You have to do 2h up, halph an hour parallel , and then a line more vertical than the 2h, then parallel the time he is on the top, and then a line down that stops parallel for some time in the middle and then a line down to the bottom.

There you are almost but you have to do it with better measures.

If f(x) = 2x + 1 and g(x) = x^2 find g(f(3)) 49 19 7 13

valentina_108 [34]

Answer:

Step-by-step explanation:

Put the numbers in place of the variables and do the arithmetic.

g(f(3)) = g(2·3 +1) = g(7) = 7²

g(f(3)) = 49

A heart beats 264 beats in 3 minutes. What is the unit rate?

atroni [7]

What you need to do is divide the 264 by the minutes (3) to get 88 bpm, so i would say c.

Suzette ran and biked for a total of 44.75 mi in 4 h. Her average running speed was 6.5 mph and

vaieri [72.5K]

Suzette ran for 1.5 hours and biked for 2.5 hours.

a. Let x = total hours Suzette ran.

Let y = total hours Suzette biked.

The equation to solve the question will be:

x + y = 4 ....... i

6.5x + 14y = 44.75 ....... ii

b. x + y = 4 ....... i

6.5x + 14y = 44.75 ....... ii

From equation i, x = 4 - y

Put x = 4-y into equation into equation ii

6.5x + 14y = 44.75

6.5(4 - y) + 14y = 44.75

26 - 6.5y + 14y = 44.75

Collect like terms

-6.5y + 14y = 44.75 - 26

7.5y = 18.75

Therefore, y = 18.75/7.5

y = 2.5

Therefore, she bikes for 2.5 hours

Since x + y = 4

x = 4 - y

x = 4 - 2.5

x = 1.5

She ran for 1.5 hours.

Answer:

x = -2

Step-by-step explanation:

Given the point, (-2, 9) and the linear equation of a horizontal line, y = 6:

The linear equation of a horizontal line with a slope of zero (m = 0) is y = b, for which the y-intercept is (0, b). Perpendicular lines comprise of the intersection of two lines forming 90° angles.

Since we are given the equation of a horizontal line, then we can assume that the line that intersects a horizontal line must be a vertical line in order to form perpendicular lines.

The linear equation of a vertical line with an undefined slope is x = a, for which the x-intercept is (a, 0). Vertical lines have an undefined slope because these lines do not have any horizontal change. Thus, when you try to solve for its slope, the denominator will have a difference of 0, making the mathematical operation undefined.

We can use the x-coordinate of the given point, (-2, 9), to formulate an equation for a vertical line: x = -2.

Therefore, the equation of the line that goes through y = 6 is x = -2.

Attached is a screenshot of the graph of both equations, y = 6 and x = -2, showing that their intersection form 90° angles, making them perpendicular lines.
