Answer:

y = mx + b would be your starting equation. You need two coordinates for to find your slope (mx). You multiple your slope (m) with your x-coordinate given (x). Then after multiplying, you subtract that with y to find your b. Thus, the answer. You'll want to ask yoru teacher for more help if you don't get it. :)

Peter spent half the money on his gift card and coffee and he loaded another $10 on the gift card how much was on the gift card

cestrela7 [59]

Answer:

$80 was on the gift card to begin with

Step-by-step explanation:

Let the initial money be x

Peter spent (1/2)*x

Peter added 10

Before adding more money on the gift card Peter had x -(1/2)x left on the gift card which is (1/2)x

After loading more money Peter had (1/2)x + 10

(1/2)x = 40 (money spent by Peter)

x/2 = 40

x = 80

A bus travels at a constant speed. The following table shows the distance the bus travels (in kilometers) over a period of time

Olegator [25]

Answer:

315 km

Step-by-step explanation:

If the bus travels at constant speed, then the slope of the distance versus time graph can be calculated by using any two points from this table.

Let's use the points (0.5, 42) and (4.5, 378):

as we move from the first point to the second, t increases by 4 and y increases by 336. Thus, the slope of this graph is

m = rise / run = 336 km / 4 hr = 84 km/hr

then distance traveled = speed times time, or

distance traveled = (84 km/hr)t, where t is the elapsed time.

In 6 hours the bus would travel

( 84 km/hr )(6 hr) = 504 km, or approx. 315 mi

In football a field goal is worth 3 points which function rule relates the number of field goals f and the number of points p

Strike441 [17]

The answer would be B. If you want to FIND how many points a person has, you put the "p" on its own on the left of the equation, and since every field goal (f) you score is worth 3 points, just multiply "f" by 3 (3f).

For example, if someone scored 5 field goals in a game, to find how many points they totalled, just plug in the 5 for "f":

1. Get equation:

p = 3f

2. Plug in field goals for "f":

p = 3(5)

3. Solve:

p = 15
