0.25 r – 0.125 + 0.5 r = 0.5 + r . solve for r
Ivahew [28]
First, we need to get all of the r's on the same side.  To do this, we need to subtract "r" from both sides.

0.25r - 0.125 + 0.5r - r = 0.5 + r - r

0.25r - 0.125 +0.5r - r = 0.5

Now, we need to add like terms.

0.25r + 0.5r - r - 0.125 = 0.5

-0.25r - 0.125 = 0.5

Now, we need to get the "r" variable by itself.

-0.25r - 0.125 + 0.125 = 0.5 + 0.125

-0.25r = 0.625

Now, we divide both sides by -0.25

(-0.25r) / (-0.25) = 0.625 / (-0.25)

r = -2.5

If f(x) = 7x^2 - 3x +1 and g(x) = 3x - 2, find the following by matching.
Cloud [144]

f(x) = 7x² - 3x + 1

g(x) = 3x - 2


1. g(0) This means that x is 0, so you can plug in 0 for x in the equation:

g(x) = 3x - 2

g(0) = 3(0) - 2

g(0) = -2


2. g(1)    x is 1

g(x) = 3x - 2

g(1) = 3(1) - 2

g(1) = 3 - 2

g(1) = 1


3. f(1)     x is 1

f(x) = 7x²- 3x + 1

f(1) = 7(1)² - 3(1) + 1

f(1) = 7 - 3 + 1

f(1) = 5


4. f(x) = 7x²- 3x + 1

f(-2) = 7(-2)²- 3(-2) + 1

f(-2) = 7(4) + 6 + 1

f(-2) = 28 + 7

f(-2) = 35
