Answer: 17-3.99a
Step-by-step explanation:
Remove parentheses.
17- 0.07a- 3.92a17−0.07a− 3.92a
Collect like terms.
17+(−0.07a−3.92a)
Simplify.
17−3.99a
Answer:
Step-by-step explanation:
abs ( -2(5-(-1)) / 3 )
= abs ( -2(5+1) / 3 )
= abs ( -2(6) /3)
= abs (-12 /3)
= 4
(3(-1) -- 1) /2
= (-3 -1) /2
= -4 / 2
= -2
since 4 is greater than - 2 this is inequality is true
Answer:
The solution for y is y = 2x + 1
Step-by-step explanation:
* <em>Lets explain how to solve an equation for one of the variables</em>
- We need to solve the equation 16x + 9 = 9y - 2 x for y
- That means we want to find y in terms of x and the numerical term
- the equation has two sides, one side contains x and numerical term
and the other side contains y and x
- We need to separate y in one side, and other term in the other side
* <em>Lets do that</em>
∵ 16x + 9 = 9y - 2x
- Add 2x to both sides to cancel -2x from the right side
∴ 16x + 2x + 9 = 9y - 2x + 2x
- Add like terms in each side
∴ 18x + 9 = 9y
- Divide each term by the coefficient of y ⇒ (÷9)
∴ (18 ÷ 9)x + (9 ÷ 9) = (9 ÷ 9)y
∴ 2x + 1 = y
- Switch the two sides
∴ y = 2x + 1
* The solution for y is y = 2x + 1
