Step-by-step explanation:
A
d =sqrt ((x2-x1)^2 +(y2-y1)^2)
sqrt((12-2)^2 +(7--3)^2)
sqrt(10^2+10^2)
sqt(100+100)
sqrt(200)
sqrt(100)sqrt(2)
10sqrt(2)
Choice B
Answer:
y=2x
Step-by-step explanation:
We need to first find the slope. Lets get two points and apply the slope formula.
(1,2) and (2,4)
Rise: 2
Run: 4
Slope: 2
Then, lets use the standard way of showing a linear equation.
y=mx+b
y=2x+0
Answer:
504
Step-by-step explanation:
Answer:
4x − 30 = ≤12
Step-by-step explanation:
4x − 30 = ≤12
+30 on both sides
4x≤42
divided by 4 on both sides
x≤10.5
