Answer:
domain (-∞, ∞)
range [-3,∞)
Step-by-step explanation:
domain is the x value and range is the y value. Since its an absolute value the y value rises from both sides of the x value in a 45° angle.

It takes a groundskeeper 35 minutes to prepare a Little League baseball field for a game. It takes his assistant 45 minutes to prepare the same field. How long will it take if they work together to prepare the field?
a) It takes a groundskeeper 45 minutes to prepare a softball field for a game. It takes his assistant 50 minutes to prepare the same field. How long will it take if they work together to prepare the field?
G does 1/45 job per minute
A does 1/50 job per minute
Together, they do 1/45 + 1/50 = 19/450 jobs/minute
--> 450/19 minutes to do the job
You can use a shortcut, product/sum
50*45/(50+45) = 2250/95
= 450/19

b) It takes the owner/operator of a dog kennel 7 hours to clean all of the cages. It takes his assistant 4 hour(s) more than that to clean the same cages. How long will it take if they work together?
This is 7 and 11 hours.
7*11/(7+11) = 77/18 hours
= ~ 4.28 hours

On a coordinate grid, point T is at (2,-4) and point Sis at (2,6). The distance (in units) between points T and Sis
numbers, such as 2.) (5 points)
(Input only whole
Answer:
The distance 'd' between T and S:
[tex]d=10[/tex]Step-by-step explanation:
As the point 'T' is located at (2, -4)
So, the point 'T' has the coordinates (2, -4)And the point 'S' is located at (2, 6)
So, the point 'T' has the coordinates (2, 6)The distance 'd' between T and S can be computed using the formula:
[tex]d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]
[tex]=\sqrt{\left(2-2\right)^2+\left(6-\left(-4\right)\right)^2}[/tex]
[tex]=\sqrt{\left(2-2\right)^2+\left(6+4\right)^2}[/tex]
[tex]=\sqrt{0+10^2}[/tex]
[tex]=\sqrt{10^2}[/tex]
[tex]d=10[/tex]
Therefore, the distance 'd' between T and S:

How many yards long is a piece of fabric witha width of 5/8 yrd nd a area of 2 3/4 square yards?
Answer:
D. [tex] 4\frac{2}{5} [/tex]
Step-by-step explanation:
Area of fabrics = 2¾ square yards
Width of fabrics = ⅝ yard
Length of fabrics = x
Area = length * width
Therefore:
2¾ = ⅝*x
Change the mixed fraction to improper fraction
[tex] \frac{11}{4} = \frac{5x}{8} [/tex]
Cross multiply
[tex] 4*5x = 11*8 [/tex]
[tex] 20x = 88 [/tex]
Divide both sides by 20
[tex] \frac{20x}{20} = \frac{88}{20} [/tex]
[tex] x = \frac{22}{5} [/tex]
[tex] x = 4\frac{2}{5} [/tex]
[tex] length = 4\frac{2}{5} [/tex]

Veronica observes how the force of friction causes an object to slow down. She writes the following observation: When an object moves across a smooth surface, there is less friction created than when an object moves across a rough surface. When the object stops moving, friction is created. Which statement corrects the error(s) in Veronica's observations?
A) It is not smooth or rough surfaces that affects friction. It is the size of the push.
B) When an object moves across a rough surface, there is no friction.
C) When an object moves across a smooth surface, the friction increases.
D) When an object stops moving, there is no friction.

Can x-2 be simplified more? Why?
Answer:
No:
Step-by-step explanation:
No, there is no way to further simplify this equation, unless there is a value for x.
Answer:
No. x-2 can't.
Step-by-step explanation:
Its the same reason why you can't simplify 1+1. You could add them together, but in a case like this, where one number is unknown you can't. The number is already to its simplifiest form.

Equation:
Solution:
Answer:
11
Step-by-step explanation:
Equation: 8x - 12 = 76
Add 12 to both sides
8x = 88
Divide both sides by 8
x = 11

Triangle ABC IS an isosceles triangle AB=BC m
Answer:
The measure of angle A is 73°
Step-by-step explanation:
Isosceles Triangles
An isosceles triangle is a triangle with exactly two congruent sides. The angles the congruent sides form with the third side are also equal.
The triangle ABC is isosceles and AB congruent with BC. The angle at B measures 34°.
The other two angles are congruent, i.e. their measures are the same. Since the internal angles of a triangle sum 180°:
[tex]2*m\angle A=180^\circ - 34^\circ =146^\circ[/tex]
Thus:
[tex]m\angle A=146^\circ /2=73^\circ[/tex]
The measure of angle A is 73°
Brian has 17 fewer marbles
than Kyle. Brian has
21 marbles. How many
marbles does Kyle have?
Answer:
the answer to your question is 38.
There are 38 marbles does Kyle have.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Brian has 17 fewer marbles than Kyle.
And, Brian has 21 marbles.
Now,
Let number of marbles Kyle have = x
Then, Number of marbles Brian have = x - 17
But, Brian has 21 marbles.
So, We get;
x - 17 = 21
x = 21 + 17
x = 38
Thus, There are 38 marbles does Kyle have.

A girl has $2.85 in nickels and quarters. How many of each type of coin does she have if there
are 21 coins in all? *
(4 Points)
n + 9 = 21 and .05n + .25q = 2.85
n = 12,9 = 9
n = 5,9 = 26
n = 31, 9 = 22
n = 5,9 = 7
Answer:
n = 12, q = 9
Step-by-step explanation:
The simultaneous equation that represents the expression is;
n + q = 21 .......... 1
0.05n + 0.25q = 2.85 ........ 2
Multiply equation 2 by 100 to have;
5n + 25q = 285
n + 5q = 57
____________________________________
n + 5q = 57
n + q = 21
Substract the resulting equations
5q-q = 57-21
4q = 36
q = 36/4
q = 9
Substitute q = 9 into eqn 1;
From 1; n+q = 21
n = 21-q
n = 21-9
n = 12
Hence she has 12 nickels and 9 quarters
A water tank leaked 14 gallons of water over eight hours at a constant rate what was the change in the amount of water in gallons in a tank each hour
Answer: the answer would be 1.75 gallons/hour
Step-by-step explanation: if you take the 14 gallons divided by the eight hours, you get 1.75
Answer:
7/4 gallons per hour
Step-by-step explanation:
We have to divide the amount of water lost by the lapse of time. So we get
14/8= 7/4
