I guess you need to solve for z:

-7(z+8) = 35
First, let's develop -7(z+8):
-7(z+8) = -7z -56

So -7(z+8) = 35
-7z - 56 = 35

Then we add 56 in both sides so we can get the variable on a side and the numbers on another:
-7z - 56 + 56 = 35 + 56
-7z = 91

Then divide each side by -7 so we can get the variable z alone on a side and its value on another side:
-7z = 91
(-7z)/-7 = 91/-7
z = -13

You can re-check your answer (very important):
-7(z+8) = -7(-13+8) = -7 * -5 = 35 (Multiplying negative numbers gives a positive number).
The answer has been approved.

Hope this Helps! :)

3241004551 [841]

Answer:

C. Quadratic model

Step-by-step explanation:

Determine what type of model best fits the given situation: Farmer Joe has 1,000 bushels of corn to sell. Presently the market price for corn is $5.00 a bushel. He expects the market price to increase by $0.15 per week. For each week he waits to sell, he loses ten bushels due to spoilage. A. none of these B. exponential C. quadratic D. linear

Given:

The quantity of corn Farmer Joe has to sell = 1,000 bushels

The present market price for corn = $5.00 a bushel

The amount by which he expects the market price to rise per week =$0.15

The number of bushels lost to spoilage per week = 10

The price of the corn per bushel with time = 5 + 0.15×t

The amount of corn left with time= 1000 - 10×t

Where;

t = Time in minutes

Value of the corn = Amount of corn left × Price of corn

Value of the corn = (1000 - 10×t) × (5 + 0.15×t)

=(1000-10t) × (5+0.15t)

=5,000 + 150t - 50t - 1.5t²

= -1.5t² +100t + 5000

Value of the corn= -1.5t² +100t + 5000.

It is a quadratic model

the expression y-x equals 0.7 if x and y have certain values. evaluate the following expressions with the same values of x and y
inessss [21]

Answer:

Step-by-step explanation:

y-x=0.7

y=x+0.7, so lets plug in that into the expressions instead of y

1)

(y-x)=

x+0.7-x=

x+0.7+(-x)=

x+(-x)+0.7=

x-x+0.7=

0.7

2)

(x-(x+0.7))/((x+0.7)-x)=

(x-x+0.7)/(x+0.7-x)=

(x-x+0.7)/(x+0.7+(-x))=

(x-x+0.7)/(x+0.7+(-x))=

(x-x+0.7)/(x+(-x)+0.7)=

(x-x+0.7)/(x-x+0.7)=

0.7/0.7=
