y=8/5x+3/5
Answer: Slope = 3.200/2.000 = 1.600
Geometric figure: Straight Line
Slope = 3.200/2.000 = 1.600
x-intercept = 3/8 = 0.37500
y-intercept = -3/5 = -0.6000
Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

When a fraction equals zero :
5.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
5y-8x+3
——————— • 5 = 0 • 5
5
Now, on the left hand side, the 5 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
5y-8x+3 = 0
Equation of a Straight Line
5.2 Solve 5y-8x+3 = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line 5y-8x+3 = 0 and calculate its properties
Graph of a Straight Line :
Calculate the Y-Intercept :
Notice that when x = 0 the value of y is -3/5 so this line "cuts" the y axis at y=-0.60000
y-intercept = -3/5 = -0.60000
Calculate the X-Intercept :
When y = 0 the value of x is 3/8 Our line therefore "cuts" the x axis at x= 0.37500
x-intercept = 3/8 = 0.37500
Calculate the Slope :
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -0.600 and for x=2.000, the value of y is 2.600. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 2.600 - (-0.600) = 3.200 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / R

Stephanie earned 8 points for every book she read over the summer. The equation y = 8x represents Stephanie's points based on the number of books she read.
Use the table and equation to complete the statements and find the number of books Stephanie read.
1. Stephanie earned 72 points. Did she read fewer than 2 books, between 2 and 5 books, between 5 and 6 books, or more than 7 books? Explain how you know.
2. The equation y = 8x gives the points, y, earned by reading x books.
Use this equation to find the number of books Stephanie read to earn 72 points. Show your work.
(here are the tables)(plz answer both and dont be greedy as * and say i d k and get pts!)
Answer: multiply 8 on all x number of books read
Step-by-step explanation:
1 is 8 because 8 × 1 is 8
2 is 16 because 8 × 2 is 16
3 is 24 because 8 × 3 is 24
4 is 32 because 8 × 4 is 32
5 is 40 because 8 × 5 is 40
6 is 48 because 8 × 6 is 48
7 is 56 because 8 × 7 is 56
8 is 64 because 8 × 8 is 64
9 is 72 because 8 × 9 is 72
10 is 80 because 8 × 10 is 80
1. If Stephanie had read fewer than 2 books, she would have earned less than 16 points.
2. Stephanie read 9 books to earn 72 points.
What is an equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
1. To determine the number of books Stephanie read, we can plug in the number of points she earned, which is 72, into the equation y = 8x and solve for x:
72 = 8x
Dividing both sides by 8, we get:
x = 9
So, Stephanie read 9 books to earn 72 points.
If Stephanie had read fewer than 2 books, she would have earned less than 16 points (since 8 points per book multiplied by 2 books is 16 points).
Similarly,
If Stephanie had read between 2 and 5 books, she would have earned between 16 and 40 points.
If Stephanie had read between 5 and 6 books, she would have earned between 40 and 48 points.
If Stephanie had read more than 7 books, she would have earned more than 56 points.
2. The given equation is as follows:
y = 8x
Substitute the value of y = 72 in the equation,
72 = 8x
Dividing both sides by 8, we get:
x = 9
Therefore, Stephanie read 9 books to earn 72 points.

A chemist creates a solution that contains the following ingredients and quantities
5 cups of potassium
5 cups of water
10 cups of sodium
10 cups of magnesium
20 cups of Silver Oxide
How much Silver oxide water and potassium would be in 1 cup of the solution
it is 17
Step-by-step explanation:
ur wecom
Answer:
2/5 cups of silver oxide
1/10 cups of water
1/10 cups of potassium
Step-by-step explanation:
5+ 5 + 10 + 10+ 20 = 50
there are 50 total cups
now we must find the number to divide 50 by to get the 1 cup that we need
50 / 50 = 1
Now that we know what to divide by to get the quantities for 1 cup of solution, time to get the quantities
there are 20 cups of Silver oxide
20 / 50 = 2/5 cups
there are 5 cups of water
5 / 50 = 1/10 cups
there are 5 cups of potassium
5 / 50 = 1/10 cups
