Jerry has a part-time job at a supermarket. The ordered pairs show the number of hours he worked for (input values) and the number of dollars (output values) he earned over a five week period. (6,72) (8,96) (5.5, 66) (9,108) (7,84) Are the ordered pairs a relation?
Answer:
Yes
Step-by-step explanation:
The ordered pairs are (6,72) (8,96) (5.5, 66) (9,108) (7,84).
The number of hours worked is [tex]x[/tex] and the money earned is [tex]y[/tex].
Let us divide the values of [tex]y[/tex] by [tex]x[/tex]
[tex]\dfrac{72}{6}=12[/tex]
[tex]\dfrac{96}{8}=12[/tex]
[tex]\dfrac{66}{5.5}=12[/tex]
[tex]\dfrac{108}{9}=12[/tex]
[tex]\dfrac{84}{7}=12[/tex]
The fuction which defines the above ordered pairs is [tex]y=12x[/tex]
It can be seen that the amount of money earned is 12 times the number of hours worked.
So, per hour Jerry earns 12 dollars.
Hence, the ordered pairs are relation.

f the line with equation y=−2x+7 is rotated 90° clockwise about the origin, what are the coordinates of the image of its y-intercept?
A. (2,0)
B. (7,0)
C. (0,−7)
D. (−7,0)
Answer:
B
Step-by-step explanation:
I looked it up
The line with equation y=−2x+7 is rotated 90° clockwise about the origin, the coordinates of the image of its y-intercept is D (−7,0).
What is y-intercept of a function?The intersection of the graph of the function with the y-axis gives y-intercept of that function.
The y-intercept is the value of y on the y-axis at which the considered function intersects it.
Assume that we've got: y = f(x)
At y-axis, we've got x = 0, so putting it will give us the y-intercept.
Thus, y-intercept of y = f(x) is y = f(0)
To find the y-intercept of the line y=-2x+7. When x=0 we have that y=-2·0+7, y=7,
then point (0,7) is the y-intercept.
When we rotate this line 90° clockwise about the origin, then point (0,7) will be placed on the x-axis in positive x-direction.
Rotation preserves the distances, then the coordinates of the image are (7,0).
The correct choice is D (−7,0).

If A = 117 degrees, B = 12 degrees, and b = 12, find a. Round to the nearest tenth.
Answer:
a = 51.4Step-by-step explanation:
sinA = sinB
a b
sin(117) = sin(12)
a 12
a * sin(12) = 12 * sin(117)
a = 12 * sin(117)
sin(12)
a = 51.4

Step-by-step explanation:
Emma's grandmother sent her an $80 bookstore gift card for her birthday. Emma wants to make sure that her purchases don't exceed the amount of her gift card. So far, she has selected books that cost $8.95, $11.95, $22.25, and $24.95. She has also found a calendar she likes for $8.25. Round each item up to the next dollar to overestimate the total cost of the items in Emma's shopping basket.
Answer: total cost of the estimated items = $76
Step-by-step explanation:
Step 1
Rounding up each item to the next dollar
Book 1 = $8.95 ≈ $9.00
Book 2 = $11.95≈ $12.00
Book 3 = $22.25≈$22.00
Book 4 = $24.95≈$25.00
Calendar = $8.25 ≈$8.00
Step 2
The total estimated cost of items in Emma's shopping basket =$9.00+$12.00+$22.00+$25.00+$8.00
=$76 which did not exceed the amount of bookstore gift card of $80 sent by her grandmother.
Answer: 78$
Actual Estimate
$8.95 --------------------------$9.00
$11.95--------------------------$12.00
22.25--------------------------$23.00
$24.95------------------------$25.00
$8.25--------------------------$9.00
Then add the estimate numbers to get $78

(if you don't want to do all of this you can use
Step-by-step explanation:
((3•5x2) + 7x) - 2
Factoring 15x2+7x-2
The first term is, 15x2 its coefficient is 15 .
The middle term is, +7x its coefficient is 7 .
The last term, "the constant", is -2
Step-1 : Multiply the coefficient of the first term by the constant 15 • -2 = -30
Step-2 : Find two factors of -30 whose sum equals the coefficient of the middle term, which is 7 .
-30 + 1 = -29
-15 + 2 = -13
-10 + 3 = -7
-6 + 5 = -1
-5 + 6 = 1
-3 + 10 = 7 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -3 and 10
15x2 - 3x + 10x - 2
Step-4 : Add up the first 2 terms, pulling out like factors :
3x • (5x-1)
Add up the last 2 terms, pulling out common factors :
2 • (5x-1)
Step-5 : Add up the four terms of step 4 :
(3x+2) • (5x-1)
Which is the desired factorization
Answer:
(5x-1)(3x+2)

A barrel contained 60 gallons of water. Water leaked out of the barrel at a rate of 6 gallons every 3 days. At this rate, how many days did it take for all 60 gallons of water to leak out of the barrel?
Can you solve this by explaining.
Answer:
The answer is 1
Step-by-step explanation:
Start by solving the division part of the equation. In order to do that, you have to flip the fraction (reciprocal) and switch from division to multiplication, thus getting 3 x 3 = 9. Now you have 9 – 9 + 1, and from there you can simply work from left to right and get your final answer: 1.

Write an expression to describe the sequence below. Use n to represent the position of a term in the sequence, where n = 1 for the first term. -91, -194, -291, -388
Answer:
[tex]T_n = -97n[/tex]
Step-by-step explanation:
The actual sequence is: -97, -194, -291, -388
Required
Determine the nth term
nth term of an arithmetic progression is:
[tex]T_n = T_1 + (n - 1)d[/tex]
Where
[tex]T_1 = First\ Term = -97[/tex]
[tex]d = Common\ Difference = -194 - (-97) =-97[/tex]
So:
[tex]T_n = T_1 + (n - 1)d[/tex] becomes
[tex]T_n = -97 + (n - 1) * -97[/tex]
[tex]T_n = -97 -97n + 97[/tex]
Collect Like Terms
[tex]T_n = -97n + 97-97[/tex]
[tex]T_n = -97n[/tex]
Hence, a term of the sequence is:
[tex]T_n = -97n[/tex]
Please help me circles.....
Answer:
95
Step-by-step explanation:
The equation is
x×2=285-x
3x=285
x=95
Answer:
x = 75°
Step-by-step explanation:
There are many Circle Geometry Rules. We will be using the following:
The angle at the centre of the circle is twice the angle at the circumference.
x = the angle opposite 285 - x.
This means that 360 - (285 - x) = 2x
360 - 285 + x = 2x
75 + x = 2x
We can simplify this by taking away x from both sides.
75 = x
We can check this by substituting x into the orginal equation.
360 - (285 - x) = 2x
360 - (285 - 75) = 2 * 75
360 - 210 = 2 * 75
150 = 2*75
150 = 150
