Answer:
39
Step-by-step explanation:
Are of rectangle -Area of triangle
= 45 - 6
=39
By "-21x + 9 + y equals -24x + 8" I'm assuming you meant
"y = -21x + 9 AND y equals -24x + 8." Using " + " to indicate "and" could be confusing.
We then have the system of linear equations
y = -21x + 9
y = -24x + 8
The function with the greater slope is the 2nd: y = -24x + 8 (with the understanding that we're focusing on the magnitude of the slopes). Thus, it is this function that changes more quickly.
Answer:
Step-by-step explanation:
A) (1+2x)-(2-3x)=
3x 1x = 2x
B) (-3+5x)-(-4x-5)
2x 1x = 1x
C) (x+1)-(-4x-5)
1x 1x x
The slope needs to be the same to be parallel So anything with the same slope and a different y intercept
For example y=-2x+ 10
Answer:
(5x³+3x²-5x+4) + (8x³-5x²+8x+9)
= 5x³+3x²-5x+4 +8x³-5x²+8x+9
= 5x³+8x³+3x²-5x²-5x+8x+4+9
= 13x³-2x²+3x+13
Hope this helps
