PLEASE HELP , WILL GIVE A BRAINLY. What is the domain of the function?
Answer: I believe it is a. Sorry if I am incorrect
Step-by-step explanation:
Functions assign outputs to inputs. The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0.

What is the slope of the line on the graph?
Enter your answer in the box.
Answer: The slope of the line is 6.
You can use the distance formula to find the slope (Y2-Y1/X2-X1). You can plug in any two points seen on the graph into the formula. I will use (0,-1) and (1,5). When I plug in the values, 5-(-1)/1-0=6/1=6. So the slope of the line is 6.

1: 12 * [tex]10^{9}[/tex]
We can easily tell this is the answer here as 12 is larger than 4. They are both being multiplied by the same power of 10, so we can ignore that part and still tell which is larger.
2: 3 * [tex]10^{12}[/tex]
Same here, we can easily tell this is the answer here as 3 is larger than 1.5. They are both being multiplied by the same power of 10, so we can ignore that part and still tell which is larger.
3: 6 * [tex]10^{5}[/tex]
This one is slightly more complicated than the other two, but still not to difficult when you know what you're doing.
A tip: 10 to the fourth power ([tex]10^{4}[/tex]) is 10,000. Aka, a 1 with four zeros!
For the first one, 20 has a zero, so we can take it and put it onto the 10th power. We know have:
2 * [tex]10^{5}[/tex] and 6 * [tex]10^{5}[/tex]
Using the same method as #1 and #2, we can tell that 6 * [tex]10^{5}[/tex] is the answer here!

Suppose Felipe has 9.24 pounds of seed if it takes 6.6 pounds of seed to plant on acre of grass how many acres of grass can be planted?
Answer:
1.4 acres of grass can be planted.
Step-by-step explanation:
He has 9.24 pounds of seeds.
If one acre of grass needs 6.6 pounds of seeds we can divide 9.24 pounds by 6.6 pounds to find how many acres of grass he can plant.
9.24 lbs × [tex]\frac{1acre}{6.6 lbs}[/tex] = 1.4 acres

<B ~ <C isosceles Triangle Theorem
The length of the side AB and AC will be congruent with each other. Then the triangle ΔABC will be an isosceles triangle.
What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.
The two triangular legs and their opposing angles are congruent in an isosceles triangle.
In triangle ΔABC, then the length of the side AB and AC will be congruent to each other.
AB = AC
Then the triangle ΔABC will be an isosceles triangle.

The value of xis
and the value of yis
Answer:
x = -8/3
y = 5
Step-by-step explanation:
Finding the equation of the line:
y = 3x +c
Substituting (-2,5) into 'y=3x+c':
5 = -6 + c
c = 11
Hence,
y = 3x + 11
For finding x:
Substituting (x, 3) into 'y = 3x +11':
3 = 3x + 11
3x = -8
x = -8/3
For finding y:
Substituting (-2, y) into 'y = 3x + 11':
y = -6 + 11
y = 5

guys help please what is this
Answer:
A & C
Step-by-step explanation:
You're looking for rational numbers that are also integers, but because (as the figure shows) ALL integers are already rational, you only have to worry about the integer part. An integer is a whole number, positive or negative. So, you need to simplify each element of each set (the numbers inside the curly braces) to see if they're whole.
A - The square root of 100 is just 10 or -10, divided by -2 is -5 or 5. 4, -2, 5, and -5 are all integers.
B - Wrong because 4/3 is not a whole number
C - 16/4 is just 4, and the square root of 49 is 7 or -7. 4, -6, 2, 7, & -7 are all integers.
D - Wrong because 27/2 is not a whole number
E - Wrong because 0.2 is not a whole number

I need help with this math
Answer:
D
Step-by-step explanation:
∠1 + ∠2 = 180 {Supplementary angles}
6x + 15 + 3x + 3 = 180
6x + 3x + 15 + 3 = 180
Combine like terms
9x + 18 = 180
Subtract 18 from both sides
9x = 180 - 18
9x = 162
x = 162/9
x = 18
∠2 = 3x +3
= 3*18 + 3
= 54 + 3
∠2 = 57°

The total cost after sales tax to fix Azar’s computer is represented by the expression 0.08 (55h) + 55h, where h represents the number of hours it takes to fix Azar’s computer.
What percentage sales tax is Azar being charged? Explain your answer using 1-2 sentences
What part of the expression represents the dollar amount of sales tax Azar must pay?
Answer:
these are 5 points look clearly.XD
The percentage sales tax is 8%.
The part of the expression that represents the dollar amount of sales tax Azar must pay is 0.08 55(h).
Given,
The total cost after sales tax to fix Azar’s computer is represented by the expression:
- 0.08 (55h) + 55h
where h represents the number of hours it takes to fix Azar’s computer.
We need to find out what percentage of sales tax is Azar being charged.
and what part of the expression represents the dollar amount of sales tax Azar must pay.
What represents sales taxes?It is mostly represented by a percentage.
We have,
100% = 100/100 = 1
50% = 50/100 = 1/2 = 0.5
25% = 25/100 = 1/4 = 0.25
20% = 20/100 = 1/5 = 0.2
We have,
- 0.08 (55h) + 55h
The sales tax is also charged according to the number of hours so,
In the expression 0.08 can be written as a percentage.
0.08 = 8 /100 = 8%
The percentage sales tax is 8%.
Now,
0.08 55(h) means the sales tax Azar must pay.
For 1 hour,
0.08 x 55 = 4.4 is the sales tax.
For 2 hours,
0.08 x (55x2) = 0.08 x 110 = 8.8.
And so on,
So,
The part of the expression that represents the dollar amount of sales tax Azar must pay is 0.08 55(h).
Thus,
The percentage sales tax is 8%.
The part of the expression that represents the dollar amount of sales tax Azar must pay is 0.08 55(h).
