Answer:

Step-by-step explanation:

f(x) = 3x - 5

g(x) = - 2x + 7

<em>(a)</em>. <em>f(g(1)) = 10</em>

g(1) = - 2(1) + 7 = 5

f(5) = 3(5) - 5 = <em>10</em>

<em>(b).</em> <em>f(g( - 4)) = 40</em>

g( - 4) = - 2( - 4) + 7 = 15

f(15) = 3(15) - 5 = <em>40</em>

<em>(c).</em> <em>g(f( - 2)) = 29</em>

f( - 2) = 3( - 2) - 5 = - 11

g( - 11) = - 2( - 11 ) + 7 = <em>29</em>

<em>(d).</em> <em>g(f(3)) = - 1</em>

f(3) = 3(3) - 5 = 4

g(4) = - 2(4) + 7 = <em>- 1</em>

What’s is the slope of the lin
Lady bird [3.3K]

Answer:

1/3

Step-by-step explanation:

<em>Method 1.</em>

slope = rise/run

Rise is vertical distance.

Run is horizontal distance.

Find two points that are easy to read (on grid intersections):

(2, -1) and (5, 0).

Start at (2, 1). You need to go to (5, 0) by moving only vertically and horizontally. Go up 1 unit. That is a rise of 1. Now go right 3 units. That is a run of 3.

rise = 1

run = 3

slope = rise/run = 1/3

<em>Method 2.</em>

Use the slope formula and two points on the line.

slope = m = \dfrac{y_2 - y_1}{x_2 - x_1}

Use points (2, -1) and (5, 0).

slope = m = \dfrac{0 - (-1)}{5 - 2}

slope = m = \dfrac{0 + 1}{3}

slope = m = \dfrac{1}{3}

slope = 1/3

stich3 [128]

Answer:

A Between 1.43 in. and 1.47 in.

Step-by-step explanation:

If the circumference is between 9 and 9.25 inches, and we know that circumference equals 2 * pi * radius, we can solve to find that the radius equals the circumference divided by 2pi. So we get between 1.43 in and 1.47in
