Answer:
(-7,4]
Step-by-step explanation:
I'm going to assume that you need this in interval form
The domain is just asking for all the possible x values
The x value that's furthest to the left is -7 and because it's an open circle we write ( instead of [
the furthest to the right the line goes is 4 and because the circle is closed it's written with ]
but it all together and get
(-7,4]

Cubic Function
Step-by-step explanation:
In mathematics, a cubic function is a function of the form f(x)=ax^3+bx^2+cx+d where the coefficients a, b, c, and d are real numbers, and the variable x takes real values, and a ≠ 0. In other words, it is both a polynomial function of degree three, and a real function.
What is the value for x and for y?
Answers
Answer:
20+7x=90
x=10
50+2y=90
y=20
X=10
Y=20
Because a straight line is 180. So 180-20=160 from there you see that one of the angles is a right angle, you can tell this by that it has that little cube in the middle. So 160-90=70 that means that 7x=70 bit you are trying to find for x so divid 70 by 7 that equals 10.
Now to solve for why you have to plug in the information you already know. Vertical angles are congruent. That means that the that the 20 goes straight across and 7x with is actually 70 goes straight across. Now you already know the angle in the middle is 90 but this this it’s split. Since x is 10 multiply 5 by 10 then you get 50 now 90-50=40. 2y is 40 divide it by 2 to get y=20.
I’m bad at explaining so I hope I didn’t confuse you.

A hair stylist has three colors of hair dye. She has 4 bottles of chestnut, 7 bottles of blond, and 8 bottles of cherry. What does the ratio 8:19 represent in this situation? Explain your reasoning. Include a model in your explanation.
Answers
Answer:
The 8:19 ratio is the bottles of cherry to the total amounts of bottles
Step-by-step explanation:
im not sure what a model would look like but here's one part of the question
The ratio 8 : 19 will represent the ratio of total number of cherry bottles to the total number of bottles.
What is ratio?Ratio is the quantitative relation between two amounts showing the number of times one value contains or is contained within the other.In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is that a hair stylist has three colors of hair dye. She has 4 bottles of chestnut, 7 bottles of blond, and 8 bottles of cherry.
Total number of bottles = 8 + 7 + 4 = 19
Total number of cherry bottles = 8
The ratio 8 : 19 will represent the ratio of total number of cherry bottles to the total number of bottles.
Therefore, the ratio 8 : 19 will represent the ratio of total number of cherry bottles to the total number of bottles.

Step-by-step explanation:
a) t + 11 = 4
t = -7
b) f = 8+4
f = 12
c) 5 = 18 + k
-13 = k
Answer:
A= -7
B= 12
C= -13
Step-by-step explanation:
This is how I do it
A) Subtract 4 from each side, and when you do that you get 7=-t which makes the answer -7.
B) Add 8 to both sides and you get f=12.
C) Subtract 5 from each side, and when you do that you get -k=13 which makes the answer -13.

Answers
Answer:
slope m=--3/-2=-3/2 is required slope
Answer:
m = -3, b = -2
Step-by-step explanation:
The equation is written in the form of slope-intercept, where m = slope and b = y-intercept.
The slope is the number before x. For the equation y = -3x - 2, it's -3.
The y-intercept is the constant. For the equation y = -3x - 2, it's -2.
Hence, m = -3, and b = -2.

Which values are solutions to x > 10?
A. x = 0 and x = 20
B. x = -12 and x = 0
C. X = 12 and x = 20
D. X = 11 and x = 5
Answers
Answer:
C
Step-by-step explanation:
if you plug the x values into x>10 you'll see that the only set with both numbers greater than ten is C
The solutions to x > 10 are x = 12 and x = 20 shown in option C.
What is linear inequality?Any two numbers can be compared in a linear inequality statement using symbols such as "<" ">," "≤" or "≥" These values could be algebraic, numerical, or a combination of the two.
Consider the expression x > 10
Case A: x = 0 and x = 20As x = 0 less than 10, so, this option is incorrect.
Case B: x = -12 and x = 0Since, both -12 and 0 are less than 10, incorrect option.
Case C: x = 12 and x = 20Both 12 and 20 are greater than 10. Thus, correct option.
Case D: X = 11 and x = 5As, x = 5 is less than 10, incorrect option.
Therefore, the solutions for expression x > 10 are x = 12 and x = 20.
