Question

Need answer Asap please :) ​

Answer 1

1. 11

2. -82

3.
`(8)/(15)`

4. 36

5. 1

Explanation:

1. 3x + 5, when x = 2

Plug in the value of x

3(2) + 5 = 6 + 5

= 11

2. 5xy + x - 4, when x = -3 and y = 5

Plug in the values

5(-3)(5) + (-3) - 4

-75 - 3 - 4 = -82

3.
`(6ab - c)/(abc)`, when a = 5, b = 3, and c = 10

Plug in the values

`(6(5)(3) - 10)/(5*3*10)`

`(90 - 10)/(150)`

`(80)/(150)`

`(8)/(15)`

4. 3(xy + 6), when x = -6 and y = - 1

3(-6*-1 + 6)

3(6 + 6)

3(12)

36

5.
`(2x + 5)/(3x - y)`, when x = -3 and y = -8

`(2(-3) + 5)/(3(-3) - (-8))`

`(-6 + 5)/(-9 + 8)`

`(-1)/(-1) = 1`
