The answer is actually d lol the idiot above me was right
Answer:
36
Step-by-step explanation:
AOB + BOC = AOC
AOC = 90 since the lines are perpendicular
6x-12 + 3x+30 = 90
Combine like terms
9x + 18 = 90
Subtract 18 from each side
9x+18-18 = 90-18
9x = 72
divide by 9
9x/9 = 72/9
x = 8
AOB = 6x - 12
= 6*8 - 12
= 48 -12
= 36
Answer:
y = (-3/2) x + 3
Step-by-step explanation:
The line passes through (0, 3) and (2, 0)
Slope = (0 - 3)/(2 - 0) = -3/2
Let y = (-3/2) x + b
Use (0, 3) to get b:
3 = (-3/2)*0 + b, so b = 3
Then y = (-3/2) x + 3
The answer is the sum of three times a number and six, divided by the difference of seven times a number and nine.
The phrase is(3p+6)/(7p-9)
Let’s describe each factor:
3p is three times a number
7p is seven times a number
3p+6 is the sum of three times a number and six
7p-9 is the difference of seven times the number and nine
The last two factors are divided, so
(3p+6)/(7p-9) is the sum of three times a number and six, divided by the difference of seven times the number and nine.
I hope this helped and have a nice day!
Start with the bottom equation and rearrange it so that it's a "y =" equation like so:
0 = 2x + 1 - y ->
y = 2x + 1
now since you know "y" you may substitute that equation 2x + 1 into "y" of the first given equation to be:
x^2 = (2x + 1) - 7 + 5x
then simplify
x^2 = 7x - 6 (I just put together like terms here to simplify the equation)
then you can make it to be: x^2 - 7x + 6 = 0
and there's your new and nice equation. now just solve for "x" using the quadratic formula or any other formula that you know
hope this helps
