Answer:
D
Step-by-step explanation:
To find a situation for 60−15x≥7, look for a story where 60 is a constant value that is decreasing by 15 for a number of times and where equal to or at least 7 is an option.
A. x would be weeks and it would decrease by 7x. This is not it.
B. 15 songs packages would have x be the number of packages not the price. This is not it.
C. This doesn't work either because if you want to owe them less than 7 it would have the sign < not >.
D. You have 60 to spend and you decrease it by $15 for each hat you buy till you save $7. This is it.
r/v + a = 5
subtract a from both sides
r/v = 5-a
multiply by v on both sides
r = v*(5-a)
You can use C=2*pi*r and A=pi*r^2
Answer:
There is no hole
Step-by-step explanation:
2x^2-10x+12 = 2(x-2)(x-3) zeros: x=2 or x=3
x^2-3x-2=0 zeros: x=(3±√17) / 2
the numerator and denominator do not have any common factor
Answer:
The answer is -8 (Option B)
Step-by-step explanation:
You can solve this by replacing x in the equation with 8, because the question give us what x equals. So instead of y=8-2x, we get y=8-2(8)
Now that we have the complete equation, we can solve for y:
y= 8 - 2x
y= 8 - 2(8)
y= 8 - 16
y= -8
