Answer:

B supplementary

C adjacent

Step-by-step explanation:

Vertical angles are across from each other and are equal False

Supplementary angles add to 180 degrees (if next to each other they form a straight line) True

Adjacent angles are next to each other True

Complementary angles add to 90 degrees (from a right angle) False

(1/8)^(x+2)=16^(2-x)

mixas84 [53]

1/8*2x=16*2x
devide 2x from both sides 1/8=16(x)
1/8=16x divide 16 from both sides
which is x=0.008

A company needs to replace 27 out of 45 desks in their office. What percent of the desks need to be replaced?

sleet_krkn [62]

60%

Solve by creating a proportion
27/45 = x/100

Cross multiply to get 2700=45x

Divide 45 on both sides to get x=60

Write in slope intercept form an equation of the line that passes through (-2,5),(-1,1)

Juliette [100K]

Answer:

y=-4x-3

Step-by-step explanation:

Hi there!

We are given the following two points: (-2,5) and (-1,1)

We want to write the equation of the line that passes through these two lines in slope-intercept form

Slope-intercept form is given as y=mx+b, where m is the slope and b is the y intercept

First, let's find the slope

The formula for the slope (m) calculated from 2 points is $\frac{y_2-y_1}{x_2-x_1}$ , where $(x_1, y_1)$ and $(x_2, y_2)$ are points

We have everything we need to calculate the slope, but let's label the value of the points to avoid any confusion

$x_1=-2\\y_1=5\\x_2=-1\\y_2=1$

Now substitute into the formula

m= $\frac{y_2-y_1}{x_2-x_1}$

m= $\frac{1-5}{-1--2}$
Simplify

m= $\frac{1-5}{-1+2}$

Subtract

m= $\frac{-4}{1}$

Divide

m=-4

Now substitute -4 as m into the equation:

y=-4x+b

Now we need to find b

As the equation passes through both (-2, 5) and (-1, 1), we can use either point to help solve for b.

Taking (-2,5) for example:

Substitute -2 as x and 5 as y:

5=-4(-2)+b

Multiply

5=8+b

Subtract 8 from both sides

-3=b

Substitute -3 as b.

y=-4x-3

Hope this helps!
