replace f(x) wih y
solve for x
replace x with f⁻¹(x) and y with x
so
f(x)=3x+5/7
replace
y=3x+5/7
solve for x
minnus 5/7 both sides
y-5/7=3x
divide both sides by 3

=x
replace with f⁻¹(x)
f⁻¹(x)=
Answer:
1. right triangle - a triangle with one angle that measures 90 degrees
2.radius- a line segment from the center of a circle to any point on the circle
3. ray- a part of a line that has 1 endpoint that goes in one direction forever
4. rotational symmetry- a property that allows a figure to be rotated less than 360 degrees and still look the same
5. regular polygon- a polygon whose sides are all the same lengths and whose angles are the same measure
6. reflection- a transformation in which a figure is flipped across a line to give a mirror image of the original figure

Answer:
Slope= 7/5
Step-by-step explanation:
The slope of a line is determined as a ratio of the change in y to the change in x.
Slope=Δy/Δx
Δy=y₂-y₁
Δx=x₂-x₁
Therefore we can use the the x and y coordinates from the points given, (-3,0) and (2,7) to calculate the slope.
m= (7-0)/(2-⁻3)
Slope= 7/5
When a negative number is subtracted from a number it the operation sign changes to addition.
Answer:
x = 16.
Step-by-step explanation:
x - 4 = 3/4 x
x - 3/4 x = 4
1/4 x= 4
x = 4*4
x = 16 (answer).
