Equation #1:
Equation #2:
-4 is smaller than 13, so the solution to equation #1 is smaller than the solution to equation #2.
The answer is a.
We have been given a quadratic formula. we need to find the factors. the factors are multiplied by each other and gives rise to the quadratic formula
x² - 4x - 5
to find the factors we need to multiply x² by -5 = -5x²
then the factors of 5x² should add up to -4x.
possible factors of 5x² are 1x and 5x.
to get a negative product one factor should be positive and other factor should be negative. the sum of the factors is -4x, then the larger factor should be negative.
From 1x and 5x, larger factor is 5x therefore it should be -5x.
sum of 1x and -5x is -4x.
we write -4x in the quadratic formula as (1x - 5x)
x² + 1x - 5x - 5
taking the common factors out
x (x + 1) - 5 (x + 1)
(x-5) (x+1)
therefore factors are (x -5) and (x + 1)
answers are 1) and 4)
Answer:
2×(1+10)
Step-by-Step
You are just substituting in where the parenthesis go.
But I am not entirely sure.
X=$30
y=$60
1 hour job- 60x1=60+30=90
3 hour job-60x3=180+30=210
