How to combine like terms

No because the bike order does not meet the restrictions of[tex]4c+6a \le 120 \ \text{ and } \ 4c+4a \le 100\\\\[/tex]

===================================================

Explanation:

c = number of child bikes

a = number of adult bikes

Each child bike takes 4 hours to build. This means 4c represents the total time spent building all c number of child bikes. Eg: if c = 2, then 4c = 4*2 = 8 hours is spent total building these two child bikes.

Meanwhile, each adult bike takes 6 hours to build. That means 6a represents the total time spent building these subset of bikes.

The expression 4c+6a is the total time spent building all of the bikes, child and adult.

The company has 120 hours of building time. The total time (4c+6a) cannot exceed this 120 hour ceiling.

This is how we arrive at [tex]4c+6a \le 120[/tex] which is one of the constraints or restrictions.

------------------------------

Now onto the testing side of things.

Each child bike takes 4 hours to test. That gives us 4c.

Each adult bike takes 4 hours to test. We get 4a.

4c+4a = total testing time for all of the bikes

[tex]4c+4a \le 100[/tex] is the second restriction we place, since we have at most 100 hours of testing time total. We cannot exceed this.

------------------------------

To summarize so far:

Let's see if we can build c = 20 child bikes and a = 6 adult bikes

Plug this pair of values into the first inequality

[tex]4c+6a \le 120\\\\4*20+6*6 \le 120\\\\80+36 \le 120\\\\116 \le 120[/tex]

The last inequality is true, which means the inequality [tex]4c+6a \le 120[/tex] is also true for the values c = 20 and a = 6.

So far it looks like we can build these number of bikes.

But we need to check the other inequality.

[tex]4c+4a \le 100\\\\4*20+4*6 \le 100\\\\80+24 \le 100\\\\104 \le 100\\\\[/tex]

We run into a problem. The last inequality is false, which means [tex]4c+4a \le 100[/tex] is false when c = 20 and a = 6 are plugged into it.

Meaning it is impossible to test 20 child bikes and 6 adult bikes in a week.

This is why   choice  A   is the final answer.

The solution to the system of two equations is (x,y) = (10, -25.5).

An equation is a mathematical statement that two expressions are equal. It is written in the form of an equality sign, which is a line with two dots on either side. The expressions on either side of the equality sign represent the same value. Equations are used to solve problems, compare quantities, and describe relationships between variables. In addition, equations are often used to describe physical laws and scientific theories.

To solve the system of equations, one must first isolate the variables by subtracting one of the equations from the other. Subtracting equation 1 from equation 2 results in equation 2 having x terms on one side and y terms on the other.

3x + 4y = 19
-5x - 2y = -1

--------------------------------
-2x = -20

Now, solve for x by dividing both sides by -2.

x = 10

Next, substitute x = 10 into equation 1 and solve for y.

5x + 2y = −1
5(10) + 2y = -1
50 + 2y = -1
2y = -51
y = -25.5

Therefore, the solution to the system of two equations is (x,y) = (10, -25.5).

The triangle's angle and side relationships, the triangle's angles, from smallest to greatest, would be ∠L, ∠M, ∠K.

When two triangle angles are not equal, their opposite sides' measurements are also not equal, with the longer side being opposite the larger angle.

The greatest side and angle in every triangle are on opposing sides. The smallest side and smallest angle of any triangle are in opposition to one another. The mid-sized side and mid-sized angle in every triangle are in opposition to one another.

The longest side of a triangle is located across from the largest angle. In a triangle, the longest side is located across from the one with the least angle.

The perimeter of the triangle is  40.42 cm

A right triangle's three sides are related in Euclidean geometry by the Pythagorean theorem, also known as Pythagoras' theorem. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.

The relationship between the three sides of a right-angled triangle is explained by the Pythagoras theorem, commonly known as the Pythagorean theorem. The Pythagoras theorem states that the square of a triangle's hypotenuse is equal to the sum of its other two sides' squares.

The length of the base is 9.5 cm

The total area of the triangle is 66.5 cm²

We know,

Area = (1/2)*base * height

⇒ 66.5 = (1/2)*9.5* h

⇒h = 14 cm

The height is 14 cm

By using Pythagoras theorem  

hypotenuse = √{(base)² + (height)²} = √{(9.5)² + (14)²}  = 16.92 cm

The hypotenuse is 16.92 cm

The perimeter of the triangle is height + base + hypotenuse = 14 + 9.5 + 16.92 = 40.42 cm

Answer:

the person above is correct

Step-by-step explanation:

A pair of functions that are inverses of each other include the following: B. f(x) = 4x³ + 5 and g(x) = ∛[(x - 5)/4].

In order to determine the inverse of this function f(x) = -1 - 1/5x, we would interchange both the input value (x) and output value (y) as follows:

f(x) = y = ∛(x + 3) - 5

x = ∛(y + 3) - 5

x + 5 = ∛(y + 3)

Taking the cube of both sides of the function, we have:

(x + 5)³ = y + 3

g(x) = y = (x + 5)³ - 3 (Not an inverse of f(x)).

From the second answer option, we have the following:

f(x) = y = 4x³ + 5

x = 4y³ + 5

x - 5 = 4y³

Dividing both sides of the function by 4, we have the following:

y³ = (x - 5)/4

Taking the cube root of both sides of the function, we have:

g(x) = y = ∛[(x - 5)/4] (An inverse of f(x))

a) The amount of the monthly mortgage payment is 843.86

b) The total amount of interest Ato Liku that will pay over the life of the mortgage is 104,000

c) The amount of the mortgage Ato Liku will have paid after 10 years is 101,263.20

a) To determine the amount of the monthly mortgage payment, we need to use the formula for the monthly mortgage payment (also known as the loan payment formula):

M = P [ i(1 + i)^n ] / [ (1 + i)^n - 1]

where M is the monthly mortgage payment, P is the principal (the remaining balance after the down payment), i is the monthly interest rate (12%/12 = 1%), n is the number of payments (30 years x 12 months/year = 360 payments), and ^ denotes exponentiation.

P = 250,000 x (1-.20) = 200,000

n = 30 x 12 = 360

i = 0.12/12 = 0.01

M = 200,000 [ 0.01(1 + 0.01)^360 ] / [ (1 + 0.01)^360 - 1]

M = 843.86

b) To determine the total amount of interest Ato Liku will pay over the life of the mortgage, we can subtract the original loan amount (200,000) from the total amount of the payments over the life of the loan:

total interest = total payments - original loan amount

total payments = M x n = 843.86 x 360 = 304,000

total interest = 304,000 - 200,000 = 104,000

c) To determine the amount of the mortgage Ato Liku will have paid after 10 years, we need to multiply the monthly mortgage payment by the number of payments made after 10 years.

10 years x 12 months/year = 120 months

Mortgage paid after 10 years = 843.86 x 120 = 101,263.20
