The mathematical descriptions are matched to correct algebraic expressions as below.
What are Expressions?Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.
The absolute value of twice a number increased by 11.
Let the number be x.
Twice the number is 2x and then increased to 11 means 2x + 11.
Absolute value of this is |2x + 11|.
The square root of the difference of the square of a number and 11.
Square of a number means x².
Difference of the square of a number and 11 means x² -11.
Square root of this is [tex]\sqrt{x^2-11}[/tex].
The quotient of two times a number and -11.
Quotient means the operation is division.
Two times a number means 2x.
The quotient of this and 11 is - 2x/11.
The sum of the square root of two times a number and 11.
Square root of two times a number is [tex]\sqrt{2x}[/tex]
Sum of this and 11 is [tex]\sqrt{2x}[/tex] + 11.
Hence the mathematical descriptions are matched to corresponding expressions.

Which value of h makes
8+h/10=1 a true statement?
Answer: 2
Step-by-step explanation:
Anything divided by itself equals one. So, 8 + 2 = 10 and 10/10 = 1
Answer:
h = -70
Step-by-step explanation:
8+h/10=1
Subtract 8 from each side
8-8+h/10=1-8
h/10 = -7
Multiply each side by 10
h/10 * 10 = -7 * 10
h = -70
f(x)=-4x^2-x-3 Find f(1)
Answer:
f(1)=-8
Step-by-step explanation:
Value of a function
Given a function expressed as y=f(x), where x is the independent variable, and y is the dependent variable, we can give x any desired value in the domain of f.
We are given the function
[tex]f(x)=-4x^2-x-3[/tex]
To find f(1), we replace the variable x for the value 1, and we get:
[tex]f(1)=-4(1)^2-(1)-3[/tex]
[tex]f(1)=-4*1-1-3[/tex]
[tex]f(1)=-4-1-3=-8[/tex]
Thus, f(1)=-8

Given: Lines p and q are parallel and r is a transversal. Prove: ∠2 ≅ ∠7. Which statements could complete the proof?
Answer:
Angle 2 is congruent to angle 3
Angle 3 is congruent to angle 7
If lines p and q are parallel and r is a transversal. so, ∠2 is congruent to angle ∠3 and ∠3 is congruent to angle ∠7.
How to Identify Transverse and Parallel Lines?From the transverse and parallel line theorem of geometry, we know that:
If two parallel lines are cut by a transversal, then corresponding angles are congruent.
Two lines cut by a transversal are parallel IF AND ONLY IF corresponding angles are congruent.
Lines p and q are parallel and r is a transversal.
Angle 2 is congruent to angle 3
Angle 3 is congruent to angle 7.

Dana is filling a 1.5 gallon watering can at a rate of 0.75 gallon per minute. What is the domain of the function that represents the volume of water in the can after x minutes?
Answer:
The domain of the function is [tex]Dom \{y\} = [0\,min, 2\,min][/tex].
Step-by-step explanation:
We understand that the watering can is filled at a constant rate, that is:
[tex]y =k\cdot x[/tex]
Where:
[tex]x[/tex] - Filling time, measured in minutes.
[tex]y[/tex] - Watering can volume occupied by water, measured in gallons.
[tex]k[/tex] - Filling rate, measured in gallons per minute.
If we know that [tex]k = 0.75\,\frac{gal}{min}[/tex] and [tex]y = 1.5\,gal[/tex], the final filling time is:
[tex]x = \frac{y}{k}[/tex]
[tex]x = \frac{1.5\,gal}{0.75\,\frac{gal}{min} }[/tex]
[tex]x = 2\,min[/tex]
The domain of the function corresponds to the set of real numbers between zero and final filling time. That is to say:
[tex]Dom \{y\} = [0\,min, 2\,min][/tex]

Alan starts walking from a point O, at a constant speed of 4 m s−1, along a horizontal path. Ben walks along the same path, also starting from O. Ben starts from rest 5 s after Alan and accelerates at 1.2 m s−2 for 5 s. Ben then continues to walk at a constant speed until he is at the same point, P, as Alan.
(i) Find how far Ben has travelled when he has been walking for 5 s and find his speed at this instant. [2]
(ii) Find the distance OP. [3]
Answer:
(i) 15 m, 6 m/s
(ii) 90 m
Step-by-step explanation:
(i) For some acceleration (a) from rest, the distance covered (d) in time t is ...
d = (1/2)at^2
The distance covered by Ben in the 5 seconds he is accelerating is ...
d = (1/2)(1.2 m/s²)(5 s)² = 15 m
Of course, Ben's speed at that point is ...
s = (1.2 m/s²)(5 s) = 6 m/s
__
(ii) When Ben has been walking 5 s, Alan has been walking 10 s, so Alan has covered (10 s)(4 m/s) = 40 m. Their distance difference of 40 -15 = 25 m is being made up at the rate of their speed differences: (6 m/s) -(4 m/s) = 2 m/s.
It will take (25 m)/(2 m/s) = 12.5 s additional time for Ben to catch Alan. In the 22.5 s that Alan has been walking before they meet, he will have walked ...
(22.5 s)(4 m/s) = 90 m . . . the distance OP

What is the probability of picking a multiple of 3?
Write your answer as a fraction in simplest form.
Answer: 3/10!!
Step-by-step explanation: 3 can be divided by 3, 6, and 9. Making them multiples of 3.
The probability of picking a multiple of 3 is 3/10.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
We have,
Sample space = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
There are ten numbers.
i.e N = 10
Numbers that are multiples of 3 = {3, 6, 9}
There are three numbers.
i.e M = 3
Now,
The probability of picking a multiple of 3.
= M/N
= 3/10
Thus,
The probability of picking a multiple of 3 is 3/10.

Determine if the relation is a function. In your handwritten work, explain why or why not.
Please and Thank you!!!
Answer:
Step-by-step explanation:
Its not a function. The reason its not a function is because it doesnt pass the vertical line test. You could graph these points physically or you could think about it. The domain is the x value, while the range is the allowed y values. So by having the same x value relate to two different y values, just makes no sense. Imagine the function is x+4 and we are given in that graph that when x equals 6, the y equals 9 and 10. That isnt possible because we know the answer is 10, not 9, it cant be both.
Another way you could prove this is by graphing. If you try to take the slope in that interval where 6 coorelates to two y values. The change in y is 1, but the change in x is 0. When you divide 1/0, your calculator blows up. Try it

The measure of the line segment would be 62 units if the JL = 5x + 2 and JL = 27 + 3x - 1 from the line segment.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
It is given that:
JL = 5x + 2
From the line segment we get;
JL = 27 + 3x - 1
Now substitute the value of JL in the equation;
5x + 2 = 27 + 3x - 1
After solving;
5x - 3x = 26 - 2
2x = 24
x = 12
JL = 5x + 2
Plug x = 12
JL = 5(12) + 2
JL = 60 + 2
JL = 62 units
Thus, The measure of the line segment would be 62 units if the JL = 5x + 2 and JL = 27 + 3x - 1 from the line segment.
