Answer:
The slope is 2/5 (0.4).
Step-by-step explanation:
The formula for finding a slope is m = (yB - yA)/(xB - xA). That equation becomes:
m = (9 - 7)/(5 - 0)
Subtract 7 from 9 to get 2.
m = 2/(5 - 0)
Any number subtracted by 0 equals itself.
m = 2/5, or 0.4 is the final answer.

pH is a measurement of hydronium ions and can be modeled by the function f(x) = −log10x. The variable x represents the amount of hydronium ions, and f(x) gives the pH level.
Different liquids have ideal pH values that are different. Water at 25 degrees Celsius has a pH of 7. Anything that has a pH less than 7 is called acidic, and a pH above 7 is basic, or alkaline. Seawater has a pH just more than 8, whereas lemonade has a pH of approximately 3.
Create a graph of the pH function either by hand or using technology. Locate on your graph where the pH value is 0 and where it is 1. You may need to zoom in on your graph.
Use your graph to find the ideal pH level if the amount of hydronium ions is raised to 0.50.
The pool company developed new chemicals that transform the pH scale. Using the pH function f(x) = −log10x as the parent function, explain which transformation results in a y-intercept and why. You may graph by hand or using technology. Be sure to label each transformation on the graph.
f(x) + 1
f(x + 1)

Rafael earns $10.50 per hour helping his neighbor with their chores. He is curious how much money he will earn depending on the number of hours he works. Write an equation that describes the situation. Use x to represent the independent variable and y to represent the dependent variable.
PLZ HELP
Answer: y=10.50x
Step-by-step explanation:
The y in this equation represents the dependent varible which is our output what we are solving for. We know that Rafeal gets $10.50 per hour but we don't know how many hours he works so to represent the time we use the variable x. If we were to solve this we would take the hours that he worked and multiplied the number of hours by $10.50 to get y the cost which he earns.
The equation that represents the given statement will be equal to y = 10.50(x) and y is the dependent variable.
What is an equation?Mathematical expressions with two algebraic symbols on either side of the equal (=) sign are called equations.
This relationship is illustrated by the left and right expressions being equal to one another. The left-hand side equals the right-hand side is a basic, straightforward equation.
As per the data mentioned in the question,
Earning made by Rafael per hour = $10.50
Let the number of hours working is x.
Then, the equation that represents the given statement,
y = 10.50(x)
Here, y is the total money earned by Rafael.

The organizers of a concert are preparing for the arrival of 50,000 people in a field. Each person is alloted 5 square ft of space, so the
organizers rope off a circular area big enough to account for 5 square feet per person. Find the radius of this region, rounding to the nearest
foot.
Answer:
Radius of park r = 282.04 ft (Approx)
Step-by-step explanation:
Given:
Number of people = 50,000
Each person needs area = 5 ft²
Park's is in shape of circle
Find:
Radius of park r
Computation:
Total area required = 50,000 x 5
Total area required = 250,000 ft²
Area of circular park = Total area required
πr² = 250,000
(22/7)r² = 250,000
r² = 79545.4545
r = 282.04 ft
Radius of park r = 282.04 ft (Approx)

Rearrange this formula to make x the subject.
y = 3x2 - 2
Answer:
The subject 'x' in terms of 'y'
[tex]x = \sqrt{\frac{y+2}{3} }[/tex]
Step-by-step explanation:
Explanation:-
Given subject in terms of 'x'
y = 3 x² - 2
Adding '2' on both sides, we get
y + 2 = 3 x² - 2 +2
y+2 = 3 x²
Dividing '3' on both sides, we get
[tex]x^{2} = \frac{y+2}{3}[/tex]
[tex]x = \sqrt{\frac{y+2}{3} }[/tex]
The areas of the squares adjacent to two sides of a right triangle are shown below.
? units?
35 units
50 units
What is the area of the square adjacent to the third side of the triangle?
Answer:
85
Step-by-step explanation:
All you do is add 35 units and 50 units together.
Area of the square adjacent to the third side of the triangle is 85 units square
What is Pythagoras theorem?Pythagoras theorem states that a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.
Given that areas of the squares adjacent to two sides of a right triangle are :
35 sq units
50 sq units
To determine the area of the square adjacent to the third side of the triangle
According to Pythagoras theorem,
Hypotenuse² = Base² + Perpendicular²
As figure is missing assuming given sides are perpendicular sides
Then Area of the square adjacent to the third side of the triangle = 35 + 50
= 85 units square
Now, assuming 50 sq unit is an area on hypotenuse
Then Area of the square adjacent to the third side of the triangle = 35 - 50
= 15 units square

4(x/8 - 2) = 1/4(2x - 1/2) is the complete equations for having infinitely many solutions.
What are simultaneous equations?We know two simultaneous equations have a unique solution when they intersect at a point,
when they are parallel they have no solution and when they are coinciding they have an infinite no. of solutions.
Given, 4( x/8 - 2) = 1/4(2x -___.
(1/2)x - 8 = (1/8)x - ___.

The owner of a small store buys coats for $60.00 each. Answer parts a and b.
a. She sells the coats for $72.00 each. What percent of the purchase price is the sale price?
The sale price is
% of the purchase price.
The percent of the purchase price would be 20% of the sale price.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
First we need to calculate the difference between the purchase and sale price.
$72.00 - $60.00 = $12.00
Since $12 is the increase in dollars.
To increase as a percentage we need to divide the increase by the original purchase price.
12.00 ÷ 60.00 = 0.2
This simply means moving the decimal place two columns to the right;
0.2 x 100 = 20
Therefore, the percent of the purchase price would be 20% of the sale price.
