option b ......................
The equation that can be used to solve log₄(x + 4) + log₄(x - 2) = 2 is
x² + 2x - 8 = 0.
What is a logarithm?The logarithm is the opposite of the exponential function.
This indicates that the exponent to which a fixed number, base b, must be raised in order to obtain a specific number x, is represented by the logarithm of that number.
Given, log₄(x + 4) + log₄(x - 2) = 2.
We know logₐx + logₐy = logₐxy.
log₄(x + 4)(x - 2) = 2.
log₄(x² - 2x + 4x - 8) = 2.
log₄(x² + 2x - 8) = 2.

The diagram of translatation FGH 3 units down and 2 units left followed by a rotation counterclockwise 90° is attached below.
What is dilation?Dilation is the process of increasing the size of an item without affecting its form.
Depending on the scale factor, the object's size can be raised or lowered.
The translate FGH 3 units down and 2 units left followed by a rotation counterclockwise 90°.Then followed by a dilation by a scale factor of 2.
F ( -1, 0)
G (1, 0)
H ( -1, 1)
Thus, counterclockwise 90°
F' ( 0, 1)
G' (0, -1)
H' ( -1, -1)
Scale factor = 2
Then

Write the equation for a line containing the point (0,2) and a slope of -7 (y=mx+b)
Answers
2 = 0 + b, b = 2
Y = -7x + 2
Answer:
[tex]y=-\frac{7}{1}x+2[/tex]
Step-by-step explanation:
The slope of -7=
[tex]-\frac{7}{1}[/tex]
so fractional slope is
[tex]y=mx+b[/tex]
Substituting slope into a fraction,
[tex]y=-\frac{7}{1} x+b[/tex]
Point is 0,2 so substitute in x and y.
[tex]2=-\frac{7}{1} (0)+b[/tex]
Solve the equation.
[tex]b=2[/tex]
So the equation for the line is

Describe two different ways to solve 8y + 22 = 2y – 12 and tell whether the two solutions will be the same.
(written response)
Answers
First way:
—> subtract 2y and 22 from both sides to get 6y= -34
—> divide both sides to get 3y= -17
—> divide both sides by 3 to get y= -(17/3)
Second way:
—> add 12 to both sides and -8y from both sides to get -6y= 34
—> divide both sides by 2 to get -3y= 17
—> divide both sides by -3 to get y= -(17/3)
There are at least 2 other ways to solve this. This is just two ways. The solution will ALWAYS be the same if you have done it correctly. Y will always = to -(17/3)

Convert each mixed number to an improper fraction.
3 & 1/9 = 3 + 1/9
3 & 1/9 = 3*(9/9) + 1/9
3 & 1/9 = 27/9 + 1/9
3 & 1/9 = (27+1)/9
3 & 1/9 = 28/9
The car's average speed is 28/9 km per hour.
5 & 1/7 = 5 + 1/7
5 & 1/7 = 5*(7/7) + 1/7
5 & 1/7 = 35/7 + 1/7
5 & 1/7 = (35+1)/7
5 & 1/7 = 36/7
The time the car travels is 36/7 hours.
----------------------
We did the conversions so we can multiply the values easier.
Distance = Rate*Time
Distance = (28/9)*(36/7)
Distance = (28*36)/(9*7)
Distance = (4*7*9*4)/(9*7)
Distance = (4*4)/(1)
Distance = 16 kilometers

What is the slope of the line given, f(0) = -5 and f(4) = 11?
Answers
Answer:
The slope is 4.
Step-by-step explanation:
We are given that f(0)=-5 and f(4)=11.
This means that we have the two points (0, -5) and (4, 11).
So, we can use the slope formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Let (0, -5) be (x₁, y₁) and let (4, 11) be (x₂, y₂). Substitute appropriately:
[tex]m=\frac{11-(-5)}{4-0}[/tex]
Evaluate:
[tex]m=\frac{16}{4}=4[/tex]
Hence, the slope of the line given f(0)=-5 and f(4)=11 is 4.

Reflect ΔUTS over y = 2, and translate ΔU′T′S′ by the rule (x − 2, y + 0).
Translate ΔUTS by the rule (x + 0, y + 6), and reflect ΔU′T′S′ over y = 6.
Translate ΔUTS by the rule (x − 2, y + 0), and reflect ΔU′T′S′ over y = 2.
Answers
Answer:
A
Step-by-step explanation:
The set of transformations would prove ΔQRS ~ ΔUTS is A. Reflect ΔUTS over y = 2, and dilate ΔU′T′S′ by a scale factor of 2 from point S.
How does transformation of a function happens?The transformation of a function may involve any change.
Usually, these can be shift horizontally (by transforming inputs) or vertically (by transforming output), stretching (multiplying outputs or inputs) etc.
Firstly, we need the general rotation method (x,y) to (-y,x)
So; U (-4,-2) becomes U’ (2,-4)
T(-2,0) becomes T’(0,-2)
S(-2,-2) becomes S’ (2,-2)
The set of transformations would prove ΔQRS ~ ΔUTS are;
Reflect ΔUTS over y = 2, and dilate ΔU′T′S′ by a scale factor of 2 from point S.
Thus, option A is correct.

3. (Angles add up to 180)
30x + 4 + 86 = 180
30x + 90 = 180
subtract 90 from both sides
30x = 90
Now divide by 30
x = 3
Check your work ( input 3 to the equation)
30(3) + 4 + 84
90+ 90 = 180 it works :)
4. (Angles are adjacent to each other so there equal)
10x - 3 = 77
add 3 to both sides
10x = 80
divide it by 10
x = 8
Check your work ( input 8 to the equation )
10(8) -3 = 77
80 - 3 = 77
77 = 77
