Answer:
Multiproperty
Step-by-step explanation:
To solve this problem, we use different properties to arrive at our answer.
Given expression;
4(x + 3) = 20;
First we use the distributive property to expand;
4x + 12 = 20
Now use subtraction property by adding (-12) to both sides;
4x + 12 + (-12) = 20 + (-12)
4x = 8
you can now divide by 4,
x = 2
The equation of a line is:
y = mx + c
The m is the gradient of the line, and the c is the y-intercept of the line
That means that the y-intercept of [y = -4x + 3] is 3
and the y-intercept of [y = -4x + 4] is 4
So the distance between the two y-intercepts is:
4 - 3 = <u>1</u>

Answer:
reflected across the x-axis is 3,-2 and the y axis is -3,2
Step-by-step explanation:
When you reflect over the X axis it will stay the same numbers but change the Y axis sign. the same thing happens to the y -axis but the x changes siogns instead
