Answer:
6.5
Step-by-step explanation:
3X5=15
97.5/ 15 = 6.5
I think the answer is ten trillion, seven million.
Answer:
( - 7 + √17 ) / 2, ( - 7 - √17 ) / 2
Step-by-step explanation:
x^2 = - 7x - 8
x^2 + 7x + 8 = 0
Here,
a = 1
b = 7
c = 8
D = b^2 - 4ac
= 7^2 - 4 ( 1 ) ( 8 )
= 49 - 32
D = 17
x = - b ± √D / 2a
= - 7 ± √17 / 2 ( 1 )
x = ( - 7 + √17 ) / 2, ( - 7 - √17 ) / 2
Answer:
if 3 inches on a map = 42miles
then x = 322miles
cross multiply
3inches by 322 = xby42miles
966inchesmiles = 42xinchesmiles
divide both sides by 42miles
xinchees = 23
therefore 322miles distance will take 23inches on a map
No. Quincy should have used the trend line to find the corresponding x value when y=80.
