Answer:
a) 150-90 = h(15.25 -9.75)
b) 10.91
Step-by-step explanation:
a) Jennifer has 150 -90 = 60 less in savings than Eduardo, but she is earning 15.25 -9.75 = 5.50 more per hour. An equation she can use to figure her hours is ...
60 = 5.50h . . . . for h hours worked.
In 'raw' form, that might be ...
150 -90 = (15.25 -9.75)h
__
b) Solving the above equation, we get ...
60/5.50 = h ≈ 10.90909 ≈ 10.91 . . . hours

Step-by-step explanation:
Candy draws a square design with a side length of x inches for the window at the pet shop. She takes the design to the printer and asks for a sign that has an area of 16x2 – 40x + 25 square inches. What is the side length, in inches, of the pet shop sign?
Answer:
the length of the sign is
inches
Step-by-step explanation:
Given
Area of the square of design = 
First we find the roots of equation 
The roots of the quadratic equation
are given by

where 






That is, the factors of the polynomial
are
and
.
So, Area of the square design =
= 
Area of a square = Length^2
Thus, the length of the sign is
inches
Answer:
This uses the method of elimination/addition.
Step-by-step explanation:
1 (9x + 7y = 15)
-7 (5x + y = -9) <— let’s eliminate y for both equations
9x + 7y = 15
+ -35x - 7y = 63 <— add both of the equations
—————————————————
- 26x + 0y = 6
(Please let me know if the answer is correct or not)
Answer:
y = 6x -2
