The bells are adding a new room to their house. The room will be a cube with volume of 4,913 feet cubed. They are going to put in hardwood floors, and the contractor charged $10 per square foot. How much will the j hardwood floors cost?

Answer:

3y = -2x + 24

y = -2/3x + 8

Step-by-step explanation:

Answer:

The slope-intercept form is y=mx+b y = m x + b

Step-by-step explanation:

where m m is the slope and b b is the y-intercept. Subtract 2x 2 x from both sides of the equation. Divide each term by 3 3 and simplify. Divide each term in 3y=24−2x 3 y = 24 - 2 x by 3 3 .

Answer:

m∠1 = 52, m∠2 = 60

Step-by-step explanation:

68 and ∠2 are interior angles. 128 is exterior angle.

Formula : -

Sum of two interior angles = Exterior angle

68 + ∠2 = 128

∠2 = 128 - 68

∠2 = 60

∠1 and 128 are linear pair angles. Sum of linear pair angles is 180,

∠1 + 128 = 180

∠1 = 180 - 128

∠1 = 52

Answer: 6003.2

Step-by-step explanation:

a) 3.2a, -4 1/3a, -a

b) -2.133a+6

y=-2x+7

Step-by-step explanation:

line segment xy has endpoints x(5 7) and y(-3 3)

for the equation of the perpendicular bisector of line segment xy

slope of line segment xy = 7-3 / 5+3

= 4/8

=1/2

so slope of perpendicular bisector is -2

as m1m2= -1 or m1= -1/m2

As perpendicular bisector goes through midpoint of xy , let's find midpoint of xy

midpoint(x,y) = (5-3 / 2 , 7+3 / 2)

=(2/2, 10/2)

=(1,5)

find the equation of line(perpendicular bisector) passing through (1,5) and the slope -2

y-5 = -2(x-1)

y-5 =-2x+2

y=-2x+7

A positive correlation is a relationship between two variables in which both variables move in the same direction. Therefore, when one variable increases as the other variable increases, or one variable decreases while the other decreases.

128 pencils divided by 6 pencils that can be put in a box; 128÷6=21 with a remainder of 3

Martin needs 3 more pencils for the last box, beacuse he has 3 leftovers and 6 can go into the box. 6-3=3

Answer:

f(x) = x³ + 19x² + x + 19

Step-by-step explanation:

Zeros: -19 , -i, complex conjugate root: +i

Function: (x+19)(x+i)(x-i) = 0

(x + 19) (x² - i²) = (x + 19) ( x² + 1) = x³ + 19x² + x + 19

check: when x = 1

f(1) = 1 + 19 + 1 +19 = 40

Answer: 1,200 brainliest plsss

Step-by-step explanation:

The obtained coordinate points to plot the graph are matching with graph A. Therefore, option A is the correct answer.

Given that, a company charges a delivery fee of $50 to deliver plotting soil and each cubic yard of plotting soil costs $50.

In mathematics, and more specifically in graph theory, a graph is a structure amounting to a set of objects in which some pairs of the objects are in some sense "related".

Let the total cost be y and the number of cubic yards be x.

Now, the equation to represent the given situation is y = 50+50x

By substituting x = 0, 1, 2, 3, 4, 5,....we get

y = 50+50(0) = 50

y = 50+50(1) = 100

y = 50+50(2) = 150

y = 50+50(3) = 200

y = 50+50(4) = 250

So, the coordinates to plot the graph are (0, 50), (1, 100), (2, 150), (3, 200) and (4, 250) and so on.

The obtained coordinate points to plot the graph are matching with graph A. Therefore, option A is the correct answer.

Answer:

I believe it is answer b.

Step-by-step explanation:

You multiply 4x and - 7 by 1/5 which gives you 4/5x and 1 2/5. You add 4/5x and 2/5x as they are like terms and get 1 1/5x. The equation then becomes 1 1/5 - 1 2/5

Answer:

[tex]0 \: I \: think.[/tex]

Answer:

C.  Yes, there is an x-value that is exactly zero. This is true because zero is our starting point in our profits. The x and y value would be (0,0) as we have just begun to produce energy units. Once the graph starts to increase, we cannot have a point at exactly zero, unless the profits have a dramatic drop to the x value of 0. This would then be (0, at a number of diminishing returns)

Answer:

c. I am writing extra stuff to be able to send it lol

Step-by-step explanation:

7 45 - 3 =4. 45

The derivative at x = 3 does not exist.

To see why, recall the definition of absolute value:

[tex]|x| = \begin{cases}x&\text{if }x\ge0\\-x&\text{if }x<0\end{cases}[/tex]

If x - 3 ≥ 0, then

2 + |x - 3| = 2 + (x - 3) = x - 1

and the derivative of this piece is 1 for all x > 3.

If x - 3 < 0, then

2 + |x - 3| = 2 - (x - 3) = 5 - x

and its derivative is -1 for all x < 3.

The derivatives to either side of x = 3 are not the same, so f '(x) is not continuous and indeed does not take on any value at this point.

Negative 9.5

Step-by-step explanation:

Answer:

200

Step-by-step explanation:

You can simply just graph it and see where the points intersect, or you can do it algebraically.

0.45x+29.99=0.40x+39.99 subtract 29.99 both sides

0.45x=0.40x+10.00 subtract .40x both sides

0.05x=10.00 divide both sides by 0.05

x=200

Answer:

$2.57

Step-by-step explanation:

Create an equation.

7x + 3 = 21

Subtract 3 from both sides of the equation.

7x = 18

Divide 7 from both sides to find x.

18/7 = x,

x = 2.57
