[tex]rule \: \: y = {x}^{2} + x[/tex]
Step-by-step explanation:
First thing to do is look for a pattern with the current data. What I found was the pattern, ahich is the rule. See below.
[tex]y = {x}^{2} + x[/tex]
Now insert the given values for x and y into the rule.
[tex]y = - {3}^{2} - 3 \\ y = 6 \\ \\ 30 = {x}^{2} + x \\ x = 5 \\ \\ y = {1}^{2} + 1 \\ y = 2[/tex]
WILL GIVE BRAINLIEST!!!! ANSWER ASAP!!!
Solve for x: 2|2x − 2| + 4 = 20. (5 points)
x = 5, x = −3
x = 5, x = −5
x = 3, x = −3
x = −5, x = 3

An isotope of iodine has a mass of 134 amu. How many neutrons does the
isotope contain?
A. 67
B.153
C. 81
D. 74
Answer:
The correct option is C: the isotope of iodine contains 81 neutrons.
Step-by-step explanation:
The mass (A) of the iodine isotope is given by:
[tex]A = Z + N[/tex]
Where:
Z: is the number of protons
N: is the number of neutrons
For iodine Z= 53, so if A = 134 the number of neutrons is:
[tex] N = A - Z = 134 - 53 = 81 [/tex]
Therefore, the correct option is C. The isotope of iodine contains 81 neutrons.

C None of the other answers are correc
D = -8-5(1-1) a = 5+8(n-1)
Answer: B
Step-by-step explanation:
The equation for an arithmetic sequence is:
aₙ = a₁ + d(n - 1)
This matches answer B, so lets test it.
Substitue the position values for n
Given: Position 1 = -8
Solve Position 2:
a₂ = -8 + 5(2 - 1) = -3
a₃ = -8 + 5(3 - 1) = 2
a₄ = -8 + 5(4 - 1) = 7
a₅ = -8 + 5(5 - 1) = 12

Between them Molly and Sue have 32 marbles. Molly has 3 times as many as Sue. How many marbles does each girl have?
Answer:
Sue has 8 marbles
Molly has 8 marbles
Step-by-step explanation:
m = number of marbles Molly has
s = number of marbles that sue has
m+s =32
m = 3s
Substitute the second equation into the first equation
3s+s =32
4s = 32
Divide by 4
4s/4 =32/4
s = 8
Sue has 8 marbles
m = 32 = 3*8 = 24
Molly has 8 marbles
The approximate areas of two states are listed below. Texas: 2.69\times10^5 square miles Rhode Island: 1.21\times10^3 square miles Determine the difference, in square miles, between the area of Texas and the area of Rhode Island. Write your answer in scientific notation.
Answer:
10 times 5 =50 (2.69 x 50) = 134.5
10 times 3=30 (1.21x30)= 36.3
Step-by-step explanation:
The difference between the area of Texas and Rhode Island in square miles and scientific notation should be (2.68 × 10⁵) square miles.
Calculation of the area:Area of Texas = (2.69 × 10⁵) square miles = 269000 square miles
Area of Rhode Island = (1.21 × 10³) square miles = 1210 square miles
Now
Difference between the Area of the Texas and Rhode Island should be
= 269000 - 1210
= 267,790 square miles
= (2.68 × 10⁵) square miles.

Simplify: (–6, –3) Mary Beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. Examine the steps to determine whether she made an error. The student made .
Answer:
The answer is below
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation is rotation, reflection, translation and dilation.
If a point (x, y) is rotated 90° counterclockwise, its new coordinate is (–y, x).
Give point M (3, –6) is rotated 90° counterclockwise:
Step 1: Interchange the x- and y-coordinates to get (-6, 3)
Step 2: Multiply the new x-coordinate by –1 to get (-6(–1), 3)
Step 3: Simplify to get (6, 3)
Therefore she made an error in step 1

it is easier to see the relation between the various parts, and how it
might be simplified, when you see it in the latter form. Notice that I
didn't have to use parentheses at all; that's because the bar serves
the double purpose of indicating division and of separating the
divisor from the dividend. In fact, this usage derives in part from an
old use of the bar (called a vinculum) to do what we usually do with
parentheses today, by putting a bar above any group of symbols that
are to be kept together:

Gayle made a
baby quilt using 24 equal squares. What
are the dimensions of 1 square? Describe
two different ways to find the answer.
Answer:
[tex]Measurement = 0.75ft[/tex]
Step-by-step explanation:
See attachment for complete question
Method 1:
Considering the width and length of the quilt
Given
[tex]Number\ of\ squares = 24[/tex]
Required
Determine the dimension of 1 square
The width of the quilt is 4.5ft and there are 6 squares in that dimension.
Each measurement is calculated as thus:
[tex]Measurement = \frac{4.5ft}{6}[/tex]
[tex]Measurement = 0.75ft[/tex]
Or
The length of the quilt is 3ft and there are 4 squares in that dimension.
Each measurement is calculated as thus:
[tex]Measurement = \frac{3ft}{4}[/tex]
[tex]Measurement = 0.75ft[/tex]
Method 2:
Calculate the area of the quilt.
[tex]Area = 4.5ft * 3ft[/tex]
[tex]Area = 13.5ft^2[/tex]
The area of 1 of the 24 squares is calculated by dividing the total area by number of squares
[tex]Area = \frac{13.5ft^2}{24}[/tex]
[tex]Area = 0.5625\ ft^2[/tex]
Represent the dimension of individual square with L
Area of a square is:
[tex]Area = L * L[/tex]
This gives:
[tex]L * L = 0.5625[/tex]
[tex]L^2 = 0.5625[/tex]
Take square root of both sides
[tex]L = \sqrt{0.5625[/tex]
[tex]L = 0.75ft[/tex]
Hence, the dimension of each square is 0.75ft

What is the rise between the points (0,0) and (8, 12)?
Answer:
8/12 or x+8 y+12
Step-by-step explanation:
The rise between the points (0,0) and (8,12) is 12.
What is the slope?The ratio of the vertical and horizontal changes between two points on a surface or a line is known as the slope.
Rise is the difference of y-coordinates of the points.
Therefore, the rise between the points (0,0) and (8,12) is:
12 - 0
=12
Hence, the rise between the points (0,0) and (8,12) is 12.
