Answer:

A relation is a function if x values never repeat, so every input will only have one output. If the function is graphed you can do the vertical line test, a relation passes if you can draw a vertical line anywhere on the graph and it only intersects with the relation once.

Choose Yes or No to tell whether each expression is equivalent to –43p – 25.

Rashid [163]

Answer:

–43p + (–25) is EQUIVALENT to –43p – 25.

Step-by-step explanation:

<u>The options are MISSING.</u>

The needed options are:

1. 25 – 43p

2. 25 – 43p

3. –25p –43

4. –43p + (–25)

Now, here the given expression is: –43p – 25

Taking each option and simplifying it , we get:

1. 25 – 43p

Here, the second term is NEGATIVE, but the first term (25) is POSITIVE.

⇒ 25 – 43p ≠ –43p – 25

Hence, 25 – 43p is NOT EQUIVALENT.

2. 25 – 43p

Here, the second term is NEGATIVE, but the first term (25) is POSITIVE.

⇒ 25 – 43p ≠ –43p – 25

Hence, 25 – 43p is NOT EQUIVALENT.

3. –25p –43

Here, the variable p is multiplied with (-25) and NOT (-43).

⇒ –25p –43 ≠ –43p – 25

Hence, –25p –43 is NOT EQUIVALENT.

4. –43p + (–25)

Here, both the given terms (43) and (25) are NEGATIVE.

Also, the varibale p is multiplied with (-43)

⇒ –43p + (–25) = –43p – 25

Hence, –43p + (–25) is EQUIVALENT.

Which equation represents the line that passes through points B and C on the graph? 2 4 3 B 3 4 5 ภา

777dan777 [17]

The point B has coordinates (-4,2) and C has coordinates (-2,-2). We are going to calculate the slope of the line

$m=\frac{y2-y1}{x2-x1}=\frac{-2-2}{-2-(-4)}=-2$

Then, we are going to calculate the intercept using the slope m=-2 and the point (-4,2).

y=mx+b

2 = -2*(-4)+b

Isolating b we get

2-8=b= -6

The equation would be

y=-2x-6, option A
