Answer:
p = - 
Step-by-step explanation:
Given
p = 
( factorise numerator and denominator )
x² - y² ← is a difference of squares and factors as (x - y)(x + y)
x² + xy ← factor out x from each term
= x(x + y) , thus
p = 
← cancel (x + y) on numerator/ denominator
= 
← substitute x = - 4, y = - 6
= 
= 
= 
= -
The variables are the letters g and h because, t<span>he coefficient is the number in front of the variables (the letters are variables)</span>
Answer:I think you are correct
Step-by-step explanation:
We know she got one 100
But we don't know how many 85's she got
So we put x with 85 so (85x) plus the only 100 she got
Leading us too 440

Angles in the same segment are similar.
I'm not too sure how to explain, but in a circle when two "triangles" are formed from two same points on the circumference, the angle of the vertexes formed are the same (like in the picture)
Hey there! :D
y=2x-9
We can plug that in as y, since y is equal to 2x-9.
5x-3(2x-9)= 23
Distribute.
5x-6x+27= 23
-1x+27=23
Subtract 27 on both sides.
-1x=-4
Divide both sides by -1.
x=4
Now, plug that in for y.
y=2(4)-9
y=8-9
y=-1
(4,-1) <== solution
I hope this helps!
