the table represents the points on the graph of a linear function. Which of the following equations best represents the data in the table?
9514 1404 393
Answer:
f(x) = 3x +5
Step-by-step explanation:
The x-values change by 1 from the first line to the second.
The y-values change by -13-(-16) = 3 from the first line to the second.
Then the "rate of change" is ∆y/∆x = 3/1 = 3. This will be the coefficient of x in the equation. The last choice is appropriate:
f(x) = 3x + 5
aquelyn’s earning m are a function of the number of lawns n she mows at a rate of $12 per lawn
Answer:
m = 12n
Step-by-step explanation:
M is the amount that she would earn at the end of the day. She charges 12 dollars per lawn and then you multiply that by n which is going to be how many lawns she mowed.

What value of x is in the solution set of 8x - 6 > 12 + 2x?
0 -1
оо
0 3
O 5
Answer:
3 is the correct answer
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :
8*x-6-(12+2*x)>0
6x - 18 = 6 • (x - 3)
The value of the inequality is x > 3 , which is 5
What is an Inequality Equation?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
8x - 6 > 12 + 2x
Subtracting 2x on both sides , we get
6x - 6 > 12
Adding 6 on both sides , we get
6x > 18
Divide by 3 on both sides , we get
x > 3
So , the value of x is numbers greater than 3
Hence , the inequality is x > 3

How much closer to the sun is one planet than the other?
Answer:
C. 7.79 x 10^8
Step-by-step explanation:
Your Equation: (eight-point-one multiplied by ten to the eighth power) subtracted by (nine-point-one multiplied by ten to the seventh power)
so first we find out how much are in the parentheses :D
(8.7 x 10^8) = 870,000,000
(9.1 x 10^7) = 91,000,000
now you subtract 870,000,000 by 91,000,000.
870,000,000
- 91,000,000
---------------------
779,000,000
converted back to standard form...

A prop for a school play is a sphere that will be hung from the ceiling. The surface area of the sphere is 5 024 cm'. If the surface area of the sphere can be found by using the formula SA = 4πr^2. where r is the radius, what is the radius of the sphere, to the nearest cm?
Answer:
The radius of the sphere, to the nearest cm:
[tex]r\approx 20[/tex] cm
Step-by-step explanation:
The surface area of a sphere is given by the formula
A = 4πr²
where r is the radius of the sphere.
Given
The surface area of sphere A = 5024 cm²The radius of the sphere can be determined such as
[tex]A\:=\:4\pi r^2[/tex]
[tex]r\:=\:\frac{1}{2}\sqrt{\frac{A}{\pi }}[/tex]
Plug in Surface Area of sphere = 5024, π = 3.14 in the formula
[tex]\:r\:=\:\frac{1}{2}\sqrt{\frac{5024}{3.14}}\:\:[/tex]
[tex]r\approx 20[/tex] cm
Therefore, the radius of the sphere, to the nearest cm:
[tex]r\approx 20[/tex] cm

please help. problem involving magic squares
Step-by-step explanation:
First, let us find the magic sum in each row/column/diagonal.
Sum of numbers from 1 to 9 = 45.
45 divide by 3 rows = 15 each row.
The magic sum is 15.
For the diagonals, we have:
8 + 5 + x = Magic sum = 15,
6 + 5 + y = Magic sum = 15.
Therefore x = 2 and y = 4.

Every day Isabel swims 10 to 20 laps in a 50-meter pool. She tracks the numbers of laps she swims and how long it takes her to complete the laps, in minutes
Choose the correct answer below.
OA. The domain consists of all integers greater than or equal to 10 and less than or equal to 20
OB. The domain consists of all integers less than or equal to 20
OC The domain consists of all integers greater than or equal to 0
OD. The domain consists of all integers greater than or equal to 0 and less than or equal to 20
O E. The domain consists of all integers greater than 0 and less than or equal to 20
Answer:
Step-by-step explanation:
A vertical asymptote represents a value at which a rational function is undefined, so that value is not in the domain of the function. A reciprocal function cannot have values in its domain that cause the denominator to equal zero. In general, to find the domain of a rational function, we need to determine which inputs would cause division by zero.
Josh worked 30 hours last week and earned $8.50 per hour. If $32.50 was withheld from his paycheck, what was Josh's net pay?
Answer:
$222.50
Step-by-step explanation:
Hours Josh worked last week = 30
Money earned per hour = $8.50
Money withheld = $32.50
Josh's net pay = (30 x 8.50) - 32.50
= 255 - 32.50
= $222.50

Given
AB: AC = 1:2
AB= 3x-4
AC= 2x + 12
show that
AC: BC = 2:3
BС= 7X-2
Answer:
Step-by-step explanation:
AB/AC =1/2
(3x-4)/(2x+12)=1/2
2(3x-4) = 1(2x+12)
6x-8=2x+12
4x=20
X=5
AC/BC =3x-4/7x-2=22/33=2/3
AB/AC=3x-4/7x-2=22/33=2/3
AB/AC=3x-4/2x+12
6x-8=2x+12
You would get 4/5 still trying to work out the last mark
Step-by-step explanation:
First find x:
AB:AC=1:2
2(3x-4)=2x+12
6x-8=2x+12
4x-8=12
4x=20
x=5
Substitute:
AC=2x+12
=(2x5)+12
=10+12
=22
BC=7x-2
=(7x5)-2
=35-2
=33
22/33=2/3
Therefore AC:BC = 2:3
