If a line is perpendicular to other his slopes are the opposite inverse of each other
So, if y = -2x - 4 we have the slope of -2, so the slope of the other line will be the opposite inverse which means
opposite of -2 = 2
inverse of 2 = 1/2
So our slope is 1/2
(y - yo) = m.(x - xo)
(y - 4) = 1/2.(x - 3)
y - 4 = x/2 - 3/2
y = x/2 - 3/2 + 4
y = x/2 + 5/2
Answer:
88
Step-by-step explanation:
33 plus 55
Answer:
-5
Step-by-step explanation:
x = first number
y = second number
From the first sentence
11 = 2x + 3y
From the second sentence (I'm assuming the word "dust" should be "first"
y = 2-x
rewritten as
x + y = 2
So your system of equations is
2x + 3y = 11
x + y = 2
Multiply the 2nd equation by -2
2x + 3y = 11
-2x - 2y = -4
Add the two equations together
y = 7
Use y=7 to solve for x
x = 2-y = 2-7 = -5
Answer:
1360
Step-by-step explanation:
First, you do all the operations inside the parenthesis, and then you multiply the two. Also, remember the order of operations. Multiplication always comes before addition and subtraction.
(2.5x10-8)(9x10-10)
(25 - 8)(90 - 10)
(17)(80) = 17x80 = 1360
