Last Option: (-∞, 4) U (4, ∞)
Step-by-step explanation:
Domain is the set of x-values that can be inputted into function f(x).
We see that our x-values span all numbers except x = -4. Therefore, it is not included in our domain:

14.95The value of y varies directly with x. If x=8, then y=104. What is the value of x when y=195
Answers
Answer:
x = 15
Step-by-step explanation:
Use the direct variation equation, y = kx
Plug in the values of x and y to find k
y = kx
104 = k(8)
13 = k
So, the direct variation equation will be y = 13x
Plug in 195 as y to find x
y = 13x
195 = 13x
15 = x
So, x = 15 when y = 195
As The value of y varies directly with x, when y = 195, x will be 15.
What is proportion?Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
Given, The value of y varies directly with x.
∴ y = kx.
If x = 8, then y = 104.
104 = 8k.
k = 104/8.
k = 13. (constant of proportionality)
Now, y =195.
∴ 195 = 13x.
x = 195/13.
x = 15

Answers
Answer:
185/9
Step-by-step explanation:
20 5/9
Multiply 20 by the 9 (the denominator), and you''ll get 180.
Add the 5 (the numerator) to 180, and you'll get 185.
Then, place 185 over the denominator which is 9 and you get 185/9!
Answer:
[tex]\frac{185}{9}[/tex]
Step-by-step explanation:
This is the answer because:
1) The formula of changing mixed fractions to improper fractions is denominator times the whole number plus the numerator
2) Denominator = 9
Whole number = 20
Numerator = 5
9 x 20 + 5 = 185
Therefore, the answer is [tex]\frac{185}{9}[/tex]

A whippet runs 50 feet in one second. An ostrich can run at 40 mph. A giraffe runs half a mile in a minute. A domestic cat scurries 15 yards in one second. Which animal is fastest?
Answers
Answer:
Step-by-step explanation:
You need to translate these into a common rate.
feet / second is probably the best one.
Whippet: 50/1 = 50 feet / second.
Ostrich: 40 miles/ hour = 40 *[ 1 hour/3600 sec] * [5280 feet / mile] = 58.67 ft/sec
Giraffe: 1/2 mile / minute * [1 minute/60 sec]*[5280 feet/mile] = 1/2 * 5280/60 = 44 feet/second
Cat: 15 yards / sec [ 3 feet/ yard] = 45 feet / second
Looks like the Ostrich is the fastest.

The missing side length is 3x^2 + 2x -4
Step-by-step explanation:
Here, we are interested in calculating the length of the missing side.
Mathematically, the area of a rectangle = L * B
So since we have the area and one side, to get the other side, we shall need to divide the area by the side we have ;
Thus, the missing side length will be;

Y=x will be on the point of the graph
Y= x+2 will be two units up but still positive so they will never interest
Step-by-step explanation:
Hey there!!
Let's check!
The equation are:
y=x
x - y = 0......(i).
y = x+2
x - y +2 =0......(i).
From equation (i).
[tex]slope(m1) = \frac{ - coeff. \: of \: x}{ coeff. \: of \: y} [/tex]
[tex]m1 = \frac{ - 1}{ - 1} [/tex]
Therefore the slopeof 1st equation is 1.
Now,
From 2nd equation.
[tex]slope(m2) = \frac{ - coeff. \: of \: x}{coeff. \: of \: y} [/tex]
[tex]m2 = \frac{ - 1}{ - 1} [/tex]
Therefore the slope of equation 2 is 1.
As per the condition of parallel lines,
m1= m2
From both equation we got,
m1=m2=1
So, the lines are parallel.
For perpendicular,
m1×m2 = -1
1×1 is not equal to -1.
So, they are not perpendicular.
So, The answer is Option A.
