Answer:
Slope: 3.
Equation: y = 3x + 8.
Step-by-step explanation:
Lines that are parallel to each other will have the same slopes.
So, the slope of the new line will be 3.
Since we have the slope, and a set of coordinates the line passes through, we can find the equation. So far, we have y = 3x + b. x = -2, y = 2.
2 = 3(-2) + b
3(-2) + b = 2
-6 + b = 2
b = 8
So, the equation of the line will be y = 3x + 8.
Hope this helps!
I believe that the answer is B
Subtract 5x from both sides, 7x+2=-26, subtract 2 from both sides, 7x=-28, divide both sides by 7, x=-4
Answer:
6 * 10^2
Step-by-step explanation:
Simplify : (4.2×10^7)÷(7×10^4)
(4.2 × 10^7) / (7 × 10^4)
From indices : 10^a ÷ 10^b = 10^(a - b)
(4.2 / 7) * 10^(7-4)
0.6 * 10^3
= 6 * 10^2
Hence, (4.2×10^7)÷(7×10^4) = 6 * 10^2
5miles/8km = xmiles/80km
8x=400
x=50
