Answer:
PLEASE MARK AS BRAINLIEST!!!
Step-by-step explanation:
ANSWER = x=5
Solve:
3x + 2 (2x-1) = 33
3x + 4x -2 = 33
Combine like terms
3x + 4x -2 = 33
7x-2=33
Add two to both the sides of the equation
7x-2 = 33
7x - 2 + 2 = 33 + 2
simplify:
7x = 35
Divide both sides of the equation by the same term:
7x = 35
7x /7 = 35/7
Simplify:
Cancel the terms that are in both the numerator and denominator
Divide the numbers
x=5
Therefore, the answer is = x=5

A spinner divided into six equal parts. It has three green parts, two purple parts, and one white part. What is the probability of spinning green twice in 2 spins
Answer:
1/4
Step-by-step explanation:
Given that :
Number of green = 3
Number of purple = 2
Number of white = 1
Probability of spinning green twice in 2 spins :
Probability = required outcome / Total possible outcomes
P(green on first spin) = 3 / 6 = 1/2
P(green on second spin) = 3/6 = 1/2
Hence, Probability of spinning green twice in 2 spins will be :
1/2 * 1/2 = 1/4

A small aircraft starts its descent from an altitude of h = 1.4 miles, 4 miles west of the runway
a. Find the cubic f(x)=ax3+bx2+cx+d on the interval [−4,0] that describes a smooth glide path for the landing.
b. The function in part (a) models the glide path of the plane. When would the plane be descending at the greatest rate?
Answer:
Step-by-step explanation:
From the question we are told that
Altitude of Height 1.4miles
4miles west
a) From the question
[tex]f(x)=ax3+bx2+cx+d[/tex] on interval (-4,0)
The descent can be expressed in [tex]\triangle _x =-4,0[/tex]
therefore initial points is (-4 , 1.4).
final co-ordinate is given by (0,0) as its landing
Mathematically solving in above cubic equation
[tex]0 = 0 + 0 + 0 + d \\[/tex]
[tex]d = 0[/tex]
[tex]1.4 = -64a + 16b -4c + d[/tex]
[tex]1 = -45.7a + 11.4b-2.9c+d[/tex]
Generally in this case Slope of tangent at point of descent is zero.assuming flight was initially straight before descent
[tex]f'(x) = 3ax^2 + 2bx+c[/tex]
[tex]f'(-4) = 48a -8b + c = 0[/tex]
[tex]f'(0) = c = 0[/tex]
Mathematically solving above equations we have
[tex]a = \frac{1}{40} \ and \ b = \frac{3}{20}[/tex]
Therefore having found a and b the Cubic equation is given as
[tex]f(x) = \frac{1}{40}x^3 + \frac{3}{20}x^2[/tex]
b)descent at its greatest rate
[tex]f(x)=\frac{1.4}{40} x^3 + \frac{129}{20} x^2[/tex]
[tex]f(x)=\frac{1.4}{40} x^3 + \frac{129}{20} x^2[/tex]

The solution of the given system of linear equations using substitution method is [tex]x = -1, y = 18[/tex].
What is substitution method?The substitution method can be defined as a way to solve a linear system algebraically. The substitution method works by substituting one y-value with the other. To solve it easily, the method involves finding the value of the x-variable in terms of the y-variable. After that, we then end up substituting the value of x-variable in the second equation. This helps us to directly find the value of the y-variable. We can now put the value of y in any of the given equations to find x.
The given system of equations are:
[tex]y + 8x = 10[/tex]..... (1)
[tex]2y - 4x = 40[/tex]..... (2)
The given value of [tex]x = - 1[/tex]. Therefore, the given value of 'x' satisfies for both the equations given.
Now using substitution method, substituting the value of 'x' in the equation(1), we will get the value of 'y'.
Therefore:
[tex]y + 8(-1) = 10[/tex]
⇒ [tex]y = 10 + 8[/tex]
⇒ [tex]y = 18[/tex]
Again, we can verify the value of 'y' by substituting the value of 'x' in equation (2).
Therefore,
[tex]2y - 4(-1) = 40[/tex]
⇒ [tex]2y = 40 - 4[/tex]
⇒ [tex]y = \frac{36}{2}[/tex]
⇒ [tex]y = 18[/tex]
Hence,
The solution of the given system of linear equations using substitution method is [tex]x = -1, y = 18[/tex].

9. Gross Margin equals $50,000, operating expenses equals $23,000, income
taxes equals $5,400 and sales is $110,000. What is the company's net income?
Answer:
$21600
Step-by-step explanation:
Net income is calculated by deducting all company expenses from its total revenue. Net income is given by the formula:
Net income = Revenue - cost of goods sold - operating expenses - tax.
But Gross margin = gross profit = Revenue - cost of goods sold. Hence:
Net income = Gross margin - operating expenses - tax.
Substituting gives:
Net income = $50000 - $23000 - $5400
Net income = $21600

From the question we are told that
area of dimension is [tex]A=36[/tex]
Generally the perimeter of rectangle is given as
[tex]x,y=36[/tex]
Given by
[tex](x,y)=2x+2y[/tex]
Mathematical solving for perimeter of rectangle
[tex]x=\frac{36}{y}[/tex]
[tex]f(y)= 2\frac{36}{2} +2y\\f(y)= \frac{72}{y} +2y[/tex]
Generally in finding minimum perimeter
[tex]f'(y)=\frac{-72}{y^2} +2=0\\[/tex]
