Answer:
x = 8
Step-by-step explanation:
small triangle is similar to larger one
set up a proportion: 9 = x + 4
9+12 x+4+2x
9 = x+ 4 cross-multiply: 9(3x + 4) = 21(x + 4)
21 3x + 4 27x + 36 = 21x + 84
6x + 36 = 84
6x = 48
x = 8

What is the zero? Please do not include spaces in your answer. Write your answers as a coordinate.
Answer:
(0,0)
Step-by-step explanation:
"Zero" refers to the x-intercept of the function. In this instance, the x-intercept of this function is (0,0).
solve for w
252=154-w
Answer:
w=−98
Step-by-step explanation:
Simplify both sides of the equation.
252=154−w
252=154+−w
252=−w+154
Step 2: Flip the equation.
−w+154=252
Step 3: Subtract 154 from both sides.
−w+154−154=252−154
−w=98
Step 4: Divide both sides by -1.
[tex]\frac{-w}{-1}=\frac{98}{-1}[/tex]
w=−98
Write an equation of the line with the given slope and y-intercept.
slope: -3
y-intercept: -6
Answer:
y=-3x-6
Step-by-step explanation:
Slope intercept form is y=mx+b
m is the slope (in this problem that is -3)
b is the y-intercept (in this problem that is -6)
Plug the slope and intercept you were given in and you get the equation of the line in slope intercept form
y=-3x-6

Here an easy question for points it’s a few but they easy
Answer: See explanation
Step-by-step explanation:
3.) 140 and its supplementary angle form a straight line, basically, they sum up to 180°. That angle is y
y + 140 = 180
Subtract both sides by 140
y = 40°
Seems both angles are congruent since they have the same label.
y + x + x = 180°
40 + 2x = 180
Subtract both sides by 40
2x = 140
Divide both sides by 2
x = 70°
4.) The missing angle = y
2x - 14 + 3x + 2 + y = 180
5x - 12 + y = 180
Subtract 5x from both sides
-12 + y = - 5x + 180
Add 12 to both sides
y = -5x + 180 + 12
y = -5x + 192
3x + 2 + 2x - 14 - 5x + 192 = 180
3x + 2x - 5x + 2 - 14 + 192 = 180
0 + 180 = 180
180 = 180
That's correct I guess.
5.) Missing angle = y
2x + 8 + 5x + y = 180
7x + 8 + y = 180
Subtract 7x from both sides
8 + y = -7x + 180
Subtract 8 from both sides
y = -7x + 180 - 8
y = -7x + 172
2x + 8 + 5x - 7x + 172
2x + 5x - 7x + 8 + 172 = 180
0 + 180 = 180
180 = 180
I.. think that's correct..?
6.) Missing angle = y
134 + y = 180
Subtract 134 from both sides
y = 46°
x + 46 + 22 = 180
x + 68 = 180
Subtract 68 from both sides
x = 112°

A surfboard manufacturer makes small and large surfboards. The production process has three stages: assembly, finish, and inspection. Each small surfboard requires 3 hours to assemble, 2 hours to finish, and 1 hour for inspection. Each large surfboard requires 4 hours to assemble, 3 hours to finish, and 1.5 hours for inspection. There are 140 hours available for assembly, 100 hours to finish, and 50 hours for inspection. The large surfboard makes $150 profit per board. The small surfboard makes $100 profit per board.Linear programming will be used to create the weekly production schedule.What would be a constraint for this problem if S
Answer:
z(max) = 5000
x₁ = 2
x₂ = 32
Step-by-step explanation:
Time Assemble Finish Inspection Profit
Small x₁ 3 2 1 100
Large x₂ 4 3 1,5 150
Availablity 140 100 50
Objective function:
z = 100*x₁ + 150*x₂ to maximize
Subject to:
First constraint assembly capacity 140 hours
3*x₁ + 4*x₂ ≤ 140
Second constraint finishing capacity 100 hours
2*x₁ + 3*x₂ ≤ 100
Third constraint inspection capacity 50 hours
x₁ + 1,5*x₂ ≤ 50
Model:
z = 100*x₁ + 150*x₂ to maximize
Subject to:
3*x₁ + 4*x₂ ≤ 140
2*x₁ + 3*x₂ ≤ 100
x₁ + 1,5*x₂ ≤ 50
General constraints x₁ ≥ 0 x₂ ≥ 0 and integers

If 4 units equal 12 inches, what is the value of 1 unit
Answer:
1 unit = 3 inches
Step-by-step explanation:
We are given that 4 units = 12 inches.
This can be rewritten as 4x = 12
Then to solve for x, you divide 4 on both sides
so x = 12/4
x = 3
Let me know if you have any questions
Answer:
3 inchesStep-by-step explanation:
4 units = 12 inches
1 unit = 12 ÷ 4 = 3 inches

Greg has a piece of rope 18 ft long. He wants to cut it into two pieces so that the longer piece (y) is 2 ft less than 3 times the length of the shorter piece (x).
Choose the two equations that will create our system of equations for this story problem.
A) x - y = 18
B) y = 2 - 3x
C) x + y = 18
D) y = 3x - 2
Answer:
The required equations are:
C) x + y = 18
D) y = 3x - 2
Step-by-step explanation:
Let x be the length of shorter piece and y be the length of larger piece
It is given that the total length is 18 ft which gives us our first equation
[tex]x+y = 18[/tex]
Now it is also given that
"3 times the length of the shorter piece (x)"
[tex]3x[/tex]
"2 ft less than 3 times the length of the shorter piece (x)"
[tex]3x-2[/tex]
Second equation will be:
[tex]y = 3x-2[/tex]
Hence, the required equations are:
C) x + y = 18
D) y = 3x - 2

Which of the polynomial equations cannot be solved using the quadratic formula?
Answer:
The polynomial equation that cannot be solved using the quadratic formula: Option2: [tex]x^2-2x^3-5=0[/tex]
Step-by-step explanation:
First of all we have to learn what a quadratic polynomial is.
A polynomial or equation of degree 2 is called a quadratic equation. Quadratic formula is used to solve quadratic equations.
The quadratic equation is of the form:
[tex]ax^2+bx+c = 0[/tex]
From the given options, only option 2 doesn't have degree 2 so it is not a quadratic polynomial.
Hence,
The polynomial equation that cannot be solved using the quadratic formula: Option2: [tex]x^2-2x^3-5=0[/tex]

Q1.
Edwin goes to a restaurant with some friends. Here are the meals they have:
2 fish and chips at £9.25 each
1 chicken and chips at £9.50
1 roast lamb at £10.55
4 puddings at £4.55 each.
Edwin pays for the meals with three £20 notes. How much change should Edwin
get?
Answer:
£3.25
Step-by-step explanation:
Hi there!
First, let’s add up how much they spent, which would be £56.75
If he paid with 3 £20 notes, he would have paid £60.
Now all we have to do is subtract 56.75 from 60, and we are left with
£3.25 in change.
Hope this helped!
