find the slip of every line that is parallel to the graph of the equation x-8y=-1
Answer:
1/8
Step-by-step explanation:
x-8y=-1
First, put the equation in slope intercept form ( y= mx+b where m is the slope and b is the y intercept)
-8y = -x-1
y = 1/8x +1/8
The slope is 1/8 and the y intercept is 1/8
The slope for parallel lines is the same for all parallel lines
1/8

1 Solve the system of equations by the substitution method. 5x+10y = 30 4x + 8y = 36 Select the correct choice below and fill in any answer boxes within your choice. A. The solution is (Simplify your answer. Type an ordered pair.) B. There are infinitely many solutions: {(x,y)|5x + 10y = 30} or {(x,y)|4x + 8y = 36}. C. There is no solution: Tor .
The system of equations:
5x + 10y = 30
4x + 8y = 36
Has no solutions, the correct option is C.
How to solve the system of equations?Here we have the system of equations:
5x + 10y = 30
4x + 8y = 36
We want to use the substitution method, then we need to isolate one of the variables. Let's work with the second equation:
4x + 8y = 36
Divide by 4:
x + 2y = 9
x = 9 - 2y
Now replace that in the other equation to get:
5*(9 - 2y) + 10y = 30
45 - 10y + 10y = 30
45 = 30
This is a false equation, thus, the system has no solutions.

Athlete J runs 2/3 of a mile in 8 minutes. Athlete H runs 2 3/4 miles in 1/2 hour.
1: If Athlete J continues at that speed, how long will it take to run one mile?
2: How long will it take Athlete J to run 5 miles at that same speed?
3: Who runs faster, J or H? Why?
The number of minutes it would take Athlete J to run one mile is 12 minutes.
The number of hours it would take Athlete h to run 5 miles is 10/11 hour.
Athlete h runs faster because his average speed is greater than that of Athlete J.
In order to determine the time it would take Athlete J to run one mile, the average speed has to be determined.
Average speed = total distance / time
2/3 ÷ 8
2/3 x 1/8 = 1/12 mile / minute
Time it would take Athlete J to run one mile = distance / speed
1 ÷ 1/12 = 12 minutes
Average speed of Athlete H = 2 3/4 ÷ 1/2
11/4 x 2 = 5 1/2 miles / hour
Time it would take Athlete H to run 5 miles = distance / speed
5 ÷ 11/2
5 x 2/11 = 10/11 hours

Radius = 7cm , Circumference = 43.96cm
Step-by-step explanation:
To find the radius, you divide the diameter by 2.
14 / 2 = 7cm
To find the circumference, you multiply 兀 ( 3.14 ) with the diameter
兀d = 兀 x 14 = 43.96cm
Using the diagram and information below to create and solve an equation m<2 =(y+10)° and m<4=(3y-24)° what is m <2
Step-by-step explanation:
m∠2 = m∠4
y + 10 = 3y - 24
y - 3y = -24 - 10
-2y = -34
y = -34/-2
y = 17
m∠2 = y + 10
m∠2 = 17 + 10
m∠2 = 27°
−38d−57≥−19d+76 solve for d
Answer:
Step-by-step explanation:
- 38d - 57 ≥ - 19d + 76
- 38d + 38d - 57 - 76 ≥ - 19d + 38d + 76 - 76
-133 ≥ 19d
-133/19 ≥ 19/19d
-7 ≥ d
Answer:
[tex]d\leq -7[/tex]
Step-by-step explanation:
Move all terms containing [tex]d[/tex] to the left side of the inequality.
Add [tex]-19d[/tex] to both sides of the inequality.
[tex]-38d-57+19d\geq 76[/tex]
Add [tex]-38[/tex] and [tex]19d.[/tex]
Move all terms not containing [tex]d[/tex] to the right side of the inequality.
Add [tex]57[/tex] to both sides of the inequality.
[tex]-19d\geq 76+57[/tex]
Add [tex]76[/tex] and [tex]57.[/tex]
[tex]-19d\geq 133[/tex]
Divide each term by [tex]-19[/tex] and simplify.
Divide each term in [tex]-19d\geq 133[/tex] by [tex]-19[/tex]. When multiplying or dividing both sides of an inequality by a negative value, flip the direction of the inequality sign.
[tex]\frac{-19d}{-19} \leq \frac{133}{-19}[/tex]
Cancel the common factor
[tex]\leq \frac{133}{-19}[/tex]
Divide [tex]133[/tex] by [tex]-19.[/tex]
[tex]d\leq -7[/tex]
The result can be shown in multiple forms.

Rachel is blowing up a balloon so that the diameter increases at the rate of 10 cm/sec. At what rate must she blow air into the balloon when the diameter measures 4 cm
Using implicit differentiation, it is found that she must blow air at a rate of 251.33 cm³/sec.
A balloon has a spherical format.The volume of a sphere of radius r is given by:
[tex]V = \frac{4\pi r^3}{3}[/tex]
The radius is half the diameter, hence:
[tex]r = \frac{d}{2}[/tex]
[tex]r^3 = \frac{d^3}{8}[/tex]
[tex]V = \frac{4\pi d^3}{24} = \frac{\pi d^3}{6}[/tex]
Applying implicit differentiation, the rate of change of the volume is:
[tex]\frac{dV}{dt} = \frac{d^2 \pi}{2}\frac{dd}{dt}[/tex]
The diameter increases at the rate of 10 cm/sec, hence [tex]\frac{dd}{dt} = 10[/tex].It is of 4 cm, hence [tex]d = 4[/tex]The rate that she must blow air is:
[tex]\frac{dV}{dt} = \frac{d^2 \pi}{2}\frac{dd}{dt}[/tex]
[tex]\frac{dV}{dt} = \frac{4^2 \pi}{2}(10)[/tex]
[tex]\frac{dV}{dt} = 251.33[/tex]
She must blow air at a rate of 251.33 cm³/sec.

Can someone please help how I could find the square root for 121? Please explain step by step to get marked as brainliest!
Answer:
+ or - 11
Step-by-step explanation:
To find the square root of 121, think of a number that multiplied by itself would get to 121. This number is 11. However, do remember that the number could also be negative 11 bencause a negative times a negative becomes positive. I would advise you to try memorizing the squares of 0 to 15 to help you with this. Otherwise, you can just use a calculator.

The length of a rectangle is 7 less than the width. If the
perimeter is 50. What is the length and width? Write
an equation for the situation and solve.
Answer:
Step-by-step explanation:
Let width = w
Length = w - 7
Perimeter = 2*(length + width)
2*(w-7 + w) = 50
2* (2w - 7) = 50
2*2w - 7*2 = 50
4w - 14 = 50
Add 14 to both the sides
4w = 50+ 14
4w = 64
Divide the entire equation by 4
w = 64/4
w = 16 units
Length = 16 - 7 = 9 units

Answer:
218
-72
12° C
Step-by-step explanation:
The magnitude of a single number is the positive version of that number.
We write it mathematically like this:
|−218|=218
|-12|=12
The magnitude of a number is also known as the absolute value, and literally means the 'size' of the number, not worrying if it is positive or negative.
For numbers such as 1, 2, 3, and so on, the magnitude is simply the number itself. If the number is negative, the magnitude becomes the absolute value of the number. For example, the magnitude of 10 is 10. The magnitude of -10 becomes the absolute value of -10, which is 10.
