Answer:
{13,14}
Step-by-step explanation:
Let
x ----> number of hours per week of tutoring
y ----> number of hours per week of landscaping
we know that
She can work no more than 17 hours
so
-----> inequality A
She must earn at lest $240
The term " at least" means, "greater than or equal to"
----> inequality B
If Autumn worked 3 hours landscaping
then
substitute in the inequality A and in the inequality B
<em>Inequality A</em>
Inequality B
The solution of the system is the interval {12.75,14]
All possible values for the number of whole hours tutoring that she must work to meet her requirements are
{13,14}
I would change the fractions to decimals so that I could see least to greatest.
19/6=3.17
47/14=3.36
83/2=41.5
Least to greatest:
19/6, 47/14, 83/2
Answer:
Option 2: (1, 0) and (0, -5)
Step-by-step explanation:
Let's solve this system of equations using the elimination method.
Start by labelling the two equations.
5x -y= 5 -----(1)
5x² -y= 5 -----(2)
(2) -(1):
5x² -y -(5x -y)= 5 -5
Expand:
5x² -y -5x +y= 0
5x² -5x= 0
Factorise:
5x(x -1)= 0
5x= 0 or x -1= 0
x= 0 or x= 1
Now that we have found the x values, we can substitute them into either equations to solve for y.
Substitute into (1):
5(0) -y= 5 or 5(1) -y= 5
0 -y= 5 or -y= 5 -5
y= -5 or -y= 0
y= 0
Thus, the solutions are (0, -5) and (1, 0).
