A number line going from negative 5 to positive 5. The distance from negative 3 to 3 is labeled negative 6.
Answer:
ITS A
Step-by-step explanation:
The number line that will represent the absolute value will be-
the distance from negative 3 to 0 is labeled 3.
What is absolute value of a number?The absolute value of a number is the magnitude of number. Absolute value describes the distance from zero that a number is on the number line, without considering direction.
We have a graph represents the absolute value of –3.
For a number [x], such that [x] < 0, the absolute value would be -
v[a] = -x
So, for x = -3, the absolute value would be 3.
The number line that will represent the absolute value will be -
The distance from negative 3 to 0 is labeled 3.
Therefore, the number line that will represent the absolute value will be-
the distance from negative 3 to 0 is labeled 3.

Susan is looking to hire a cleaning company to clean her house every week. One cleaning company's cost can be calculated by the expression 75 + 50x, where x is the amount of hours they spend cleaning. Another cleaning company's cost can be calculated using the expression 50 + 75x. Susan wants to know how long each company will have to clean to cost the same amount. Group of answer choices 1 hour 2 hours the will never equal the same 7.5 hours
Answer:
A. 1 hourStep-by-step explanation:
If one cleaning company's cost can be calculated by the expression 75 + 50x, where x is the amount of hours they spend cleaning and another cleaning company's cost can be calculated using the expression 50 + 75x, then to calculate how long each company will have to clean to cost the same amount, we will equate both expression of the company cost and solve for x as shown;
On equating:
75 + 50x, = 75x + 50
collect like terms'
50x-75x = 50-75
-25x = -25
divide both sides by -25
-25x/-25 = -25/-25
x = 1
hence the number of hours each company will have to clean to cost the same amount is 1 hour

Answer:
7=7
Step-by-step explanation:
Answer:
X^2+11x+28
Step-by-step explanation:
FOIL = First, Outer, Inner, Last
First: x times x= x^2
Outer: x times 7= 7x
Inner: 4 times x= 4x
Last: 4 times 7= 28
Since outer and inner are both positive you would add togther. Therefore answer is x^2+11x+28
The question just asks “Find QT” pls help
Answer:
QT = 21
Step-by-step explanation:
Because the left section is technically just a extension of the right triangle, the two triangles (PRQ and SRT) are similar, so the ratio between the sides will be similar as well.
The small triangle (SRT) has a ratio of 8/7 between its top side SR (40) and its bottom side TR (35). This means that the top and bottom side of the triangle PRQ will have the same ratio, and since we already known PR (24+40), we can write an equation to solve for QR:
[tex]\frac{SR}{TR} =\frac{PR}{QR} \\\\\\frac{40}{35}=\frac{64}{?}[/tex]
[tex]\frac{8}{7} =\frac{64}{?}[/tex]
64/8=8
This means so get our unknow length, we will need to multiply 7 by 8.
7*8=56
[tex]\frac{8}{7} =\frac{64}{56}[/tex]
This means that the side QR is 56, and since we know TR is 35, we simply need to subtract 35 from 56 to find QT: 56-35= 21
PS and QT also have the same ratio: 24/21 = 8/7 so we know that this is correct.
Hope this helped!

Derek collects quarters that have the names of the 50 U.S. States on them. He has collected 13 different state quarters in 2.25 months. His grandfather is coming to visit him in 9 months, and he wants to show his grandfather his collection. If he continues collecting quarters at the same rate, will his collection be complete by the time his grandfather visits? Explain your answer.
Answer:
Yes, his collection will be complete by the time his grandfather visits
Step-by-step explanation:
Here, we want to know if his collection would be complete by the time his grandfather visits.
From the question;
he has collected 13 different quarters in 2.25 months
At the same rate, x different quarters will be collected in 9 months
Thus, mathematically;
x * 2.25 = 13 * 9
x = (13 * 9)/2.25 = 52
Thus, at this rate he would have collected 52 quarters in 9 months.
Since he has only 50 to collect, it means his collection would be complete by the time his grandfather visits

Isolate x from xk-x that is, factorize x and you have U=x(k-1)

An acorn is falling from 13 feet in the air. If it descends 4.8 feet every second, write and solve an equation to determine how long it will take for the acorn to be 1 foot above the ground. please put the equation and answer please.
Using a linear function, it is found that:
The equation that has to be solved is: [tex]-4.8t + 13 = 1[/tex]It takes 2.5 seconds for the acorn to be 1 foot above the ground.--------------------------------
A linear function modeling the height after t seconds has the following format:
[tex]h(t) = at + h(0)[/tex]
In which:
a is the slope, which is the rate of change of the height.h(0) is the initial height.The acorn is falling from 13 feet, thus [tex]h(0) = 13[/tex]It descends at a rate of 4.8 feet every second, thus the slope is negative, that is, [tex]a = -4.8[/tex]The equation for the height after t seconds is:
[tex]h(t) = -4.8t + 13[/tex]
The acorn is 1 foot above ground when: [tex]h(t) = 1[/tex]Thus:
[tex]h(t) = -4.8t + 13[/tex]
[tex]1 = -4.8t + 13[/tex]
[tex]-4.8t + 13 = 1[/tex]
[tex]4.8t = 12[/tex]
[tex]t = \frac{12}{4.8}[/tex]
[tex]t = 2.5[/tex]
It takes 2.5 seconds for the acorn to be 1 foot above the ground.

Step-by-step explanation:
Which function inputs will result in a horizontal stretch of the function f(x) = x? Check all that apply. F f(StartFraction 3 Over two EndFraction x) f(x + 2) f f(StartFraction one-half EndFraction x) f(x – 3.2) f(x) f f(StartFraction 2 Over 3 EndFraction x)
Answer:
The correct options are;
3) f(1/2·x)
5) f(2/3·x)
Step-by-step explanation:
The given parameter is presented here as follows;
f(x) = x
Therefore;
f(x) = y = x
Comparing with the general equation for a straight line, y = m·x + c, we have;
For y = x, m = 1
∴ The slope = 1
1) For f(3/2·x) = y = 3/2·x, the slope, m = 3/2 which is a steeper slope than m=1 and therefore a has more increase in y than in x values or has a vertical stretch rather than a horizontal stretch
2) For f(x + 2) = y = x + 2, the slope, m = 1 which gives an equal slope of m = 1 to the slope in the question, f(x) = x, resulting in no change in stretch
3) For f(1/2·x) = y = 1/2·x, the slope, m = 1/2 which is a gentler slope slope than m=1 as y increase half unit, for each unit increase in x and the function is horizontally stretched
4) For f(x - 3/2) = y = x - 3/2, the slope, m = 1 which gives an equal slope of m = 1 to the slope in the question, f(x) = x, resulting in no change in stretch
5) For f(2/3·x) = y = 2/3·x, the slope, m = 2/3 which is a gentler slope slope than m = 1 as y increase 2/3 unit, for each unit increase in x and the function is horizontally stretched.
