Answer:
24ab-8ac
Step-by-step explanation:
Assuming you want to simplify it.
Original equation: 8a(3b+6c-7c)
Apply 8a to each variable in the paranthesis: (8a)(3b)+(8a)(6c)+(8a)(-7c)
After multiplication: 24ab+48ac-56ac
Combine like terms: 24ab-8ac
The answer would be 3z(5x + 7y)
The image is answer.................
Answer:
1) A = -10, B = -4, distance = 6 units
2) Eqaution: 3(x+4) = 60
Tyler's age: 16 Samantha: 20
3) x < 1
Draw a number line from 1 towards left, with an open circle at x = 0
Step-by-step explanation:
1) A/2 = -5
A = -5×2 = -10
8 = -B/0.5
8×0.5 = -B
B = -4
Distance = -4 - (-10) = -4 + 10 = 6
2) S = 4 + x
3s = 60
3(4 + x) = 60
3S = 60 S = 20
4 + x = 20 x = 16
3) x/2 + ¼ < ¾
x/2 < ¾ - ¼
x/2 < ½
x < 1
Draw a number line going towards left from 1, with an open circle at x=1 because x=1 is not included
Answer:
linear model
Step-by-step explanation:
This is a linear function. The initial value is 20 ft, and the yearly growth is 2ft/yr. Thus, the function is
height(t) = (20 ft) + (2 ft/yr)t, where t is the number of years.
