Answer: x=14 y=10

Step-by-step explanation:

Answer:

to what?

Step-by-step explanation:

y = mx + b

y = mx + 100

How to find "m" or slope:

(0,100) and (20,400)

m = (y2 - y1) / (x2 - x1)

(400 - 100) / (20 - 0)

=> 300 / 20

=> 15

so

y = 15x + 100

The linear equation in slope-intercept form that the graph represents is \(y = 15x + 100\)

The slope-intercept form of an equation is expressed as:

\(y = mx + b\)

where,

m is the slope of the graph

b is the initial value or y-intercept

To find the linear equation, determine the values of the slope (m) and the y-intercept.

Slope (m) of the graph using two points on the line, \((0, 100)\) and \((5, 175)\):

\(Slope=\frac{y_2 - y_1}{x_2 - x_1}\)

Let,

\((0,100) = (x_1, y_1)\\(5, 175) = (x_2, y_2)\)

Plug on the values into the formula:

\(slope(m)= \frac{175 - 100}{5-0} \\= \frac{75}{5} \\Slope (m)= 15\)

y-intercept (b) of the linear graph:

The y-intercept is the initial value or the point at which the line intercepts the y-axis.

The line intercepts the y-axis at \(y=100\)

Therefore, y-intercept is 100

\(b = 100\)

To write the linear equation in slope-intercept form, substitute \(m = 15\) and \(b = 100\) into \(y = mx + b\)

Thus:

\(y = 15x + 100\)

The linear equation that represents the graph in slope-intercept form is \(y = 15x + 100\)

There were 8 slices in the whole pizza.

An equation means the formula that expresses the equality of two expressions by connecting them with the equals sign =.  Let us assume the number of slices in the whole pizza is "x".

Since Jim ate two slices which is 25% of the pizza, we will set up the equation:

2 = 0.25x

To solve for "x":

2 / 0.25 = x

x = 8.

Answer:

1/14

Step-by-step explanation:

Answer: x-intercept = (3,0); y-intercept = (0,7)

Step-by-step explanation:

-3y = 7x - 21

y = -7/3 x + 7 (divide both sides by -3)

y-intercept = (0,7) (y = mx + b; b is always y-intercept)

0= -7/3 x + 7 (plug in 0 for y to get x-intercept)

-7/3x = -7 (subtract 7 from both sides)

x = 3 (divide both sides by -7/3)

x-intercept = (3,0)

The linear equation in standard form is g + s + b=104, the relationship between silver to bronze medals is g = s  and the solution is g=46, s=29, b=29

(a) Since the United States won 104 gold (g), silver s, and bronze (b) medals in the 2012 Summer Olympics.

This means the sum of gold (g), silver s, and bronze (b) medals is equal to 104. Thus, the linear equation in standard form is:

g + s + b = 104

(b) Since the United States won 46 gold medals and the same number each of silver and bronze medals. This implies:

g = 46

s = b

Thus, the relationship between the number of silver to bronze medals is s = b

(c) To solve the linear equation, substitute g = 46 and s = b into the equation g + s + b = 104:

g + s + b = 104

46 + b + b = 104

46 + 2b = 104

2b = 104 -46

2b = 58

b = 58/2

b = 29

Also, s = 29        (Remember: s = b)

Thus, g = 46, s =29, b = 29

Therefore, the United States won 46 gold (g), 29 silver (s), and 29 bronze (b) medals in the 2012 Summer Olympics. Select options a., d. and e. for a., b., and c. respectively

Answer: 8:1

Step-by-step explanation:

Since there are 1000 grams in 1 kilogram, we can start by converting the 4 kg of glass to kilograms.

4 x 1000 = 4000, so this means that we have 4000 grams of glass in the bin.

So right now, the ratio of the glass in the bin to the plastic in the bin is 4000:500.

We can simplify: Start by dividing 100 from both numbers. Now, your ratio will look like this: 40:5. We can simplify even further, so divide 5 from both sides to get the ratio 8:1.

A perfect square refers to a number that is the result of multiplying an integer by itself. In this case, 6^1 is equal to 6.

However, 6 is not a perfect square because it cannot be obtained by multiplying an integer by itself. The perfect squares up to 6^1 would be 1^2 = 1 and 2^2 = 4.

Answer: 22.4402

Step-by-step explanation:

Answer:

84.4% of 23 is 19.412.

Step-by-step explanation:

Let the unknown number be x.

Now, 84.4% of x = 19.412.

∴ (84.4 ÷ 100) × x = 19.412.

By simplifying the equation,

x = (19.412 × 100) ÷ 84.4

x = 1941.2 ÷ 84.4

∴ x = 23

Thus, 84.4% of 23 is 19.412.
