The graph represents the cost y (in dollars) to open an online gaming account and buy x games. Write an equation in slope-interc
Luba_88 [7]

Answer:

y = 10x + 15

Step-by-step explanation:

you pick two points on the line

I picked (3,45) and (6,75)

you subtract the two x’s and y’s

75 - 45 = 30 (30 is the rise) you go up from 45 to 75

6 - 3 = 3 (you move 3 times to the right to get to the 6) so 3 is the run

slope = rise/run so 30/3 = 10

The y-intercept is the place you start on the graph so that is 15

Ray PT is the angle bisector of angle RPS. Find the measure of angle RPS.
nikdorinn [45]

Answer:

m∠RPS = 38°.

Step-by-step explanation:

It is given that ray PT is the angle bisector of angle RPS. It means PT divides the angle RPS in two equal parts.

m\angle RPT=m\angle TPS=19^{\circ}

Now, it is clear that

m\angle RPS=m\angle RPT+m\angle TPS

m\angle RPS=19^{\circ}+19^{\circ}

m\angle RPS=38^{\circ}

Therefore, the measure of angle RPS is 38°.

Triangle ABC will be dilated according to the rule (x,y), where point F is the center of dilation. What will be the coordinates
Arturiano [62]
To dilate an object using a given scale factor we can multiply the coordinates of the object by the scale factor to get the coordinates of the image. However, this can only be done when the center of dilation is the origin (0,0). For non-origin center of dilation like in our case we have to locate the points of the image by construction in a Cartesian plane using the center and the scale factor. In this case we need to measure the distance of A from a point F (center of dilation) the we multiply it by 0.25 (the scale factor) then using the same path we measure the distance we get to locate point A'. Hence, by so doing point A' will be (1,0).
