Answer:

Step-by-step explanation:

1) Write 8x+14 as 2(4x+7) and now multiply by 1/2 so that we get 4x+7

2)Subtract 7 from both sides

4x+7=39

-7 -7

4x=32

3) Divide by 8

x=8

Thus we get x=8 as answer

So reasons are

i) Distributive property

ii) Subtraction property of equality

iii) Division property of equality

Answer: x = 8

Step-by-step explanation:

1/2(8x+14) = 39 (given)

4x + 7 = 39 (open the bracket)

4x = 39 -7 (collect like term)

4x = 32 (divide bothside by 4)

4x/4 = 32/4

x=8

I believe you would take (114*34*2)+(114*1*2)+(1*34*2) equals 8048 squared feet of wrapping paper. I could be wrong. I found the areas of each side and added them together to get a total

For an exponential regression equation in the form y=ab^x which of the following values of b will cause y to get smaller as x ge

sdas [7]

Answer:

d) 0.798

Step-by-step explanation:

Since we know that an exponential function is in form: $y=a*b^x$ , where,

a= Initial value,

b = For growth b is in form (1+r), where r is rate in decimal form.

b = For decay or regression b is less than 1 and in form (1-r), where r is rate in decimal form.

Upon looking at our given choices we can see that options a, b and c are in form 1+r, while choice provided in option d is less than 1 and in form 1-r, therefore, option d is the correct choice.
