Variables:
x: price/drink
y: price/bag of popcorn
system of equations:
72.50=5x+5y
163.50=15x+5y
solve:
(72.50=5x+5y)-1
163.50=15x+5y
-72.50=-5x-5y
----------------------
91=10x
x=9.1
163.50=15(9.1)+5y
163.50=136.5+5y
27=5y
y=5.4
One drink costs 9 dollars and 10 cents
First, let's ignore the answer choices and solve for a value of x ourselves.
2(8 - x) < 4
Distributive property.
16 - 2x < 4
Subtract 16 from both sides.
-2x < -12
Divide both sides by -2 (and flip the inequality sign)
x > 6
The value of x is going to be greater than 6, and so, we can observe the answer choices, and whichever value is greater than 6, is the correct answer.
<h3>In this case, there is only one answer, and that is D, x = 10.</h3>
Answer:
Step-by-step explanation:
8+1=9
8/9 ×100=800/9=88 8/9 %
1/9×100=100/9=11 1/9 %
This question doesnt make sense u need to attach a picture
Answer:
A.
The y-intercept of m is less than the y-intercept of n.
Step-by-step explanation:
y-intercept of a function:
The y-intercept of a function is the value of y when
Function n represents a cubic function that passes through the points (-1,0) and (0,2).
When , and thus, the y-intercept is y = 2.
Function m:
When , and thus, the y-intercept is y = -6, which is a smaller number than 2, so the y-intercept of m is less than the y-intercept of n, and the correct answer is given by option A.
