Solve the following equation. Write your answer in reduced fraction form, if necessary. (7x−2)(x+6)=0
Answer:
x = 2/7
x = -6
Step-by-step explanation:
You can solve the equation by setting each set of parentheses equal to 0 and simplifying.
7x - 2 = 0 <----- First set of parentheses
7x = 2 <----- Add 2 to both sides
x = 2/7 <----- Divide both sides by 7
x + 6 = 0 <----- Second set of parentheses
x = -6 <----- Subtract 6 from both sides

2. Write the rule for the linear function. Remember a function rule is written using f(x).
Answer:
[tex]f(x) = \frac{1}{2}x + 5[/tex]
Step-by-step explanation:
So you can generally express a linear function use the slope-intercept form as such: [tex]y=mx+b[/tex] where m=slope, and b=y-intercept.
The y-intercept is defined as the value of f(0), since when the line crosses the y-axis, the x-value is 0, and as provided in the table that value is 5, so we have the function rule: [tex]f(x) = mx+5[/tex]
The slope is defined as how much y-changes, as x increases by 1. We can generally use the formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] and this can be found using any two points, since the slope is constant.
We can use the two points (0, 5) and (2, 6) and plug it into the equation, to find the rise/run
[tex]\frac{6-5}{2-0} = \frac{1}{2}[/tex]
So plugging this into the slope-intercept form you get the function
[tex]f(x) = \frac{1}{2}x + 5[/tex]

Which logarithmic equation is equivalent to 82 = 64?
2 = log Subscript 6 Baseline 64
2 = log Subscript 64 Baseline 8
8 = log Subscript 2 Baseline 64
64 = log Subscript 2 Baseline 8
Answer: Choice B
[tex]2 = \log_{8}(64)[/tex]
======================================================
Explanation:
The original equation is [tex]8^2 = 64[/tex] with 8 as the base. That is also the base of the log when we get the final answer shown above. Logs are useful to isolate the exponent.
The general rule is that [tex]\text{y} = b^{\text{x}}[/tex] is equivalent to the log form of [tex]\text{x} = \log_{b}(\text{y})[/tex] where b is the base of each.
2 = log Subscript 64 Baseline 8 is the logarithmic equation which is equivalent to 82 = 64.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
A logarithmic equation is an equation that involves the logarithm of an expression containing a variable.
The logarithmic equation equivalent to 82 = 64 is:
2 = log Subscript 64 Baseline 8
This is because the logarithmic equation relates the base (64) to the result of the exponentiation (8), which in this case is 2.
Hence, 2 = log Subscript 64 Baseline 8 is the logarithmic equation which is equivalent to 82 = 64.

You deposit $2000 each year into an account earning 7% interest compounded annually. How much will you have in the account in 30 years?
The amount that will be in the account after 30 years is $188,921.57.
How much would be in the account after 30 years?When an amount is compounded annually, it means that once a year, the amount invested and the interest already accrued increases in value. Compound interest leads to a higher value of deposit when compared with simple interest, where only the amount deposited increases in value once a year.
The formula that can be used to determine the future value of the deposit in 30 years is : annuity factor x yearly deposit
Annuity factor = {[(1+r)^n] - 1} / r

A circle is a figure bounded by a curved side which is referred to as circumference. Thus the area of the shaded region is option D. 81.65.
A circle is a figure bounded by a curved side which is referred to as circumference. Some of its parts are radius, diameter, sector, arc, etc.
The area of a circle can be determined by the given expression:
Area = π[tex]r^{2}[/tex]
where r is the radius of the circle and π = [tex]\frac{22}{7}[/tex]
So, the area of the shaded region can be determined as:
Area of the shaded region = area of the larger circle - area of the smaller circle
Area of the shaded region = π[tex](6.8)^{2}[/tex] - π[tex](4.5)^{2}[/tex]
= π (46.24 - 20.25)
= [tex]\frac{22}{7}[/tex] x 25.99
= [tex]\frac{571.78}{7}[/tex]
Area of the shaded region = 81.683

What is linear equation?
An equation in which the highest power of the variable is one is known as linear equation.
We will find number of pizza slices as shown below:
Let pizza originally have x slices.
Adam eats 20% of a pizza
= 0.2x
Bethany eats 1/3 of pizza
=1/3(x)
Charlie eats the remaining 14 slices
0.2x+1/3(x)+14=x
14 = x - 0.2x - 1/3(x)
14 = x - x/5 - x/3
14 = (15x - 3x - 5x)/15
14*15 = 7x

c 6x + y= 12 and 5x +8y =-100
From the given system of linear equations, we have;
a. x ≈ 0.697, y ≈ 5.84b. x ≈ 2.48, y ≈ -1.82c. x ≈ 4.56, y ≈ -15.35How can technology be used to solve the given equations?a. The system of linear equations can be expressed as follows;
y = 22•x - 9.5
y = 2.5•x + 4.1
Rewriting the equations to have the constants on the right, we have;
y - 22•x = - 9.5
y - 2.5•x = 4.1
Solving the above equations using matrices method on a calculator gives;
y = 5.84x = 0.697By direct solving, we have;
22•x - 9.5 = 2.5•x + 4.1
22•x - 2.5•x = 4.1 + 9.5
19.5•x = 13.6
x = 13.6 ÷ 19.5 ≈ 0.697
x ≈ 0.697y = 22•x - 9.5
y = 22×(13.6/19.5) - 9.5 ≈ 5.84
y ≈ 5.84b. 8•x + y - 18 = 0
5•x + 9•y + 4 = 0
Rewriting gives;
8•x + y = 18
5•x + 9•y = -4
Solving with technology gives,;
x ≈ 2.48y ≈ -1.82Solving directly gives;
y = 18 - 8•xy = -(5•x + 4)/9Which gives;
18 - 8•x = -(5•x + 4)/9
9×(18 - 8•x) = -(5•x + 4)
162 - 72•x = -(5•x + 4)
5•x - 72•x = -162 - 4 = -166
67•x = 166
x = 166 ÷ 67 ≈ 2.478
x ≈ 2.478y = 18 - 8•x
Therefore;
y = 18 - 8 × (166 ÷ 67) ≈ -1.82
y ≈ -1.82c. 6•x + y = 12
5•x + 8•y = -100
Solving the above linear system using technology, we have;
x ≈ 4.56y ≈ -15.35Solving directly, we have;
y = 12 - 6•x
5•x + 8•y = -100
y = (-100 - 5•x)/8
12 - 6•x = (-100 - 5•x)/8
8 × (12 - 6•x) = (-100 - 5•x)
96 - 48•x = (-100 - 5•x)
48•x - 5•x = 96 + 100
43•x = 196
x = 196/43 ≈ 4.56

A boat travels 50 miles downstream in 2 hours and it takes 5 hours to travel back upstream. What is the speed of the boat if it were in still water and what is the speed of the river current?
The 50 mile distance traveled downstream and back that takes 2 hours and 5 hours respectively gives;
The speed of the boat in still water = 17.5 mphThe river current flows at 7.5 mphHow can the boat speed be calculated?Let v represent the speed of the boat and let u represent the speed of the river current.
Distance the boat travels downstream = 50 miles
Time taken to travel downstream by the boat = 2 hours
Time taken to travel back upstream = 5 hours
[tex]velocity = \frac{distance}{time} [/tex]
Therefore;
Which gives;
[tex]v + u = \frac{50}{2} = 25...(1)[/tex]
v + u = 25[tex]v - u = \frac{50}{5} = 10...(2)[/tex]
v - u = 10Adding equation (1) to equation (2) gives;
(v + u) + (v - u) = 2•v = 25 + 10 = 35
2•v = 35
v = 35 ÷ 2 = 17.5
The speed of the boat, v = 17.5 mphu = 25 - v
Which gives;
u = 25 - 17.5 = 7.5
The speed of the river current, u = 7.5 mph (downstream)Learn more about equations of motion here:
