Answer:
Linear, the linear term is -21x and the constant term is -20. Last option is the answer
Step-by-step explanation:
We are given the following function:
First we have to simplify y, before solving the question:
Applying the distributive property:
No quadratic term, so it is linear.
The linear term is -21x and the constant term is -20.
Answer:
Step-by-step explanation:
a)
b)
c)
- 275 + 125x = 1850 - 100x
- 125x + 100x = 1850 - 275
- 225x = 1575
- x = 1575 / 225
- x = 7
The answer is 7 months
X= cost per cherry pie
y= cost per pumpkin pie
NICOLE
1x + 9y= $60
LISA
11x + 4y= $90
STEP 1
multiply Nicole's equation by -11
-11(1x + 9y)= -11($60)
multiply -11 by all terms
(-11 * x) + (-11 * 9y)= (-11 * 60)
-11x - 99y= -660
STEP 2
add Nicole's new equation from step 1 to Lisa's equation to solve for y (using the elimination method)
-11x - 99y= -660
11x + 4y= 90
the x terms "cancel out"
-95y= -570
divide both sides by -95
y= $6 per pumpkin pie
STEP 3
substitute y value into either original equation to solve for x
x + 9y= $60
x + 9(6)= 60
x + 54= 60
subtract 54 from both sides
x= $6 per cherry pie
CHECK
11x + 4y= $90
11(6) + 4(6)= 90
66 + 24= 90
90= 90
ANSWER: Each cherry pie costs $6 and each pumpkin pie costs $6.
Hope this helps! :)
Answer:
79
Step-by-step explanation:
The area of a circle is pi*radius^2; the radius of this circle is 10 (20/2=10). Our area is then 100pi or ~314 square feet. A 2x2 square takes up 4 feet. 314/4 is equal to 78.5, or when rounded, 79
