Mel works as a delivery person for Amazon. The graph shows a linear model for his delivery times on
lakkis [162]

Answer:

Point slope form: -9 = m(3)

Slope intercept form: y = -3x + 30

At x = 0, his delivery time was 30 minutes. It decreased by 3 minutes per day.

Step-by-step explanation:

We have 2 points to calculate the line.

(3, 21) x1 y1

(6, 12) x2 y2

First, we need to calculate the slope.

m =

m =

m = -3

Point slope form is:

y - y1 = m(x - x1)

So for our case:

-9 = m(3)

And slope intercept form is:

y = mx + b

We need to solve for the y intercept (b)

y = -3x + b --- enter the slope

21 = -3(3) + b --- enter in any point on the line for x and y

21 = -9 + b

b = 30 --- solve for b

Now our slope intercept form of the line is:

y = -3x + 30

At x = 0, his delivery time was 30 minutes. It decreased by 3 minutes per day.

HELP ME PLZ
nadezda [96]

Answer:

BD does bisect the angle created by ABC, however it does not bisect segment AC. So it really depends on what you are determining the bisection to be.

Step-by-step explanation:

We can tell that it is bisecting the angle since it creates two congruent angles.

We can tell that it does not bisect the segment as AD and CD are not the same length.

Equivalent ration of <br> b/40=9/10<br> b=____ ?
NARA [144]

Answer:

The correct answer is <em>b = 36</em>

Step-by-step explanation:

In order to find out what b is, you must find out what 9/10 is.

9/10 is 0.9. This will later be used to check our answer.

Now, solve by using cross-multiplication

b * 10 = 9 * 40.

Then use the commutative property to reorder the terms

10b = 9 * 40

Now Multiply 9 * 40 = 360

10b = 360

Now divide both sides of the equation by 10

<em>b = 36</em>
