Answer:

y= -0.75x+5.75

Step-by-step explanation:

so, if y=mx+c

the gradient is m, which is equal to (y1-y2)/(x1-x2), (2--4)/(-5-3) = 6/-8=-0.75

so y= -0.75x+c

substitute y and x values

2(y)= -0.75(m)*-5(x)+c

2=-0.75*5+c

2= -3.75+c

5.75=c

so in the end, y= -0.75x+5.75

Answer:

All real numbers

Step-by-step explanation:

We can start out by knowing that the domain of a graph is, the side, to side from the x axis directions.

We can see that the line continues of the graph shown, meaning it is infinite. Meaning the answer is the domain is all real numbers.

We can double check by seeing that the other options don't work or aren't enough:

$x\geq 2\\and\\x\leq 2\\and\\x\geq -4$

The first wouldn't work becuase, yes that is part of the answer, but not the whole answer. The same goes for the others as well, they are on the line and are correct, but the best, and full answer is "All real numbers"

Jaun's age, x, is 4 times his age 15 years ago

KIM [24]

The expression of the mathematical statement given as "Jaun's age, x, is 4 times his age 15 years ago" is x = 4 * (x - 15)

<h3>How to rewrite the statement as an expression?</h3>

The mathematical statement is given as

Jaun's age, x, is 4 times his age 15 years ago

From the statement, we have:

x represent Juan's current age

This means that his age 15 years ago is

15 years ago = x - 15

4 times his age 15 years ago is

4 * 15 years ago = 4 * (x - 15)

The above equation is equivalent to his current age

So, we have

x = 4 * (x - 15)

Hence, the expression of the mathematical statement given as "Jaun's age, x, is 4 times his age 15 years ago" is x = 4 * (x - 15)
