Answer:

y=6-5

Step-by-step explanationy

Answer: U is the change in PE, m is the mass raised through a distance h. So, given m = 61.2 kg, each 1 m rise is an increase of (61.2)(9.8) = 600 J. Likewise, each floor (2.5 m) represents a change in PE of 1500 J for this mass.

Answer:

the price of the pair of shoes are $57.60

Step-by-step explanation:

So you first need to find out what 10% is in $64 so your going to multiply 0.1 (10% in decimal form is 0.1 ) by 64 to get 10% of the original price.

64 * 0.1 = $6.40

so now we are going to subtract $6.40 from $64 for the sale price:

$64.00 - $6.40 = $57.60

so the sale price is $57.60

Answer:

The interest Jacob earns after 6 years is $8.82

Step-by-step explanation:

The given parameters are;

The simple interest rate of the savings account, R = 1%

The principal deposit to the savings account, P = $147

The time duration Jacob saved the money, T = 6 years

The formula for simple interest, I, is given as follows;

[tex]I = \dfrac{P \times R \times T}{100}[/tex]

Substituting the known values gives;

[tex]I = \dfrac{147 \times 1 \times 6}{100} = 8.82[/tex]

The interest Jacob earns after 6 years = $8.82.

Answer:

Option (B)

Step-by-step explanation:

Let the equation of the line is,

y = mx + b

Here m = slope of the line

b = y-intercept

Slope of the line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,

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

Slope of the line which passes through the points (1, 1) and (-4, 7) will be,

m = [tex]\frac{7-1}{-4-1}[/tex]

   = [tex]-\frac{6}{5}[/tex]

By substituting the value of m in the equation,

y = [tex]-\frac{6}{5}x+b[/tex]

Since, this line passes through (1, 1),

1 = [tex]-\frac{6}{5}(1)+b[/tex]

b = [tex]1+\frac{6}{5}[/tex]

  = [tex]\frac{11}{5}[/tex]

Therefore, equation will be,

[tex]y=-\frac{6}{5}x+\frac{11}{5}[/tex]

5y = -6x + 11

6x + 5y = 11

Option B is the answer.

Step-by-step explanation:

the most common measure of how much sample mean differ from each other is the standard deviation of the sampling distribution of the mean. this standard deviation is called the standard error of the mean

Answer:

x² + 12

48m²

Step-by-step explanation:

Find the diagram attached.

The room can be segregated into two rectangles

The area of the room = Area of bottom rectangle + area of the top rectangle

Area of the bottom rectangle = x * (x-3) = x² - 3x

Area of the top rectangle = 3* (4+x) = 12 + 3x

The area of the room = x² - 3x + 12 + 3x

Area of the room = x² + 12

Hence the algebraic expression that the architect can use to find the area of the room is x² + 12

Given x = 6m

The area of the room = x² + 12

The area of the room = 6² + 12

The area of the room = 36 + 12

The area of the room = 48m²

Answer:

1. true 2. true 3. false 4. false 5. false

15 + 15 + 10 + 10 + 10 = 60/5 = 12 ( CODE WORD)

Step-by-step explanation:

1. There are different forms of linear equations. Slope intercept has it's equation y = mx + b

2. A proportional relationship has a constant rate of change.

ex: y =2x +5, then the rate of change is 2 and it only ever rises by 2.

3. A proportional relationship must pass through the origin in order to be a proportional relationship.

4. The variable M in slope-intercept form represents the slope. B represents the Y-intercept.

5. Standard form for a linear equation is Ax+By=C. Y = MX+B is slope-intercept form.

CODE WORD: 12 or Twelve is correct because 12 is the mean of all 5 answers.

Answer:

y=3/2x-8

Step-by-step explanation:

Step 1: Begin by distributing the 3/2 to the parentheses. This would result with 3/2x-6.

Step 2: Subtract both sides by 2 to isolate the variable, y. This would result with y=3/2x-8.

Answer:

I don't think it's possible for this to be a decimal because the slope is positive 11.

Step-by-step explanation:

Use slope formula. x2-x1/y2-y1. Since we always go with the smaller x value we do 8-(-3) / 4-3/ We'll get 11 for 8-(-3) and we'll get 1 for 4-3/ so that leaves us with 11/1 which can't be simplified and has no decimal.

Answer:

Yes, because the x's do not have more than one y.

Step-by-step explanation:

x      y

0      0

5       10

6       12

10     20

(That's meant to be a table). Looking at the x and y table values, you can see that none of the x's have two y's. So, this relation is a function.

Answer:

x - intercept = 5

y- intercept = 2

Step-by-step explanation:

2x + 5y = 10

Write the equation in   [tex]\frac{x}{a}+\frac{y}{b}=1[/tex]  form

So, divide the equation by 10

[tex]\frac{2x}{10}+\frac{5y}{10}=\frac{10}{10}\\\\\frac{x}{5}+\frac{y}{2}=1[/tex]

x - intercept = 5

y- intercept = 2

Answer:

(5,0) and (0,2)

Step-by-step explanation:

Basically, all we need to do is enter 0 for both variables. We can do this because the y-value of an x-intercept will always be 0, and the x-value of a y-intercept will always be 0.

So, to find the x-intercept we can set y equal to 0 and then solve for x.

[tex]2x+5(0)=10\\2x=10\\x=5[/tex]

So the x-intercept will be (5,0).

We can do the same thing to find the y-intercept.

[tex]2(0)+5y=10\\5y=10\\y=2[/tex]

The y-intercept is (0,2)

Answer:

16.64 m

Step-by-step explanation:

Subtract the depth of the water from the height of the tank (0.6) and use this measurement for height instead. then calculate l•h•2+w•h•2+l•w

(we multiplied the length and height and the width and height by two since there’s two sides with the same measurement for each)
