A student has started a lawn care business. He charges $15 per hour to mow lawns and $20 per hour for gardening. Because he is still in school, he is only allowed to work for at most 20 hours per week. His goal is to make at least $300 per week.
a.)Create a system of equations or inequalities that models the situation. Define the variables you use.
B.)The graph shows one of the relevant equations in this situation. Draw the graph of the other relevant equation on the same coordinate plane.
c.)Use the graph above to show all the points that represent the number of hours the student can work at each job and meet his goal. Explain your reasoning.

Jude has 30 coins of quarters and nickels. The total amount he has is $5.10. How many of each coin does Jude have? Write the system. Write the equations in the order that they appear in the problem.
Answers
Answer: Required system
x+y= 30
0.25x+0.05y=5.10
Jude has 18 quarters and 12 nickels.
Step-by-step explanation:
Let x= Number of quarters
y= Number of nickels
As per given,
x+y= 30 (i)
0.25x+0.05y=5.10 (ii) [1 quarter = $0.25 , 1 nickel = $0.05]
Multiply 0.25 on both sides of equation (i)
0.25x+0.25y= 7.5 (iii)
Eliminate (ii) from (iii) , we get
0.20y=2.4
⇒ y = 12 [divide both sides by 0.20]
Put value of y in (i\), we get
x+12=30
⇒ x= 30-12= 18
Hence, Jude has 18 quarters and 12 nickels.
9x+7y=7 find the slope
Answers
Answer:
-9/7
Step-by-step explanation:
Put the equation into y = mx + b form, by first isolating y:
9x + 7y= 7
7y = -9x + 7
Divide each side by 7:
y = -9/7x + 1
So, -9/7 is the slope.
Question 1
Equation (1) y = x + 6
Equation (2) y = 2x + 4
Equation (3) y = 3x + 2
Equation (4) y = 5x – 4
The table above shows four equations. If x = 2, which equation has a y-value different from the other three equations?
Answers
equation 2 = 8
equation 3 = 8
equation 4 = 6
so it’s 4 :)

An employee is walking home from work and wants to take the long way to get more exercise. The diagram represents the two
different routes, where A is the employee's work and B is the employee's home. Which route is longer and by how much? will mark brainliest
Answers
Answer:
The route from A to the corner to B is longer then going directly from A to B. It is roughly 1.6 miles longer.
Step-by-step explanation:
The distance from A to the corner to B is 5.9 miles because
[tex]3.8 + 2.1 = 5.9[/tex]
Going directly from A to B is roughly 4.3 miles because of
[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]
[tex]5.9 - 4.3 = 1.6[/tex]
Answer:
Walking to the right and downwards to reach B from A.
Approximately [tex]1.6[/tex] miles.
Step-by-step explanation:
Route 1 - Walking to the right and downwards to reach B from A:
The distance is [tex]2.1+3.8=5.9[/tex] miles
Route 2 - Walking straight to B from A:
[tex]\sqrt{3.8^2+2.1^2} = \sqrt{14.44+4.41}[/tex] (using the Pythagorean theorem, the two lengths are perpendicular)
[tex]=\sqrt{18.85}[/tex]
[tex]=4.341658669[/tex] miles (approximately from calculator)
Since [tex]5.9[/tex] miles is greater than [tex]4.341658669[/tex] miles, therefore walking to the right and downwards to reach home from work is the longest distance.
Difference in distance:
[tex]5.9-4.341658669=1.558341331[/tex] miles
Route 1 is longer than route 2 by [tex]1.558341331[/tex] miles, or approximately [tex]1.6[/tex] miles.
