Answer:42 and 64
Step-by-step explanation:
Answer:
Blue - y=-2
Red-
Parallel to Red-
Perpendicular to Red-
Step-by-step explanation:
The slope intercept of a line is y=mx +b where
- m is the slope which is calculated as the vertical distance divided by the horizontal distance between two points.
- b is the y-intercept for value on the y-axis for which the line crosses it.
The Blue line intercepts the y-axis at -2 so b=-2. It has no vertical change since it is a horizontal line. This means the slope, m, is 0. m=0. It's equation is y=0x-2
y=0-2 since anything times 0 is 0.
y=-2.
The red line intercepts the y-axis at 2 so b=2. It intercepts the x-axis at (-3,0). Between these two intercepts we can find the slope:
Slope:
We substitute and
The red line has equation .
Parallel lines have the same slope with a different y-intercept. So we write a line where m=2/3 and b is something else.
Perpendicular lines have a negative reciprocal slope to the original. So we write the line where m/-3/2.
Answer:
Step-by-step explanation:
we have
we know that
The radicand must be greater than or equal to zero
so
Solve for x
Adds 4 both sides
Divide by 2 both sides
so
The domain is the interval for x ----> [2,∞)
All real numbers greater than or equal to 2
F x 3 = 5
f3=5
f = 5/3
an can also be f = 1 2/3
