Find the equation of the line that is perpendicular to 3y-x=7 and passes through the point (2,-1

boyakko [2]

Hello
<span>an equation for the line in point-slope form and general form is :
y = ax+b a : </span>slope ; the <span>Passing through (x' ; y')
</span>y' = ax'+b
y-y' =a(x-x') and : x' =2 y' = - 1
calculate a :
let : y = ax+b .....(D)
....<span>3y-x=7</span>....(D') or y = (1/3)x+7/3
.(D) perpendicular to(D') : slope (D) × slope (D') = -1

slope (D') = 1/3
slop(D)×(1/3) = -1
slope (D) = -3
equation for the line : y-y' =a(x-x')
y+1 =(-3) (x-2)

Find the annual earnings if a worker is paid $743.75 semimonthly.

Answer: A worker is paid $743.75 semimonthly.

Semimonthly is twice a month.

Therefore, a worker is paid $ $743.75 \times 2 =1487.5$ monthly

There are 12 months in a year.

Therefore a worker is paid $ $1487.5 \times 12 =17850$ annually

Hence, the option b. $17,850.00 is correct

PLEASE HELP ASAPPP!!! 15PT QUESTION!!! Suppose that a ball is rolling down a ramp. The distance traveled by the ball is given by

Sever21 [200]

Answer:

The average velocity of the ball is $137.5 \:ft/sec$

Step-by-step explanation:

First find the velocities at given times and then form two points. Calculate the slope to find the average velocity. The two points are:

$\left(6,\:396\right)\quad and \quad \:\left(6.5,\:464.75\right)$

$\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}=\frac{464.75-396}{6.5-6}$

$m=137.5$

Best Regards!
