Graph the following system of inequalities.
y>1/3x-2
y <-4x-2
Graph-X represents the given set of inequalities.
What is inequality?"An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions."
Given two inequalities are:
1. y > (1/3)x - 2
If we compare it with the slope-intercept form of a line, then:
Slope = 1/3, y-intercept = - 2
Therefore, the line cuts the y-axis at x = - 2.
Here, the greater than sign indicates that the graph would be shaded down.
2. y < - 4x - 2
If we compare it with the slope-intercept form of a line, then:
Slope = - 4, y-intercept = - 2
Therefore, the line cuts the y-axis at x = - 2.
Here, the less than sign indicates that the graph would be shaded up.
Therefore, Graph-X represents the given set of inequalities.

Taylor is 15 years younger than Marty. Twice Marty’s age added to three times Taylors age totals 205. What are the ages of Taylor & Marty?
Answer:
Taylor's age = x = 35 years
Marty's age = y = 50 years
Step-by-step explanation:
Let
Taylor's age = x
Marty's age = y
Taylor is 15 years younger than Marty.
x = y - 15
Twice Marty’s age added to three times Taylors age totals 205.
205 = 2y + 3x...... Equation 1
Therefore, we substitute y - 15 for x in
205 = 2y + 3x...... Equation 1
205 = 2y + 3(y - 15)
205 = 2y + 3y - 45
Collect like terms
205 + 45 = 5y
250 = 5y
y = 250/5
y = 50 years
x = y - 15
x = 50 - 15
x = 35 years
Solving for x
Therefore:
Taylor's age = x = 35 years
Marty's age = y = 50 years

Answer:
There were 7 players on the Bears
Step-by-step explanation:
Given
[tex]a = falcons[/tex]
[tex]b = bears[/tex]
We have that:
[tex]a = 11[/tex]
and also:
[tex]a = 2b - 3[/tex] --- 3 fewer than twice a
Required
Solve for b
Substitute 11 for a in [tex]a = 2b - 3[/tex]
[tex]11 = 2b - 3[/tex]
Add 3 to both sides
[tex]3+11 = 2b - 3+3[/tex]
[tex]3+11 = 2b[/tex]
[tex]14 = 2b[/tex]
Divide both sides by 2
[tex]\frac{14}{2} = \frac{2b}{2}[/tex]
[tex]7 = b[/tex]
[tex]b = 7[/tex]
Hence, there were 7 players on the Bears

Okay so I have no clue what to do on these problems lol. Can someone help explain it please? Thank you
Answer:
you use the Pythagorean theorem (a^2 +b^2 = c^2)
a^2 +17^2 = 19^2
a^2 + 289 = 361
a^2 = 72
a = (square root)72
5^2 + 13^2 = c^2
25 + 169 = c^2
194 = c^2
c= (square root)194
a^2 + 10^2 = 20^2
a^2 + 100 = 400
a^2 = 300
a = (square root) 300
5^2 + 14^2 = c^2
25 + 196 = c^2
221 = c^2
c= (square root) 221
Step-by-step explanation:
it says to leave it as it's simplest radical form, i can't put a square root on the screen, but put the number inside the radical and leave it like that.

lydia wants to purchase guitar lessons she sees a sign that gives the price is 47 guitar lessons and 11 guitar lessons write a linear equation to find the total cost c for d lessons
Answer:
c = 58x
Step-by-step explanation:
A linear equation is an equation in the form of f(x) = mx + c. Where m is the slope and c is the intercept.
Let the price of one guitar lessons be x, then 47guitars will be 47x and 11 guitar lessons will be 11x. All together will be 47x + 11x = 58x.
Thus, the total cost, c, is
