Answer:
slope of perpendicular line = -
Step-by-step explanation:
calculate the slope m of the given line using the slope formula
m =
with (x₁, y₁ ) = (1, 0) and (x₂, y₂ ) = (3, 3) ← 2 points on the line
m = =
given a line with slope m then the slope of a line perpendicular to it is
= - = - = -
Answer:
What is this asking
Step-by-step explanation:
Answer:
use substitution method
find equation for value of x/y
2x + 2y = 4
2y = 4 - 2x
y = <u>4 - 2x</u> ----> equation 1
2
so..substitute the
equation 1 to -5x+3y=-18
-5x+3( <u>4 - 2x</u><u> </u><u>)</u> = -18
2
-5x + 3(2-x) = -18
6-3x = -18+5x
6+18= 5x+3x
24 = 8x
<u>2</u><u>4</u> = <u>x</u>
8
x= 3. -----> eq.2
sub eq.2 into 1 to find the value of x
y = <u>4-2(3)</u>
2
y = - 1
x=3 ; y= -1
$1,365 is the answer, (the third choice)
