Answer:

[tex]y = 1164x + 14242[/tex]

Step-by-step explanation:

From the question, we understand that

x = 0, when year = 1980

First, we need to determine the slope of the table.

Pick any two corresponding values of year and average salary

year = 1982, average salary = 16570

year = 2002, average salary = 39850

Convert years to x values

year = 1982 implies that x = 2 i.e. 1982 - 1980

year = 2002 implies that x = 22 i.e. 2002 - 198-

So, we have:

[tex](x_1,y_1) = (2,16570)[/tex]

[tex](x_2,y_2) = (22,39850)[/tex]

Determine the slope.

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

[tex]m = \frac{39850 -16570}{22 - 2}[/tex]

[tex]m = \frac{23280}{20}[/tex]

[tex]m = 1164[/tex]

The equation is calculated using:

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

Where

[tex]m = 1164[/tex]

[tex](x_1,y_1) = (2,16570)[/tex]

So,

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

[tex]y - 16570 = 1164(x - 2)[/tex]

[tex]y - 16570 = 1164x - 1164*2[/tex]

[tex]y - 16570 = 1164x - 2328[/tex]

Add 16570 to both sides

[tex]y - 16570 + 16570 = 1164x - 2328 + 16570[/tex]

[tex]y = 1164x - 2328 + 16570[/tex]

[tex]y = 1164x + 14242[/tex]

Answer:

y = 1164x + 14,242

Answer: 6.6kg

Step-by-step explanation:

6 blue slabs have a mean weight of 7 kg. The total weight of the 6 blue slabs will be:

= 6 × 7kg

= 42 kg

3 yellow slabs have a mean weight of 5 kg. The total weight of the 3 yellow slabs will be:

= 3 × 5kg

= 15kg

1 grey slab has a mean weight of 9kg.

To get the mean of the 10 slabs, we add their total weights together and divide by 10. This will be:

= (42kg + 15kg + 9kg)/10

= 66kg/10

= 6.6kg

Based on the information given the mean of 10 slabs is 6.6 kg.

Formulate

(9+5×3+6×7)/10

Calculate the quotient

9+15+6×7/10

9+15+42/10

Calculate the sum or difference

24+42/10

66/10

Reduce the fraction

33/5

Hence:

Mean=6.6 kg

Inconclusion  the mean of 10 slabs is 6.6 kg.

Answer:

y = 1/3x - 4

Step-by-step explanation:

the line crosses the y-axis at -4

To calculate the gradient of a straight line we choose two points on the line itself. From these two points we calculate: The difference in height (y co-ordinates) ÷ The difference in width (x co-ordinates)

If we take the points (9,-1) and (6,-2), we do:

-1-(-2) = 1

9-6=3

which gives 1/3

Answer:

y = 1/3x - 4

Y- intercept = -4

Slope = 1/3

Step-by-step explanation:

Y intercept is where the line intercepts/passes through the y axis

Slope is how many units it takes HORIZONTALLY (side to side) to go up ONE unit VERTICALLY (up down)

It took the line 3 horizontal units to go up 1 vertical unit. So you divide 1 by 3 which gives you 1/3

Answer:

Property Used is Division Property of Equality

Step-by-step explanation:

We need to define the property used in solving 5(x + 3) = 35, then x + 3 = 7

The Division Property of Equality states that when we divide both sides of an equation by same non-zero number  the two sides remain equal

So, in given question:

5(x+3)=35

Dividing both sides by 5 (Division Property of Equality)

5(x+3)/5=35/5

x+3=7

So, Property Used is Division Property of Equality

Answer:

Step-by-step explanation:

y=mx+b

your m is the slope and your b is the y-intercept

so for y=5x-3 your slope would be 5 and your y-intercept would be -3

The equation y = 5x - 3 represents a line with a slope of 5 and a y-intercept of -3.

The equation of a graph can be expressed as y = mx + b, which is in the slope-intercept form. This means that:

m is the slope

b is the y-intercept of the graph.

The line described by the equation y = 5x - 3 has a slope of 5, meaning that as x increases by 1, y increases by 5. The y-intercept, represented by the constant term -3, indicates that the line intersects the y-axis at the point (0, -3).

Answer:

x>7

Step-by-step explanation:

x-3>4

Add 3 to both sides

x>7

Hope it helped!

Answer:

x>7

Step-by-step explanation:

To solve the inequality you need to isolate the variable. To do so add 3 to both sides of the equation, x-3+3>4+3, which simplifies to x>7. This means any number greater than but not equivalent to 7 is a solution. So 8 or 100 would work but 7, 2, or -2 would not.

Step-by-step explanation:

The number of ham subs sold is given by the proportion equation A = 81

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

The proportional equation is given as y ∝ x

And , y = kx where k is the proportionality constant

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Given data ,

Let the number of ham subs sold be represented as A

Now , the proportion will be

The ratio of ham subs sold to cheese subs sold = 9 : 4

And , the number of cheese subs sold = 36

Substituting the values in the equation , we get

number of ham subs sold A / number of cheese subs sold = 9 / 4

On simplifying the equation , we get

A / 36 = 9 / 4

Multiply by 36 on both sides of the equation , we get

A = ( 9 x 36 ) / 4

A = 9 x 9

A = 81 ham subs

Therefore , the value of A is 81 ham subs

Hence , the number of ham subs sold is 81
