Answer: -8x+13

Step-by-step explanation:

f(x) = −2x + 7

g(x) = 4x - 3

(fog)(x)=

f(g(x))=

f(4x-3)=

-2(4x-3)+7=

What’s the value of x?
Art [367]

Answer:

The answer is 28. I will explain below.

Step-by-step explanation:

Take a look at the angles, and determine what relationship they might be in. In this case, they are a pair of vertical angles. Recall that vertical angles are congruent, meaning the same measure. So set 3x+2 equal to 86, the equation looking like this:  3x+2=86. Now subtract the 2 from 86 to get 84, and you now have 3x=84. Divide 3x by three, and 84 by three. You should end up with x=28, and that's your answer.

What is an equation of the line that passes through the point (8,-7)(8,−7) and is parallel to the line 5x+4y=165x+4y=16?
Gnoma [55]

Answer:

The equation of line parallel to given line passing through (8,-7) is:

y = -\frac{5}{4}x+3

Step-by-step explanation:

Given line is:

5x+4y=16

first of all, we have to convert the equation of given line in slope-intercept form

4y = -5x+16

Dividing both sides by 4

\frac{4y}{4} = -\frac{5x}{4} + \frac{16}{4}\\y = -\frac{5}{4}x+4

Slope intercept form is:

y=mx+b

The slope of given line is:

m = -\frac{5}{4}

Let m1 be the slope of line parallel to given line

"The slopes of two parallel lines are equal"

m = m_1\\m_1 = -\frac{5}{4}

The equation of line parallel to given line will be:

y = m_1x+b

Putting the value of slope

y = -\frac{5}{4}x+b

Putting the point (8,-7) in the equation

-7 = -\frac{5}{4}(8)+b\\-7 = -(5)(2) + b\\-7 = -10+b\\b = -7 +10\\b = 3

Putting the value of b

y = -\frac{5}{4}x+3

Hence,

The equation of line parallel to given line passing through (8,-7) is:

y = -\frac{5}{4}x+3
