what is the absolute value of -2 and 2
Answer:
2
Step-by-step explanation:
since absolute value is the length that a number is away from 0, an absolute value can never be negative. 2 and -2 are both 2 spots away from 0.
Are these congruent by SSS, SAS, AAS, ASA?
Answer:
SAS (Side Angle Side)
Step-by-step explanation:
It is SAS because both triangles are congruent due to 2 congruent sides and one congruent angle, thus being SAS.
what is the rate of change in y= 2x+3
Answer:
The Answer is 2
EXPLANATION:
y(x)=2x+3
y(x+Δx)=2(x+Δx)+3
=2x+2Δx+3
Δy=y(x+Δx)−y(x)
=(2x+2Δx+3)−(2x+3)
=2Δx
⇒Δy=2Δx, Δy/Δx =2
The rate of change in the equation of a line in slope-intercept form
y = 2x + 3 is 2.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
Given, An equation of a line y = 2x + 3.
This is in slope-intercept y = mx + b, where 'm' is the slope.
Therefore, The rate of change in y = 2x + 3 is 2.

Leroy wants to buy a new racing bicycle that costs $168. To earn money, he can either do yardwork for his grandmother or babysit his brother and sister. He earns $24 for 3 hours of yardwork and he earns $48 for 4 hours of babysitting. How much longer will it take him to earn the money if he only does yardwork for his grandmother?
______ hours
PLEASE HELP DUE AT 11:59 PLEASE
Answer:
7 hours
Step-by-step explanation:
This is because 24/3=8
48/4=12
168/12=14
168/8=21
21-14=7
It take him 7 hours to earn the money if he only does yardwork for his grandmother.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
Given that Leroy wants to buy a new racing bicycle that costs $168. He earns $24 for 3 hours of yardwork and he earns $48 for 4 hours of babysitting.
We need to find the time take to earn the money if he only does yardwork for his grandmother.
Thus, $24 for 3 hours of yardwork
24/3=8
Again, $48 for 4 hours of babysitting.
48/4=12
Now, 168/12=14
168/8=21
The time difference is;
21-14=7

3x-y=5
write each equation in slope-intercept form
Answer:
y = 3x - 5
Step-by-step explanation:
3x-y=5
-3x -3x
-y= -3x + 5
divide each number by -1
-y/-1 = y
-3x/-1 = 3x
5/-1 = -5
The equation 3x - y = 5 can be converted to slope-intercept form as follows: y = 3x - 5
Given is an equation 3x - y = 5, we need to convert it in slope-intercept form.
To convert the equation 3x - y = 5 into slope-intercept form (y = mx + b), where "m" represents the slope and "b" represents the y-intercept, we need to isolate the variable "y" on one side of the equation.
Let's rearrange the given equation step by step:
Starting with 3x - y = 5, we can begin by moving the term involving "x" to the other side:
3x - y + y = 5 + y
Simplifying:
3x = y + 5
Now, let's isolate "y" by subtracting "y" from both sides:
3x - y = y + 5 - y
Simplifying:
3x - y = 5
To eliminate the "y" term on the left side, we can add "y" to both sides:
3x - y + y = 5 + y
Simplifying:
3x = 5 + y
Next, let's rearrange the equation to have "y" on the right side:
3x = y + 5
We can write this equation as:
y = 3x - 5
Now the equation is in slope-intercept form (y = mx + b), where the slope "m" is 3, and the y-intercept "b" is -5.

how can I find the slope to this I need help
Answer:
Your slope is -1
Step-by-step explanation:
Find the change in x and the change in y and put it in change in y over change in x.
Δx = -1 - -2 = 1
Δy = -1 - 0 = -1
Slope = rise over run = Change in y over change in x = Δy/Δx = -1/1
Therefore the slope is -1/1 which is written as just -1

So u look in the answers, you can already take two answers out which are the 2 and the 3 bcs they are open circle. Then x ≥ 98.6, then x is bigger than the 98.6 so the arrow would go to the right. And the answer would be first one
(How to do that in an easier way, Look at this ≥, the pointy side is aiming in the right so the arrow will go always to the right, THIS ONLY WORKS WHEN THE LETTER IS IN THE LEFT {EX. y ≤ 19, the arrow will be pointing in the left.)

Lili runs a small day care business, caring for 3 children.
• She earns $150 during regular work hours.
• She charges $0.50 for each minute parents are late.
The situation is represented by the equation below, where t is the total
dollar amount Lili earns each day and m is the total number of minutes
parents are late.
t=150 +0.5m
Which of the following solutions shows an amount of money Lili can
reasonably expect to earn each day?
Answer:
$150
Step-by-step explanation:
[tex]t=150 + 0.5m\\t=150+0.5*0\\t=150[/tex]
This is as we don't know how often the parents are late, nor if they are late. So we assume that the parents are never late.

Mohammed built a building that can carry up to 5 tons. If each person weighs about 150 pounds, how many people can fit onto the building that Mohammed built?
Answer:
Step-by-step explanation:
To start solving this problem, you need to figure out how many Pounds( I'll use lbs.) = 5 Tons( I'll use T).
2,000 lbs. = 1 T.
X 5 X 5
10,000 lbs. = 5 T.
Now we divide. That just means that if we know that 1 person( I'll use P) = 150, we just divide 5 T( 10,000 lbs.) by 150 lbs.
10,000/150=66.6666666667

Michelle simplified an expression for the perimeter of the rectangle below and got 5/6x + 35. Explain her error, and include the correct expression for the perimeter.
The width is 5/6x+23 and the Height is 12.
Answer:
Michelle didn't double the height and width for the perimeter and the correct expression is:
[tex]\frac{5}{3}x+70[/tex]
Step-by-step explanation:
Given
Length = l = 5/6x+23
Width = w = 12
The perimeter of a rectangle is given by:
[tex]P = 2(l+w)[/tex]
Putting the values, we get
[tex]P = 2\{(\frac{5}{6}x+23)+12\}\\\\P = 2(\frac{5}{6}x+23+12}\\P =2(\frac{5}{6}x+35)\\P = 2*\frac{5}{6} + 2* 35\\P =\frac{5}{3}x+70[/tex]
The length and width had to be doubled for the perimeter which Michelle didn't.
Hence,
Michelle didn't double the height and width for the perimeter and the correct expression is:
[tex]\frac{5}{3}x+70[/tex]
