Answer:

first part: A. x^2+9x=36 and C. (x+9)(x)=36

second part: Width = 3 inches, Length = 12 inches

Step-by-step explanation:

"more than" implies addition, so you know you'll have 9+x in the equation you also know that you have to have the equation =36

also note (9+x is the length)

the equation for area of a rectangle is A=LW

so lets plug in what we do know

A = L W

36=(9+x)W

For the first part of the equation you're answer will be:

(x+9)(x)=36 AND x^2+9x (the reason for the second answer i listed is because when you multiple (x+9)(x) you get x^2+9x

when you solve for x it equals 3,

so the width (x) = 3 inches

and the Length (9+3) =12 inches

Answer:

[tex](\frac{1}{3}x - 3,-\frac{1}{3}y+2)[/tex]

Both triangles will be similar

Step-by-step explanation:

See comment for complete question.

Given

Let the coordinates of the triangle be T(x,y)

First transformation: Dilation by 1/3

The new points will be:

[tex]T' = \frac{1}{3}(x,y)[/tex]

[tex]T' = (\frac{1}{3}x,\frac{1}{3}y)[/tex]

Second: Reflection over the x-axis

When a point (x,y) is reflected over the x-axis, the new point is (x,-y).

So, we have:

[tex]T'' = (\frac{1}{3}x,-\frac{1}{3}y)[/tex]

Third: Translation 3 units left and 2 units up.

When a point (x,y) is translated b units left and h units up, the new point is (x - b,y+h).

In this case:

[tex]b = 3[/tex] and [tex]h = 2[/tex]

So, we have:

[tex]T''' = (\frac{1}{3}x - 3,-\frac{1}{3}y+2)[/tex]

Hence, the coordinate of the new triangle will be: [tex](\frac{1}{3}x - 3,-\frac{1}{3}y+2)[/tex]

Additionally, both triangles will be similar because all the transformation done are rigid transformations i.e. Dilation, Reflection and Translation

Answer:

the car travels faster

Step-by-step explanation:

Since the motorcycle has traveled 300 feet, and the car has traveled 600 feet, we will divide 600 by 2

600 divided by 2 = 300

Hank would have traveled 300 feet in 10 seconds

Andy traveled 300 feet at 12 seconds

Therefore Hanks car travels faster

Answer:

The car travels faster

Step-by-step explanation:

600 ft per 20 secs

How many feet in one sec?

600/20 = 30

Hank's car = 30 feet per second

300 feet in 12 sec

How many feet in one sec?

300/12 = 25

Andy's motorcycle = 25 feet per second

It should be noted that since the rabbit from the previous problem started at 10, it would be at 17 units on the number line after the same three jumps.

A number line is a type of graph with a graduated straight line which comprises both positive and negative numerical values. From the previous problem, the total distance covered by the rabbit is given by:

Total distance = 4 units + 2 units + 1 unit

Total distance = 7 units.

Since the second point is at 10 units and the open circle arrow points to the right of the number line, the rabbit would cover 7 more distance from this point:

Total distance = 10 units + 7 units

Total distance = 17 units.

Answer:

3 x -3y = -9y

3 x -1 = -3

The factored expression is 3(-3y - 1)

Step-by-step explanation:

All you have to do is -9y / 3 = -3y and -3 / 3 = -1, then put those numbers in parentheses. All of that is multiplied by 3.

The reason is because if you distributed the 3 it would become:

3 * -3y + 3 * -1 = -9y - 3

Answer:

(i) 1/2

(ii) 3/20

Step-by-step explanation:

(i) given total number of white counters = 10

total outcomes = 20 (3+10+5+2)

so it's 10/20

by simplifying it we get 1/2

(ii) given total number of red counters = 3

so it's 3/20

Given :

A bakery sells mocha cupcakes and vanilla cupcakes.

It sold 391 mocha cupcakes in a day.

15% of the cupcakes sold that day were vanilla.

To Find :

How many total cupcakes did the bakery sell that day.

Solution :

Let, total number of cupcakes bakery sell that day is x.

So, x - 0.15x = 391

0.85x = 391

x = 460

Therefore, total number of cupcakes bakery sell that day is 460 .

Answer: C. Distribute 3/4 over (x-8)

Step-by-step explanation:

To solve any(technically most, but still...) algebraic equation you must isolate the variable.  In this case, the first step would either be to divide both sides of the equation by 3/4, or distribute 3/4 to x and -8, as you cannot modify the contents of the parenthesis without removing the 3/4.

#5- 7.8 hours  #6- $5.25

Step-by-step explanation

Question #5- 7.8 hours      

First we have to find the speed. If the speed was constant we should be able to divide the miles by the time to find the speed. So 239.82 divided by 4.2. This would leave us with a speed of 57.1 mph. So to finish the question, we have to take  what we know and divided it by the speed. If he drives 445.38 miles at the same speed of 57.1 mph it would take him 7.8 hours. I got this answer by dividing the miles by the speed. 445.38 divided by 57.1. Which got us our time, 7.8 hours.

Question #6- $5.25

Okay so we know that the chips cost .75 cents a bag, and he got two bags. So if we take .75 and multiply it by two we get 1.50. So the chips alone cost $1.50. We can take the price of the chips and subtract it from the total price. 22.50-1.50. 21. Now we have just the prices of the sandwiches. If we take the total price of the sandwiches and divide it by the number of sandwiches bought, we get $5.25. So each sandwich cost $5.25 each.

-------------------------

h < 3

Step-by-step explanation:

5h – 4 > 6

add 4 both sides

5h > 10

divide 5 both sides

h > 2

-------------------------

7h + 11 < 32

subtract 11 both sides

7h < 21

divide 7 both sides

h < 3

x=-3

x=-11

because

x(x+14)=-33

so if x = -11 it will be 3*-11

and if x= -3 it will be -3*11

Answer:

x = -3, -11

Step-by-step explanation:

First, factor

Get all the terms on one side by adding 33 to both sides:

[tex]x^2 + 14x + 33 = 0[/tex]

now, you want to find two numbers that add up to 14 and multiply to 33.

those numbers would be 3 and 11.

so you can then make it:

[tex](x + 3)(x+11)=0[/tex]

you know that either x + 3 or x + 11 = 0,

so you can say:

x + 3 = 0

x = -3

ork

x + 11 = 0

x = -11

so x = -3, -11.
