Answer:
x = 2
Step-by-step explanation:
For quadratic ax^2 +bx +c, the axis of symmetry is x = -b/(2a).
Here, we have a=2, b=-8, so the axis of symmetry is ...
x = -b/(2a) = -(-8)/(2(2)) = 8/4
x = 2
Answer:
A.
Step-by-step explanation:
1/5 is a rational number so A is false. Just to prove this ill show every other answer is true.
B is true because rational; numbers have a repeating pattern while irrational do not.
C is true as any number not involving i is a real.
D is true as all integers have a repeating pattern if turned into decimal form.
Ok this is a bit complicated.
Total: 114 days
114 divided by 3 equals 38
38 times 2 equals 76
76 books, I think.
Answer:
y=3/4m
Step-by-step explanation:
All proportional relationships have the form y=mx where m is the rate of change from the families donations x to the business donations y. We can find the rate of change m by substituting values we already know. We know when x=$12 then y=$9.
9=m*12
We solve for m by dividing by 12 on both sides.
m=9/12
This simplifies to 3/4 so
m=9/12=3/4.
The equation is y=3/4m
