Answer:
a) y= 60+ 5x
b) 9 bids
Step-by-step explanation:
a) the function is y= 60+ 5x
b) 105= 60 + 5x
45= 5x
x= 45/5
x=9
there were 9 bids
Answer:
a: y = 5x + 60
b: 9 times
Step-by-step explanation:
105 = 5x + 60
-60 -60
------------------------
45 = 5x
÷5 ÷5

Which of the following possible rational roots is a root of the function f(x)=x^3-3x^2+5x-15? *
5 points
-3
-1
1
3
Given:
The function is
[tex]f(x)=x^3-3x^2+5x-15[/tex]
To find:
The root of the function from the given possible roots.
Solution:
We have,
[tex]f(x)=x^3-3x^2+5x-15[/tex]
At x=-3,
[tex]f(-3)=(-3)^3-3(-3)^2+5(-3)-15[/tex]
[tex]f(-3)=-27-27-15-15[/tex]
[tex]f(-3)=-84\neq 0[/tex]
At x=-1,
[tex]f(-1)=(-1)^3-3(-1)^2+5(-1)-15[/tex]
[tex]f(-1)=-1-3-5-15[/tex]
[tex]f(-1)=-24\neq 0[/tex]
At x=1,
[tex]f(1)=(1)^3-3(1)^2+5(1)-15[/tex]
[tex]f(1)=1-3+5-15[/tex]
[tex]f(1)=-12\neq 0[/tex]
At x=3,
[tex]f(3)=(3)^3-3(3)^2+5(3)-15[/tex]
[tex]f(3)=27-27+15-15[/tex]
[tex]f(3)=0[/tex]
Since, the value of given function is 0 at only x=3, therefore 3 is a root of given function.
Hence, the correct option is D.

The length of a rectangular sandbox is 6 feet less than 3 times the width. The perimeter of the
sandbox is 36 feet.
Which statement is true
The length of a rectangular sandbox is
6 feet less than 3 times the width. The perimeter of the sandbox is 36 feet.
Which statement is true?
a) The equation (3w − 6) +w = 36
can be used to find the width of the rectangle, and the width is 6 feet.
b) The equation(3w −6) + w =36
can be used to find the width of the rectangle, and the width is 12 feet.
c) The equation 2(3w − 6) + 2w = 36
can be used to find the width of the rectangle, and the width is 6 feet.
d) The equation 2(3w − 6) +2w = 36
can be used to find the width of the rectangle, and the width is 12 feet.
Answer:
Option c) is true
The equation 2(3w − 6) + 2w= 36
can be used to find the width of the rectangle, and the width is 6 feet.
Step-by-step explanation:
The length of a rectangular sandbox is
6 feet less than 3 times the width. The perimeter of the sandbox is 36 feet.
L = 3 × W - 6
L = 3W - 6
The formula for perimeter of a rectangle = 2(L + W)
= 2L + 2W
Hence, we substitute
P = 2L+ 2W
36 = 2(3W - 6) + 2W
36 = 6W -12 + 2W
Collect like terms
36 +12 = 6W + 2W
48 = 8W
W = 48/8
W = 6
The width is 6 feet
Which statement is true?
Option c) is true
The equation 2(3w − 6) + 2w= 36
can be used to find the width of the rectangle, and the width is 6 feet.
Guiana and jimmy are selling wrapping paper for a school fundraiser. Customers can buy rolls of plain wrapping paper and rolls of holiday wrapping paper. Hi oh sold 10 rolls of plain wrapping paper and 7 rolls of holiday wrapping paper for a total of $330. Jimmy sold 4 rolls of plain wrapping paper and 14 rolls of holiday paper for a total of $356. What is the cost of each one roll of plain wrapping paper and one roll of holiday wrapping paper?
Answer:
The answer is "p=25.63 and h= 6.24".
Step-by-step explanation:
p = cost of the plain
h = cost of the holiday
[tex]\to 10p + 7h = 330.........(i)\\\\\to 4p + 14h = 356........(ii)[/tex]
multiply by 2 in equation (i) and subtract from the equation (ii):
[tex]\to 20p + 14h = 660\\\\\to 9p + 14h = 378\\\\subtract\\\to 11 \ p =\ 282 \\\\\to p = \frac{282}{11}\\\\\to p = \$ \ 25.63[/tex]
put the value of p in equation (i):
[tex]\to 10(25.63)+7h=330\\\\\to 256.3+7h=330\\\\\to 7h=330 - 256.3\\\\\to 7h=330 - 256.3\\\\\to 7h= 43.7\\\\\to h= \frac{43.7}{7}\\\\\to h=6.24[/tex]

Answer:
119 degrees
Step-by-step explanation:
We know that a full straight line is 180 degrees. This angle is 61 degrees, so we subtract 61 from 180.
180 - 61 = 119 degrees
I hope this helped, please mark Brainliest, thank you!
Answer:
119

452 divided 15 what would be the answer of this? If anyone knows please answer
Answer:
The answer to this question is given below in the explanation section
Step-by-step explanation:
This is a simple division question.
In division there are some terms used that are:
Dividend: The number which we divide is called a dividend. In this case, 425 is a dividend
Divisor: The number by which we divide is called the divisor. In our question, it is 15.
Quotient: The result obtained is called the quotient.
Remainder: The number left over is called the remainder.
So the answer to this question is:
452/15= 30.133
so the answer is 30.1333

For this question, you will be asked to demonstrate how we can determine the answer without using a calculator: Kenton knows that a wall unit he bought is √107 ft long and the dimensions of the living room are 9 ft wide by 11 ft long. On which wall(s) could Kenton place this wall unit?
Answer:
The wall unit should be placed on the wall of length 11 ft.
Step-by-step explanation:
Given that the dimension of the room = length by width
= 11 ft by 9 ft
Applying the rule of surd to the dimensions of the room, we have:
length = 11 = [tex]\sqrt{121}[/tex] ft
width = 9 = [tex]\sqrt{81}[/tex] ft
But, the length of the wall unit = [tex]\sqrt{107}[/tex] ft
Comparing the dimensions with the length of wall unit, it can be observed that:
i. The length of the wall is greater than that of the wall unit.
ii. The width of the wall is lesser than the length of the wall unit.
Therefore, the wall unit should be placed on the wall of length 11 ft.
