Answer:

y=24-4x

Step-by-step explanation:

If you use this equation on any problem, you can see it will work. For (1,20) plug in the x and y variable, which is 20=24-4(1)

4(1)=4, so the equation is 20=24-4

24-4=20

20=20

Hi, there--

Question:

How do I graph y = -4x?

Solution:

Remember that you can represent an equation as a table and as a graph. I would start by build a table of ordered pair that make the equation true. For example,

When x is 0, y is -4*0 = 0. So, the ordered pair (0,0) is part of the graph.

When x is 1, y is -4*1 = -4. So, the ordered pair (1, -4) is part of the graph.

When x is -2, y is -4*-2 = 8. So the ordered pair (-2, 8) is part of the graph.

now we have a table that looks like this!

x y

0 0

1 -4

-2 8

You can keep going like this for as long as you want, but usually 3 of 4 points will give you a sense of what's going on.

Now we graph those points on an x-y coordinate grid.

We see that these points are part of a straight line. We can connect the dots. Every ordered pair on the line makes the equation y=-4x TRUE. Every ordered pair off that line makes the equation FALSE.

Step-by-step explanation:

Costs for Handsome Homes fabric

Area (sq. ft.) Cost (dollars)

(x) (y)

250 475

500 950

750 1,420

1000 1,900

If you divide any y-value by its corresponding x-value, the quotient will be 1.9

This means that each square foot costs $1.90 at Handsome Homes

Discount Diggers = 20% per sq. ft. less than Handsome homes

Discount Diggers = $1.90 - 20%

Discount Diggers = $1.90(100 - 20%)

Discount Diggers = $1.90(0.8)

Discount Diggers = $1.52

Now that it is known how much 1 square foot of fabric costs at Discount Diggers, we need to find how much 800 square feet of fabric costs.

$1.52 = 1 sq. ft.

$1.52(800) = 800 sq. ft.

$1,216

800 square feet of landscape fabric at Discount Diggers costs $1,216

Hope this helps :)

A theater has 60 seats on the front row. There are seven additional seats in each following row.

maksim [4K]

Answer:

(a) y(x)=53+7x

(b) 179

Step-by-step explanation:

Since the first row has 60 seats and next row has 7 additional seats then we can represent it as

First row=60

Second row=60+7=67

Third row=67+7=74

The difference is always 7. If you deduct 7 from dirst row we get 60-7=53 seats

To get rhe number of seats in any row x then let y be the number of seats in row x

y=53+7(x)

For raw 1

Y=53+7(1)=60

For raw 2

Y=53+7(2)=67

Therefore, the formula for number of seats at any row will be

y(x)=53+7(x)

(b)

Using the above formula

y(x)=53+7(x)

Replace x with 18 hence

Y(18)=53+7*(18)=179 seats

The terminal point of Dis ( 1/2,3/2). What is cos 0?

nydimaria [60]

Answer:

(c). $\frac{1}{2}$

Step-by-step explanation:

The cosine is the "x" coordinate of the terminal point on the unit circle.

Thus the answer is (c).  $\frac{1}{2}$
