Answer:

The x intercept = -9

The y intercept = -12

Step-by-step explanation:

To find the x intercept, set y = 0 and solve for x

-4x - 3y = 36

-4x -0 = 36

Divide by -4

-4x/-4 = 36/-4

x = -9

The x intercept = -9

To find the y intercept, set x = 0 and solve for y

-4x - 3y = 36

0 -3y = 36

Divide by -3

-3y/-3 = 36/-3

x = -12

The y intercept = -12

Answer:

x = -9

y = -12

Step-by-step explanation: Substitute 0 for x & y to get your points.

-4x - 3y = 36

-4(0) - 3y = 36

0 - 3y = 36

-3y = 36

-3y    -3y

y = -12

-4x - 3y = 36

-4x - 3(0) = 36

-4x - 0 = 36

-4x = 36

-4       -4

x = -9

[tex]8x^2+7x-1=0\ \wedge\ 24x^2+53x-7=0\\\\\text{The equation:}\\\\24x^2+53x-7=8x^2+7x-1\qquad\text{subtract}\ 8x^2\ \text{and}\ 7x\ \text{from both sides}\\\\16x^2+46x-7=-1\qquad\text{add 1 to both sides}\\\\16x^2+46x-6=0\qquad\text{divide both sides by 2}\\\\8x^2+23x-3=0\\\\8x^2+24x-x-3=0\\\\8x(x+3)-1(x+3)=0\\\\(x+3)(8x-1)=0\iff x+3=0\ \vee\ 8x-1=0\\\\x+3=0\qquad\text{subtract 3 from both sides}\\\boxed{x=-3}\\\\8x-1=0\qquad\text{add 1 to both sides}\\8x=1\qquad\text{divide both sides by 8}\\\boxed{x=\dfrac{1}{8}}[/tex]

The values for x in the given equations, 8x^2 + 7x - 1 = 0 and 24x^2 + 53x - 7 = 0 are x = 1/4, x = -1/2, x = 1/8, and x = -7/6 respectively when the quadratic formula is applied.

To find the value of x for each equation, you will need to use the quadratic formula (x = [-b ± sqrt(b^2 - 4ac)] / (2a)). The quadratic formula is used in algebra to solve quadratic equations (polynomials of degree 2). The formula provides solutions for the variable x in terms of the coefficients of the equation, denoted as a, b, and c.

For the first equation, 8x^2 + 7x - 1 = 0, a = 8, b = 7, and c = -1. Plugging these values into the quadratic formula, the solutions come out to be x = 1/4 or x = -1/2.

Similarly, for the second equation, 24x^2 + 53x - 7 = 0, a = 24, b = 53, and c = -7. The solutions for x in this case come out to be x = 1/8 or x = -7/6.

Step-by-step explanation:

The height of the cylinder is 20 meters.

Given,

The formula for the volume of a cylinder is V=πr²h.

The cylinder to the right has an exact value of 180π cubic meters.

Its radius is given as 3 meters in the figure.

We need to find its height.

It is given by:

V = π r² h

Find the volume of the cylinder.

V = π r² h

We have,

V = 180π cubic meters

180π cubic meters = πr²h

Find the height of the cylinder.

We have,

180π cubic meters = πr²h

Divide both sides by π

180 cubic meters = r²h

We have,

r = 3 m

180 cubic meters = 3² square meters x h

180 cubic meters =  9 square meters x h

Divide both sides by 9.

20 meter = h

h = 20 meters

Thus the height of the cylinder is 20 meters.

Answer:

The sides are as follows: [tex]x=18,\,\,\,y=9\sqrt{3}[/tex]

Step-by-step explanation:

Starting with the side y, we can use the tan to solve for y:

Hey there!

Simple interest is based on only the original deposit of money, which in this case is $500.

To find 5.6% of 500, we can multiply it by the decimal that represents that part of a whole: 0.056.

[tex]500 \times 0.056 = 28[/tex]

The question asks for how much money is in the account after 8 1/2 years. This means we multiply the interest for 1 year (28) by 8 1/2.

[tex]28 \times 8.5 = 238[/tex]

Lastly, we add the interest to the original deposit.

[tex]500 + 238 = 738[/tex]

The answer is $738.

Answer:

because 3x6=18 so it will be the same problem

Step-by-step explanation:

The midpoint between the numbers 6 and -15 on a number line is -4.5. The distance between 6 and -15 on the number line is 21.

The midpoint on a number line between two points is found by adding the two points together and then dividing by 2. So, for points 6 and -15, the midpoint would be (6-15)/2 = -9/2 = -4.5. This means the midpoint between 6 and -15 on the number line is -4.5.

The distance between two points on a number line is found by subtracting the smaller number from the larger number and taking the absolute value. So, the distance between 6 and -15 is |6 - (-15)| = |-9| = 21. Therefore, the distance between 6 and -15 on the number line is 21.

Answer:

-5

Step-by-step explanation:

The integers are ..., -4, -3, -2, -1, 0, 1, 2, 3, 4, ... -- all the whole numbers and their opposites (the positive whole numbers, the negative whole numbers, and zero). Fractions and decimals are not integers. All whole numbers are integers (and all natural numbers are integers), but not all integers are whole numbers or natural numbers. For example, -5 is an integer but not a whole number or a natural number.

An example of an integer that is not a whole number is -1, as whole numbers are non-negative and -1 is negative.

The set of integers includes all the positive whole numbers, zero, and their opposites, which are the negative whole numbers. Whole numbers are defined as non-negative integers (0, 1, 2, 3, ...). Therefore, any negative integer like -1, -2, -3, and so forth, while being an integer, is not considered a whole number.

Step-by-step explanation:

8x + 10y = total revenue

if the total revenue is 830 then you can equate the above formula to 830 to give

8x + 10y = $830

Answer:

The required equation is [tex]8x+10y = 830[/tex].

Step-by-step explanation:

Consider the provided information.

As it is given that variable x represents the number of cars that paid to park and variable y represents the number of trucks that paid to park.

The cost of parking a car is $8 per day, the expression to represent the cost of parking x cars per day is 8x.

The cost of parking a truck $10 per day, the expression to represent the cost of parking y trucks per day is 10y.

The total revenue for the day was $830.

Thus, the equation represent the number of cars and trucks that paid to park that day is:

[tex]8x+10y = 830[/tex]

Hence, the required equation is [tex]8x+10y = 830[/tex].

Answer:

The ball will roll upto 1 m.

Step-by-step explanation:

A 1 kg ball has 10 joules of kinetic energy and starts to roll up a hill.

As along the hill the ball rises up, it loses its kinetic energy. The kinetic energy is converted to potential energy.

According to the law of conservation of energy, the kinetic energy plus the potential energy equals a constant.

Here given kinetic energy as 10 J, so this energy will get converted to potential energy.

We know that, potential energy is

[tex]P.E=m\cdot g\cdot h[/tex]

where,

m is the mass, g is the acceleration due to gravity and h is the height.

Putting the values,

[tex]\Rightarrow 10=1\times 10\times h[/tex]

[tex]\Rightarrow 10=10 h[/tex]

[tex]\Rightarrow h=1\ m[/tex]

Answer: There are 12 pink roses and 7 yellow roses.

Step-by-step explanation:

Since we have given that

Total number of members = 19

Let the number of pink roses be x

Let the number of yellow roses be 19-x

Cost of pink roses be $3

Cost of yellow roses be $2

Total amount spend to buy = $50

According to question,

[tex]3x+(19-x)2=\$50\\\\3x+38-2x=\$50\\\\x+38=\50\\\\x=\$50-\$38\\\\x=\$12[/tex]

Hence, Number of pink roses be 12

and number of yellow roses be

[tex]19-12=7[/tex]

Hence, there are 12 pink roses and 7 yellow roses.

To solve the problem, we set up two equations representing the number of team members and the total cost of roses, respectively. By solving these equations, we find that we should buy 8 pink roses and 11 yellow roses.

This problem is a type of algebraic word problem. We need to find out the number of pink roses and yellow roses to purchase with the total amounts of $50. Here's how we can solve this: Assuming that 'p' stands for pink roses and 'y' stands for yellow roses. We have two equations based on the problem:

By resolving these system of equations, the solution yields that you should buy 8 pink roses and 11 yellow roses.

Answer:

(-1, -1)

Step-by-step explanation:

Rotating the point (-1, -1) about the origin at -90° will be a 90 degree clockwise rotation.  This will map switch the x- and y-coordinates and negate the x-coordinate:

(x, y)→(y, -x)

(-1, -1) → (-1, 1)

Following this with a 90 degree counter-clockwise rotation will map

(x, y)→(-y, x)

(-1, 1)→(-1, -1)

This is the same point we started with.  Thinking about this logically, if we rotate something 90 degrees clockwise and then follow that with a 90 degree counter-clockwise rotation will put the object back in its original position.

Answer:

The correct option is 3.

Step-by-step explanation:

The coordinates of point P are (4,3).

We have to find the value of

[tex]R_{p,90}\circ R_{o,-90}:(-1,-1)[/tex]

The operations area operated from right to left it means first we have to apply

[tex]R_{o,-90}[/tex], then [tex]R_{p,90}[/tex].

[tex]R_{o,-90}[/tex] means rotation 90 degree clockwise about the origin, it is defined as

[tex](x,y)\rightarrrow (y,-x)[/tex]

[tex](-1,-1)=(-1,1)[/tex]

[tex]R_{p,90}[/tex] means rotation 90 degree counter clockwise about the the point P, it is defined as

[tex](x,y)\rightarrrow (-(y-3)+4,(x-4)+3)[/tex]

[tex](x,y)\rightarrrow (-y+7,x-1)[/tex]

[tex](-1,1)\rightarrrow (-1+7,-1-1)[/tex]

[tex](-1,1)\rightarrrow (6,-2)[/tex]

Therefore the coordinates of image are (6,-2). Option 3 is correct.

Let's go:

6x + 7 + 12x - 3 = 112

18x + 4 = 112

18x = 112 - 4

18x = 108

x = 6

mADB = 6.6 + 7 = 43°

I hope I helped you.

Answer:

43°

Step-by-step explanation:

Since we know that ∠ADC, which is the sum of ∠ADB and ∠BDC, is 112, we can solve for x:

112 = 6x + 7 + 12x - 3

112 = 18x +4

112 - 4 = 18x → 108 = 18x

108/18 = x → 6 = x.

Now, we can substitute 6 for x in the equation for ∠ADB to get the answer:

6(6) + 7 ⇒ 36 + 7 ⇒ 43°.
