So your slope is 2 and your Y-intercept is 1.

To graph it, start at 0 and go up to number 2.

Ryan the trainer has two solo workout plans that he offers his clients: Plan A and Plan B. Each client does either one or the ot

Ivahew [28]

Answer:

Both plans last for 1.25 hours (1 hour 15 minutes)

Step-by-step explanation:

Let x hours be the time needed for plan A and y hours be the time needed for plan B.

On Wednesday there were 5 clients who did Plan A and 3 who did Plan B. Thus, 5x+3y=10.

On Thursday there were 2 clients who did Plan A and 6 who did Plan B. Thus, 2x+6y=10.

Solve the sytem of two equation. Multiply the first equation by 2, the second by 5 and subtract them:

$10x+6y-10x-30y=20-50,\\ \\-24y=-30,\\ \\y=\dfrac{30}{24}=\dfrac{5}{4}=1.25\ hours.$

Therefore,

$5x+3\cdot 1.25=10,\\ \\5x=10-3.75=6.25,\\ \\x=1.25\ hours.$

Find m angle T, rounded to the nearest degree

Butoxors [25]

Answer: First option.

Step-by-step explanation:

You can use the inverse tangent function to find the value of the angle T:

$\alpha=arctan(\frac{opposite}{adjacent})$

You can identify in the figure that:

$\alpha=T\\opposite=RG=8\\adjacent=TR=15$

Then, knowing these values, you can substitute them into $\alpha=arctan(\frac{opposite}{adjacent})$ .

Therefore, you get that the value of the angle T rounded to the nearest degree is:

$T=arctan(\frac{8}{15})\\\\T=28\°$

This matches with the first option.
