Answers

Answer 1

Answer:

(a) [tex]y = 4.5x + 22[/tex] -- The equation

(b) 31 inches

Step-by-step explanation:

Given

See attachment

Solving (a): The equation of the trend line.

We start  by calculating the slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Where

[tex](x_1,y_1) = (0,22)[/tex]

[tex](x_2,y_2) = (4,40)[/tex]

So, we have:

[tex]m = \frac{40 - 22}{4 - 0}[/tex]

[tex]m = \frac{18}{4}[/tex]

[tex]m = 4.5[/tex]

The equation is then calculated using:

[tex]y = m(x-x_1)+y_1[/tex]

Where:

[tex](x_1,y_1) = (0,22)[/tex]

[tex]m = 4.5[/tex]

[tex]y = 4.5(x - 0) + 22[/tex]

Open bracket

[tex]y = 4.5x - 0 + 22[/tex]

[tex]y = 4.5x + 22[/tex]

(b) The height of a 2 year old.

To do this, we substitute 2 for x in [tex]y = 4.5x + 22[/tex]

[tex]y = 4.5 * 2 + 22[/tex]

[tex]y = 9+ 22[/tex]

[tex]y = 31[/tex]

The prediction is 31 inches

Lamont has 30 books to pack in boxes . Each box holds 7 books. If he fills each box, how much books are left over ?

Answers

Answer:

B. 2

Step-by-step explanation:

To solve this, we need to divide 30 by 7. 30/7=4 R2

The remainder is 2, so there are 2 books left over.

Hope his helps and have an amazing day *^____^*

Answer:

2

Step-by-step explanation:

If 1 box holds 7 books...

2 boxes hold 14 books.

3 boxes hold 21 books.

4 boxes hold 28 books.

5 boxes hold 35 books.

However, since there are only 30 books, the 5th box won't be completely filled up. This gives us the answer: If Lamont fills up each box he would have 30-28, or 2 books left over.

Show the solution for a two square room have a total floor area of 89m rise to power 2 one room is 3mlonger each way than the other find the dimensions of the two rooms

Answers

Answer:

side length of the smaller room = 5 m

Side length of the larger room = 8 m

Step-by-step explanation:

Total area of two square room = 89 m²

Area of a square = side²

Let

x = side of the smaller square

x + 3 = side of the longer square

Total area = area of room A + Area of room B

89 = x² + (x + 3)²

89 = x² + x² + 6x + 9

89 - 9 = 2x² + 6x

2x² + 6x = 80

2x² + 6x - 80 = 0

Divide through by 2

x² + 3x - 40 = 0

Solve quadratic equation using factorization method

x² + 8x - 5x - 40 = 0

x(x + 8) -5(x + 8) = 0

(x - 5) (x + 8) = 0

(x - 5) = 0 (x + 8) = 0

x = 5 x = -8

The side length of a square room can not be a negative value

Therefore, side length of the smaller room = 5 m

Side length of the larger room = 5 + 3

= 8 m

Slope intercept form

Answers

Is the question complete??

The slope intercept form of the equation x + 6y - 2 is y = -x/6 + 1/3.

What is the slope intercept form of an equation ?

When any equation is represented in the y = mx +c form, it is called the slope intercept form of the equation.

Here m is slope and c is constant.

The given equation is,

x + 6y = 2,

To find the slope intercept form of the equation,

Solve the equation,

6y = -x + 2

y  = -x/6 + 2/6

y = -x/6 + 1/3

The slope intercept form of the equation is y = -x/6 + 1/3.

Step-by-step explanation:

Since 648 flowers were arranged in 27 large vases, with the same number in each vase, this means that each vase will contain 24 flowers

= 24 flowers

Therefore, the number of flowers needed to fill 120 vases will be:

Which equation represents exponential decay?

Answers

Answer:

The answer is C

Step-by-step explanation:

Exponential decay is when b is between 0 and 1.

Answer:

C. y = 10(0.13)^x.

Step-by-step explanation:

exponential decay is decreasing from what I remember from Algebra 1 Honors. So therefore, your only answer can be C. y = 10(0.13)^x.

The others all increase because 31, 3.1, 1.03 are all bigger than 1 which means that they increase while .13 decreases.

C. y = 10(0.13)^x.

20 points! Write an exponential function in the form y=ab^x that goes through points (0, 8) and (2, 200)

Answers

Answer:

[tex]y=8(5)^x[/tex]

Step-by-step explanation:

We want an exponential function that goes through the two points (0, 8) and (2, 200).

Since a point is (0, 8), this means that y = 8 when x = 0. Therefore:

[tex]8=a(b)^0[/tex]

Simplify:

[tex]a=8[/tex]

So we now have:

[tex]y = 8( b )^x[/tex]

Likewise, the point (2, 200) tells us that y = 200 when x = 2. Therefore:

[tex]200=8(b)^2[/tex]

Solve for b. Dividing both sides by 8 yields:

[tex]b^2=25[/tex]

Thus:

[tex]b=5[/tex]

Hence, our exponential function is:

[tex]y=8(5)^x[/tex]

Answer:

[tex]y = 8(5) {}^{x} [/tex]

Step-by-step explanation:

The normal exponential function is in form

[tex]y = ab {}^{x} [/tex]

let plug in 0,8

[tex]8 = ab {}^{0} [/tex]

b^0=1

so

[tex]8 = a \times 1 = \: \: \: \: a = 8[/tex]

So so far our equation is

[tex]y = 8b {}^{x} [/tex]

So now let plug in 2,200

[tex]200 = 8b {}^{2} [/tex]

Divide 8 by both sides and we get

[tex]25 = b {}^{2} [/tex]

[tex] \sqrt{25} [/tex]

Which equal 5 so b equal 5. So our equation is

[tex]y = 8(5) {}^{x} [/tex]

Answers

Answer:

The answer i got is 192

Step-by-step explanation:

the largest numbers shown is 8,6 and 4. When you multiply all three of them you get 192

Answer:

280

Step-by-step explanation:

Through trial and error, one can figure out that the answer is 280. Now, you might first try to go 8 * 6 * 4, which equals 192. However, if you get the product of two negative numbers, it becomes a positive, which we can use. Using the numbers -7, -5 (which cancel out each other making the product positive), and 8, the product of all of them is 280. The largest product that Khushali can make is 280.

8 * 6 * 4 = 192

(-7) * (-5) * 8 = 35 * 8 = 280
