Find The Area Of The Figure

Answers

Answer 1

Answer:

12 [tex]cm^2[/tex]

Step-by-step explanation:

The area of a triangle is [tex]\frac{bh}{2}[/tex]. Here, b = 8, h = 3. So 8*3/2 = 12. The units is [tex]cm^2[/tex].

So the answer is 12 [tex]cm^2[/tex].

Answer 2

Answer:

12 cm

Step-by-step explanation:

[tex] \frac{1}{2} \times 3 \times 8 = 12[/tex]

area = 1/2 base height

Explain how you know the following system of equations has at most 2 solutions.
Solve the system algebraically. Show your work.
Solve the system by graphing.


y= 2x-1
y= x^2-9

Answers

Answer:

Step-by-step explanation:

Answer:

The said explanation is the answer.

Step-by-step explanation:

1) Graphing the first function (y = 2x-1). When the exponents of the variables are all 1, that is there are no square, cubes, etc. the equation is a line. Then it is enough to find two points to draw it. We can calculate two points assigning a number to x and calculating the corresponding number for y. For example, when x= 0 y= 2 times 0 -1 = -1. Then the line will pass from the point (0,-1). We need a second point, we can take x=1, then y = 2 times 1 -1 = 1. The line will pass from (1,1). We can mark the two points on the plane and draw the line from these two points.  

2) Graphing the second function (y = x^2-9). A quadratic equation is of the form: ax^2+bx+c= 0. We have: y= f(x) -9. Set y=0. We have the quadratic equation: x^2-9=0. Using the algebraic identity: a^2-b^2=(a+b)(a-b). We can rewrite x^2-9=0 as x^2-3^2=0: [(x+3)(x-3)=0] - [(x+3)=0,(x-3)=0] - [x= -3, x= 3]. Hence, there are two solutions for x. So we have two x-intercepts: (-3,0) and (3,0). To find the y-intercept, set x=0: [(y = (0)^2-9=0)] - [(y=-9)]. Hence the y-intercept: (0,-9)

In conclusion, this system of equations at most has two real solutions, since two points of both functions intersect each other.

Answer two questions about Equations A and B:
A. 3x– 1=7
B. 3x = 8
1) How can we get Equation B from Equation A?

Answers

Subtract 1 to both sides

An equation is formed of two equal expressions. We can get Equation B from Equation A by adding 1 to both the sides of equation A, while the solution of both the equations is 8/3.

What is an equation?

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

1.) The given equation A can be solved as shown below,

3x – 1 = 7

Add 1 to both the sides of the equation,

3x – 1 + 1 = 7 + 1

3x = 8 {∴ Equation B}

Divide both the sides of the equation by 3,

3x/3 = 8/3

x = 8/3

Thus, the solution of the equation is x=8/3.

2.) We can get Equation B from Equation A by adding 1 to both the sides of equation A, while the solution of both the equations is 8/3.

Solve the following equation for g.
Rg = m + h²g

Answers

Answer:

g=m/R-h²

Step-by-step explanation:

Move all terms to the left side and set equal to zero. Then set each factor equal to zero.

Answer:

g=m/R-h²

Step-by-step explanation:

Rg = m+h²g

Rg-h²g=m

by transposing h²g to the other side of the equation it has acquired a negative sign.

after this you factorise the left side.

g(R-h²)=m

now you divide both sides of the equation by R-h². The reason for doing so is because you're trying to single out g.

g=m/R-h²
