Answer:

Step-by-step explanation:

4x-6y=21

divide by 21

\frac{4x}{21} -\frac{6y}{21} =1\\or~\frac{x}{\frac{21}{4} } +\frac{y}{-\frac{7}{2} } =1\\x~intercept =\frac{21}{4} =5.25 \\y~intercept=-\frac{7}{2} =-3.5

Answer:

Step-by-step explanation:

To find the y-intercept, let x = 0 and solve the remaining equation for y:

4x - 6y = 21 => 4(0) -6y = 21, or  y = -21/6, or (after reduction) y = -7/2.  Thus the y-intercept is (0, -7/2).

To find the x-intercept, set y = 0 and solve for x:

4x - 6y = 21   =>  4x = 21  =>  x = 21/4.  The x-intercept is (21/4, 0).

A rental car company charges $35 a day plus $.15/mi for a mid-size car. A customer owes $117.25 for a three-day rental. How many
Molodets [167]
The base charge is 35 dollars per day. He rented the car for 3 days, so before you add in the mileage you have to multiply 35 x 3 days for 105 dollars. Then you have to take the remaining charge and divide it by the charge per mile to get the number of miles driven.  Lets set up the equation.

d= number of days rented
m= number of miles driven

35(d) + .15(m) = 117.25
35(3) + .15m = 117.25
105 + .15m = 117.25
.15m = 117.25 - 105
.15m = 12.25
m = 12.25/.15
m = 81.67

So he drove 81.67 miles

Can someone help on a construction of a tangent to a circle please, need pictures if possible
Anit [1.1K]

Wassup

Steps:

1. Draw a line connecting the point to the center of the rectangle

2. Then construct a perpendicular bisector to the line drawn in step 1

3. Place the compass on the midpoint of the line, adjust its length to reach the end point, and draw an arc across the circle

4. Where the arc crosses the circle will be the tangent points. So connect the endpoint to the tangent point

Hope the picture helps you too
