Solving for x...
Times the
, both the numerator and denominator, by 8 to get the denominator to 16.
Times the
, both the numerator and denominator, by 4 to get the denominator to 16.
Then rewrite the problem,
now that the denominators are all the same, you can solve...
subtract the
from both sides
you should get
Multiply both sides by 16 (it'll cancel both the 16 out making it go away)
8x = 11
divide each side by 8 to have the x alone
<u>8x</u> = <u>11
</u> 8 8
<u>
</u> You should end with x =
or 1.375<u>

Answer:
p(x) = x^2 + 5x
Step-by-step explanation:
p(x) = (x+5) (x <====== something may be missing here?
p(x) = (x+5) (x Use distributive property to expand R side
p(x) = x^2 + 5x
Answer: slope = -1,5
Step-by-step explanation:
We can use slope formula to find the slope of a line that passes through two points (x₁ , y₁) and (x₂ , y₂)
m = ∆y/∆x = (y₂ - y₁)/(x₂ - x₁)
Given points are: p(x₁ , y₁) = (5 , −9) and q(x₂ , y₂) = (−5 , 6)
Substituting these two known points in the slope formula, we have:
m = (6-(-9))/(-5-5) = 15/-10 = -1,5
Therefore, the slope of this line = -1,5
Answer: slope = -1,5
