Answer:
x= -5 or x=4
Step-by-step explanation:
Lets first turn this into quadratic formula form
(-1 ±[tex]\sqrt{1^2-4*1*-20}[/tex]) / 2
(-1 ± 9 )/2
-10 / 2 =x or 8/2 =x
x= -5 or x=4

Rule 1: Multiply by 3 starting from 1. Rule 2: Add 8 starting from 4. Select the option that correctly shows the first 5 terms of each sequence.
A) First sequence: 1, 3, 9, 27, 81 and second sequence: 4, 12, 20, 28, 36
B) First sequence: 1, 3, 9, 12, 48 and second sequence: 0, 4, 12, 20, 28
C) First sequence: 1, 4, 7, 10, 13 and second sequence: 4, 12, 20, 28, 36
D) First sequence: 1, 3, 9, 12, 36 and second sequence: 0, 8, 16, 24, 32
Answer:
A
First sequence: 1, 3, 9, 27, 81
Second Sequence: 4, 12, 20, 28, 36
Step-by-step explanation:
It is not B, bc it does not multiply correctly at the #12, it is supposed to be 27 since 9 x 3 = 27. And the second sequence starts with 0 but it is supposed to start with 4.
It is not c bc it does not even multiply by 3 but adds by 3. Second sequence is technically correct but since first sequence isn't, that isn't the answer.
It is not D because it doesn't multiply correctly at #12. Second sequence is supposed to start at 4 and not 0.

IM SICK OF ALL THE FAKE LINKS! Can I get help?
Answer:
equation: 28 = 2h+ h + h or you could say 28 = 4h
h= 7
Step-by-step explanation:
since both lines are the same length they equal each other.
to get h = 7 you have to solve the equation you made.
28 = 4h
28/4 = 4h/4
7 = h

Answer:
Mean - 89
Median - 90.5
Mode - 89 or 92
Q1 - 84.5
Q3 - 96.5
IQR - 12
Step-by-step explanation:
A mean is an average. Just add all numbers then divide by how many numbers there are.
A median is a middle. Just arrange the numbers from smallest to largest and locate the middle value.
A mode is the number that appears most often. Count how many of each number there is.
Q1 is the middle of the lower half of the data.
Q3 is the middle of the upper half of the data.
IQR is the difference between Q3 and Q1. (subtract)
Beth made wristbands and belts for a craft sale. She sold 30 of these items. Each wristband sold for $5.50. Each belt sold at $8.75. If Beth made $204 at the craft sale, how many wristbands did she sell? How many belts did she sell? Write and solve a system of equations to solve the problem. Show work.
✿Answer:
Both sold 18 wristbands and 12 belts✂----------------------
Let, number of wristbands = x
number of belts = y
[tex]x+y=30[/tex] ➞ [tex]x~5.5[/tex]
[tex]5.50x+8.75y=204[/tex] [tex]x1[/tex]
[tex]5.50x+5.5y=165\\5.5x+8.75y=204\\---------\\-3.25y=-39[/tex]
[tex]y=-39/3.25[/tex]
[tex]y=12[/tex]
[tex]x=30-12=18[/tex]
[tex]So, Both~ sold ~18 ~wristbands ~and ~12~ belts[/tex].

hope it helps...have a great day!!Faith purchases a car for $27,500. The
value of the car will depreciate each
year at a rate of 12.4%. What is the
approximate equivalent monthly
depreciation rate, to the nearest tenth
of a percent?
Help please tell the explanation I’ll give brainleist
Answer:
To the nearest tenth of a percent, the approximate equivalent monthly depreciation rate is 1.0%
Step-by-step explanation:
From the question, we have a per annum decrease of 12.4%
what this mean is that, yearly, we expect a decrease of 12.4%
To get the monthly decrease value, we have to divide this given value by the number of months in a year which is 12
Thus, we have it that;
12.4%/12
= 1.0%
To the nearest tenth, the monthly decrease percentage is 1.0%

The angles in a triangle are in the ratio 1 : 2 : 3
Show that the triangle is a right-angled triangle
Answer:
see explanation
Step-by-step explanation:
sum the parts of the ratio, 1 + 2 + 3 = 6 parts
Divide 180° ( sum of angles in a triangle ) by 6
180° ÷ 6 = 30° ← value of 1 part of the ratio , then
2 parts = 2 × 30° = 60°
3 parts = 3 × 30° = 90°
The angles in the triangle are 30°, 60°, 90°
Then the triangle is right angled
Answer:
The angles are 30°, 60° and 90°.Step-by-step explanation:
Hint : sum of the angles in triangle = 180°.The triangle is a right-angled triangle.Answer:Let missing angles be [tex]x[/tex], [tex]2x[/tex].
As the triangle is right-angled triangle.
[tex]x + 2x + {90}^{o} = {180}^{o} [/tex]
[tex]3x = {180}^{o} - {90}^{o} [/tex]
[tex]3x = {90}^{o} [/tex]
[tex]x = \frac{90 ^{o} }{3} [/tex][tex]x = {30}^{o} [/tex]
[tex]2x = 30 \times 2 \\ = {60 }^{o} [/tex]
Check:30° + 60° + 90° = 180°.Hope it is helpful....What is the y-intercept of the graph?

Perpendicular to x+y=6 and passing through (0,1)
Answer:
y = x + 1
Step-by-step explanation:
x + y = 6
y = -x + 6
Perpendicular slope to -1 is 1
(0,1)
y - y1 = m(x - x1)
y - 1 = 1(x - 0)
y - 1 = x
y = x + 1
Standard form:
y = x + 1
-x + y = 1

Jayden goes out to eat with his friend, at the local diner. He orders a chicken quesadilla for $11.00. If he plans on leaving a 20% tip, for the server, how much should he leave?
Answer:
$13.20 or $2.20
Step-by-step explanation:
Since percents are decimals, we can figure out the tip by multiplying the total by the decimal percent.
11 x .20 = 2.2
Now the answer depends on what you need the answer to be. if you need the total, it's $13.20.
If you need the tip, it's $2.20.
