If 7(x+5) = -28 find the value of 6x

2 answers:

8 0

Answer:

-54

Explanation:

First we need to use the distributive property on 7(x+5), so do 7×x + 7×5. Simplify that and you get 7x+35.

Subtract 35 from both sides and you get 7x= -63. Divide both sides by 7 and you get x= -9.

Now we can substitute -9 for x, so do 6×-9 and you get -54.

Hope this helps :)

$7(x+5)=-28\\7x+(7*5)=-28\\7x+35=-28\\7x+35-35=-28-35\\7x=-63\\\frac{7x}{7}=\frac{-63}{7}\\x=-9\\\\6x=-54$

which function has the greatest rate of change? A. y = 7/6x + 2/3 B. y = 7/5x + 7/5 C. y = 6/5x + 11/5 D. y = 5/4x + 15/4

ddd [48]

Answer:

Step-by-step explanation:

In y = mx + b form, the slope can be found in the m position

y = 7/6x + 2/3......slope(m) = 7/6 or 1.167

y = 7/5x + 7/5....slope(m) = 7/5 or 1.4

y = 6/5x + 11/5...slope(m) = 6/5 or 1.2

y = 5/4x + 15/4.....slope(m) = 5/4 or 1.25

so the greatest rate of change would be B. y = 7/5x + 7/5 with a slope of 7/5

Mr. Scott times three fair coins. What is the probability that all three coins will land heads-up?

andrew-mc [135]

Answer:

3.3333 repeating

Step-by-step explanation:

This is the answer because if you take 100 percent or just 100, and divide that by the number of coins there are ( which there are 3 in this case) then you would get your answer which is 3.3333 repeating...

Hope this answer helps

For f(x) = 2x+1 and g(x) = x+14, find (gof)(x).

Goryan [66]

Answer: OPTION B

Step-by-step explanation:

You can observe that the exercise provides you two Linear functions.

The first Linear function is the function f(x). This is:

$f(x) = 2x+1$

And the other Linear function is the function g(x):

$g(x) = x+14$

In order to find $(gof)(x)$ , you need to follow these steps shown below:

<u>Step 1</u>:

You must substitute the function f(x) into the function g(x); this means that the function f(x) will be in the place of the variable "x" of the function g(x); as you can observe below:

$(gof)(x) = (2x+1)+14$

<u>Step 2</u>:

Finally you must combine the like terms (You can notice that the like terms are 1 and 14; then you must add them). Therefore, you get that $(gof)(x)$ is:

$(gof)(x) = 2x+1+14\\\\(gof)(x) = 2x+15$
