which system of linear inequalities Is represented by this graphed solution?
Answer:
y ≥ 3x - 1
y < [tex]-\frac{1}{2}x+2[/tex]
Step-by-step explanation:
Let the equation of the solid line passing through (x', y') given in graph is,
y = mx + b
Here m = slope of the line
b = y-intercept
Slope of the solid line =
m = [tex]\frac{3}{1}[/tex]
m = 3
y - intercept 'b' = -1
Therefore, equation of the line will be,
y = 3x - 1
Since, shaded (blue) area is above the line, inequality that will represent the solution area will be,
y ≥ 3x - 1
For the dotted line,
Slope of the line (m) = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]
= [tex]\frac{-2}{4}[/tex]
= [tex]-\frac{1}{2}[/tex]
y-intercept (b) = 2
Equation of the dotted line → y = [tex]-\frac{1}{2}x+2[/tex]
Since, shaded (grey color) area is below the dotted line,
Inequality representing the solution area will be,
y < [tex]-\frac{1}{2}x+2[/tex]

A country club bought some single golf carts that cost $7,000 each, and some double golf carts that cost $11,000 each. A
total of 24 golf carts were bought, for $228,000. How many single golf carts and how many double golf carts did the
country club buy?
Answer:
its #
Step-by-step explanation:
Answer:
9 single golf carts and 15 double golf carts.
Step-by-step explanation:
x = single golf carts and y = double golf carts
System equations:
x+y=24
7,000x+11,000y=228,000
Take the first system equation and subtract x from both sides to get
y=-x+24
Substitute the new equation into the second equation
7,000x+11,000(-x+24)=228,000
Distribute to get rid of the parenthesis
7,000x-11,000x+264,000=228,000
Combine like terms
-4,000x+264,000=228,000
Subtract
-4,000x=-36,000
Divide to get x
x=9
Substitute x into the first equation to get y
9+y=24
y=15

Alejandra is packing a bag for a flight. The airline has a baggage weight limit, and Alejandra has already packed her bag with some essentials. All she has left is her outfits and shoes, which must weigh less than 30 pounds total.
If Alejandra estimates that one outfit welghs two pounds and one pair of shoes weighs three pounds, which graph represents the number of outfits and shoes that Alejandra can pack while staying under the weight limit?
there are no pictures of a graph BUT i can give you the intercepts.
x=2
y=12
OR
x=4
y=8
OR (sorry i cant see the graph options its one of the three)
x=8
y=3
its a solid line
x are the shoes
y are the outfits
The region below the line 2x + 3y = 30 is considered and the graph is drawn.
What is inequality?Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
Alejandra is preparing her suitcase for takeoff. Alejandra has already stuffed her luggage with the necessities because the airline has a weight restriction on checked bags. She only has her clothes and shoes remaining, which together must weigh no more than 30 pounds.
If Alejandra determines that one pair of shoes weighs three pounds and one dress weighs two pounds.
Let 'x' be the number of outfits and 'y' be the number of shoes. Then the inequality is formulated as,
2x + 3y < 30
The region below the line 2x + 3y = 30 is considered and the graph is drawn.
