Answer:
.4 in or 2/5 in per month (.4 and 2/5 means the same one is in decimal and the other one is in fractions.
Answer: y = 1/2 or y = -1/2
Step-by-step explanation:
First move the 1 to the side with the 0
-4y^2 = -1 // -1 because when you move a number to the other side of the equation you have to multiply -1
Then divide by -4 on each side
y^2 = 1/4
square root each side
|y| = 1/2 // sq rt y^2 becomes an absolute value because when you square root a square it automatically becomes an absolute value
so the answer would be y = 1/2 or -1/2
to check just put it into the equation as y. Both work.

Answer: A.4Runner cost more for $11.02
B.Cost of fuel for Elentra: 3.75*3.59=$13.46
Cost of fuel for 4Runner : 6.818*3.59=$24.48
Step-by-step explanation:
A.Find how many gallons 4Runner spends on 150 mile trip.
use proportion
22:1=150:x
22x=150
x=150/22
x=6.818 gallons
Cost of fuel for 4Runner : 6.818*3.59=$24.48
Calculation for Elentra:
40:1=150:x
40x=150
x=150/40
x=3.75 gallons
Cost of fuel for Elentra: 3.75*3.59=$13.46
Cost of fule for 4Runner-Cost of fuel for Elentra=24.48-13.46=$11.02
4Runner cost more for $11.02
B.Cost of fuel for Elentra: 3.75*3.59=$13.46
Cost of fuel for 4Runner : 6.818*3.59=$24.48
Using a system of equations, it is found that the three consecutive even integers are -8, -6 and -4.
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the three consecutive even integers are represented by:
n, n + 2, n + 4
The first integer is two times the third, hence:
n = 2(n + 4)
2n + 8 = n
n = -8
Thus:
n = -8
n + 2 = -8 + 2 = -6
n + 4 = -8 + 4 = -4
The integers are -8, -6 and -4.
