How do i Solve this?

Answers

Answer:

A=54.45

Step-by-step explanation:

You want to solve for the area in 2 parts. First I solved for the rectangle.

Area of a rectangle: A=lw

This means 9×3=27

Then I solved for the area of the triangle.

Area of a triangle: 1/2bh

This means 1/2(9×6.1)⇒1/2(54.9)=27.45

Then you add the area of the triangle and the areo of the rectangle together:

27.45+27=54.45

Answer:

. An investment account earns 2.8% simple interest.

   Since investment amount increases every year linearly, therefore, the modeled situation represents a LINEAR FUNCTION.

B). The price of a stock varies by 2.8% each week.

   Since price of the stock may increase or decrease every week, therefore, this situation can't be modeled by any function.

Therefore, the answer is NEITHER.

C). An investment account earns 2.8% compound interest, compounded monthly.

Formula to get the value of the final amount in the account is,

Final value = Initial value ×

Three students each examine the system of linear equations shown.
8x+4y=16
8x+2y=8
Caleb says there is exactly one solution. Jeremy says there is no solution. Kim says there are infinitely many solutions.

Answers

Caleb is right because there is exactly one solution at (0, 4).
Linear equation
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change and b is the initial value of y.
Given the equation:
8x + 4y = 16 (1)
8x + 2y = 8 (2)
Solving equation 1 and 2 simultaneously gives:
x = 0, y = 4
Caleb is right because there is exactly one solution at (0, 4).

Answer:

The solution is (0, 4), and there is only one solution

Step-by-step explanation:

Let's actually solve the system if that's possible.  Solving the second equation for 8x, we get 8x = 8 - 2y.  Substituting this result into the first equation eliminates y:

8 - 2y + 4y = 16,

which simplifies to 2y = 8 and then y = 4.  

Substituting 4 for y in the second equation yields 8x + 2(4) = 8, so we can quickly deduce that x = 0.

The solution is (0, 4), and there is only one solution
