-4× = 16 answer: -4
Step-by-step explanation:
-4 × -4 = 16
Using the quadratic formula works but if you know there are 2 answers (highest power of problem tells you how many solutions) then
10x^2 = 5x
So either x = 0, giving 0=0. Or divide by 5x
2x = 1
x = 0.5
If you would like to know the solution to the system of equations, you can do this using the following steps:
y = –5x + 3
<span>y = 1
</span>_______________
1 =<span> –5x + 3</span>
5x = 3 - 1
5x = 2 /5
x = 2/5 = 0.4
(x, y) = (0.4, 1)
The correct result would be (0.4, 1<span>).</span>
Answer:
Slope= 30
Speed = 30 miles per hour
Step-by-step explanation:
Given two points the slope will be change in y over change in x
OR (y-y1)/(x-x1)
(120-60)/(2-1) = 60/2 = 30miles/hr
