Answer: y = -1/3x - 1
Step-by-step explanation:
Slope of perpendicular line is opposite reciprocal --> -1/3Using point given (-6, 1), find b.1 = -6(-1/3) + b1 = 2 + b-1 = b€400 is divided between Ann, Brian and Carol so that Ann has twice as much as Brian and Brian has three times as much as Carol. How much does Brian receives ?
Answer:
€120
Step-by-step explanation:
Let us represent
Ann = x
Brian = y
Carol = z
€400 is divided between Ann, Brian and Carol
Hence: x + y + z = €400...... Equation 1
Ann has twice as much as Brian
Hence:
x = 2y
Brian has three times as much as Carol.
y = 3z
z = y/3
We substitute
x + y + z = €400...... Equation 1
2y + y + y/3= €400
Multiply both sides by 3
2y × 3 + y × 3 + y/3 × 3 = €400 × 3
6y + 3y + y = €1200
10y = €1200
y = €1200/10
y = €120
How much does Brian receives ?
Since, Brian = y
Brian receives €120

Hey there!
Here is a graph of the points:
A scatterplot is a graph, but the points won't be able to connect in a straight line, and they have no relation.
A line of best fit is a line that goes evenly through the points, or as best as it could.
Solve for x
Is a short response
Answer:
x = 1/4
Step-by-step explanation:
[tex]log_{x}[/tex] 16 = 2 can be written as [tex]16^{x}[/tex] = 2
([tex]2^{4}[/tex])^x = 2^1
if bases are the same we can create this equation: 4x = 1
x = 1/4
Brittney attempted to order a set of numbers from least to greatest
-2.9 72/80 2.979 3 1/5 π
what does Brittney need to do to make the order correct?
She needs to convert all the numbers be be the same type ( fraction or decimal).
With the numbers she has it would be easiest to convert all the numbers to decimals.
72/80 = 0.9
3 1/5 = 3.3
Pi = 3.14
Now she can arrange the decimals in order:
-2.9, 0.9, 2.979, 3.14, 3.2
She needs to switch 3 1/5 and pi
Answer:
3 1/5 is tha one

Answer:
6969
Step-by-step explanation:
Evaluate the expression.
Answer:
40
Step-by-step explanation:
To solve this question you will need to use BEDMAS which is the order of which numbers you have to solve first. In this case you need to solve the brackets first, then the exponent, and then lastly the addition.
3^3 + 3(4 + 1/3)
= 3^3 + 3(13/3)
= 27 + 3 x 13/3
= 27 + 13
= 40
Which skateboarder is faster:
Jada, who travels 2 miles in 12 minutes at a constant speed, or
Clare, who travels 2 miles in 10 minutes at a constant speed?
Explain how you know.
Answer:
Clare is faster
Step-by-step explanation:
They are both traveling the same distance but Clare travelled it in less time which means she is going faster.
Answer: Clare
Step-by-step explanation: If it the same mile, just look whoever’s time is the least is the fastest.
Iris takes her clothes to the laundromat every 6 days, and

23 days would pass by and they would both go to the laundromat on the 24th day.
Brent spends $ 420 on his monthly bills. Of this amount, 15 % is for utilities, 1/5 is for Internet service, and 1/7 is for phone service. If the rest of the total amount is for food, how much money does Brent have for food?
Answer: $213
Step-by-step explanation:
First find out how much is spent on the other things:
Utilities
= 15% * 420
= $63
Internet services
= 1/5 * 420
= $84
Phone service
= 1/7 * 420
= $60
The amount left for food is therefore:
= 420 - money spent on other things
= 420 - 63 - 84 - 60
= $213

(n2 – 3n+ 1)(2n + 3) =
Answer:
2n³ - 3n² - 7n + 3
Step-by-step explanation:
Given
(n² - 3n + 1)(2n + 3)
Each term in the second factor is multiplied by each term in the first factor, that is
n²(2n + 3) - 3n(2n + 3) + 1(2n + 3) ← distribute the parenthesis
= 2n³ + 3n² - 6n² - 9n + 2n + 3 ← collect like terms
= 2n³ - 3n² - 7n + 3

(04.03 LC) Identify the domain of the exponential function shown in the following graph: (2 points) 5 4 2 TI y = 10 3 4 -5 -4 -3 -2 -1 all real numbers all positive numbers 1
Answer:
The domain is all real number:
i.e.
[tex]-\infty \:<x<\infty \:[/tex]
Therefore,
[tex]\mathrm{Domain\:of\:}\:10^x\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:<x<\infty \\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:\infty \:\right)\end{bmatrix}[/tex]
Step-by-step explanation:
Given the function
y = 10ˣ
Determining the domain of the function y = 10ˣ :
We know that the domain of the function is the set of input or arguments for which the function is real and defined.
In other words,
Domain refers to all the possible sets of input values on the x-axis.From the graph, it is clear that the function has no undefine points nor domain constraints.
Thus, the domain is all real number:
i.e.
[tex]-\infty \:<x<\infty \:[/tex]
Therefore,
[tex]\mathrm{Domain\:of\:}\:10^x\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:<x<\infty \\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:\infty \:\right)\end{bmatrix}[/tex]

It took Ciera 24 minutes to drive 18 miles. It took chains of one hour to drive 46 miles. Who is driving at a faster rate?
Answer:
Ciera is driving at a faster rate.
Step-by-step explanation:
You calculate speed, by dividing distance by time.
So 18 divided by 24 is 0.75. That is Ciera's speed.
And then to calculate the other person/thing's speed you have to divide 46 by 60 minutes (equal to one hour). The speed calculates to 0.7666666667
Therefore, Ciera is driving faster.

Find the reflection of the following point over the y-axis: (7, -3)
Answer:
(-7,-3)
Step-by-step explanation:
You keep the -3 since that is the y but the x will become negative because you are reflecting to the left and not the right, making the x then negative.
Answer: (-7,-3)
Step-by-step explanation:
The point (7,-3) is located in the fourth quadrant mean that if you reflect the point across the y a-xis, it should end up in the third quadrant.
If you flip a point over the y axis, the x coordinate switches.
(7,-3) ⇒ (-7,-3)
Darron bought a new PS5. He made a down payment of $300, and he will pay $50 each month until the phone is paid off. Which equation represents the relationship between x, the number of monthly payments Darron has made, and y, the total amount he has paid?
A. y= 50x + 300
B. y= -50x + 300
C. x= 50y + 300
D. y= 50x – 300
Answer:

What are the lengths of side AB and side BC?
Answer: AB=20, BC=14
Step-by-step explanation:
set AB together with the side congruent to it (which is DC)
3x-7=x+11
subtract x and add 7 to both sides
2x=18
divide both sides by 2
x=9
plug 9 in for AB.
3(9)-7
27-7=20.
now do the same for BC
Answer:
AB = 20
BC = 14
Step-by-step explanation:
ABCD is a parallelogram
Opposite sides of a parallelogram are equal.
Therefore,
AB = DC
3x - 7 = x + 11
3x - x = 11 + 7
2x = 18
x = 18/2
x = 9
AB = 3x - 7 =3*9 - 7 = 27 - 7 = 20
7y - 7 = 3y + 5
7y - 3y = 7 + 5
4y = 12
y = 12/4
y = 3
BC = 7y - 7 = 7*3 - 7= 21 - 7 = 14

Step-by-step explanation:
I hope this helps!
Hey again!
The answer to your question is 2 cm = 1 mile
We can solve this by doing 9/4.5, and we get 2. This means that every 2 centimeters in the scale drawing is equal to 1 mile in the actual.

Answer:
sum of interior angles of octagon is 1080 degrees
From figure ,
136 + 132 + 129 + 116 + 158 + 141 + 124 + x = 1080
so, x = 1080 - 936
= 144
Step-by-step explanation: Simply add the angles and substract the sum from 1080 which is the sum of interior angles of octagon
Answer:
144 degrees.
Step-by-step explanation:
There are 8 sides to this polygon so the total internal of
angles = 180( 8 - 2)
= 1080
Adding up the 7 given angle we get 936
So x = 1080 - 936
= 144.
