graph each inequality y-3x<-4
First we solve the inequality for y
Add 3x on both sides, so inequality becomes
y < 3x -4
Now we graph it
for graphing , replace < symbol with = sign
y= 3x - 4
Now make a table, assume some number for x and find out y
x y
-1 y=3(-1)-4 = -7
0 y=3(0)-4 = -4
1 y=3(1)-4 = -1
Now plot (-1,-7), (0,-4) ,(1,-1) on graph
Join all the points and make a dotted line ( dotted line for < or > symbol)
now we do shading
for < symbol we shade down
for > symbol we shade up
The graph is attached below
Answer:
a. The variable X represents the amount of hot dogs
b. the variable Y represents the amount of sodas
c. Their total expense would be $13.50
If you multiply $1.50 by 7 you would get $10.50, then you would multiply $0.75 by 4 and get $3.00.
then you would add 10.50 and 3.00 to get $13.50
Answer:
They arrive at the same time.
Step-by-step explanation:
If Alison spends 3 seconds to cover the last 1/4, it means that in 12 seconds will cover the four quarters because the acceleration is constant.
On the other hand Kevin spends 4 seconds to cover the last 1/3 of the distance, it means that in 12 seconds will cover three thrds.
Finally we can conclude that both of them spend the same time to cover the drag race.
Answer:
1 : 10
Step-by-step explanation:
Answer:
The answer is $20.25.
Step-by-step explanation:
If you divide 9 by 4 first you will get 2.25 so then you multiply 2.25 by 9 you will get $20.25. Hope this is correct!
