Answer:
y = -1/2x+4
Step-by-step explanation:
y = 2x-1
This equation is in slope intercept form y = mx+b where m is the slope
m=2
A line perpendicular will have a slope that is the negative reciprocal
m = -1/2
Using the slope intercept form
y = mx+b
y = -1/2x+b
and the point given (2,3)
3 = -1/2(2)+b
3 = -1+b
4 =b
y = -1/2x+4 is the equation of a line that is perpendicular to the original line and contains (2,3)
Answer:
180 degree rotation
Step-by-step explanation:
according to the picture, we can see the wheel made half of a full rotation before it stopped. a full rotation of a circle is 360 degrees, so the car made a rotation of half of 360, which is 180 degrees.
let's check our work!
a full ride on a ferris wheel is two full rotations, which is 720 degrees. Maria rode for 1/4 of a turn which we solved for 180 degrees.
180 x 4 = 720 degrees.
our answer is correct
So evaluate/subsitue
the equation becomes
(78 times 91+42)^2

do what's inside the parenthasees first
start over
parenthasees
exponents
multiplication and division yes 78 times 91
addition and subtraction so
78 times 91 is first
78 times 91=7098
addition
(7098+42)^2
(7140)^2
restart
parentasees simplified
exponents
7140^2=50,979,600
