Answer:

1. A possible answer is:

y = x + 1
y = x - 3

Another possible answer

y = 3x + 2
y = 3x - 8

Another possible answer

y = 2x + 1
y = 2x - 7

2. There is no solution because the the lines are parallel to each others but are located at different y-intercept.

Step-by-step explanation:

1. The lines are parallel to each others which means they must have the same slope.

So you can choose the value for any slope you want.

The lines are increasing so the slope has to be positive. I just chose my slope to be m=1; it can be any positive numbers.

I will be using the slope intercept formula to plug in my values:

y = mx + b

Where m is the slope and b is the y-intercept value.

The first line is above the x-axis so it must have a positive b value for the y-intercept. I let the value be b=1 giving me:

y = x + 1

The second line is below the x-axis alot more than the first line, so the y-intercept must be negative. I just pick a random negative value and it was b=-3 giving me:

y = x - 3

The lines are parallel to each other, which means they will never touch each other. A solution to a system of equation can only exist if the line touch each other. Parallel lines that are separated at different points will never touch each other therefore there is no solution.

You are making a scaledrawing of a room using a scale of1 inch : 4 feet.a. The room is 14 feet by 18 feet. Find itsdimensions in

lilavasa [31]

Answer:

a. 3.5 inches by 4.5 inches

b. 1.5 inches

c. Divide 48 inches by 2 and multiply 1 inch by 12 to get a scale of 1 : 2

Step-by-step explanation:

A scale is a representative fraction showing the relationship between length on a drawing and actual length.

i.e scale = $\frac{length on a drawing}{actual length}$

scale = 1 inch : 4 feet

a. The dimensions in the drawing can be determined as;

1 inch : 4 feet implies an inch on the drawing equates 4 feet on actual length.

$\frac{14}{4}$ = 3.5 inches

$\frac{18}{4}$ = 4.5 inches

Dimensions on drawing is 3.5 inches by 4.5 inches.

b. The length of the sofa is 6 feet, its length on the drawing is;

$\frac{6}{4}$ = 1.5 inches

c. To enlarge the scale so as to double the dimensions of the drawing, we have;

12 inches = 1 feet

4 feet = 4 × 12 = 48 inches

given scale = 1 inch : 48 inches

Thus, divide 48 inches by 2 and multiply 1 inch by 12.

scale = 12 inch : 24 inch

scale = 1 : 2

To double the dimensions of the drawing, the scale required is 1 : 2. This implies that a unit measure on the drawing is synonymous to 2 measures on the actual reading.
