Step-by-step explanation:

We have y = 9x - 70 and y = 2x - 32.

=> 9x - 70 = 2x - 32

=> 7x = 38

=> x = 38/7 which is around 5.43.

Answer:

Equations are :--- y = 9x – 70 and y = 2x – 32

Substituting the value of y, we get

9x - 70 = 2x - 32 \\ 7x = 38 \\ x =  \frac{38}{7}  \\  \boxed{x = 5.43} \\ y = 9x - 70 \\ y = 9( \frac{38}{7} ) - 70 \\ \boxed{ y =  - 21.14}

The rate at which a professional tennis player used carbohydrates during a strenuous workout was found to be 1.7 grams per minut
Alex787 [66]

Answer:

<em>m=1.7</em>

<em>C=68 gr</em>

Step-by-step explanation:

<u>Function Modeling</u>

We are given a relationship between the carbohydrates used by a professional tennis player during a strenuous workout and the time in minutes as 1.7 grams per minute. Being C the carbohydrates in grams and t the time in minutes, the model is

C=1.7t

The slope m of the line is the coefficient of the independent variable, thus m=1.7

The graph of C vs t is shown in the image below.

To find how many carbohydrates the athlete would use in t=40 min, we plug in the value into the equation

C=1.7\cdot 40=68\ gr

A can contains 11/12 pound of vegetables. One serving of these vegetables weighs 1/2 pound. What is the total number of servings
EleoNora [17]

11/12 is less than one.

Two servings would be 1/2 + 1/2 pounds, so exactly one pound.

It means that there is only one serving in a can, because there is not enough reminder for a second service

Find four consecutive odd integers such that 3 times the sum of the 1st and 2nd is 15 less than the fourth
jeka94

Answer: How do you find you four consecutive odd integers such as three times the sum of the first and the second is 15 less than the fourth?

Step-by-step explanation: So, the normal consecutive integers numbers are: 2,3,4,5. And the even consecutive integers numbers are: 2,4,6,8. And the odd consecutive integers are: 3,5,7,9. Consecutive integers formula are the algebraic representations of the consecutive integers. The formula to get a consecutive integer is n + 1.

Same as above, 7 is one of 4 consecutive integers, then the result is only 4 cases:

, 5, 6, 7

, 6, 7, 8

, 7, 8, 9

, 8, 9, 10

Hope this helps.
