Answer: 11 boxes of cards for $72
Step-by-step explanation:
Brennan's equation would be
y=6x+6
Gabriel's Equation would be
y=5x+17
when they spend the same amount the equations will be equal
6x+6=5x+17
x+6= 11
x=11
so 11 boxes they would spend the same
To figure out cost, put 11 into the first equations
y=6(11)+6= 66+6= 72
y=5(11)+17= 55+17 = 72
so they each spent $72
Answer:
1/25
Step-by-step explanation:
Well, in order to figure this out, we need to figure out how many times 4 goes into 100, because it is 4 out of 100%.
So if you divide 100 by 4 you get 25, which means 4 goes into 100 25 times.
So the fraction would be 1/25 of the number.
Hope this helps :)
Just plug -3 where x is into the equation 2x^2 + 6 and solve
f(-3) = 2(-3)^2 + 6
f(-3) = 2(9) + 6
f(-3) = 18 + 6
f(-3) = 24
Y=mx+b
m=slope=rise/run
if slope>0, then it increases
if slope<0, then decreases because it is going down
y=7-2x
y=-2x+7
-2<0
decreasing
because the y values decrease from left to right
the x values always increase if you go from left to right
B is the answer
I'd go with Checking account B because its cheaper .
