Answer:
4) 2
Step-by-step explanation:
(4-0) / (1-(-1)) = 4/2 = 2
(10-4) / (4-1) = 6/3 = 2
Answer:
Okay
Step-by-step explanation:
There are 20 cassettes.
Step-by-step explanation:
Given,
Ratio of cassette to compact disc = 10:3
Let,
the number of cassettes = 10x
Number of compact disc = 3x
According to given statement;
the number of cassettes is 10 less than 5 times the number of compact discs.
10x = 5(Number of CD) - 10
Dividing both sides by 5
Number of cassettes= 10x = 10(2) = 20
There are 20 cassettes.

Answer:
1. x =8
2. x=9
Step-by-step explanation:
Since these figures are parallelograms, the opposite sides are equal.
1. 6 = 2x-10
Add 10 to each side
6+10 = 2x-10+10
16 = 2x
Divide each side by 2
16/2 = 2x/2
8 =x
2. x+14 =23
Subtract 14 from each side
x+14-14 = 23-14
x = 9
FIND THE SLOPE
The line passes through (0,1) and (2,0)
Use formula of the slope to find the slope
m = (y₂ - y₁)/(x₂ - x₁)
m = (0-1)/(2-0)
m = -1/2
The slope is -1/2
FIND THE Y-INTERCEPT
The y-intercept is the value of y when the line intersects y axis. The line intersects y axis in point (0,1). The value of y is 1. So the y-intercept is 1.
