1=2x^2-7
2x^2=8
x^2=4
so x=2 or x=-2
Answer:
Amanda > Todd > Derrick
Step-by-step explanation:
Amanda's IQR- 3.5
Derrick's IQR- 2
Todd's IQR- 3
Subtract five to both sides then subtract 2 to both sides then dived your y
Answer:
D
Step-by-step explanation:
to determine the relationship between these two lines you have to find the slope.
=> if they have the same slope ,then they are parallel.
=> if they have negative inverse slope relative to each other ,then they are perpendicular.
=> if the slope for both equations is neither of the above cases ,then the two equations are neither parallel nor perpendicular.
so if we divide the first equation by 3 which is the commen factor for the whole equation and arrange it in the form y=mx +b it would give us y =5x +4. and since the two have the same slope which is 5 ,then we can conclude they are <u>parallel lines.</u>
Answer:
A,
B
Step-by-step explanation:
If it's a 15 dollar variable fee and a flat 10 our equation looks like this
15c+10
which is the same as A
Now that we know the equation we can just plug a couple of numbers in
when c=3 what is h
15(3)+10=
55
THerefore the answer is B
