A company offers four plans for customers who want to rent DVDs and video games. The cost of the plans can be modeled by a linea
Luba_88 [7]
To solve this, we are going to use the slope formula, and the point slope formula.
Slope formula: m= \frac{y_{2}-y_{1}}{x_{2}-x_{1}}
where
m is the slope.
(x_{1},y_{1})  are the coordinates of the first point.
(x_{2},y_{2})  are the coordinates of the first point.
Point-slope formula: y-y_{1}=m(x-x_{1})

Plan A. Coordinates of the first point: (1,14) (number of discs, cost). Coordinates of the second point: (2,17). Lets replace those values in our slope formula:
m= \frac{y_{2}-y_{1}}{x_{2}-x_{1}}
m= \frac{17-14}{2-1}
m=3
Now that we have the slope, we can use the point slope formula:
y-y_{1}=m(x-x_{1})
y-14=3(x-1)
y-14=3x-3
y=3x+11
Remember that in a linear equation of the form y=mx+b, m is the slope and b is the y-intercept. In our model the y-intercept is the membership fee.
Since b=11 in our linear equation, we can conclude that the membership fee is $11

Plan B. Coordinates of the first point (1,12). Coordinates of the second point (2,16).
m= \frac{y_{2}-y_{1}}{x_{2}-x_{1}}
m= \frac{16-12}{2-1}
m=4
y-y_{1}=m(x-x_{1})
y-12=4(x-1)
y-12=4x-4
y=4x+8
Membership fee: $8

Plan C. Coordinates of the first point: (1,10). Coordinates of the second point: (2,15).
m= \frac{y_{2}-y_{1}}{x_{2}-x_{1}}
m= \frac{15-10}{2-1}
m=5
y-y_{1}=m(x-x_{1})
y-10=5(x-1)
y-10=5x-5
y=5x+5
Membership fee: $5

Part D. Coordinates of the first point: (1,12). Coordinates of the second point (2,21).
m= \frac{y_{2}-y_{1}}{x_{2}-x_{1}}
m= \frac{21-12}{2-1}
m=9
y-y_{1}=m(x-x_{1})
y-12=9(x-1)
y-12=9x-9
y=9x+3
Membership fee: $3

We can conclude that the plan that has the smallest one-time membership is <span>Plan D.</span>

Point slope formula is y= mx+b. To find the slope, or m, you need to find the "rise over run". rise = y coordinates, run = x coordinates. And the slope equation is y1-y2/x1-x2. So let's say the first point is (x1,y1) and the second is (x2,y2). that would be 35-(-31)/5-(-6)= 66/11 or 6/1 aka up six, across one. That is your slope. So far you have y=6x+b, next plug (5,35) into that equation and solve for b (aka the y intercept). So: 35=6(5)+b. 35-30=b, b=5. So your final equation is y=6x+5.

Use the distributive property of multiplication to find 6×24.<br><br> Hint: 24= 4+20.
Marina86 [1]

Answer:

see explanation

Step-by-step explanation:

6 × 24 ← replace 24 by 4 + 20

= 6(4 + 20) ← multiply each term in the parenthesis by 6

= 24 + 120

= 124
