Answer:
-4
Step-by-step explanation:
The form of a liner equation is y=mx+b. b is 0 in this example. So we are left with y=-4x
-4 is the m, the slope. It is also called the unit rate of change. It tells us how much y changes for each 1x unit.

571 x 32 = 18,272
Step-by-step explanation:
Okay, multiplication was always a favorite.
Think of this, 571 thirty-two times.
Write an equation for the line that passes through the given point and is parallel/perpendicular to the graph of the given point.
Parallel: Y=3x-2; (3,2)
Perpendicular: Y= -2x-1; (2,-1)
Also I will mark brainly to who explain what they did step by step
Answer:
Parallel: The slope is the same as in the previous equation. So, y=3x+b. To find the value of b, you plug in the given point, 2=3(3)+b, b=-7. So the equation is y=3x-7.
Perpendicular: The slope is the negative reciprocal when an equation is perpendicular. The negative reciprocal of -2 is 1/2. So, y=1/2x+b. To find the value of b, you plug in the given point, -1=1/2(2)+b, -1=1+b, b=-2. So the equation is y=1/2x-2.

Answer:
parallel: y = 3x -7perpendicular: y = 1/2x -2Step-by-step explanation:
The given line equations are written in "slope-intercept" form.
y = mx + b . . . . . . . . . m is the slope; b is the y-intercept
If we solve this equation for b, we find ...
b = y - mx
This is useful for completing the equation of the line through a given point when the slope is known.
ParallelA parallel line will have the same slope as the given line. The given line has a slope (x-coefficient) of 3. We can find the "b" of the line through the desired point as ...
b = y -3x
b = 2 -(3)(3) = -7
The equation of the parallel line is ...
y = 3x -7
__
PerpendicularA perpendicular line will have a slope that is the opposite reciprocal of the slope of the line it is perpendicular to. Here, the given line has a slope of -2, so the perpendicular line will have a slope of ...
-1/(-2) = 1/2
Then the y-intercept is ...
b = y -(1/2)x
b = -1 -(1/2)(2) = -2
And the equation of the perpendicular line is ...
y = 1/2x -2
__
The attached graph shows the original lines as dashed lines, and the corresponding desired lines as solid lines in the same color.
Which equation represents the line that passes through C(2,4) and is perpendicular to the graph of y=1/3x-1?
Answer:
Step-by-step explanation:
y=-3x + b the slope is the negative inverse of 1/3
4=3(2) + b
b =-2
the equation is
y=-3x - 2
slope is the negative inverse. You find the y intercept, b, by plugging in the point (2,4) to get 4=3(2)+b

Answer:
x = 10.55cm
Step-by-step explanation:
Sin 29 degrees = 7cm/x
X = 7cm / sin 29
= 10.55 cm
Answer:
x =14.4cm
Step-by-step explanation:
Sin x = opp/hyp
This is because we are given angle look into the triangle and see opp given =7 and need hypotenuse
Sin x = 7 / sin (29) = 14.4386574 cm = 14.4cm
This is because the opp is the 7 measure.
x = 14.4cm
We can prove the base is less through Pythagoras theorem
simply as c^2-b^2 = a^2
14.4386.....^2 -7^2 = c^2
sqrt 208.47 - sqrt 49 =c^2
c^2 = sqrt 159 = 7.43849023
therefore base = 7.44
To check angle 29 degrees for 3rd proof
cos (29) x 7/x= (x)
= 203 / x
check 203/29 = 7
Given a=7 and ∠α=29°,
b = 12.62833
c = 14.43866 proof
∠β = 61°
h = 6.12234
area = 44.19917
perimeter = 34.06699

Ibrahim spends 1/3 of his earnings on food and 1/4 on clothes. He then saves the rest.what fraction does he (a) spend altogether (b)save 1 What fraction does he (a) spend altogether (b) Save?
A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.
The formula for adding two fractions:
= a/b + c/d
= (ad + bc) / cd
The fraction spent altogether on food and clothes is 7/12.
What is a fraction?A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.
Example: 1/2, 1/3 is a fraction.
We have,
Fraction of earnings spend on food:
= 1/3
Fraction of earnings spend on clothes:
= 1/4
Fraction of total spending on food and clothes.
= 1/3 + 1/4
= (4 + 3) / 12
= 7/12
The formula for adding two fractions:
= a/b + c/d
= (ad + bc) / cd
Fraction of earnings saved after spending on food and clothes.
= 1 - 7/12
= (12 - 7) / 12
= 5/12
Thus,
The fraction spent altogether on food and clothes is 7/12.

Members of a softball team raised $1319.25 to go to a tournament. They rented a bus
for $776.50 and budgeted $41.75 per player for meals. Write and solve an equation
which can be used to determine p, the number of players the team can bring to the
tournament. Giving 100 points please help
Answer:
13 players
Step-by-step explanation:
Money Raised=RentedBus+Meals
1319.25=776.50+41.75p (p is for the number of players)(Now we solve for x)
Subtract 776.50 from both sides: 542.75=41.75x
Divide both sides by 41.75: 13=x
Remember that x is for the number of players so there'll be 13 players going to the tournament.
Answer:
1319.25=776.50+41.75p

Answer: The inequality is: n ≥ 36/37
Step-by-step explanation:
Let's solve your inequality step-by-step.
n − 5n + 6 ≥ −7(5n−6)−6
----------------------------------------------------------------------------------------------------------------
Step 1: Simplify both sides of the inequality.
−4n + 6 ≥ −41n + 42
----------------------------------------------------------------------------------------------------------------
Step 2: Add 41n to both sides.
−4n + 6 + 41n ≥ − 41n+ 42 + 41n
37n + 6 ≥ 42
----------------------------------------------------------------------------------------------------------------
Step 3: Subtract 6 from both sides.
37n + 6 − 6 ≥ 42 − 6
37n ≥ 36
----------------------------------------------------------------------------------------------------------------
Step 4: Divide both sides by 37.
37n/37 ≥ 36/37
n ≥ 36/37
----------------------------------------------------------------------------------------------------------------
Answer:
n ≥ 36/37

Find the domain and range for the function shown in the
graph given below.
Answer:
d{0 less than or equal to x less than or equal to 20, xer}
r{0 less than or equal to y less than or equal to -6,yer}
Step-by-step explanation:
The Domain and Range of the graph given is -
Domain ↔ [1, -6]
Range ↔ [- 21, 20]
We have a graph as shown in the figure.
We have to determine its domain and range.
What do you mean by domain and range of a function?For any function y = f(x), Domain is the set of all possible values of y that exists for different values of x. Range is the set of all values of x for which y exists.
According to question, we have -
From the graph it is clear that -
The values of y belong to the set - [1, -6]
and
The values of x belong to the set - [- 21, 20]
Therefore, according to the definition of domain and range -
Domain ↔ [1, -6]
Range ↔ [- 21, 20]
Hence, the Domain and Range of the graph given is -
Domain ↔ [1, -6]
Range ↔ [- 21, 20]

In the equation 4x² - 16x + 12 = 0, the solution is?
Answer:
x = 3 or x = 1Step-by-step explanation:
[tex] {4x}^{2} - 16x + 12 = 0 \\ {4x}^{2} - 4x - 12x + 12 = 0 \\ 4x(x - 1) - 12(x - 1) = 0 \\ (4x - 12)(x - 1) = 0 \\ [/tex]
(4x - 12) = 0 or (x - 1) = 0
[tex](4x - 12) = 0 \\ 4x - 12 = 0 \\ 4x = 0 + 12 \\ 4x = 12 \\x = \frac{12}{4} \\ x = 3 \\ [/tex]
[tex](x - 1) = 0 \\ x - 1 = 0 \\ x = 0 + 1 \\ x = 1[/tex]

4/11 - 10/8 equals?
having trouble breaking it down to get the answer
Answer:
71/44
Step-by-step explanation:
Here the LCD is the product of the two denominators given: 11*8 = 88.
We rewrite 4/11 as 32/88 and 10/8 as 110/88. Now the denominators are the same.
Combine 32/88 and 110/88. We get the sum 142/88, which reduces to 71/44.
Answer:
-39/44.
Step-by-step explanation:
We need to find the lowest common multiple of 11 and 8.
This is 88.
Now to convert the 2 fractions to denominator 88 we multiply first by
8/8 and the second by 11/11:
4/11 - 10/8
= 32/88 - 110/88
= -78/88
= -39/44

Two mechanics worked on a car. The first mechanic worked for 10 hours, and the second mechanic worked for 5 hours. Together they charged a total of $950. What was the rate charged per hour by each mechanic if the sum of the two rates was $125 per hour?
Answer:
First mechanic: $65.
Second mechanic: $60.
Step-by-step explanation:
Let the rates be x for the first mechanic and y for the second.
x + y = 125
10x + 5y = 950
Multiply first equation by - 5
-5x - 5y = -625
Adding the last 2 equations:
5x = 325
x = 65
y = 125-65 = 60 .
