Answer:

\boxed{\sf a) \ 25}

Step-by-step explanation:

Angle PRQ is inscribed in a semi-circle, so the angle is a right angle.

4z - 10 = 90

Add 10 to both sides.

4z = 100

Divide both sides by 4.

z = 25

Find the equation of the line that contains the point (-1, -4) and is parallel to the line 6x+7y=13 . Write the equation in​ slo
sineoko [7]

Answer:  y=-\dfrac67x-\dfrac{34}{7}

Step-by-step explanation:

Slope-intercept form: y=mx+c   (i) , of linear equations,  m= slope and c= y-intercept of the line.

6x+7y=13in slope intercept form would be :

7y=13-6x\\\\\Rightarrow\ y=\dfrac{-6}{7}x+\dfrac{13}{7}

Comparing to (i) , m = \dfrac{-6}{7}

Slope of parallel lines are equal.

So, slope of required line = m = \dfrac{-6}{7}

Equation of line with slope m and passes through point : (y-b)=m(x-a)

So, equation of required line:

(y-(-4))=\dfrac{-6}{7}(x-(-1))\\\\\Rightarrow\ (y+4)=\dfrac{-6}{7}(x+1)\\\\\Rightarrow\ y+4=\dfrac{-6}{7}x-\dfrac{6}{7}\\\\\Rightarrow\ y=-\dfrac67x-\dfrac{6}{7}-4\\\\\Rightarrow\ y=-\dfrac67x-\dfrac{34}{7}

PLEASE HELP 50 POINTS
prohojiy [21]

Answer:

12 sales

Step-by-step explanation:

Let x represent the number of sales each man had.

For Salesman A, he earns $65 per sale; this is 65x.

For Salesman B, he earns $40 per sale; this is 40x.  We also add to this his weekly salary of $300; this gives us 40x+300.

Since their pay was equal, set the two expressions equal:

65x = 40x+300

Subtract 40x from each side:

65x-40x = 40x+300-40x

25x = 300

Divide both sides by 25:

25x/25 = 300/25

x = 12
