Answer:
y = 7
Step-by-step explanation:
x = -16 is a vertical line.
All lines perpendicular to a vertical line are horizontal lines. All horizontal lines have a slope of 0
so m = 0, y = 7, x = -2
y = mx + b
7 = 0(-2) + b
b = 7
so,
y = 0x + 7
y = 7

The two functions appear to be symmetric about the y axis, and satisfy the equation:
[tex]g(x) = f( - x) \\ g(x) = \frac{1}{2} (3) {}^{ - x} [/tex]Answer: Option 3Solve number 3 please :)
Answer/Step-by-step explanation:
Function A has a rate of change of 10 and function B has a rate of change of 5, so function A has a greater rate of change.
y = mx + b
The slope also known as rate of change is represented as the variable m in y = mx + b. So whatever number replacing m is the rate of change. In this problem 10 is the slope or rate of change.
In a graph, rate of change is determined by the rate in which the output is increasing or decreasing compared to the increase or decrease of the input. In this graph for every 1x added 5y is decreased. So, the rate of change is 5.

SOLVE: log x - log (x+4) = -1
Answer:
x = 4/9
Step-by-step explanation:
Remember when you subtract logs, you divide the numbers;
This means;
log x - log (x+4) = -1 ---------can be written as;
[tex]log\frac{x}{x+4} =-1[/tex]
Eliminate the log as
[tex]\frac{x}{x+4} =10^{-1}[/tex]
x/ x+4 = 1/10
10x=x+4 --------collect like terms
10x-x =4
9x = 4 ------find value of x
x= 4/9

you are tiling a kitchen floor that is 10 ft wide by 4 yd long. how many square yards of tile do you need? study.com
40÷3 or [tex]13\frac{1}{3}[/tex] square yards of tiles are needed.
To find the amount of square yards of tile needed, we will find the area. Now, to calculate the area in square yards, first thing needed in conversion of width of kitchen floor from feet to yard.
As per the known fact, 1 foot = 1÷3 yards
So, converting given width into yards, we will simply multiply
10 feet = (1÷3)×10
10 feet = 10÷3 yards
Now, calculating the square yards of tile needed or area.
Needed tiles = (10÷3)×4
Performing multiplication to find the square yards of tile needed -
Needed tiles = 40÷3 or [tex]13\frac{1}{3}[/tex] square yards.
Hence 40÷3 or [tex]13\frac{1}{3}[/tex] square yards of tile is needed.

Answer:
x = 59° , y = 44°
Step-by-step explanation:
See the attached image below ,
Since the whole angle is 180° we can write it like this ,
(2x + 18)° + (x - 15)° = 180°
2x + x + 18 - 15 = 180
3x +3 = 180
3x = 177
x = 177/3
x = 59°
and now for y,
y = (x - 15)° CORRESPONDING ANGLES PROPERTY
y = x - 15
y = 59 - 15
y = 44°

This is a right triangle, so that means that the angle that is unknown is 90.
Angles:

7x - 12
90 + 60 + 7x - 12 = 180
150 - 12 + 7x = 180

You need to climb to the top of a house. You take the measurements shown. The right triangles created
by each object and its shadow are
similar. Can you use a ladder that
reaches heights of up to ? Not drawn to scale
Answer: Yes, the house is 12 m tall.
Step-by-step explanation:
Since the two triangles are similar, you can set up a proportion.
Like: [tex]\frac{x}{8.8}= \frac{1.5}{1.1}[/tex] (other proportions could be correct, as long as corresponding parts are lined up).
Solve by cross-multiplying (multiply each diagonal, then set equal).
This gives us: 1.1(x) = 8.8(1.5)
Simplify: 1.1x = 13.2
then divide both sides by 1.1 to solve for x: x = 13.2/1.1 = 12
This tells us the height of the house is 12 m. A 13 m ladder would ideally reach the top.
Kalista is making a new dance outfit. She needs 2 ½ yards of fabric for the shawl. She needs 1 ¾ yards of fabric for the dress. If she has 3 yards of fabric, how much more does she need? If each yard of fabric cost $7.98, how much money does she need?
Answer:
$9.98
Step-by-step explanation:
The first step is to calculate the total fabric that Calista has
= 2 1/2 + 1 3/4
= 5/2 + 7/4
= 17/4
The next step is to calculate the fabric that she needs
= 17/4-3
= 5/4
If each yard of fabric costs $7.98 then the amount needed can be calculated as follows
= 7.98 × 5/4
= 7.98 × 1.25
= 9.975
= $9.98
Hence Kalista needs $9.98

Therefore in each composite function we get different domains and ranges which is given below.
Function is whose values are found from 2 given operates by applying one operate to AN variable so applying the second operate to the result and whose domain consists of these values of the variable that the result yielded by the primary function lies within the domain of the secondThe domain of a operate is that the set of values that we tend to ar allowed to plug into our operate.This set is that the x values in a very operate like f(x).The vary of a operate is that the set of values that the operate assumes. This set is that the values that the operate shoots out when we tend to plug AN x price in. they're the y values out after we plug an x value in. They are the y values.(1) f(x) = x+2 , g(x) = 3x - 1
(f + g)(x) = f(x) + g(x)
= x+2 + 3x - 1
= 4x +1
Domain = (-∞ , ∞) and range = (-∞ , ∞)
(f - g )(x) = f(x) - g(x)

= -2x + 3
Domain = (-∞ , ∞) and range = (-∞ , ∞)
(f.g)(x) = f (x) g(x)
= (x+2)( 3x - 1)
= 3x²- x + 6x - 2
= 3x²+ 5x -2
Domain = (-∞ , ∞) and range = [-49/12 ,∞)

= x+2/3x-1
Domain = (-∞ , 1/3) ∪ (1/3 ,∞) and range = (-∞ , 1/3) ∪ (1/3 ,∞)
(2) f(x) = x² - 5 and g(x) = -x +8
(f + g)(x) = f(x) + g(x)
= x² - 5 -x +8
= x² - x +3
Domain = (-∞ , ∞) and range = [11/4 ,∞)

A ski resorts offers private lessons to their customers. Big time ski mountain charges $5 per hour plus $50 insurance. Powder hills charges $10 per hour plus $30 insurance. How many hours would make the cost of lessons the same for each resort?
Answer:
4 hours
Step-by-step explanation:
Big time ski mountain charges $5 per hour plus $50 insurance.
Powder hills charges $10 per hour plus $30 insurance.
Let the number of hours be x.
For big time ski mountain, it means the total cost of x hours of lesson is:
[tex]B=50+5(x)\\B=50+5x[/tex]
For powder hills , it means the total cost of x hours of lesson is:
[tex]P=30+10(x)\\P=30+10x\\[/tex]
We need to equate both equations to find the time that the costs would be the same.
That is :
[tex]50+5x=30+10x[/tex]
Collect like terms:
[tex]10x-5=50-30\\5x=20[/tex]
Divide through by 5:
[tex]x=\frac{20}{5} \\x=4 hours[/tex]
It would take 4 hours for the cost of the lessons to be the same.
