Answer:
y = 2x + 1
Step-by-step explanation:
You can see a pattern in the group of x's that the numbers go up by 1 Also in the y-set that the numbers go up by 2. So this pattern is linear, that means the "rule" you are looking for does not have exponents or square roots or any very complicated stuff. You can use a guess and check method. Say to yourself how can I get a 7 out, when I put a 3 in? "times by2 and plus 1" works.
3 times 2, and plus1
gives you 7.
Test it on the other numbers.
-1 times2, and plus1
2(-1)+1 = -1
2(0)+1 = 1
2(1)+1 = 3
2(2)+1 = 5
It works for all the numbers.
You can calculate it also, using any two pairs of (x,y) from the data set. Put y-y on top of a fraction and x-x on the bottom. You will get the slope and that is the 2 in the "rule"
(3,7) and (2,5) for example. 7-5 so put 2 on top and 3-2 so put 1 on the bottom. 2/1 is just 2. From the point (0,1) we know the y-intercept is 1. This also gives the equation y=2x+1.
If you are just starting to learn this, probably just guess and check a rule. The rule has to work for all the points.
A spinner is divided into 5 sections of equal area, with numbers 1, 3, 5, 7, and 9 in it. What is the probability of the spinner landing on 7?
Step-by-step explanation:
You can only get 5 numbers which are : 1, 3, 5, 7, 9.
There is only one occurrence of the number 7. To get the probability of the spinner landing on 7 is given by the occurence of a certain object (7 in this case) divide by the total number of objects.
Answer:
1/5(1 over 5)
Step-by-step explanation:

Find the nth term of this number sequence
2, 4, 6, 8, ...
Answer:
As can be observed, every term in the given sequence: 2, 4, 6, 8, ..., is an even positive integer, and is, therefore, a multiple of 2:
1st term: 2 = 2(1)
2nd term: 4 = 2(2)
3rd term: 6 = 2(3)
4th term: 8 = 2(4)
Additional terms:
5th term: 10 = 2(5)
6th term: 12 = 2(6)
7th term: 14 = 2(7)
8th term: 16 = 2(8)
Therefore, using this same pattern, we see that the nth term of the given sequence is: 2n, where n is a positive integer that indicates the desired term of the sequence. For example, the 500th term of the sequence is: 2n = 2(500) = 1,000.
Notice that we add 2 to each term in order to get to the next term.
Since we use addition, we have an arithmetic sequence.
Hence, the nth term is:-
n+2

In circle H with m∠GHJ=66 and GH=10 units, find the length of arc GJ. Round to the nearest hundredth
Answer:
Step-by-step explanation:
arc length= central length/360 (circumference)
GJ=90/360 (2π20)
GJ= 31.42
31.42
The length of arc GJ is 11.5133 unit.
What is Arc length?In geometry, the arc length refers to the length of a portion of a curve or an arc of a circle. It is the distance along the curve between two endpoints of the arc.
We have,
m <GHJ = 66 and GH = 10 unit
Now, using arc length formula
= nπr / 180
= 66 x 3.14 x 10/ 180
= 11.5133 unit

Arianna paid $144 in simple interest on a $2000 loan that she repaid in 2 years. what interest rate did ariana pay on the loan
Ariana paid a 3.6% interest rate on the loan.
What is the simple interest?Simple interest is defined as interest paid on the original principal and calculated with the following formula:
S.I. = P × R × T, where P = Principal, R = Rate of Interest in % per annum, and T = Time, usually calculated as the number of years. The rate of interest is in percentage r% and is to be written as r/100.
We have been given data as:
Principal (P) = $2000
Simple interest = $144
Time (T) = 2 years
⇒ Simple interest = P × R × T
Substitute the value of P and T in the above formula,
⇒ 144 = 2000 × R × 2
⇒ 144 = 4000 × R
⇒ R = 144/4000
Apply the division operation, and we get
⇒ R = 0.036
⇒ R = 3.6 %
Therefore, Ariana paid a 3.6% interest rate on the loan.

Find the length of BC.
Explain how you got it, please!
Thanks!
Answer:
BC = 30.73
Here,
[tex]\sf \frac{AB}{BQ} = \frac{CD}{DQ}[/tex]
so first solve for QD
[tex]\sf \hookrightarrow \frac{32}{15} = \frac{19.2}{DQ}[/tex]
[tex]\sf \hookrightarrow 32(DQ)} =19.2(15)[/tex]
[tex]\sf \hookrightarrow 32(DQ)} =288[/tex]
[tex]\sf \hookrightarrow DQ =9[/tex]
Hence, QD = 9Now! using Pythagoras theorem,
CD² + BD² = BC²19.2² + (9+15)² = BC²BC = √368.64+576BC = 30.73499634BC = 30.73 ( rounded to nearest hundredth )Answer:
BC = 30.7 units (nearest tenth)
Step-by-step explanation:
As ∠AQR = ∠CQR then ∠AQB = ∠CQD
This means that ΔABQ ~ ΔCDQ
Therefore, the side lengths of two similar triangles are proportional.
[tex]\begin{aligned} \sf \dfrac{AB}{CD} & =\sf \dfrac{BQ}{QD}\\\sf \implies \dfrac{32}{19.2} & =\sf \dfrac{15.0}{QD}\\\sf \implies QD & = \sf 9 \end{aligned}[/tex]
Pythagoras' Theorem: [tex]\sf a^2+b^2=c^2[/tex]
(where a and b are the legs, and c is the hypotenuse, of a right triangle)
Given:
a = BD = BQ + QD = 15 + 9 = 24b = CD = 19.2c = BCSubstituting values into the formula:
[tex]\begin{aligned}\sf 24^2+19.2^2 & = \sf BC^2\\\sf BC^2 & = \sf 944.64\\\sf BC & = \sf \pm\sqrt{944.64}\\\sf BC & = \sf 30.7 \ (nearest \ tenth)\end{aligned}[/tex]

What is the perimeter? If necessary, round to the nearest tenth.
Answer:
10.47 to the nearest hundredth
Step-by-step explanation:
By Pythagoras
c^2 = 2^2 + 4^2 = 20
c = √20
c = 4.47
Perimeter = 2 + 4 + 4.472
The perimeter of the right-angled triangle is 6 + 2√(5) feet.
What is Pythagoras' theorem?Pythagoras' Theorem states that the square of the hypotenuse side of a right-angled triangle is equal to the sum of the squares of the other two sides.
Given that a right-angled triangle.
The perpendicular length is 2 feet, the base length is 4 feet.
We need to use the Pythagorean theorem to find the length of the hypotenuse, and then add up the lengths of all three sides to get the perimeter.
In this case, we can use it to find the length of the hypotenuse c:
2² + 4² = c²
4 + 16 = c²
20 = c²
c = √(20) = 2√(5)
Now we can add up the lengths of all three sides to get the perimeter:
Perimeter = a + b + c
Perimeter = 2 + 4 + 2√(5)
Perimeter = 6 + 2√(5) feet
Therefore, the perimeter = 6 + 2√(5) feet

m: the value of the slopeb: y-interceptLet us first find the slope:
Formula of slope = [tex]\frac{y2-y1}{x2-x1}[/tex]
(x1,y1): (5,6)(x2,y2): (8,4)Slope = [tex]\frac{4-6}{8-5} =-\frac{2}{3}[/tex]

To write it into slope-intercept form, we must solve for y
[tex]y = -\frac{2}{3}(x-5)+6 =-\frac{2}{3}x+\frac{10}{3} +6\\y = -\frac{2}{3} x+\frac{10}{3}+\frac{18}{3} \\y = -\frac{2}{3}x+\frac{28}{3}[/tex]<-- slope-intercept form

Fiona is studying how income taxes impact various families and their finances. She creates a table with various amounts of taxes owed and estimates that this represents 9% of each family’s gross income.
Using proportions, it is found that the values that complete the table, from top to bottom, are given by: $670, $920, $1500, $2100.
What is a proportion?A proportion is a fraction of a total amount.
Considering that the amounts in taxes correspond to 9% of the gross income, we have that for each family, we will find the incomes as follows:
Family 1:
0.09I = 60.30.
I = 60.30/0.09
I = $670.
Family 2:
0.09I = 82.80.
I = 82.80/0.09
I = $920.
Family 3:
0.09I = 135.00.
I = 135.00/0.09
I = $1500.
Family 4:
0.09I = 189.00.
I = 189.00/0.09
I = $2100.
