so
[tex]-12-4x+ax+b[/tex]
equate Gregory's expression to Felicia's expression
[tex]-12-4x+ax+b=-5x-10[/tex]
so
[tex]-12+b=-10[/tex] ----->[tex]b=2[/tex]
[tex]-4x+ax=-5x[/tex] ------> [tex]a=-1[/tex]
so
Gregory's expression is
[tex]-12-4x+2-x[/tex]
therefore
The missing terms are 2 and -x
To ride your favorite roller coaster, you must be at least five feet tall but
less than seven feet tall. Let h represent any height that can ride the roller
coaster.
Answer:
5 ≤ h<7
Step-by-step explanation:
the rider has to be more than at least 5 feet tall, so h is greater than or equal to 5 (5 ≤ h), but they have to be less than 7 feet tall (h<7) so, therefore, we get 5 ≤ h<7

The volume of the smaller room is B. 768 cubic feet.
Step-by-step explanation:
Step 1:
The entire length for both rooms is 20 feet. As the large room has a length of 12 feet, the length of the smaller room is [tex]20-12=[/tex] 18 feet long.
The width of the prism is 12 feet and a height of 8 feet.
The volume of a rectangular prism is determined by multiplying its length, its width, and its height.
The small room's length = 8 feet,
The small room's width = 12 feet, and
The small room's height = 8 feet.
Step 2:
The volume of a rectangular prism [tex]= (l)(w)(h).[/tex]
The volume of the smaller room [tex]= (8)(12)(8)= 768.[/tex]
So the volume of the smaller room is 768 cubic feet which is option B.
the length of a rectangle is four feet longer than the width. the area is 21. find the dimension
The dimensions of the rectangle are: Width = 3 feet, Length = 7 feet.
The formula for Area of rectangle
Area = length x width
Given:
Area of rectangle = 21 square feet.
Let the width of the rectangle is w feet.
According to the given information, the length of the rectangle is four feet longer than the width,
So, length = w + 4 feet.
So, Area of rectangle = length x width
21 = w (w+4)
[tex]\[21 = w^2 + 4w\][/tex]
[tex]\[w^2 + 4w - 21 = 0\][/tex]
Solve this quadratic equation, set it equal to zero:
w² + 7w -3w -21 =0
w(w+7)-3 (w+7)= 0
(w+7)(w-3) =0
Setting each factor equal to zero:
w+ 7 =0
w= -7
or, w - 3 =0
w = 3
So, the length of rectangle is
= 3+ 4
= 7 feet

Generally, horses are faster than donkeys. A horse can reach speeds of 55 mph (or approximately 88.50 kph). Most donkeys top out at 30 mph over short distances. What is the top speed of most donkeys in kph? Round your answer to two decimal places.
Answer:
48.30 kph
Step-by-step explanation:
55mph - 88.50kph
1mph - 1.61 kph
30 mph - 48.30 kph
Horses can reach speeds of 55 mph (approximately 88.50 kph), while most donkeys top out at 30 mph over short distances.
A conversion factor is a number that is used to multiply or divide one set of units into another. The acceptable factor to an equivalent value must be utilized when a conversion is crucial.
Given that,
Horses can reach speeds of 55 mph (approximately 88.50 kph).
Most donkeys have a top speed of 30 mph over short distances.
Here the top speed of most donkeys is asked.
To convert miles per hour (mph) to kilometers per hour (kph),
Use the conversion factor of 1.60934.
Calculate the top speed of most donkeys in kph:
Given: Top speed of most donkeys = 30 mph
Conversion: 30 x 1.60934
≈ 48.28 kph
Hence, the top speed of most donkeys, rounded to two decimal places, is approximately 48.28 kph.

what is 1735/1000 written as a decimal?
Answer:
[tex]\frac{1735}{1000}[/tex] as a decimal is 1.735.
Step-by-step explanation:
To convert a fraction into a decimal, you first have to put the fraction into simplest form.
1. Simplest form
[tex]\frac{1735}{1000} = \frac{347}{200}\\\[/tex]
To do this you must find a number you can equally divide both numbers by.
That number in this situation, 5.
[tex]1000/5= 200\\1735/5= 347\\1735:1000 = 347:200\\\frac{1735}{1000} =\frac{347}{200}[/tex]
Now you must make this simplest formed fraction into a mixed number.
2. Simplest form into Mixed number
[tex]\frac{347}{200}= 1\frac{147}{200}[/tex]
To do this you see how many times the denominator, the bottom number of the fraction, goes into the numerator, the upper part of the fraction.
Since 200 x 2 = 400 and since 400 > 347 this means...
200 goes into 347, once.
Finally, subtract and divide.
Remember put the whole number in front of the mixed number, before the decimal
3. Subtract, divide, decimalize
[tex]147/200= 0.735\\\\1\frac{147}{200}= 1.735[/tex]

What is the remainder when x^{6}-4x^4+4x^2-10 is divided by x+3?
Answer:
431
Step-by-step explanation:
Let
[tex]p(x) = {x}^{6} - 4 {x}^{4} + 4 {x}^{2} - 10[/tex]
We want to find the remainder when this polynomial is divided by x+3.
We use the remainder theorem.
Which says that, when p(x) is divided by x-a, the remainder is p(a)=R.
Therefore the remainder when p(x) is divided by x+3 is p(-3).
[tex]p( - 3) = {( - 3)}^{6} - 4 { (- 3)}^{4} + 4 {( - 3)}^{2} - 10[/tex]
We evaluate:
[tex]p( - 3) = 729 - 4 (81)+ 4 {( 9)} - 10[/tex]
We multiply to get;
[tex]p( - 3) = 729 - 324+ 36- 10[/tex]
We simplify to get:
[tex]p( - 3) =431[/tex]
Therefore the remainder is 431

O The answer will be less than the ketchup-covered number.
O The answer will be a fraction.
O The answer will be greater than the ketchup-covered number.
b.Explain your answer. How do you know the statement you chose is true?
Final answer:
Maddie should be able to tell for sure that the answer will be greater than the ketchup-covered number.
Explanation:
Based on the information provided, Maddie should be able to tell for sure that the answer will be greater than the ketchup-covered number. We can make this determination by comparing the known quantity, which is '3', with the fact that the obscured number is greater than zero. As long as the missing number is positive, any amount added to '3' would result in a sum that is larger than '3'.
If the hidden number is greater than zero and we add it to '3', the result must logically be greater than '3'. This concept is grounded in the basic principles of arithmetic, where adding a positive number to another number increases the total. Therefore, regardless of what the ketchup-covered number is, provided it is more than zero, the sum will indeed be larger than the visible number '3'.

A system of equations is shown.
x + y = 7
2x – y = – 1
What is the solution to the system of equations?
Final answer:
To solve the system of equations (x + y = 7 and 2x - y = -1), use the addition method to find that the solution is x = 2 and y = 5.
Explanation:
The question asks for the solution to the following system of equations:
x + y = 7
2x – y = – 1
To solve this system, we can use the method of addition (also known as elimination) to eliminate one of the variables. Here's how:
Add the two equations directly to eliminate variable y:
(x + y) + (2x - y) = 7 – 1
3x = 6
Therefore, x = 2.
Substitute the value of x into one of the original equations to find y:
2 + y = 7
Therefore, y = 5.
So, the solution to the system of equations is x = 2 and y = 5.
The solution to the system of equations is [tex]x = 2[/tex] and [tex]y = 5[/tex].
To solve the system of equations [tex]x + y = 7[/tex] and [tex]2x - y = -1[/tex], we can use a method called substitution or elimination. Let's use substitution for this case.
Start with the first equation:
[tex]x + y = 7[/tex]
Solve this equation for one of the variables, say [tex]y[/tex]:
[tex]y = 7 - x[/tex]
Substitute [tex]y = 7 - x[/tex] into the second equation:
[tex]2x - (7 - x) = -1[/tex]
Simplify and solve for [tex]x[/tex]:
[tex]2x - 7 + x = -1[/tex]
[tex]3x - 7 = -1[/tex]
[tex]3x = 6[/tex]
[tex]x = 2[/tex]
Substitute [tex]x = 2[/tex] back into the expression for [tex]y[/tex]:
[tex]y = 7 - 2[/tex]
[tex]y = 5[/tex]
This means that the point [tex](2, 5)[/tex] is where the two lines represented by these equations intersect. Therefore, the solution is [tex](2, 5)[/tex].
