Answer:
Yes
Step-by-step explanation:
So we substitute the point given x=-5 and y = -3 to see if this solves both equations at the same time so
3(-5) - 9(-3) = 12 -> -15+27 = 12 -> 12 = 12 [this one works]
8(-5) - 14 (-3) = 2 -> -40 + 42 = 2 -> 2=2 [this one works also]
Since (-5,-3) is a solution to both equations, then this is a solution to this system
Answer: Yes
Step-by-step explanation:
Here
x = -5
y = -3
3x - 9y = 12
Here if you substitute x and y,
3 * (-5) - 9 * (-3)
(-15) - (-27)
=12
8x - 14y = 2
8 * (-5) - 14 * (-3)
(-40) - (-42)
= 2

P = 30x + 50y Corner that maximizes profit: (0, 6) What is the profit?
Answers
Answer:
The profit is 300.
Step-by-step explanation:
x = 0

The required profit is 300.
What is profit?Profit in Math is considered as the gain amount from any business activity.
Now the given function of profit is,
P = 30x + 50y
The Corner that maximizes profit is (0, 6)
Thus, At (0, 6) the given function is given as,
Put x = 0 and y = 6 in the given function.
P(0, 6) = 30*0 + 50*6
⇒ P(0, 6) = 0 + 300
P(0, 6) = 300
this is the required profit.
Thus, the required profit is 300.

If the sum of two numbers is 10 and the diffference is 6, find the numbers
Answers
8+2 = 10
8-2 = 6
X + y = 10
Rewrite as y = 10-x
Y - x = 6
Replace y
10-x -x = 6
Simplify:
10-2x = 6
Subtract 10 from both sides:
-2x = -4
Divide both sides by -2:
X = 2
Now replace x in the first equation:
2 + y = 10
Subtract 2 from both sides:
Y = 8
The two numbers are 8 and 2

Answer:
Step-by-step explanation:
4(X+5) = 144 (if on side measures (x+5) then P will be the 4 sides added
so adding the same value repeatedly means multiplication.
- Distribute: 4x + 20 = 144
- Inverse op. to isolate the variable minus 20 from both sides
- 4x = 124
- Divide by 4 on both sides
- 124/4 = 31
- x = 31 units

5th grade math/// In the first week of a food drive, the 5th grade collected 2 3/4 bags of canned goods. The goal is to collect 2 1/2 times as many bags in the second week. How many bags is the 5th grade hoping to collect in the second week?
Answers
The number of bags that would be collected in the second week is 6 7/8 bags.
How many bags would be collected in the second week?A mixed number is a number that is made up of an integer and a proper fraction. A proper fraction is a fraction that has a numerator that is less than the denominator. An example of a mixed number is 2 3/4.
In order to determine the number of bags that would be collected in the second week, multiply 2 3/4 by 2 1/2. Multiplication is the mathematical operation that is used to determine the product of two or more numbers.
Number of bags collected in the second week = 2 3/4 x 2 1/2
11/4 x 5/2 = 55/8 = 6 7/8 bags
