many kits she bought

[tex]\begin{array}{l}{\text { number of kits bought }=\frac{\text { amount spent }}{\text { cost of one kit }}} \\\\ {\text { number of kits bought }=\frac{85}{5}=17}\end{array}[/tex]

Thus Mrs. clark has bought 17 science kits

Answer:

Step-by-step explanation:

line G :

5y = -2x - 20...put in slope intercept form (y = mx + b)

y = -2/5x - 4....the slope(m) = -2/5

Part A.) slope intercept form for line R...since R is parallel to G, it will have the same slope....so slope(m) = -2/5

(-10,8)...x = -10 and y = 8

slope(m) = -2/5

y = mx + b

8 = -2/5(-10) + b

8 = 4 + b

8 - 4 = b

4 = b

so ur equation is : y = -2/5x + 4 <=== part A answer

since line E is perpendicular to line G, it will have a negative reciprocal slope...all that means is flip the slope and change the sign....so the slope of line E is : (flip -2/5.....-5/2.....change the sign......5/2)

(-10,8)...x = -10 and y = 8

slope(m) = 5/2

y = mx + b

8 = 5/2(-10) + b

8 = -25 + b

8 + 25 = b

33 = b

so ur equation is : y = 5/2x + 33 <== part B answer

The equation for line R is y = -2/5x + 12. The equation for line E is y = 5/2x + 33.

Part A: To write the equation for line R in slope-intercept form, we need to find the slope and the y-intercept. Since line R is parallel to line G, it will have the same slope. The slope of line G can be determined by dividing the coefficient of x by the coefficient of y: -2/5. We can use the point-slope form, y - y1 = m(x - x1), to find the equation. Substituting the coordinates of the point (-10,8), the equation for line R is y - 8 = (-2/5)(x + 10). Simplifying, we get the equation for line R: y = -2/5x + 12.

Part B: To write the equation for line E in slope-intercept form, we need to find the slope and the y-intercept. Since line E is perpendicular to line G, its slope will be the negative reciprocal of the slope of line G. The slope of line G is -2/5, so the slope of line E will be 5/2. Using the point-slope form and substituting the coordinates of the point (-10,8), the equation for line E is y - 8 = (5/2)(x + 10). Simplifying, we get the equation for line E: y = 5/2x + 33.

The quantity "q" sold by Catera is 13

Solution:

Given that Catera has found that as she increases her price, p, the quantity she sells q, decreases

The following equation relates q, the quantity she sells, to p, the price she charges:

Where, "p" is the price and "q" is the quantity she sells

Given that Catera price is $ 232

To find: quantity she sells

Substitute p = 232 in given equation

232 = 284 - 4q

4q = 284 - 232

4q = 52

[tex]q = \frac{52}{4} = 13[/tex]

Answer:

-2.5

Step-by-step explanation:

We are given that a quadratic  function  graph f(x).

We have to find the value of f(6).

The given graph is parabolic .

The vertex of the graph is at (3,-2).

The graph cut the x -axis at point (1,0) and (5,0).

The graph cut the y-axis at point (0,-2.5).

To find the value of f(6) we will find the value of y  corresponding to x=6.

When we draw a vertical line x=6 then we see that it cuts the given graph at point (6,-2.5).

Therefore, the value of f(6)=-2.5

Hence, the f(6) for the quadratic function graph=-2.5

Step-by-step explanation:

step 1

Find the measure of angle AOC

The triangle AOC is an isosceles triangle, because OA=OC=radius

so

[tex]m\angle OAC=m\angle OCA=28^o[/tex]

Remember that the sum of the interior angles in any triangle must be equal to 180 degrees

[tex]m\angle OAC+m\angle OCA+m\angle AOC=180^o[/tex]

substitute the given values

[tex]28^o+28^o+m\angle AOC=180^o[/tex]

[tex]56^o+m\angle AOC=180^o[/tex]

[tex]m\angle AOC=180^o-56^o[/tex]

[tex]m\angle AOC=124^o[/tex]

step 2

Find the measure of arc AC

we know that

[tex]arc\ AC=m\angle AOC[/tex] ----> by central angle

we have

[tex]m\angle AOC=124^o[/tex]

therefore

[tex]arc\ AC=124^o[/tex]

step 3

we know that

The inscribed angle is half that of the arc comprising

[tex]m\angle ABC=\frac{1}{2}[arc\ AC][/tex]

[tex]m\angle ADC=\frac{1}{2}[arc\ AC][/tex]

so

[tex]m\angle ABC=m\angle ADC[/tex]

therefore

[tex]m\angle ABC+m\angle ADC=2m\angle ABC=arc\ AC[/tex]

substitute the value of the arc AC

[tex]m\angle ABC+m\angle ADC=124^o[/tex]

Answer:

Yes, A KLP can be reflected across the line containing KP and then translated so that Pis mapped to M.

Step-by-step explanation:

The figure shows two congruent by HA theorem (they have congruent hypotenuses and a pair of congruent angles adjacent to the hypotenuses) triangles KLP and QNM.

A rigid transformation is a transformation which preserves lengths. Reflection, rotation and translation are rigit transformations.

If you reflect triangle KLP across the leg KP and translate it up so that point P coincides with point M , then the image of triangle KLP after these transformations will be triangle QNM.

Triangle KLP can be reflected across the line containing KP and then translated so that P is mapped to M

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

Translation is the movement of a point either up, down, left or right in the coordinate plane.

There are 20 number of DVD's in Louis collection

Solution:

Let "J" be the number of DVD's with Jake

Let "B" be the number of DVD's with Bo

Let "L" be the number of DVD's with Louis

Given that Jake owns twice as many DVDs as Louis

So we can say,

number of DVD's with Jake = 2(number of DVD's with Loius)

J = 2L  ------ eqn 1

Given that Bo has sixty fewer DVDs than five times Louis’s collection

So we can say,

number of DVD's with Bo = 5 times number of DVD's with Louis - 60

B = 5L - 60 ---- eqn 2

Given that Jake and Bo have the same amount of DVDs

number of DVD's with Jake = number of DVD's with Bo

J = B ---- eqn 3

Let us solve eqn 1, 2, 3 to find value of "L"

From eqn 1 and eqn 3,

2L = B  ----- eqn 4

Substitute eqn 4 in eqn 2

2L = 5L - 60

2L - 5L = -60

-3L = -60

Thus there are 20 number of DVD's in Louis collection

Louis has 30 DVDs in his collection.

Let's denote the number of DVDs Louis has as L. According to the problem, Jake owns twice as many DVDs as Louis, so Jake has 2L DVDs. Bo has sixty fewer DVDs than five times Louis's collection, which means Bo has 5L - 60 DVDs.

Since Jake and Bo have the same amount of DVDs, we can set their quantities equal to each other:

2L = 5L - 60

Now, let's solve for L:

5L - 2L = 60

3L = 60

L = 60 / 3

L = 20

Louis has 20 DVDs in his collection.

Step-by-step explanation:

Let the first number be x and the second number be y.

Also , let x be the bigger number and y the smaller number.

From the first statement;

x + y = 33 ............................. equation 1

From the second statement

twice the smaller number = 2y

so, if the bigger number is 3 more than two times the smaller number, this means that

x = 2y + 3 .................................... equation 2

Solving the resulting linear equations by substitution method .

substitute x = 2y + 3 into equation 1 , that is

x + y = 33 becomes :

2y + 3 + y = 33

3y + 3 = 33

Cone:

h =  6 cm;

d = 3cm ; r = 3/2 = 1.5cm

Volume =(1/3)πr²h

             = (1/3) * π * 1.5 * 1.5 * 6

= π * 1.5*1.5 * 2 = 4.5π cu. cm

Hemisphere on top:

r = 1.5cm

Volume = (2/3)πr³

  =(2/3)* π * 1.5 *1.5 * 1.5

= 2 *π * 0.5*1.5*1.5

= 2.25π cu.cm

Volume of ice cream in each cone =  4.5 π + 2.25π = 6.75π cubic cm

No of cones = volume of cylinder/ Volume of ice cream in each cone

       =π *67.5 / 6.75 * π
