Answer:

I only know number 11 sorry :(

11. (Image attached)

Step-by-step explanation:

First, I would find the y intercept, which is 4. Next I found the slope of -3 by finding the rise of -3 (3 to left), then the run (1 up).

A computer monitor is listed as being 17 inches. This is the diagonal across the screen. If the screen measures 10 inches in hei
Aneli [31]

diagonal = sqrt(l^ + w^2)

17 = sqrt(10^2 + x^2)

17^2 = 10^2 + x^2

289 = 100 + x^2

189 = x^2

x = sqrt(189) = 13.747

X = 13.75

 width is 13.75 inches

Which of the following is a proportional relationship?
Solnce55 [7]

The two equations represent the proportional relationship.

y=3x and y=12x are proportional relation ship equations

proportion equations can be defined as

If we change x the y will change in the same proportion.

<h3>What is the proportional relationship?</h3>

Proportional relationships are relationships between two variables where their ratios are equivalent.

Another way to think about them is that, in a proportional relationship, one variable is always a constant value time the other.

That constant is known as the constant of proportionality.

proportional relationship equation contain (0,0) points

If we put x=0

This  will give us,y=0

If we put x=0, in y=12x

It will give y=0

put if we put x=0 in

y=3x it will give us y=0

hence these two equations represent the proportional relationship.

When ABC was dialed by a scale factor of 2, centered at the origin, the result was its image A'B'C' shown on the coordinates pla
sweet-ann [11.9K]

Answer:

Step-by-step explanation:

In dilation, the image and the original are similar, in that they are the same shape but not necessarily the same size. They are not congruent because that requires them to be the same shape and the same size, which they are not (scale factor is 2)

vertices of ABC are A(-2,2), B(-2,3), and C(1,2)

If we multiply by 2 from original to image,

then from image to original we divide by 2

Daisy made bread. The equation B = 4f shows the number of loaves of bread baked based on the amount of flour used, where B is th
Fynjy0 [20]

Answer:

k=4

Step-by-step explanation:

-The constant of proportionality  is defined as the ratio between two directly proportional variables.

-Given that B=4f

#The constant of proportionality is calculated as:

- the equation can be written in the form y=kx,

where y varies directly with x and k is the constant of variation:

y=kx\\\\k=\frac{y}{x}\\\\\therefore  B=4f\\\\\frac{B}{f}=4

Hence, B varies directly with f with a constant of proportionality k=4
