Answer:
140
Step-by-step explanation:
Let the number be represented by x. You are given ...
(3/5)x = 42
Multiplying by 10/3 gives ...
(10/3)(3/5)x = (10/3)(42)
2x = 140 . . . . the value of twice the number
The answer to the question
Answer:
1.49714285714
Step-by-step explanation:
6/7+4/5*4/5
=6/7+0.64
=1.49714285714
You would have to add x1 + x2 and divide by 2. do the same with y1 and y2.
(1/2,-1/2)
Answer:
y=3x+17
Step-by-step explanation:
Slope formula y2-y1/x2-x1=m
y=3x+b
Find b (y-intercept), enter the given coordinates (-3, 8)
8=3(-3)+b
8=-9+b
b=17
y=3x+17
