Hello!!! Princess Sakura here ^^

Step-by-step explanation:

The average rate of change is just like how you would find the slope so that's what I'm going to do.

[tex]m=\frac{6-0}{-2--5}[/tex]

I will use this equation to find it...

[tex]m=\frac{6-0}{-2--5}=\frac{6}{3} =2[/tex]

So the rate of change is 2.

Answer:

x = - [tex]\frac{41}{14}[/tex]

Step-by-step explanation:

Given

7(2x + 6) = 1 ← distribute parenthesis on left side

14x + 42 = 1 ( subtract 42 from both sides )

14x = - 41 ( divide both sides by 14 )

x = - [tex]\frac{41}{14}[/tex]

Answer:

2.2 ounces.

Step-by-step explanation:

Quantity of peanuts Diana bought = 16.5 ounces

Quantity used for peanut brittle = 3/5

Hence:

3/5 × 16.5

= 9.9 ounces was used for peanut brittle.

The amount left =

16.5 ounces - 9.9 ounces

= 6.6 ounces.

We are told that: the next week, she split the remaining peanuts into 3 bags of trail mix for a hike with friends.

The ounces of peanuts she put in each bag of trail mix is calculated as:

6.6 ounces ÷ 3 bags

= 2.2 ounces.

Answer:

0.9

Step-by-step explanation:

72÷8= 9

7.2÷8=0.9

if you add a decimal ur answer is going to have a decimal

in this case 7.2 the decimal is in the tenths place so the answer would be 0.9

Answer:

18

Step-by-step explanation:

For this problem, we will simply plug in the values of a and b into the respective variables in the expression 3ab to "evaluate" the expression.

a = 2; b = 3

3ab

Note, that when variables like a and b are smashed with a constant, the use of multiplication is in play.

3ab = 3 * a * b

With this in mind, let's plug in the values of a and b into the expression.

3ab

= 3 (2) (3)

= 3 (6)

= 18

Hence, 3ab evaluated when a=2 and b=3 is 18.

Cheers.

Step-by-step explanation:

The coach will most likely count this as an expense and will want to overestimate so that he is certain to have all the golf balls for his lessons. If he underestimates, he will not be able to have all his balls.

A. It is better to overestimate to make sure the coach has enough money to buy the golf balls.

Over estimating is when we set a higher amount than we need in case of price increase and the item is a must buy.

Underestimating when we set a lower amount than needed when money is of more concern and the item is not a must buy.

According to the given question At the beginning of the season, a golf coach buys 118 sleeves of golf balls. Each sleeve costs $8.

It is always better to overestimate and if some amount remains then it can be used later.

So, It is better to overestimate to make sure the coach has enough money to buy the golf balls to continue his lessons without any interruption underestimating will lead to less golf balls and interrupted golf sessions.

AB || CD and AC is oblique ;

So : Angle ( BAC ) = Angle ( DCA )

_________________________________

∆ ABC - ∆ ACD :

(1) AB = CD

(2) Angle ( BAC ) = Angle ( DCA )

(3) AC = AC

So According to (1) , (2) , (3) :

∆ ABC =~ ∆ ACD

The value of x is 4, which is determined by the quadratic equation.

The area of a rectangle is defined as the product of the length and width.

The rectangle of a rectangle = L × W

Where W is the width of the rectangle  and L is the length of the rectangle

We have been given that area of the rectangle = 36

Area of rectangle = width of the rectangle × length of the rectangle

Here the width of the rectangle = x

And length of the rectangle = x + 5

The rectangle of a rectangle = x × (x + 5)

36 = x² + 5x

x² + 5x - 36 = 0

x² + 9x - 4x - 36 = 0

(x + 9)(x - 4) = 0

x = -9 and x = 4

Take the value of x = 4 and the negative value is neglected because the dimension can't be negative.

Therefore, the value of x is 4.
