у: -1, -5, -9
O y = -2x + 3 ✓ putting the value of x as 2 & y as -1⇢-1 = -2 x 2 +3
⇢-1 = -4+3
⇢-1 =-1 ✓
putting the value of x as 4 & y as -5⇢-5 = -2 x 4 +3
⇢-5 = -8 +3
⇢-5 = -5 ✓
putting the value of x as 6 and y as -9⇢ -9 = -2 x 6 +3
⇢ -9 = -12 +3
⇢ -9 = -9 ✓
O y = 2x + 3
O y = -3x + 2
O y = 3x - 2
The solution is, O y = -2x + 3, represents the linear function shown in the table.
What is function?Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable.
here, we have,
let the equation be y = -2x + 3.
putting the value of x as 2 & y as -1
⇢-1 = -2 x 2 +3
⇢-1 = -4+3
⇢-1 =-1 ✓
putting the value of x as 4 & y as -5
⇢-5 = -2 x 4 +3
⇢-5 = -8 +3
⇢-5 = -5 ✓
putting the value of x as 6 and y as -9
⇢ -9 = -2 x 6 +3
⇢ -9 = -12 +3
⇢ -9 = -9 ✓
we get, that this satisfies the conditions,
so, we have, O y = -2x + 3
Hence, The solution is, O y = -2x + 3, represents the linear function shown in the table.

The length of the subtended arc, if the radius is 12 units and the central angle measures 45 degrees is 9.42.
What is the length of the arc?The arc length is defined as the interspace between the two points along a section of a curve.
An arc of a circle is any part of the circumference.
The length of the subtended arc, if the radius is 12 units and the central angle measures 45 degrees is given by;
[tex]\rm ARC =2\pi r \times \dfrac{\theta}{360}\\\\ARC =2\pi \times 12 \times \dfrac{45}{360}\\\\ ARC =3\times 3.14\\\\ARC =9.42[/tex]

9. You are installing a swimming pool. Write a polynomial that represents the area of the walkway
8 ft width of the pool
(6x-4) ft length (of the pool)
(2x + 6) ft length of the Walk way
10x ft width of the Walk way
Answer:
(10x² +12x +32) ft²
Step-by-step explanation:
The area of the walkway around the pool is the difference between the area of the entire rectangle, and the area of the pool. The area of each rectangle is found by multiplying its length and width.
__
Overall area:
((2x +6) ft) × (10x) ft = (10x² +60x) ft²
Pool area:
((6x -4) ft) × (8 ft) = (48x -32) ft²
Walkway area:
overall area - pool area = ((10x² +60x) ft²) -((48x -32) ft²)
= (10x² +12x +32) ft²
Dan read 126 pages of his book. He has 68% of his book left to read. How many pages are
in his bool
Enter the number in the box.
Answer:
394
Step-by-step explanation:
If he has 68% left to read, then he read 100% - 68% = 32%.
32% of the number of pages, n, equals 126 pages.
0.32n = 126
n = 126/0.32
n = 393.75
Answer: 394

Midpoint Formula
M = (x₁ + x₂ / 2, y₁ + y₂ / 2)#1 : (-2,5) and (0. 2)
M = (-2 + 0 / 2, 5 + 2 / 2)M = (-2/2, 7/2)M = (-1, 7/2)M = (-1, 3.5)#2 : (0, 3) and (0, -3)

Roderick works as an architectural draftsman for an engineering firm. His monthly salary is $3,204.17. After taxes and other deductions, he takes home $2,317.56. His wife works as an electronics technician and earns $25.07 per hour. She works 37.5 hours each week and is paid every other week.
Based on this information, what is their gross income for six months?
Taxes are not deducted for gross income.
Roderick's gross income for 6 months = $3,204.17 × 6 = $19,225.02
Wife's gross income for 6 months = $25.07 × 37.5 × 26 = $25,057.5
Total gross income = $44,282.52

Answer:
D) y > -ax + b
E) y < ax - b
Step-by-step explanation:
The line with the negative slope (blue on attached diagram):
negative slope → -axshading above y → y >positive y-intercept → +bTherefore: y > -ax + b
The line with the positive slope (red on attached diagram):
positive slope → axshading under y → y <negative y-intercept → -bTherefore: y < ax - b

Question
You are writing a book about a 3,030-mile bike race across the United States. You wonder about a title, and how many pedal strokes it takes to finish the race. Assuming a pedal stroke is about 16 feet on average, which of the following would be the best book title?
Answer:
Step-by-step explanation:
"One Billion Pedals to Finish " seems like a good title to me, but, if you want a math correct title, then,
3,030mi* 5280 ft. per mile = 15,998,400 ft.
now divide pedals into ft.
15,998,400 / 16 =999,990 :D do you think they did that on purpose? made the answer 99999 :D I think so, soooo name the title "One million pedals to finish" or to be math accuate, but less "pop" , then "999,990 petals to finish"
I like "One million pedals" which do you like? :/ The very first answer? but totally wrong? :D, yeah, go with the " One Billion Pedals" sure, it's inaccuarate :DDD but very amazing :P
Square PQRS is drawn inside rectangle ABCD such that side PQ is on side AB and side SR is on side DC, as shown below. Line segment PB is 17 inches long and line segment DR is 15 inches long. What is the perimeter of rectangle ABCD?
The perimeter of the rectangle ABCD is the sum of its side lengths, and the perimeter is 70 inches
How to determine the perimeter of ABCD?The question is incomplete, as the figure of the square and the rectangle are not given; so I will give a general explanation
The perimeter (P) of the rectangle ABCD is calculated using:
P = AB + BC + CD + DA
Since the opposite sides are equal, the formula becomes
P = 2 * (AB + BC)
Assume that the values of AB and BC are 20 and 15, respectively;
The equation becomes
P = 2 * (20 + 15)
Evaluate the product
P = 70
Hence, the perimeter of the rectangle ABCD is 70 inches (using the assumed values)
