Answer:
Hope this help
Step-by-step explanation:
Plug in the y value found from the first equation in to the second equation in order to find the x value. In the previous example, this means the second equation becomes "x + 5(2- 3x) = 20"
Solve for x. The example equation becomes "x + 10 - 15x = 20," which is then "-14 x + 10 = 20." Subtract 10 from each side, divide by 14 and you have end up with x = -10/14, which simplifies to x = -5/7.
Plug in the x value in to the first equation to find out the y value. y = 2 - 3(-5/7) becomes 2 + 15/7, which is 29/7.

what is the inverse function of y = -3x + 8
Answer:
The inverse is -1/3 ( x-8)
Step-by-step explanation:
y = -3x + 8
Exchange x and y
x = -3y+8
Solve for y
Subtract 8 from each side
x-8 = -3y+8-8
x-8 =-3y
Divide by -3
-1/3(x-8) = -3y/-3
-1/3(x-8) =y
The inverse is -1/3 ( x-8)

Suppose you are given four statements about a number: a) It is the number 9. b) It is a prime number. c) It is an even number. d) The number is divisible by 15. Only two statements out of four are true. What is the least possible positive value for the unknown number?
Answer:
30
Step-by-step explanation:
as 9 isnt divisible by 15 or even, it cant be true. it cant be a prime number and even so thats not true either. the number must be 30 because it is divisible by 15 and even and the least possible value.

What is the solution to this system of equations? 22x + 42
Answer: 64x
Step-by-step explanation:
The sum of two consecutive whole numbers
is 35. What are the two numbers?
Answer:
1st number = 17
2nd number = 18
Step-by-step explanation:
Unknown number = x
Since they are consecutive numbers, we add 1 to each other.
=> x + x + 1 = 35
=> 2x + 1 = 35
=> 2x + 1 - 1 = 35 - 1
=> 2x = 34
=> 2x/2 = 34/2
=> x = 17
So, the first number = x = 17
=> Second number = x + 1 = 17 + 1 = 18
1st number = 17
2nd number = 18
A bag containing 15 ounces of mixed nuts contains 40% cashews. Liam adds 45 ounces of mixed nuts containing 60% cashews in the bag. What percent of the mixed nuts in the bag is cashews?
A.27
B.33
C.45
D.55
Answer:
The answer is D. 55%
40% cashews in 15 ounces = 40/100 × 15 = 600/100 = 6 ounces of cashew
60% cashew in 45 ounces = 60/100 × 45 = 2700/100 = 27 ounce of cashew
total weight of the mixed nuts = 15 + 45 = 60 ounces
total weight of cashew = 27 + 6 = 33 ounces
% of cashew in the 60 ounce bag = 33/60 × 100 = 3300/60 = 55%

Answer:
A is graph 3
B is graph 1
C is graph 2
Step-by-step explanation:
A is graph 3 because it’s says that she begins with at least a total of 80 os the y should not start at 0, instead it should, start at 80 but every time she gets a question wrong the graph keeps going down.
B is graph 2 because it States that Heath has 10 pennies to begin with so the y isnt 0 but 10 and every time she doubles it the graph only goes up.
C is graph 1 because it states that to Exeter a school fair it’s 5 bucks but each ticket cost 50 cents so it starts at 5 then keeps going up.
(I’m 100% sure of A but I’m not really sure about B and C but this is my best guess)
Find the midpoint of the line segment joining the points (-2,-3) and (-8,6)
Answer:
(-5, 1.5)
Step-by-step explanation:
If we have two points, (x₁, y₁) and (x₂, y₂), we can use the Midpoint Formula to find the midpoint of the line segment that joins those two points. The Midpoint Formula states that the midpoint of the line segment joining two points, (x₁, y₁) and (x₂, y₂), is [tex](\frac{x_{1} +x_{2} }{2} , \frac{y_{1}+y_{2} }{2})[/tex]. We know that (x₁, y₁) = (-2, -3) and (x₂, y₂) = (-8, 6) so after we substitute those values into the formula, we get:
[tex](\frac{-2+(-8)}{2},\frac{-3+6}{2})\\ = (\frac{-10}{2},\frac{3}{2})\\ =(-5,1.5)[/tex]

Sara's boss informed her she is getting a 5% raise. She currently makes $22 per hour. What is her new hourly wage?
Answer:
Her new hourly wage will be $23.10.
Step-by-step explanation:
First, let's find out how much her raise is in dollars.
0.05 x 22 = 1.10
Then, let's add that to her current wage.
1.10 + 22.00 = $23. 10
The amount of money of her new hourly wage will be $23.1 per hour.
What is the percentage?The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
Sara's boss informed her she is getting a 5% raise. She currently makes $22 per hour.
Let 'y' be the new hourly wage. Then the equation is given as,
0.05 = (x - $22) / $22
x - $22 = $1.1
x = $23.1 per hour
The amount of money of her new hourly wage will be $23.1 per hour.

Solve the equation for y.
6y + 12x = 18
A.
y = -2x + 3
B.
y = -3x + 2
C.
y = 2x – 3
D.
y = 3x - 2
Answer:
y = -2x+3
Step-by-step explanation:
6y + 12x = 18
Subtract 12x from each side
6y + 12x -12x= 18-12x
6y = -12x+18
Divide each side by 6
6y/6 = -12x/6 + 18/6
y = -2x+3

A farmer can buy two types of plant food, mix A and mix B. Each cubic yard of mix A contains 35 pounds of phosphoric acid, 15 pounds of nitrogen, and 16 pounds of potash. Each cubic yard of mix B contains 14 pounds of phosphoric acid, 18 pounds of nitrogen, and 64 pounds of potash. The minimum monthly requirements are 840 pounds of phosphoric acid, 540 pounds of nitrogen, and 768 pounds of potash. If x is the number of cubic yards of mix A used and y is the number of cubic yards of mix B used, write a system of linear inequalities that indicates appropriate restraints on x and y. Find the set of feasible solutions graphically for the amounts of mix A and mix B that can be used.
Answer:
The answer is below
Step-by-step explanation:
Given that the minimum monthly requirements are 840 pounds of phosphoric acid, hence:
35 pounds of phosphoric acid mix A + 14 pounds of phosphoric acid mix B ≥ 840 pounds of phosphoric acid
35x + 14y ≥ 840
The minimum monthly requirements are 540 pounds of nitrogen, hence:
15 pounds of nitrogen mix A + 18 pounds of nitrogen mix B ≥ 540 pounds of nitrogen
15x + 18y ≥ 540
The minimum monthly requirements are 768 pounds of potash, hence:
16 pounds of potash mix A + 64 pounds of potash mix B ≥ 768 pounds of potash
16x + 64y ≥ 768
Also, x ≥ 0 and y ≥0.
Therefore the equations are:
35x + 14y ≥ 840
15x + 18y ≥ 540
16x + 64y ≥ 768
x ≥ 0 and y ≥ 0
