Answer:

x^2+3x+5 miles.

Step-by-step explanation:

We have been given that Joy is training for a triathlon. She runs a distance of 2x  miles, cycles a distance of (x^2+7) miles, and swims a distance of (x-2) miles. We are asked to find total distance covered by Joy.

\text{Total distance}=\text{Distance covered by running}+\text{Distance covered by cycling}+\text{Distance covered by swimming}

\text{Total distance}=(2x)+(x^2+7)+(x-2)

\text{Total distance}=2x+x^2+7+x-2

\text{Total distance}=x^2+2x+x+7-2

\text{Total distance}=x^2+3x+5

Therefore, Joy covered a total distance of x^2+3x+5 miles.

PLS HELP MEEEEEEEEE pls i make brain
Degger [83]

Answer:

1) 0.75

2) y = \frac{3}{4}x - 3

3) (4, 0); (0, -3)

Step-by-step explanation:

Convert to slope-intercept form (y = mx + b) by solving:

y = \frac{3}{4}x - 3

m is the slope, so \frac{3}{4} or you can write as 0.75.

To find the x and y intercepts, set the y value to zero and solve (x-intercept), and b is the y-intercept.
