Answer:
(1/2,4)
Step-by-step explanation:
First, determine y in first equation: 2x+y=5 or y=5-2x
replace value of y determined in first equation (5-2x) into 2nd equation
4x-3(5-2x)=-10
4x-15+6x=10
10x=5
x=1/2
put value of x into either equation to solve for y so
2(1/2)+y=5
1+y=5
y=4
answer: x=1/2, y=4
check answer by substituting x and y into either equation:
4x-3y=-10
4(1/2)-3(4)=-10
2-12=-10
-10=-10
or
2x+y=5
2(1/2)+4=5
1+4=5
5=5
Answer:
4.6875 is the answer
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
Given
- 12 ≤ 2x - 4 < 10 ( add 4 to all 3 intervals )
- 8 ≤ 2x < 14 ( divide all 3 intervals by 2 )
- 4 ≤ x < 7
I believe that the answer is -18.
