8 days—> because if you 160 insurance is already added, subtract that to get your original price since that’s what is actually being counted.
So I did 760-160=600
600/75=8
Also your answer is D.
Yes because 2/9 is equal to 12/56 so if you do 2/9 times 6/6 you would get 12/56. YUR WELCOME NO PROBS
Answer:
X= 2
y = 2
Step-by-step explanation:
y=-2x+6............... equation 1
y=3x-4................... equation 2
from equation 2
y=3x-4
substitute y=3x-4 in equation 1
3x-4=-2x+6
collect like terms
3x+2x=6+4
5x=10
divide both sides by 5
X=2
substitute X=2 in equation 1
y=-2x+6
y=-2(2)+6
y=-4+6
y=2
hope it helps

there's a quick graph below of the bounds and the tangent at "c"
not happening -2 or 2 will have a tangent parallel to a,b, needless to say -2 is out of the range [a,b] anyway, so the only value is really 1, on the positive 1st quadrant
