The incorrect work of a student to solve an equation 2(y + 6) = 4y is shown below.
Step 1: 2(y + 6) - 4y
Step 2: 2y + 8; 4y
Step 3: 2y : 8
Step 4: y = 4
Which of the following explains how to correct Step 2 and shows the correct value of y?
02 should be distributed as 2y + 12, y = 6
should be distributed as 2y + 12; y = 3
The equation should be y + 6 4y after division by 2
D The equation should De
6 = 4y after division by 2; y = 1

Answers

Answer 1

Answer:

⇒ A. 2 should be distributed as 2y + 12, y = 6

Step-by-step explanation:

Here are the steps to solve this equation:

Given:

First step: 2(y+6)-4y

Use the distributive property.

Distributive property:

⇒ A(B+C)=AB+AC

2(y+6)

2*y=2y

2*6=12

2y+12

Isolate the term of y from one side of the equations.

2y+12=4y

Subtract by 12 from both sides.

2y+12-12=4y-12

Solve.

2y=4y-12

Then, you subtract by 4y from both sides.

2y-4y=4y-12-4y

Solve.

2y-4y=-2y

-2y=-12

Divide by -2 from both sides.

[tex]\sf{\dfrac{-2y}{-2}=\dfrac{-12}{-2}}[/tex]

Solve.

Divide the numbers from left to right.

Solutions:

-12/-2=6

[tex]\Longrightarrow: \boxed{\sf{y=6}}[/tex]

Therefore, the correct answer is A. "2 should be distributed as 2y+12, y=6".

I hope this helps. Let me know if you have any questions.

The number of bags that they will need if each bag contains 500 cubic inches of confetti is 20,000

How to find the total volume ?

One bag contains 500 cubic inches of confetti.

Therefore,

1 bag = 500 inches³

The student need to fill 100 containers with the bag.

Each container can accomodates 100,000 cubic inches.

Therefore,

1 bag = 500 inches³

100,000inches³ = 1 container = 200 bags

Therefore,  

100 containers will contain 20, 000 bags of confetti.

Can someone tell me the formula of this shape so that i can solve it and would it be the ² or the ³ and last what number in this problem do i not use thank u

Answers

Answer:

660 ft³

Step-by-step explanation:

The way I'm thinking of it, we can think of it as a triangle and then extruding out from that triangle for the length.

First, the triangle:

area = base * width / 2 = 12 * 10 / 2 = 60 ft²

volume = the triangle for the length

the length is 11 feet,

so we extrude that triangle for 11 feet to get

60 ft² * 11 ft = 660 ft³

we multiply 10 ft by 12 ft by 11 ft. there are 3 instances of ft, so the corresponding exponent is therefore ³.

another way to think of the extrusion is like a rectangular prism, the formula for a rectangular prism's volume is length * width * height. we're extruding from the bottom rectangle for the whole of the height, so we multiply the area of the bottom triangle (length * width) by height.

this might be confusing so let me know if you have any questions!


43. Find an equation of the tangent line to the curve [tex]y=10^{x}[/tex] at the point (1,10)

Answers

Answer:

23x-y=13

Step-by-step explanation:

we need to find the derivative with respect to x

In(y) =In(10^x)

In(y)=xIn(10)

now we have to take the derivative with respect to x

Therefore, y'=yIn(10)

where y'=10^xIn(10), Chain rule!

note: First derivative function always give us the gradient value when x value is substituted in

Therefore, at x=1, our gradient will be m= 10^1In(10)

Gradient m=23.0 to the nearest tenth

Finding the equation of the line

y-y1=m(x-x1)

y-10=23(x-1)

y-10=23x-23

y-23x=-23+10

y - 23x = -13

so, the equation of the line tangent line is

23x - y =13

A) A = (-1, 6), B = (1, -6)
B) A = (-1, 0), B = (1, 0)
C) A = (7, 6), B = (9, -6)
D) A = (7, 0), B = (9, 0)

Answers

Answer:

B)   A = (-1, 0),  B = (1, 0)

If the transformation of AB to A'B' is (x+4, y-3),

then the transformation of A'B to AB is the reverse: (x-4, y+3)

Given

A' = (3, -3)  →  A = (3-4, -3+3) = (-1, 0)

B' = (5, -3)  →  B = (5-4, -3+3) = (1, 0)

Solve the equation by using the quadratic formula.
8x2 – 2x - 15 =0

Answers

Answer:

x = 3/2 or x = -5/4

Step-by-step explanation:

Solve for x over the real numbers:

8 x^2 - 2 x - 15 = 0

Using the quadratic formula, solve for x.

x = (2 ± sqrt((-2)^2 - 4×8 (-15)))/(2×8) = (2 ± sqrt(4 + 480))/16 = (2 ± sqrt(484))/16:

x = (2 + sqrt(484))/16 or x = (2 - sqrt(484))/16

Simplify radicals.

sqrt(484) = sqrt(4×121) = sqrt(2^2×11^2) = 2×11 = 22:

x = (2 + 22)/16 or x = (2 - 22)/16

Evaluate (2 + 22)/16.

(2 + 22)/16 = 24/16 = 3/2:

x = 3/2 or x = (2 - 22)/16

Evaluate (2 - 22)/16.

(2 - 22)/16 = -20/16 = -5/4:

Suppose the goal is to raise $600. One equation relating the calendar and poster sales to the $600 goal is 3c + 2p= 600. Suppose the company donating the calendars and posters said they would provide a total of $250 items. ​

Answers

Answer:

100 calendars and 150 posters

Step-by-step explanation:

Note it seem the "$" shouldn't be in front of 250 as it is the numbe of items

a) The second equation is

c + p = 250

b) The graph of both equations is attached

The intersection point of the lines is (100, 150)

It indicates 100 calendars and 150 posters to be donated to meet both of targets $600 and 250 items.

Answer:

Given equation:

[tex]3c+2p=600[/tex]

where:

c = number of calendarsp = number of posters

Part (a)

If the company donating the calendars and posters said they would provide a total of 250 items then:

[tex]c+p=250[/tex]

Part (b)

To graph:

Rewrite both equations to make p the subjectFind the c-interceptFind the p-interceptConnect the two points with a straight line

[tex]3c+2p=600 \implies p=300-\dfrac{3}{2}c[/tex]

[tex]\textsf{x-intercept}: \quad 300-\dfrac{3}{2}c=0 \implies c=200 \implies (200,0)[/tex]

[tex]\textsf{y-intercept}: \quad 300-\dfrac{3}{2}(0)=300 \implies (0,300)[/tex]

[tex]c+p=250 \implies p=250-c[/tex]

[tex]\textsf{x-intercept}: \quad 250-c=0 \implies c=250 \implies (250,0)[/tex]

[tex]\textsf{y-intercept}: \quad 250-0=250 \implies (0,250)[/tex]

Point of intersection (equate equations):

[tex]\begin{aligned}300-\dfrac{3}{2}c &=250-c\\50 & =\dfrac{1}{2}c\\ c & =100\end{aligned}[/tex]

[tex]p=250-100=150[/tex]

[tex]\implies \left(100,150}\right)[/tex]

The point of intersection tells us that they need to sell 100 calendars and 150 posters to reach their goal of raising $600.  Therefore, the company needs to provide 100 calendars and 150 posters (or 250 items in the ratio of calendars to posters of 2 : 3).
