How do i solve -3(2+4k)+7(2k-1)

2k - 13

Step-by-step explanation:

1. Because this is an expression, we can only simplify it.

2. (Solving)

Step 1: Apply distributive property.

Step 2: Combine like terms.

Therefore, the answer is 2k - 13!

6 adults and 9 children went.

a + c = 15

12a + 9c = 153

12(6) + 9(9) = 153

72 + 81 = 153

graph #4 (last graph) depict the function   f(x)= -m(x-d)^1/5 i

step-by-step explanation:

we know that

m=slope

but in this function slope is -m that means slope is decreasing and it is decreasing by 1/5 points down the x-axis.

which is shown in graph four

a decreasing slope down x-axis by 1/5 points.

hence 4th graph is the right option for this.
