Answer:
x = 7.2
Step-by-step explanation:
Since LO is an angle bisector then the following ratios are equal
= 
, that is
= 
( cross- multiply )
10x = 72 ( divide both sides by 10 )
x = 7.2
I think it would be y=(-9/5)x -1/9
It’s just a + b i think since the square root and the square cancel each other out
Answer:
C. a = 3
b = 7
c = -20
Step-by-step explanation:
x = -b+/- (sq) b^2 - 4ac.
Well the way to plug the numbers in is by using this equation: Ax^2 + Bx + C = 0
S if you use your equation : 3x^2 = 20 - 7x
First you have to move everything to one side.
So it'll look like this:
3x^2 = 20 - 7x
-20 -20
3x^2 - 20 = -7x
+7x +7x
3x^2 - 20 + 7x = 0
don't forget that... Ax^2 +Bx+ C= 0
3 = A
7 = B
-20 = C
Answer: see below
Step-by-step explanation:
coefficient: the numerical before a variable (3x)
constant: a number that is represented as an individual (5)
variable: any nonnumerical symbols (x)
-------------------
4x-7+15z-y+20
coefficient: 4 (4x), 15 (15z), -1 (-y)
constant: -7, 20
variable: x, y, z
