Answer:

7+2(a-3)=-9

a= -5

Step-by-step explanation:

7+2(a-3)=-9

<u>Distribute</u><u> </u> 2 through the parentheses

<u>Example</u><u>:</u> 7+2a-6=-9

Next: 7+2a-6=-9

Subtract the numbers

1+2a=-9

Move constant to the right hand side and change its sighn 2a=-9-1

<u>2a</u><u>=</u><u>-9-1</u>

<u>Calculate</u><u> </u><u>the</u><u> </u><u>difference</u><u> </u>

2a=-10

<u>Divide</u><u> </u><u>both</u><u> </u><u>sides</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>equation</u><u> </u><u>by</u><u> </u><u>2</u>

<u>Answer</u><u>:</u><u> </u>a=- -5

Which function has the same rate of change as fx= 3x+5​
alexandr1967 [171]

Answer:

Step-by-step explanation:

The rate of change is defined as the derivative of the function, or also known as the slope. The derivative here would be 3. Another function which has the same rate of change would be any function with a slope of 3. A few example are:

f(x) = 3x + 1

f(x) = 3x + 2

Help! i need to answer this before 11:59pm EST, Today !!, i would appreciate your help.
Arada [10]

Answer:

0.18 sec or 3.4 sec.

For second part, it will take 3.7 sec.

First part:

Set h(t) = 17and solve for t.

-16t²+ 58t + 7= 17

-16t² + 58t - 10 = 0

Solve this quadratic equation for t. You should get 2 positive solutions. The lower value is the time to reach 17 on the way up, and the higher value is the time to reach 17 again, on the way down.

Second part:

Set h(t) = 0 and solve the resulting quadratic equation for t. You should get a negative solution (which you can discard), and a positive solution. The latter is your answer.
