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

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

Answer: x>18.64
Step-by-step explanation:
x+6.56-6.56>25.2-6.56
x>18.64
Answer:
Perpendicular
Step-by-step explanation:
2x - y = -7
2x + 4y = 2
-y = -2x - 7
4y = -2x + 2
y = 2x + 7
y = -1/2x + 1/2
Cannot be:
Parallel because the slope would otherwise be the same.
Same line because the equation is not proportional
So, they are perpendicular because a perpendicular line would be a negative and a reciprocal of the current line
Answer:
-8x^2+26x-21
Step-by-step explanation:
(3-2x)(4x-7)
12x-8x^2-21+14x
-8x^2+12x+14x-21
-8x^2+26x-21
