Answer: B. y=9
Explanation: divide both sides of the equation by three
y3/3 = y
27/3=9
y=9
hope this helps:)
Answer:
$90
Step-by-step explanation:
The shoes now cost 130% of the original cost
The original cost is 100%
Take the new amount and divide it by 130:
117/130 = .90
Then multiply that number by 100 to get the original percent
.90 x 100 = $90
To check, multiply $90 by 130% or 1.30 to make sure that a 30% increase makes the product $117
$90 x 1.30 = $117
Answer:
B. A cow of 5 years is predicted to produce 5.5 more gallons per week.
Step-by-step explanation:
Let
, where
is the age of the dairy cow, measured in years, and
is the predicted milk production, measured in gallons per week.
Besides, we consider
and
, such that
, we define the difference between predicted milk productions (
) below:
(1)
If we know that
and
, then the difference between predicted milk productions is:

That is, a cow of 5 years is predicted to produce 5.5 more gallons per week than a cow of 10 years. Hence, the right answer is B.

Answer:
y = 5x+3
Step-by-step explanation:
To find the slope, we need to points
(1,8) and (2,13)
Slope is given by
m = (y2-y1)/(x2-x1)
= (13-8)/(2-1)
= 5/1
The slope is 5
We can use the point slope form for an equation
y-y1 = m(x-x1)
y-8 = 5(x-1)
Distribute the 5
y-8 = 5x-5
Add 8 to each side
y-8+8 = 5x-5+8
y = 5x+3
This is in slope intercept form
