Graph the line with slope -3 passing through the point (2,4)
sveticcg [70]

Answer:

f(x) = -3x + 10

Step-by-step explanation:

Substitute values to find b;

y=mx+b

y=-3x+b

<em>Replace X and Y</em>

4=-3(2)+b

4=-6+b

<em>Swap sides to set equal to b. Swapping causes sign change</em>

4+6=b

10=b

triangle JKL is rotated 270 degrees counterclockwise about the origin to form triangle jkl what is the y-coordinate of point j
IRINA_888 [86]

The y-coordinate of point j' in the image triangle J'K'L' is -x coordinate of point j in the initial triangle JKL.

Step-by-step explanation:

The rule to apply here is that of 90° clockwise about the origin.

This is to say that: rotation 270° counterclockwise about the origin applies the same rule as rotation 90° clockwise about the origin.

In this case, If point j has coordinates (x,y) then after the rotation j' will have coordinates (y,-x)

So the y-coordinate of point j' in the image triangle J'K'L' is -x coordinate of point j in the initial triangle JKL.

olga nikolaevna [1]
Cost = 15x + 2000
Earning = 35x

At break even, cost = earning

35x = 15x + 2000
20x = 2000
x = 100

100 rides are needed to break even.

Answer:

1. 5

2. 12

3. a. 12

3. b. 18

Step-by-step explanation:

1. 50 - 45 = 5.

2. 26 - 18 = 8. 30 - 18 = 12. 12 + 8 = 20. 20 + 18 = 38. 50 - 38 = 12.

3. a. 24 - 12 = 12.

4. 40 - 12 = 28. 24 - 12 = 12. 28 + 12 + 12 = 52. 70 - 52 = 18.
