If f(x) = 7x+6 and g(x)=8x-4 find f(g(-2))

sp2606 [1]

Answer:

$f(g(-2))=-134$

Step-by-step explanation:

So we have the two functions:

$f(x)=7x+6\text{ and } g(x)=8x-4$

And we want to find f(g(-2)).

First, let's find g(-2):

$g(-2)=8(-2)-4$

Multiply:

$g(-2)=-16-4$

Subtract:

$g(-2)=-20$

Now, substitute:

$f(g(-2))=f(-20)$

Now, find the value of f(-20):

$f(-20)=7(-20)+6$

Multiply:

$f(-20)=-140+6$

Add:

$f(-20)=-134$

So:

$f(g(-2))=-134$

And we're done!

Twelve of the 40 cars pulled by the locomotive were tankers.

quester [9]

12 are tankesr
40 cars total
12/40
12/40=6/20=3/10

3/10=tankders
10/10-3/10=7/10
7/10=70/100=70%
70% wern't tankser

Let a, b, and c be constants, and let x be a variable. Which of the following is

Nonamiya [84]

Answer:

Step-by-step explanation:

We have:

$a(x+b)$

Where a<0.

We would like to solve for a. So, let’s divide both sides by a.

Notice that a<0. Therefore, a is negative. Hence, we must flip the sign since we are dividing by a negative. This yields:

$x+b>\frac{c}{a}$

Now, we will subtract b from both sides. Therefore, our inequality is:

$x>\frac{c}{a}-b$

Hence, our answer is C.

12. Find the value of x.<br> (11x - 151°<br> (5x - 13°

Step2247 [10]

Answer:

Step-by-step explanation:

I guess the angles are supplementary, which means they have a sum of 180º.

11x - 15 + 5x - 13 = 180

16x -28 = 180

16x = 208

x = 13

What is the exact value of x in the exponential equation 2^5x − 57 = 43?

katovenus [111]

Start by getting the term with the exponent on one side
$2^{5x}=100$

take the log of both sides
$log 2^{5x} =log100$

There is a log rule that says we can bring down the exponent
$5xlog2=log100$

Solve for x
$5x= \frac{log100}{log2}$
5x=6.64

answer: x=1.33
