The point, (-3, 2) is a solution to the following system.
y > x -2 x ≥ 1
True
OR
False
Answer:
False
Step-by-step explanation:
If you connect it, it won't make sense.
y>x - 2
Now plug it in
2 > -3 -2
2 > -5
That's true, but look at the next one
x >= 1
Plug it in
-3 >= 1
-3 isn't greater OR equal to 1, therefore it's false. I know for a fact, if one system isn't true for the point, then NONE of them are. It asked if the point was a solution to the whole system not just one. Trust me, it's false, whether you already "took the test" or not.

A customer paid $53.00 for a jacket after a 6 percent sales tax was added. What was the price of the jacket before the sales tax was added?
Show work
Answer:
$50.00
Step-by-step explanation:
Answer:
The correct answer is: 49.82
Step-by-step explanation:
First, you have to turn 6% into a decimal.
6%=0.06 (6/100)
Then, you multiply 6% by $53.00
0.06*53=3.18
Finally, you subtract the sales tax ($3.18) from the total paid ($53.00)
53-3.18=49.82

In a newspaper, it was reported that yearly robberies in Springfield were up 50%to 279 in 2012 from 2011. How many robberies were there in Springfield in 2011.
hi there! here's my answer for you...
There were 186 Springfield robberies in 2011.
hope this helped. i have included a step-by-step explanation below in case you need it. have a good one!
.
Think about what happens when you double a number.
You multiply it by 2. Since it's been doubles, we say is has had a 100% increase.
Likewise a 50% increase correlates to multiply by 1.5
Since we are trying to find the previous amount that experienced the increase, we divide by 1.5 to find the original amount because that amount*1.5 gives us 279.
Calling the original r, it is clear that 1.5r=279.
Solving for r, we find the original # of robberies to be 186.

At the annual high school carnival, Dalton sells popcorn for $4 a bag. His cost for setting up a booth is $20. Today, his goal is to make a profit of $500. How many bags of popcorn must he sell to make a profit of $500?
Hint: 500 = 4x - 20
Answer:
130=x
Step-by-step explanation: Do +20 on both sides the 20 on the left side cancels and 500 + 20= 520. Bring down the 4x. Divide 4 on both sides. 4 divided by 4 cancels. 520/4= 130. So he needs to sell 130. Give me brainliest.

Complete the missing value in the solution to the equation.
( 8)
Answer:
x=-6 if y=8
Step-by-step explanation:
First, plug in 8 for y then solve:
2x+3(8)=12
2x+24=12
Next, subtract 24 from each side:
2x+24=12
2x-24=-24
2x=-12
x=-6

What are the coordinates of the vertex of the graph y = x^2– 8x + 10?
Answer:
(4, -6)
Step-by-step explanation:
The value of y varies directly with x. If x=104, then y=78. What is the value of x when y=39?
58
58
52
52
29.25
29.25
69.3
Answer: 52
Step-by-step explanation:
Since the value of y varies directly with x, y = kx where k is a constant.
Since x=104, then y=78, we need to calculate the constant k. This will be:
y = kx
78 = 104k
k = 78/104
k = 0.75
What is the value of x when y=39?
Since y = =kx
39 = 0.75x
x = 39/0.75
x = 52

Firefighters just arrived at the Farquand building with a rescue truck. Mr. Farquand is stuck on a window ledge 44 feet directly above the top of the truck. The base of the ladder is a horizontal distance of 33 feet away from the building. Using the Pythagorean Theorem, determine how long the ladder must extend to reach Mr. Farquand.
Answer:
Step-by-step explanation:
The ladder must extend to a length of 55 feet in order to reach Mr. Farquand on the window ledge.
In this scenario, the height of the building (opposite side) is 44 feet, and the horizontal distance from the base of the ladder to the building (adjacent side) is 33 feet.
Using the Pythagorean theorem, we can calculate the length of the ladder (hypotenuse) as follows:
Ladder length² = Height² + Distance²
Ladder length² = 44² + 33²
Ladder length² = 1936 + 1089
Ladder length² = 3025
Ladder length = √3025
Ladder length = 55 feet
Therefore, the ladder must extend to a length of 55 feet in order to reach Mr. Farquand on the window ledge.

if the original quantity is 20 and the new quantity is 18, what is the percent decrease?
Answer:
The answer is 10%
Step-by-step explanation:
The percentage decrease for the quantity change from 20 to 18 will be 10%.
What is the percentage?The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that the original quantity is 20 and the new quantity is 18. The percentage decrease will be calculated as,
Percentage decrease = ( Original - decreased ) / original
Percentage decrease = ( 20 - 18 ) / 20
Percentage decrease = 2 / 20
Percentage decrease = 0.1
Percentage decrease = 0.1 x 100
Percentage decrease = 10%
Therefore, the percentage decrease for the quantity change from 20 to 18 will be 10%.
