Answer:
The slope of line is .
Step-by-step explanation:
Given points are:
(1, 14) and (8, 6)
x1 = 1 and y1 = 14
x2 = 8 and y2 = 6
Slope of a line is given by formula;
Therefore,
The slope of line is .
Answer:
2
Step-by-step explanation:
y = 2x +7
so,
if x=0 then y =2 x 0 +7 =7
if x=1 then y =(2 x1) +7 =2+7=9
if x=2 then y =(2 x2)+7 = 4+7 =11
if x=3then y =(2 x3) +7 = 6+7 =13
if x=4 then y =(2 x4) +7 =8+7 =15
if x=5 then y =(2 x5) +7 = 10+7 =17
To solve this, first make an equation:
After you solve this, you get x = 1.0399, but we have to subtract 1 so we get 0.0399 which is
3.99%
The first one:
5v + 3 = 5v - 5
Subtract 5v from both sides ->
3 = -5
This isn't true so that means there are no solutions...
