Answer:
find the lcm of 22,36,and 42
Step-by-step explanation:
lcm of 22 = 11 x 2
lcm of 36 = 2 x 2 x 3 x 3
lcm of 42 = 2 x 3 x 7
so the lcm of three numbers are 11 x 2 x 2 x 2 x 3 x 3 2 x 3 x 7 = 1000
Answer:
E) -3, 5
Step-by-step explanation:
x – 15 / x = 2
x^2 - 15 = 2x
x^2 - 2x - 15 = 0
(x - 5)(x + 3) = 0
x - 5 = 0; x = 5
x + 3 = 0; x = -3
Solutions: -3, 5
Answer:
3/-1
Step-by-step explanation:
The slope is 3/-1 (Rise 3 on the y axis, run to the negatives by 1 on the x axis)
To find the slope of two points, use the formula of y2-y1/x2-x1 (For example, with this equation it would be 10-4/10-12)
I'm not sure what it means to interpret the slope, but hopefully this helped you!
