Once simplified, which of the expressions below is equal to −3x−39? Select all that apply.

1 answer:

3 0

It would be B. When you apply the distributive property (which is multiplying the outside integer on the outside of the parenthesis by the ones one the inside) you get -3 times x, which is -3x, and -3 times 13, which is -39 (it is negative because the positive times the negative is negative). This results in the solution -3x-39.

The function f(x) = -5x2 + 13x + 6 represents the height, in meters, of a

AnnZ [28]

Answer:

Step-by-step explanation:

Differentiate the function and set it to zero:

f'(x) = -10x + 13

0 = -10x + 13

x = 1.3 seconds

Plug the x value into f(x):

f(1.3) = -5(1.3)^2 + 13(1.3) + 6 = 14.45 meters

NikAS [45]

Answer:

0, 7 )

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 8x + 7 ← is in slope- intercept form

with y- intercept c = 7 ⇒ (0, 7 )

What is the solution to the system of equations graphed below?

Soloha48 [4]

Short Answer B
Remark
You need not do any calculations to get the answer. You are required just to read the graph. Doing the calculations would be beneficial but unnecessary.

Step One
Find the x value.
1. If you have a ruler or a straight edge of some kind, put it on the cross point of the two graphs.
2. Make the ruler go straight up and down. You will find out it goes 1 point back of the 5.
3. Count the number of squares from 0,0 or when y = 0.
4. You will find you have to count 4 squares along the x axis.

The x value is 4.

Step Two
1. Put the ruler on the cross point again. This time make it go straight across.
2. Count up from (0,0)
You should get 8.

The y value is 8
