Answer:
<h2><em><u>
15x</u></em></h2>
Step-by-step explanation:
4x(2x+3)-5x
4x(8x+3)-5x
8x+12x-5x
8x+12x=20x
20x+-5x=15x
I really hope this helps plz let me know if its wrong! Im sorry if it is!
Answer:
yes
Step-by-step explanation:
They are similar in shape but not bye mass
3(m + 5 + 9m)
A.
(1) 3m + 15 + 27m
(2) 3(10m + 5)
B. 3(m + 5 + 9m)....distributive property
(3 * m) + (3 * 5) + (3 * 9m) =
3m + 15 + 27m
C. 3(m + 5 + 9m) = 3(10m + 5)......m = 1
3(1 + 5 + 9(1) = 3(10(1) + 5)
3(1 + 5 + 9) = 3(10 + 5)
3(15) = 3(15)
45 = 45
a) find the slope of the line using the given points.
Slope: 9 - -3/6-0 then slope is 12/6 which is 2
Then using formula: y = mx+b
-3 = 2(0) + b
b = -3
The equation is: y = 2x -3
B. Slope of a perpendicular is -reciprocal of first line. So here the slope will be -1/2
y = mx + b is used again
2 = -1/2(0) + b
b = 2
The equation is: y = -1/2x +2
Answer:
(1,2)
Step-by-step explanation:
The solution to the system is where the two lines cross.
They cross at x=1 and y=2
