X - y = -5
-y = -x - 5
y = x + 5...slope here is 1. A perpendicular line will have a negative reciprocal slope. All that means is flip ur slope and change the sign. So our perpendicular line will have a slope of -1.
y = mx + b
slope(m) = -1
(4,7)...x = 4 and y = 7
now we sub and find b, the y int
7 = -1(4) + b
7 = -4 + b
7 + 4 = b
11 = b
so ur perpendicular equation is : y = -x + 11 <==
Hello!
A cube has 6 faces which is the shape of a square, all corners are 90 degrees and it’s x^3
Answer:
-13/30
Step-by-step explanation:
I used KCC. It is a method when you<u> keep you 1st # the same</u>, <u>change subtraction to addition</u> and then <u>change the last # to its opposite.</u> So after KCC, the equation would be -7/10 + 4/15
First, add 1 on both sides of the equation to begin to isolate x
x/5 = 8
Now, to isolate x, multiply both sides of the equation by 5/1
·
=
= x
x= 7 · 5/1 = 7 · 5 = 35
x = 35
