Explanation:The equation: 4x + 3y = -12
To plot the graph using the intercept, we need to find the y and x intercept
To get the y intercept, we replace x with 0
4(0) + 3y = -12
0 + 3y = -12
3y = -12
divide both sides by 3:
3y/3 = -12/3
y = -4
To get the x intercept, we will replace y with 0
4x + 3(0) = -12
4x + 0 = -12
4x = -12
divide both sides by 4:
4x/4 = -12/4
x = -3
Plotting the x and y intercept on the graph:
Answer:
250 students
Step-by-step explanation:
Another way of saying this is:
40% of all six-grade students are 100 of them.
So,
40% of total is equal to 100
We can translate this into an algebraic equation and solve for the total number of students.
Let total number of students be "t"
Also, note "of" means "multiplication" and "is" means "equal"
Lets translate word equation to algebraic:
<em>"40% of total is equal to 100"</em>
40% * t = 100
Converting percentage to decimal by dividing by 100, we have:
40% = 40/100 = 0.4
Now, we have:
0.4 * t = 100
We can now solve for t:
Hence,
the total number of students is 250
