the point (-1,11)
Answers

Answer:
y = (x -3)² -5y = x² -6x +4Step-by-step explanation:
The vertex form of the quadratic equation is ...
y = a(x -h)² +k . . . . . . . . . vertex (h, k); vertical scale factor 'a'
Given the vertex, we can find the scale factor by substituting the given point values:
11 = a(-1 -3)² -5
11 = 16a -5
a = (11 +5)/16 = 1
So, the vertex form equation is ...
y = (x -3)² -5 . . . . . vertex form
Expanding this gives the standard form.
y = x² -6x +9 -5
y = x² -6x +4 . . . . . standard form

6x-6y=23 find y when x=8
Answers
Answer:
y= 4.166
If rounded to the nearest tenth
y = 4.2
Step-by-step explanation:
6x - 6y = 23
x = 8
6x - 6y = 23 (Sub in the x with 8)
6(8) - 6y = 23
48 - 6y = 23 (Subtract each side by 48)
-6y = 23 - 48
-6y = -25 (Divide each side by -6)
y = 4.166
If rounded to the nearest tenth
y = 4.2

The original price of the Kindle is $269.99.
If the Kindle was 15% off, what is the discounted price of the Kindle?
Answers
Answer:
229.4915
Step-by-step explanation:
you first find 15% of $269.99 which is 15/100 * 269.99
which is 40.4915
and since you are finding the discounted price
you subtract 40.4915 from 269.99
= 269.99-40.4915
=229.4915
dont forget to put the unit ($)
=$229.4915

Juan wants to buy some protein bars and magazines for a trip.
He has decided to buy three times as many protein bars as
magazines. Each protein bar costs $0.70 and each magazine
costs $2.50. The sales tax rate on both types of items is 734%.
How many of each item can he buy if he has $20.00 to spend?
What Is the answer I don’t know
Answers
Answer:
HI there! I am really sorry if i get this wrong, but please apperciate!
Thank you! :)
Step-by-step explanation:
So I worked this out like this:
Protein bars: 0.70 * 3 = 2.1
Magezines: 2.50
734% are the taxes as it was written. 734% decimal version is 7.34.
This is what I did next:
7.34 plus 2.1 times 2 equals 18.88. So, you can buy 2 protein bars.
7.34 plus 2.50 times 2 equals 19.68. So, you can also buy 2 magazines!
I hope this helps! Let me know if this is wrong. Thanks and have a nice day!

A triangle is 20 in tall and 5 in wide. If it is reduced to a width of 1 in then how tall will it be?
Answers
Answer:
4 inches tall
Step-by-step explanation:
To find how tall it will be, use the same reduction scale that was used to reduce the width.
This scale is 5, since 5 divided by 5 is 1.
So, to find how tall it will be, divide 20 by 5:
20/5
= 4
So, it will be 4 inches tall

Mumuni Bawumia, a farmer sells 500 litres of fresh milk a day with a standard deviation of 35 litres. Given that the daily sales of fresh milk is normally distributed, what is the probability that the sales in any single day is:
a. Greater than 506 litres
b. Between 498 litres and 506 litres.
Answers
Answer:
a: 0.43194
b: 0.09084
Step-by-step explanation:
First construct the z values for 498 and 506.
[tex]z=\frac{x-u}{s}[/tex]
[tex]z(498)=\frac{498-500}{35}[/tex]=-0.05714
z(506)=(506-500)/35=0.17143
Check the cumulative normal distribution tables to find
P(x<=-0.05714)=0.47722
P(x<=506)=0.52278
These probabilities imply that
P(x>506)=1-P(x<=506)=1-0.52278=0.43194
P(498<=x<=506)=P(x<=506)-P(x<=498)=0.09084

What is an expression?
An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
The sum of seven-eighths of a number and 20 is 34 at minimum.
This means,
(7/8)M + 20 = 34
7M/8 = 34 - 20
7M/8 = 14
7M = 14 x 8
M = 2 x 8
M = 16
This means,
The number will be 16 or greater than 16.
Thus,
The number will be 16 or greater than 16.

An angle measures 12°. Find its complement. Do not include units in your answer.
Answers
Answer:
78
Step-by-step explanation:
complements = 90
x + 12 = 90
-12. -12
× = 78
If two angles are complementary,
then the sum of their measures is 90 degrees.
If two numbers add to 90, we can represent those numbers as x and 90 - x.
So we will call one of our angles x and its complement as 90 - x.
So we have 90 - 12 which is 78.
So the complement of a 12° angle is a 78° angle.
