The coordinates of r is ( 4, -1 )
Just multiply them so first multiply 2.7 times .9 and then times your answer by .6
<span>Problem 1: 2x > 4x - 6
2x < 6
x < 3
problem 2: -3r < 10 - r
-2r < 10
r > -5
problem 3: 5c - 4 > 8c + 2
3c < -6
c < -2</span>
The expected value of y when x is equals to 45 in the equation is 35.06
<h3>How to find variable from an equation?</h3>
The equation is given as follows;
y = -2.61x + 152.51
where
- x = variable 1
- y = variable 2
Therefore,
when
x = 45
y = -2.61x + 152.51
y = -2.61(45) + 152.51
y = - 117.45 + 152.51
y = 35.06
