Answer:

THis is a function.

Step-by-step explanation:

If you draw a straight line vertically, it won't intersect more than one point of the line. This is called the vertical line test, and if the line you drew passes the line on the graph more than once, its not a function.

Yw, brainliest, and don't plagiarize, they'll catch you.

It’s a function because it doesn’t go over the vertical line test

Find the X of 12X-2+(-102)=180

loris [4]

Answer:

X = $\frac{284}{12}$ = $\frac{71}{3}$

Step-by-step explanation:

12X-2+(-102)=180

First let's gather all the terms on one side and the integers on the other.

12X = 180 + 102 + 2

12X = 284

Solve for X by dividing by 12.

12X/12 = 284/12

X = $\frac{284}{12}$

Which can be simplified:

$\frac{71}{3}$ = 23.66666667

Tyree is determining the distance of a segment whose endpoints are A(–4, –2) and B(–7, –7).

PilotLPTM [1.2K]

Answer:

Tyree’s solution is inaccurate. In step 1, he substituted incorrectly.

Step-by-step explanation:

to find the distance between two point A(-4, -2) and B(-7, -7) we use the following distance formula

$d=\sqrt{(x_{2} -x_{1})^2+(y_{2}-y_{1} )^2 \\\\$

x1=-4, x2=-7

y1=-2, y2=-7

so,

$d=\sqrt{(-7-(-4))^2+(-7-(-2) )^2\\}\\\\d=\sqrt{(-7+4)^2+(-7+2)^2 }\\\\d=\sqrt{(-3)^2+(-5)^2 }\\\\\\\\d=\sqrt{9+25}\\ \\d=\sqrt{34}$

9 was subtracted from a certain number and the result was divided by 4. If the final answer is 5, what was the original number?

Ierofanga [76]

Answer:

let the number be X

Step-by-step explanation:

(x - 9)/4 = 5

or. x - 9 = 5 × 4

or. x = 20 + 9

x = 29
