A line has a slope of 2 and contains the points (1, 3) and (2, y). The value of y is

1 answer:

8 0

Y=mx+b

y=2x+b

point (1,3)

substitute to find b

3=2*1+b

3=2+b

b=1

equation is y=2x+1

point (2,y)

substitute to get y

y=2*2+1

y=4+1

y=5

point (2,5)

20baskets into 4minutes

Crank

Put this into ratio form:

20 baskets/ 4 minutes.

This means for every 4 minutes, you can make 20 baskets.

Now solve for 1 minute...how many baskets can you make in one minute.

You can solve this in many ways:

1. Cross Multiply:

20/4 = x/1...20×1= 20 ÷ 4= 5 baskets per minute

2. Simplify- (simpler way to solve)

20 baskets ÷ 4 minutes= 5 baskets in 1 minute

3. Critical Thinking:

how many times can 4 go into 20? 5 times. So there are:

5 baskets per minute

The daily cost of hiring a plumber , y , to work x hours on a repair project can be modeled using a linear function. The plumber

Paladinen [302]

Answer:

The range of the function is $80\leq y\leq 440$

Step-by-step explanation:

Consider the provided information.

The plumber charges a fixed cost of $80 plus an additional cost of $45 per hour.

Let plumber works for x hours, then the required linear function will be:

$y=45x+80$

The plumber works a maximum of 8 hours per day.

That means the minimum value of x is 0 and maximum value of x is 8.

We need to find the range of the function.

Range of the function is the set of y values.

Substitute x=0 in above function,

$y=45(0)+80$

$y=80$

Now substitute x=8 in above function.

$y=45(8)+80$

$y=360+80$

$y=440$

Hence, the range of the function is $80\leq y\leq 440$

What happens when you add and subtract like fractions

Cerrena [4.2K]

Answer:hey must have the same denominator (the bottom value). If the denominators are already the same then it is just a matter of either adding or subtracting the numerators (the top value). If the denominators are different then a common denominator needs to be found.
