Mathematics
1 answer:
ruslelena [56]4 years ago
7 0

Answer:

x = 6

Step-by-step explanation:

−16=−4(2x−8)

<u>Let's rearrange so solving would be easier.</u>

-4(2x-8) = -16

<u>Let's open the brackets. Please take note of the signs (+) (-).</u>

(-4 * 2x) + (-4 * -8) = -16

-8x + 32 = -16

<u>Subtract </u><u>32</u><u> from both sides. Please take note of the signs (+) (-).</u>

-8x + 32 (-32) = -16 (-32)

-8x + 0 = = -48

-8x = -48

<u>Divide both sides by </u><u>-8</u><u>.</u>

-8x/-8 = -48/-8

x = 6

Given the function f(x) = 2x-5 and g(x), which function has a greater slope?​
adell [148]

Answer:

g(x) has a greater slope

Step-by-step explanation:

step 1

Find the slope of f(x)

we have

f(x)=2x-5

This is a linear function in slope intercept form

f(x)=mx+b

where

m is the slope

b is the y-intercept

so

m=2

step 2

Find the slope of g(x)

take two points from the table

(2,0) and (4,5)

m=(5-0)/(4-2)\\m=5/2=2.5

step 3

Compare the slopes

2.5 > 2

so

The slope of g(x) is greater than the slope of f(x)
