Answer:
-x
Step-by-step explanation:
You can distribute:
(x + 3)(x – 4)
x (x + 3) – 4(x + 3)
x² + 3x – 4x – 12
x² – x – 12
Or you can use FOIL (first, outer, inner, last).
(x + 3)(x – 4)
x² – 4x + 3x – 12
x² – x – 12
Hey there!
(9) 2x-9y=45
... -9y=-2x+45
... y = (2/9)x - 5
Slope = 2/9
y-intercept = (0,-5)
(11) 3y+2x=-15
... 3y=-2x-15
... y = (-2/3)x - 5
Slope = -2/3
y-intercept = (0,-5)
(12) 10x+8y=40
... 8y=-10x+40
... y=(-10/8)x+5
Slope = -5/4 (after simplifying )
y-intercept = (0,5)
Hope my answer helps!
Answer:
5
Step-by-step explanation:
[ y - 3 = 5(x - 2) ] is written in point slope form [ y - y1 = m(x - x1) ] where (x1, y1) = any given points and m = slope. Looking at the equation, m = 5, so that is the slope.
Best of Luck!
Answer:
see below
Step-by-step explanation:
Except for the stretch factor, your work is completely correct. Multiplying only the x-coordinate by a factor of 2 results in a horizontal stretch by that factor.
Your coordinates and graph are correct.
In the comparison, you just need to say what happened.
Answer:
Step-by-step explanation:
<em>Look at the picture.</em>
<em />
We have:
Therefore
<em>divide both sides by 2</em>
