Which is the answer to it

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

--------------

9 = x

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.

Answer:

6

Step-by-step explanation:

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

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:

A: -1

Step-by-step explanation:

If you look at the graph, it goes up one unit and to the left one unit. This means that the slope is -1 (or -x). This is shown by the rise over run. 1/-1= -1.

Answer:

A) -1

Step-by-step explanation:

[tex]y = mx + b\\m = \frac{y_2-y_1}{x_2-x_1} = \frac{0-(-2)}{6-0} = \frac{1}{3} \\-2 = \frac{1}{3}(0) + b\\ b = -2\\y = \frac{1}{3}(x) - 2[/tex]

Is there a picture to go with the question??

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.

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.

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.
