Answer:
1. Substitute y = -3x +4 for y in the first equation
2. Combine like terms and isolate x
3. Substitute in x into the 2nd equation to get y
Step-by-step explanation:
1. Substitute y = -3x +4 for y in the first equation
2x- (-3x+4) = 6
2. Combine like terms
5x -4 = 6
5x -4 +4 = 6+4
5x=10 Divide by 5 to isolate x
5x/5 =10/5
x=2
3. Substitute in x into the 2nd equation to get y
y = -3x +4
y = -3(2) +4
y = -6+4
y=-2
(2,-2)
Answer:
$0.75
Step-by-step explanation:
Answer:
exact form is 56/37
decimal form is 1.513
mixed number form is 1 19/37
Step-by-step explanation:
The answer is B
Because Mercury and the Sun are 60,000,00 miles apart and Mars is 200,000,000 miles away from the sun. Divide 200,000,000 and 60,000,000 and you will get 3.3 (Just round)
