calculate the rate of change <br> -24 ,60) ,( -34, 50<br> please help
VLD [36.1K]

Step-by-step explanation:

the rate of change is the slope of the line connecting both points.

the slope is the ratio y/x indicating how many units y changes, when x changes a certain amount of units when going from one point to another.

so, here

x changes by -10 units (from -24 to -34)

y changes by -10 units (from 60 to 50).

the slope or rate of change is -10/-10 = 1/1 = 1

2 less then 3 times a number is 9
Masteriza [31]

\huge\boxed{\text{As an expression:}\ 3x-2=9}

\huge\boxed{\text{Solved for x:}\ x=\frac{11}{3}}

Let's start with "3 times a number". We will use x to represent the number. 3x

"2 less than" is next. -2

Finally, "is 9". =9

Put it all together to get an expression. \boxed{3x-2=9}

Now, let's solve for the unknown number.

Add 2 on both sides of the equation. 3x=11

Divide both sides of the equation by 3 to isolate x. x=\boxed{\frac{11}{3}}

Find the slope of the line containing the points (2,-5) and (-4,9)
eimsori [14]

Answer:

The slope would be -2  1/3 or -2.3 repeating

Step-by-step explanation:

The first point would be (-4, 9). The next point is (2, -5). We can tell that the slope will be negative, because the x values increased by 6, but the y values decreased by 4.

The slope would be -2  1/3 or -2.3 repeating

I Hope That This Helps! :)
