A company finds it can produce 15 heaters for $ 4050â€‹, while producing 25 heaters costs $ 6550. Express theâ€‹ cost, y, as a l

amid [387]

Answer:

y=250x+300

Step-by-step explanation:

Let x be the number of heaters and y be the total cost.

We need to find the linear function for y in terms of x.

It is given that company can produce 15 heaters for $4050 and 25 heaters costs $ 6550.

It means the line passes through the points (15,4050) and (25,6550).

If a line passes through two points $(x_1,y_1)$ and $(x_2,y_2)$ , then the equation of line is

$y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

The equation of line is

$y-4050=\frac{6550-4050}{25-15}(x-15)$

$y-4050=\frac{2500}{10}(x-15)$

$y-4050=250(x-15)$

$y-4050=250x-3750$

Add 4050 on both sides.

$y-4050+4050=250x-3750+4050$

$y=250x+300$

Therefore, the required linear function is y=250x+300.

Finish the equation that satisfies the given conditions.

I’m not entirely sure what the question is asking because of the first word but the second equation (y=-x + 3) satisfies the conditions.

In the first game of the year, the modified basketball team made 62.5% of their foul shot free throws. Matthew made all 6 of his

Lesechka [4]

So 6 shots equals 25% of the teams total shots(x).
So 6=0.25(x)
x=6/0.25
x=24

If the team made 62.5% of their shots, then they missed 100%-6.25%=37.5%

37.5% of 24= 24(0.375)=9

Hope this helps

Chris plants 25 pumpkin seeds in 5 equal rows how many seeds does chris plant in each row ? Make an array to represent the promb

atroni [7]

Answer: 5 plants in each raw.

Step-by-step explanation:

Since, total number of plant = 25

According to the question, all rows are equal.

And, there are total number of rows = 5

Therefore, the number of plants in each row = total number of plant / total number of rows

= $\frac{25}{5}$

= 5

That is, In each row there are 5 plants.
