Answer:
y = -2/5x + 9
Step-by-step explanation:
The slope will always be before the x. And intercept will always go after the slope. If your intercept is negative, remember to write it as x-9 rather than x+9.
And you'll always want to add the y = at the beginning
<span>B:she could divided both sides by 3 to get x+2=2y</span>
Answer:
Step-by-step explanation:
<span>When 2 people work the formula is:
Person1 * Person2 / (Person1 + Person2)
</span>
<span>rob becomes Person1 and Kayla becomes Person 2
9 * K / (9 + K) = 4.74 Hours
9*K = 4.74*9 + K*4.74
9*K = 42.66 + K*4.74
4.26 *K = 42.66
K = 10.014084507 hours (Kayla)
TESTING the answer
(9 * 10.014084507) / (9 + 10.014084507) = 4.74
90.126760563 / (19.014084507) = 4.74
4.74 = 4.74

Answer:
4x + 1 and 6x - 2x - 2 + 3
Step-by-step explanation:
we can expand and find 2 equations that are the same as this
one being 6x+3 -2x -2
and another being 4x + 1
hope this helps!
