Can anybody solve this? Will give out 20 POINTS if you are SMART!

Answer:

y=x+9

Step-by-step explanation:

First, remove the parentheses.

Write in slope-intercept form. (y=mx+b)

The equation y--4=-2(x--1)

Answer:

y = 6

Step-by-step explanation:

You solve by using the pythagorean theorem, which is:

[tex]a^{2} +b^{2} =c^{2}[/tex]

Where a and b are legs of the triangle, and c is the hypotenuse, or y in this case. So let's rearrange this equation for c:

[tex]c=\sqrt{a^{2} +b^{2} }[/tex]

Now, we can substitute in the known values and solve:

[tex]c=\sqrt{3.6^{2} +4.8^{2} } = \sqrt{36} = 6[/tex]

Therefore, the value of y is 6

Since, a rectangle with a diagonal of length x is twice as long as it is wide, the area of the rectangle is (B) 2x²/5

Given that we have a rectangle with a diagonal of length x is twice as long as it is wide.

Let

Given that the length of diagonal, x is twice as long as it is wide, we have that

L = 2W

Also, since it is rectangle, we have that

D² = L² + W²

D² = (2W)² + W²

D² = 4W² + W²

x² = 5W²

W² = x²/5

W = x/√5

W = x√5/5

Since the length of the rectangle, L = 2W, we have that

L = 2W

= 2x√5/5

The area of the rectangle is given by A = LW where

So, A = LW

= 2x√5/5 × x√5/5

= 2x² × 5/25

= 2x²/5

So, the area of the rectangle is (B) 2x²/5

Answer:

domain: -2,-3, -1, 0, 1, 2

range: -2, -1, 0, 1, 2, 3

domain is the x value, range is for the y values

in this case, this isn't a line, it's just a line plot, so you just list the coordinates of where each point is for x and y.

Answer:

[tex] \boxed{y = - \frac{3}{4} x + 4}[/tex]

Step-by-step explanation:

The graph decreases. That meand the slope is in negative.

[tex]y = mx + b[/tex]

where m = slope and b = y-intercept. If the slope is positive, the graph will increase. Otherwise, decrease.

The only choice that the slope is negative is the third choice.

The value of the length of the newspaper is 21.52 inches and the width is 22.74 inches.

The rectangle is a geometrical figure in which opposite sides are equal.

The angle between any two consecutive sides will be 90 degrees.

Area of rectangle = length × width.

Perimeter of rectangle = 2( length + width).

Lets say,

Length of newspaper = l

Width of newspaper = w

Area of newspaper ( rectangle ) = l × w

Now,

Length is about 1.22 times its width.

So,

l = 1.22w

By substituting

1.22w × w = 630.92

1.22w² = 630.92

w² = 517.147

w = 22.74 inches

So,

l = 1.22 × 22.74

l = 21.52 inches

Hence "The value of the length of the newspaper is 21.52 inches and the width is 22.74 inches".

Answer:

Step-by-step explanation:

We can use a proportion to solve this.

Let x = how long the room is on the map

So, x/32 = 0.5/4

Cross multiply

4x = 16

Divide by 4

x = 4

Check

4/32 = 0.5/4

4 x 4 = 32 x 0.5

16 = 16

Answer:

red: 13/33

yellow: 12/33

blue: 8/33

Step-by-step explanation:

Add together all of the values to find the total amount of sections (13+12+8=33) --> this will be your denominator

From there, each time you make the numerator the number of that color, which gives you:

red: 13/33

yellow: 12/33

blue: 8/33

Answer:

$216

Step-by-step explanation

We know that we are paying 80% of the price of the airpods (20% off) so we can multiply the full price by 0.8.

250 * 0.8

This will give us 200.

Now, we need to add the sales tax which is 8%.

Simply multiply the 200 by 1.08 since we are paying the 200$ plus an extra 8% of the cost.

200 * 1.08 = $216

Answer:D

Step-by-step explanation:

you plug 4 in for x

f(4)=4^2+2(4)-3

=16+8-3

=24-3

=21

Step-by-step explanation:

We find the stationary point of (20 + 2x)(1200 - 60x),

where x is the unit rate of increase/decrease.

d/dx [(20 + 2x)(1200 - 60x)]

= d/dx (-120x² + 1200x + 24000)

= -240x + 1200.

When d/dx [(20 + 2x)(1200 - 60x)] = 0,

We have -240x + 1200 = 0. => x = 5.

Price per shirt that maximise revenue

= $20 + $2x = $20 + $2(5) = $30.

Maximum revenue

= (20 + 2(5))(1200 - 60(5))

= $30 * 900 = $27,000.
