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
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.

A, D and E
Step-by-step explanation:
A.
[tex]8 = z + 3[/tex]
Subtract 3 from both sides
[tex]8 -3 = z + 3-3[/tex]
[tex]5 = z[/tex]
[tex]z = 5[/tex]
B.
[tex]z - 1 = 6[/tex]
Add 1 to both sides
[tex]z - 1+1 = 6 + 1[/tex]
[tex]z = 7[/tex]
C.
[tex]20 = \frac{40}{z}[/tex]
Multiply through by z
[tex]z * 20 = \frac{40}{z} * z[/tex]
[tex]20z = 40[/tex]
Divide through by 20
[tex]\frac{20z}{20} = \frac{40}{20}[/tex]
[tex]z = 2[/tex]
D.
[tex]12z = 60[/tex]
Divide through by 12
[tex]z = 60/12[/tex]
[tex]z = 5[/tex]
E
[tex]12 + z = 17[/tex]
Subtract 12 from both sides
[tex]-12 + 12 + z = 17 - 12[/tex]

If Bruce waits for five years to begin paying back his loan, how much will he owe? $1,251.10 $1,310.21 $1,610.51 $1,810.71
Answers
Answer: He will owe $1610.51 .
Step-by-step explanation:

Rate of interest (r) = 10% = 0.10
Number of years (t)= 5 years
n= 1 (will pay once in a year)
Formula: [tex]A= P(1+\dfrac{r}{n})^{nt}[/tex]

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.
Here's the graph:

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
