Answer:
x = -1 and y = 6
Step-by-step explanation:
using x = -b/2a
x = -4 / 2(2)
x = -1
y = 2(-1)² + 4(-1) + 8
y = 2 - 4 + 8
y = 10 - 4
y = 6
Answer:
(2)/(3) =( 4)/( 3+x)
Cross multiply
2*(3+x)= 4*3
Solve bracket
6+2x=12
Subtract 6 from both sides
2x=6
Divide both sides by 2
x=3
Hope it helps :-)
The answer is negative, because the first number is negative.
Answer:
Hey there!
a)
10x-1=4x+2
6x-1=2
6x=3
x=1/2 cm.
10x-1=4 cm.
So the width of the rectangle is 10/4, or 2.5 cm.
b)
l=3w
2l+2w=24
2(3w)+2w=24
6w+2w=24
8w=24
w=3
l=9
The are is 27 units squared.

Answer: The sum of three dollars and the product of 50 cents times the number of miles is nine dollars and fifty cents.
Three dollars plus $0.50 times the number of miles is equal to nine dollars and fifty cents.
Step-by-step explanation:
Hi, to answer this question we have to analyze the equation given:
3.00 + 0.50 m = 9.50
Where m is the number of miles.
The equation states that the fixed fee charged (3.00) plus the product of the value of each mile traveled (0.50) and the number of miles traveled (m); is equal to 9.50.
So, the correct statements are:
- The sum of three dollars and the product of 50 cents times the number of miles is nine dollars and fifty cents.
- Three dollars plus $0.50 times the number of miles is equal to nine dollars and fifty cents.
