Answer:
A. a way to locate data
D. a scale to plot data
Step-by-step explanation:
So Im just going to eliminate what I don't think is the answer and explain:
B. a stopping point for the data that can fit on the graph
-------An Axis can technically go on forever, so this probably isn't correct.
C. a starting point with equal intervals that follow
--------The Origin or the parent function would probably be the starting point. The axis can show equal intervals, but I wouldn't describe it as the "starting point"

Kyra is blocking off several rooms in a hotel for guests coming to her wedding. The hotel can reserve large rooms that can hold 8 people, and small rooms that can hold 6 people. Kyra reserved twice as many large rooms as small rooms, which altogether can accommodate 88 guests. Determine the number of small rooms reserved and the number of large rooms reserved.
The number of small rooms reserved is 4.
The number of large rooms reserved is 8.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
We have,
Small rooms are denoted as S.
Large rooms are denoted as L.
Now,
We will make two equations.
L = 2S _____(1)
8L + 6S = 88 ______(2)
Putting (1) in (2) we get,
8L + 6S = 88
8 x (2S) + 6S = 88
16S + 6S = 88
22S = 88
S = 88/22
S = 8/2
S = 4
Now,
Putting S = 4 in (1) we get,
L = 2 x 4
L = 8
Thus,
The number of small rooms and large rooms reserved is 4 and 8.

Simplify each algebraic expression
8(x+6)-6(x+1)+2
Answer:
2x + 44 (or) 2(x + 22)
Step-by-step explanation:
Let's solve the problem,
→ 8(x + 6) - 6(x + 1) + 2
→ 8x + 48 - 6x - 6 + 2
→ 2x + 48 - 4
→ 2x + 44
Thus, the answer is 2x + 44.
Sam's brother is two more than double Sam's age. the sum of their ages is 17. how old are the brothers
If Sam's age is S then his brother's age will be 2S + 2
Giveb that the sum of their ages is 17 then
S + 2S + 2 = 17
3S + 2 = 17
subtract two from both sides
3S = 17 - 2
3S = 15
Divide both sides by 3
S = 15/3
= 5
Sam's brother's age
= 2(5) + 2
= 12
Hence Sam is 5 and his brother is 12

Use the compound interest formula to compute the balance in the following account after the stated period of time, assuming interest is compounded annually.
$7000 invested at an APR of 3.3% for 13 years
The balance in the account after 13 years is $___
The balance in the account after 13 years is $8233.79.
Compound interest: Calculating balance in an accountFrom the question, we are to use the compound interest formula to compute the balance in the account
From the compound interest formula, we have that
A = P(1 + r/n)^nt
Where A is the amount
P is the principal
r is the interest rate
n is the number of times compounded per year
and t is the time.
From the given information,
P = $7000
r = 3.3%= 0.033
n = 1
t = 13
Putting the parameters into the formula
A = P(1 + r/n)^nt
A = 7000(1 + 0.033/1)^(1×5)
A = 7000(1 + 0.033)^5
A = $8233.79
Hence, the balance is $8233.79

Is 60o grams equal to 6 kilograms
Answer: No, they are not equal
1 kilogram = 1000 grams
6 kilograms = 6*1000 = 6000 grams
so we see that 6 kilograms is larger than 600 grams
Put another way,
600 grams = 600/1000 = 0.6 kilograms
find the range of this equation
The range of the given equation is [-1, infinity).
We are given that;
Equation y= underroot(x+5)
Now,
The domain of this equation is the set of x values that make the expression under the square root non-negative.
That is, x+5 >= 0, or x >= -5. So the domain is [-5, infinity).
The range of this equation is the set of y values that are obtained by plugging in the domain values into the equation. Since the square root function is always non-negative, and we are subtracting 1 from it, the smallest possible value of y is -1, when x = -5. As x increases, y also increases, and there is no upper bound for y.
Therefore, by the range the answer will be [-1, infinity).

The search results are unrelated to the question of finding the reflection image of (5, -3) across the y-axis. To find the reflection image of a point across the y-axis, we need to change the sign of the x-coordinate of the point. Therefore, the reflection image of (5, -3) across the y-axis is (-5, -3).

If each of X, Y, and N are positive integers, then the value of X+Y+N is 212.1
What are system of inequalities?A collection of inequalities for which we consider common solution for all inequalities is called a system of inequalities.
WE are given that A red purse contains $7, and a black purse contains $10. Each package contains X red purses and Y black purses.
X = 7
Y = 10
If there are N packages (N ≥ 2) and the total value of them is $2021
X + Y = One packages
N packages = N(X + Y ) = 10 N
if each of X, Y, and N are positive integers, then;
10 N = 2021
N = 2021/10
N = 202.1
Therefore, X+Y+N = 10 + 202.1 = 212.1

Find a Point-Slope equation for a line containing the given point and having the given slope. (4, -3); m = -1
9514 1404 393
Answer:
y +3 = -(x -4)
Step-by-step explanation:
The point-slope form of the equation for a line is ...
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
Fill in the given values.
y -(-3) = -1(x -4)
y +3 = -(x -4)
Answer:
\(y+3=-(x-4)\)
Step-by-step explanation:
Pre-SolvingWe are given that a line has a slope (m) of -1 and passes through the point (4, -3).
We want to write the equation of this line in point-slope form.
Point-slope form is given as \(y-y_1=m(x-x_1)\) where m is the slope and \((x_1,y_1)\) is a point.
SolvingSince we already know the values of the point and slope, we can plug those values into the formula.
Starting with the slope, substitute -1 as m.
\(y-y_1=-1(x-x_1)\)
When -1 is a coefficient, we can rewrite things to become:
\(y-y_1=-(x-x_1)\)
Now, substitute 4 as \(x_1\) and -3 as \(y_1\).
\(y--3=-(x-4)\)
This can be simplified to:
\(y+3=-(x-4)\)
