The rate of change is x2. So, since it's forty, it became 80 because 40x2=80!
Good luck for a good grade!

-2 (h - 5) < -12 Please some help me I don’t understand :(

Marysya12 [62]

Answer:

$h>11$

Step-by-step explanation:

We have the inequality:

$-2(h-5)$

Solve. Divide both sides by -2. Since we are dividing by a negative, we must flip the inequality sign. Thus:

$h-5>6$

Add 5 to both sides:

$h>11$

Therefore, our solution is all numbers greater than 11 .

This means that if we substitute any number greater than 11 into our original inequality, the inequality will be true.

I NEED HELP

creativ13 [48]

Answer:

1). (x - 4 = 13)

2). (r + 17 = 51)

3). (7/9x =28)

4). (2/3x = 2)

5). { 3(x-2) = -9 }

6). (x -1.75 = 8.85)

7). Natalie buys organic almonds priced at $77 from the grocery store. How much did

she pay the cashier, if she received $23 in change?

Step-by-step explanation:

1. add 4 on both sides and it will be x=17

2. subtract 17 on both sides and it will be x= 34

3. multiply 9/7 on both sides and it will be x= 257/7 then you divide 257 by 7 then the final answer will be x= 36

4. multiply 3/2 on both sides and it will be x=6/2 then you divide 6 from 2 and the finial answer will be x= 3

5. you will distribute 3 into x and 2 and you will be 3x-6=-9 then you will add 6 on both sides so you will get 3x=3 and then divide 3 on both side so you will get x=1

6. add 1.75 on both sides so x= 10.6

7. the equation will be 23 +x = 77 so first you will subtract 23 on both sides and x will equal 54 so Natalie paid $54

Determine if the statement is always, sometimes or never true.

Romashka-Z-Leto [24]

Let

x--------> the measure of the adjacent interior angle

y--------> the measure of an exterior angle at the vertex of a polygon

we know that

The measure of the adjacent interior angle and the measure of an exterior angle at the vertex of a polygon are supplementary angles

$x+y=180$ °

Examples

case 1)

In a square

$x=90$ °

$y=180-90=90$ °

$x=y$

In this case

The measure of an exterior angle at the vertex of a polygon equals the measure of the adjacent interior angle

case 2)

an equilateral triangle

$x=60$ °

$y=180-60=120$ °

$x\neq y$

In this case

The measure of an exterior angle at the vertex of a polygon is not equals the measure of the adjacent interior angle

therefore

the answer is

sometimes
