What is the solution to the system of equations?

y = –5x + 3

y = 1

Answer:

The answer is isosceles , obtuse.

Step-by-step explanation:

I say this because if you look at the shape of the triangle, isosceles  are longest on the bottom and make it look stretched, and the top is obtuse because it is over a 90 degree angle

Answer:

Step-by-step explanation: It is an isosceles triangle and it is obtuse. So the answer would be the second one.

if triangles are similar then corresponding internal angles are equal

=》 x = 180-(50+60) = 70degrees

The measure of angle x is the same as the measure of angle c which is,

x = 70°

A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.

We know triangles that are similar to each other have equal measures of corresponding angles.

Given, ΔABC ≈ ΔEDF,

Therefore, m∠B = m∠E = 50° and m∠D = m∠A = 60.

So, The measure of angle x is,

x = 180 - 50 - 60. (sum of interior angles equals 180°)

x = 180 - 110.

x = 70°.

21 + 2w = 16

as you know 21 is 2l,

one length

2l = 21

l =21/2

l = 10.5

Answer

10.5 inches

Answer:

[tex]l=8-w[/tex]

Step-by-step explanation:

We have been given that the perimeter of a rectangle is 16 inches. The equation that represents the perimeter of the rectangle is [tex]2l+2w=16[/tex], where [tex]l[/tex] represents the length of the rectangle and w represents the width of the rectangle.

Let us solve for [tex]l[/tex].

Factor out 2:

[tex]2(l+w)=16[/tex]

Divide both sides by 2:

[tex]\frac{2(l+w)}{2}=\frac{16}{2}[/tex]

[tex]l+w=8[/tex]

Subtract w from both sides:

[tex]l+w-w=8-w[/tex]

[tex]l=8-w[/tex]

Therefore, the expression [tex]8-w[/tex] represents length of rectangle.

[tex]\large\boxed{(f+g)(x)=x^2+3x-3}[/tex]

Step-by-step explanation:

[tex](f+g)(x)=f(x)+g(x)\\\\f(x)=3x-5,\ g(x)=x^2+2\\\\\text{Substitute:}\\\\(f+g)(x)=(3x-5)+(x^2+2)=3x-5+x^2+2=x^2+3x+(-5+2)=x^2+3x-3[/tex]

Final answer:

To find (f+g)(x) for the given functions f(x)=3x-5 and g(x)=x²+2, you simply add the two functions to get (f+g)(x) = x²+ 3x - 3.

Explanation:

Adding Functions f(x) and g(x)

To find (f+g)(x), you simply need to add the values of f(x) and g(x) together for any value of x. Given that f(x)=3x-5 and g(x)=x²+2, the sum (f+g)(x) is obtained as follows:

Take the expression for f(x) and g(x):

f(x) = 3x - 5

g(x) = x² + 2

Add the two expressions together:

(f+g)(x) = f(x) + g(x)

(f+g)(x) = (3x - 5) + (x² + 2)

Combine like terms:

(f+g)(x) = x² + 3x - 3

The resulting function (f+g)(x) = x² + 3x - 3 is the sum of the two functions f(x) and g(x).

Answer:

The answer is (A) ⇒ G(x) = 7(-x)³

Step-by-step explanation:

* In transformation:

- Reflecting across the y-axis means change the sign of x-coordinate

- Stretch vertically means multiply f(x) by constant k, where k > 1

∵ F(x) = x³

- At first we reflect it across the y-axis

∴ We must change the sign of x to -x

∴ F(x) = (-x)³

- At second we stretch it vertically by constant 7

∴ We multiply F(x) by 7

∴ F(x) = 7(-x)³

∴ The answer is (A) ⇒ G(x) = 7(-x)³

In the graph the red is F(x) , the blue is G(x)

Step-by-step explanation:

given

x + 4 > - 8 ( subtract 4 from both sides )

x > - 12 ← solution

The step to use is subtract 4 from both sides

The value of x is -12

x + 4 > -8

Subtract 4 from both sides

x + 4 -4 > -8 -4

x > -12

Some factoring lets us write

[tex]a^{2b}-\dfrac1{a^b}=a^{2b}-a^{-b}=a^{-b}(a^{3b}-1)[/tex]

Then

[tex]8a^{3b}=1\implies a^{3b}=\dfrac18[/tex]

[tex]a^{2b}-\dfrac1{a^b}=a^{-b}\left(\dfrac18-1\right)=-\dfrac78a^{-b}=-\dfrac7{8a^b}[/tex]

Taking the cube root to solve for [tex]b[/tex], we find

[tex]\sqrt[3]{a^{3b}}=\sqrt[3]{\dfrac18}\implies a^b=\dfrac12[/tex]

so ultimately

[tex]a^{2b}-\dfrac1{a^b}=-\dfrac7{8\cdot\frac12}=-\dfrac74[/tex]

Answer:

The value of the given expression is    1 - 1 = 0

Step-by-step explanation:

8a^{3b} = 1   can be rewritten as (8a³)^b = 1 = (8a³)^0, which indicates that b = 0.  If b= 0, then 2b = 2(0) = 0.

Then a^(2b) = a^0 = 1, and 1/a^b = 1/1 = 1.

Thus, the value of the given expression is    1 - 1 = 0

Answer:

11058 m³

Step-by-step explanation:

This is a slanted cylinder.  The volume is V = (area of base) (height), just as in the case of upright cylinders.

Here, V = πr²·h.  Subbing the givens,

          V = π(8 m)²·(55 m) = 11058 m³ is the volume of this building.  I have                   rounded this result off to the nearest 1 m³.

First divide 1/4=0.25 and then multiply 0.25 bu 100% so the result is 25%

For the dumonitor remember that 4 x 25 is 100.

Our Multiple is 100.

So that means we need to multiply 1 and 4 by 25.

1×25 = 25 so our top number is 25.

4x25 is 100 which would be our bottom number.

We end up with 25/100.

That as a percent would be [tex]\fbox{25percent}[/tex] / 25%

Answer:

[tex]y + 1 = -\frac{5}{6}(x-6)[/tex]

or

[tex]y = -\frac{5}{6}x +4[/tex]

Step-by-step explanation:

Parallel lines are lines which have the same slope. To write the equation of the line parallel, find the slope of the equation 5x + 6y = 6 through conversion into slope intercept form.

5x + 6y = 6 becomes y = -5/6x + 1. The slope is -5/6.

Substitute\ m =-5/6 and the point (6,-1) into the slope intercept form.

[tex]y-y_1=m(x-x_1)\\y --1 = -\frac{5}{6}(x - 6)\\y + 1 = -\frac{5}{6}(x-6)[/tex]

Convert the equation to slope intercept form by applying the distributive property.

[tex]y + 1 = -\frac{5}{6}(x-6)\\y + 1 = -\frac{5}{6}x +5\\y = -\frac{5}{6}x +5-1\\y = -\frac{5}{6}x +4[/tex]

https://brainly.com/question/78672

Fractions less than 3/4 have a numerator to a denominator ratio that equals a number less than 0.75. Examples of such fractions are 1/2 and 2/3.

To determine which fraction is less than 3/4, it's important to remember that a fraction represents a division: the numerator (upper number) divided by the denominator (lower number). Fractions that are less than 3/4 have a ratio of the numerator to the denominator that results in a number less than 0.75, which is the decimal equivalent of 3/4.

For example, the fraction 1/2 is less than 3/4, because 1 divided by 2 equals 0.5, and 0.5 is less than 0.75. Similarly, the fraction 2/3 is less than 3/4, because 2 divided by 3 equals approximately 0.67, and 0.67 is again less than 0.75. Knowing the division values, even approximately, can help you quickly figure out if a fraction is less than or greater than another one.

The answer choice which matches the graph we drew is Option (A)

In mathematics, inequality is a statement of an order relationship that can be greater than, greater than or equal to, less than, or less than or equal to between two numbers or algebraic expressions.

Coordinate axes is the graph of the X and Y axis . A straight line can be plot in the coordinate axes plane by identifying its slope and the value of its y-intercept.

Given equation of straight line is y + 2 < 1/4x - 1

We solve the inequality in standard form of equation of straight line,

y < 1/4x - 3 , where slope is 1/4 and y-intercept is 3 when comparing with y = mx + c.

From the four graphs given in the Option, each and every graph has a slope of 1/4 and a y-intercept of -3 .

In Option (A) the portion indicating in the graph is the region which is less than -3 . Also from the equation, y < 1/4x - 3 we can see that the variation of the curve will always be less than -3 and it will also be a straight line and not a dotted line.

So the graph of Option(A) satisfies the straight line and inequality.

x=1

Step-by-step explanation:

f(x) = 1/3 (x+5) (x-1)

We want to find the zero's so set f(x) = 0

0 = 1/3 (x+5) (x-1)

Using the zero product property

x+5 = 0   x-1 =0

x+5-5 = 0-5      x-1+1 = 0+1

x = -5                  x=1

Answer:

x = -5, 1

Step-by-step explanation:

first you want to set both parenthesised equations to zero --

x + 5 = 0        x - 1 = 0

then just solve the one step equations--

x + 5 = 0      x - 1 = 0

  -5     -5        +1     +1

x = -5           x = 1

and you can leave the 1/3 alone (it actually has nothing to do with the zero product property)
