Answer:
Inequality Form: -1 < x < 7
Interval Notation: (-1, 7)
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Describe the transformation using the values for slope (m) and the y-intercept b. Compare the graph to the parent y = x.
Answer:
See attached
Step-by-step explanation:
y = mx + b - slope-intercept form
m- is the slope, the greater the slope the steeper the line, it gets flatter when is getting closer to zero
b- y-intercept, if be is positive it indicates vertical shift up, when negative- vertical shift down
converts 3km per hour into m per min.
Answer:
50 meters per minute

during a musical an orchestra is playing. as the music plays, the volume changes in the beginning of the piece can be modeled by the equation s=10|x-4|+50 where s represents the sound level in decibels and x represents the number of measures of music played. explain in words each step to find the following question:
at what number(s) measures played would the sound level be at 80 decibels?
Answer:
X = 1 ; x = 7
Step-by-step explanation:
Given the equation:
s=10|x-4|+50
s = sound level in decibels ; x = number of measures of music played
Take away 50 from Both right hand and left hand side of the equation
Recall s = 80
80 - 50 = 10│x - 4│+ 50 - 50
30 = 10│x - 4│
To get rid of the absolute value sign, append ± to left hand side
± 30 = 10x - 40
Minimum value of x : - 30 + 40 = 10x ; 10 = 10x ; x = 1
Maximum value of x : 30 + 40 = 10x ; 70 = 10x ; x = 7

Answer: x=
1/8y+5
Step-by-step explanation: Step 1: Flip the equation.
8x−40=y
Step 2: Add 40 to both sides.
8x−40+40=y+40
8x=y+40
Step 3: Divide both sides by 8.

if you travel 480 miles at an average speed of 40 miles per hour for how many hours were you traveling
Answer:
The answer is 12 hoursStep-by-step explanation:
To find the time taken for an object to travel given it's velocity and distance covered we use the formula
[tex]time = \frac{distance}{speed} \\ [/tex]
From the question
distance = 480 miles
speed = 40 mi/h
So we have
[tex]time = \frac{480}{40} = \frac{48}{4} \\ [/tex]
We have the final answer as
12 hoursHope this helps you

Solve for n. 170-4n=120
Answer:
n = 12.5 or 25/2
Step-by-step explanation:
170-4n = 120
1. Subtract 170 from both sides to isolate -4n.
-4n = -50
2. Divide both sides by -4 to isolate the n.
n = 12.5 or 25/2
Hope this helped!
Answer:
12.5
Step-by-step explanation:
170 - 4n = 120
-170 -170
-4n = -50
4n = 50
n = 12.5
One gallon of gasoline in Buffalo, New York costs $2.29. In Toronto, Canada, one liter of gasoline costs $0.91. There are 3.8 liters in one gallon. How much does one gallon of gas cost in Toronto? Round your answer to the nearest cent. Is the cost of gas greater in Buffalo or in Toronto? How much greater?
Answer:
-To find the cost of one gallon of gas in Toronto, you have to multiply the cost of one liter of gasoline for 3.8 as you know that there are 3.8 liters in one gallon:
$0.91*3.8=$3.46
This means that a gallon of gas cost $3.46 in Toronto.
-$3.46-$2.29=$1.17
Considering that one gallon of gasoline cost $2.29 in Buffalo and $3.46 in Toronto, the cost is greater in Buffalo. The cost is greater by $1.17.

, what is the radius of a circle with circumference 37.7 m?
Answer: r≈6
Step-by-step explanation: Using the formula
C=2πr
Solving forr
r=C
2π=37.7
2·π≈6.00014
Answer:
The radius is 6
Step-by-step explanation:
The circumference of a circle is equal to pi times the diameter. The diameter is two times the radius, so the equation for the circumference of a circle using the radius is two times pi times the radius
C=2πr
r=C
2π=37.7
2·π≈6.00014
Hope this helps!

The endpoints of MN are located at M (-4, 4) and N (2,-2). What are the coordinates of the point that divides MN such that MP: PN is equal to 2: 1?
Given:
The endpoints of MN are located at M (-4, 4) and N (2,-2).
Point P divides the line segment MN such that MP: PN = 2: 1
To find:
The coordinates of point P.
Solution:
Section formula: If a point divides a line segment in m:n, then coordinates of that point are
[tex]Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)[/tex]
Point P divides the line segment MN in 2:1. So,
[tex]P=\left(\dfrac{2(2)+1(-4)}{2+1},\dfrac{2(-2)+1(4)}{2+1}\right)[/tex]
[tex]P=\left(\dfrac{4-4}{3},\dfrac{-4+4}{3}\right)[/tex]
[tex]P=\left(\dfrac{0}{3},\dfrac{0}{3}\right)[/tex]
[tex]P=(0,0)[/tex]
Therefore, the coordinates of the point P are (0,0).
Laurie used 5 yards of fabric to make 2 costumes for the school play. How many yards of fabric would she need to make 20 more of these costumes?
Answer:
50 yards.
Step-by-step explanation:
Since we know that 5 yards can make 2 costumes, we can divide 5/2 to find 2.5 yards are needed to make one costume. Then you can multiply 2.5*20 to get 50 yards needed for 20 costumes. Hope this helps :)

Below is a scale drawing of a stage that Syla is designing. A rectangle with length 8 centimeters and width 5 centimeters. Using the scale 1 cm : 7 m, Syla calculated the width, or the shorter side of the stage, to be 35 m. She decides to change the scale to 1 cm : 10 m. What is the width of the new stage?
Answer:
50mStep-by-step explanation:
Given the dimension
Length of the rectangle = 8cm
Width = 5cm
Note that when the scale was 1:7, syla multiplied the width by a factor of 7 i.e 5*7 = 35m
If syla changes the the scale to 1 cm : 10 m for the rectangle, then the width of the shorter side will be multiplied by a factor of 10 due to the change in scale i.e;
5 * 10 = 50m
Hence the width of the new stage will be 50 m
Answer:
50m
