Answer:
z=28
Step-by-step explanation:
first, add one to each side to eliminate the negative one. you'll get:
7= [tex]\frac{1}{4}[/tex]z
now, to get rid of the 1/4, multiply both sides by 4.
(7x4)=(1/4z)4
simplify to get 28=z.
hope this helps!
the correct answer is z=28

x2 - 2x - 3= 0 what is the solution
Step-by-step explanation:
x^2 - 2x - 3 = 0
(x - 3)(x + 1) = 0
x = 3 (or) x = -1
7x+12 = (x+3 )+ (x+4)
Answer:
-1
Step-by-step explanation:
7x+12=(x+3)+(x+4)
7x+12=2x+7
5x+12=7
5x=-5
x=-1
Question 15 (1 point)
If (-3,1) is in the function f(x), then which of the following
points will be in the function f-'(x)?
(1, -3)
(3,-1)
(-1,3)
(-1,-3)
The point which will be in function is f-'(x) is (1, -3).
We are given that;
The point (-3,1) is in the function f(x)
Now,
Function is a type of relation, or rule, that maps one input to specific single output.
A function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.
Linear function is a function whose graph is a straight line
To find the inverse of a function, we need to switch the inputs and outputs of the function.
In other words, if f(x) = y, then f^ {-1} (y) = x.
This means that if (-3, 1) is in the function f(x), then (1, -3) will be in the function f^ {-1} (x).
Therefore, by function answer will be (1, -3).

what is the domain of this function
y= sqrt of x
Answer:
Domain: [0, ∞)
Step-by-step explanation:
Domain is the set of x-values that can be inputted into function f(x).
Our f(x) = √x
We know that we cannot have a negative under the square root. Therefore, we know that our x-values span from 0 to infinity:
[0, ∞) or x ≥ 0
Carolines hair is 7 inches long and grows up to 1/5 inch each month. Trinity's hair is 10 inches long and grows about 1/10 inch each month.
How many months will it take for Carolines hair to be atleast as long as Trinitys hair? Define the variable.
Answer:
30 months
Step-by-step explanation:
Let the number of months = x
Carolines hair is 7 inches long and grows up to 1/5 inch each month.
7 + (1/5)x
= 7 + 0.2x
Trinity's hair is 10 inches long and grows about 1/10 inch each month.
10 + (1/10)x
10 + 0.1x
How many months will it take for Carolines hair to be atleast as long as Trinitys hair?
Caroline = Trinity
7 + 0.2x = 10 + 0.1x
0.2x - 0.1x = 10 - 7
0.1x = 3
x = 3/0.1
x = 30 months
Therefore, it will take for 30 months for Caroline's hair to be atleast as long as Trinitys hair

Somebody please help!
Answer:
3x-4y
Step-by-step explanation:
You need to simplify the equation. Because you can only add numbers with same variable, add 2x and x together to get 3x. Since 3x and -4y have different variables, they can't be added together, so this is the simplest form of the equation. JUST TO BE CLEAR, you won't be able to find the exact value of the variables unless you have more information. Therefore the only thing you can do is simplify.

Given f (x) = 1/x+11, find the average rate of change of f (x) on the interval [3, 3+h]. Your answer will be an expression involving h.
The average rate of change of the function in the interval is of:
[tex]A = -\frac{1}{14(14 + h)}[/tex]
What is the average rate of change?The average rate of change of a function f(x) over an interval [a,b] is given by:
[tex]A = \frac{f(b) - f(a)}{b - a}[/tex]
In this problem:
The interval is [3, 3 + h], hence [tex]a = 3, b = 3 + h[/tex].[tex]f(3) = \frac{1}{3 + 11} = \frac{1}{14}[/tex][tex]f(3 + h) = \frac{1}{3 + h + 11} = \frac{1}{14 + h}[/tex]Then:
[tex]f(b) - f(a) = \frac{1}{14 + h} - \frac{1}{14} = \frac{14 - 14 - h}{14(14 + h)} = -\frac{h}{14(14 + h)}[/tex]
[tex]A = \frac{-\frac{h}{14(14 + h)}}{3 + h - 3} = -\frac{-\frac{h}{14(14 + h)}}{h} = -\frac{1}{14(14 + h)}[/tex]
