Answer:

Cost of each roast beef sandwich = $7

Cost of each ham sandwich = $8

Step-by-step explanation:

x = cost of each roast beef sandwich

y = cost of each ham sandwich

2x + 5y = 54 (1)

5x + 3y = 59 (2)

Multiply (1) by 5 and (2) by 2

10x + 25y = 270

10x + 6y = 118

Subtract to eliminate x

25y - 6y = 270 - 118

19y = 152

Divide both sides by 19

y = 152 / 19

= 8

y = $8

Substitute y = 8 into (1)

2x + 5y = 54 (1)

2x + 5(8) = 54

2x + 40 = 54

2x = 54 - 40

2x = 14

x = 14 / 2

x = $7

Cost of each roast beef sandwich = $7

Cost of each ham sandwich = $8

Can somebody help me with this one. It says use the vertical line test to determine which graph represents a function
sineoko [7]

Answer:

Only option C shows a function

Step-by-step explanation:

The vertical line test is a visual way to determine if a curve is a graph of a function or not. A function can only have one output, y, for each unique input, x. This means that a vertical line made in the domain of the function can crosses the curve of the function only once. If it crosses the curve of the function more than once, then the curve is not a function.

In option A, a vertical line would cross two values, so it is not a function.

The curve of option B is a vertical line itself, so a vertical line would intersect an infinite amount of points; then it is not a function.

Option C is a function because a vertical line would only intersect the function's curve (which is a line) once.

The GCF is the largest number that can go into both the terms. Since "y" isn't in both terms, it can't include y. x, however, is, so we know our GCF has x in it. What's the largest whole number that can go into 32 and 18? 2. Your GCF is <span>2x.
