Answer:
[tex]y= -\frac19(x-3)^2+1[/tex]
Step-by-step explanation:
the x-3 is to shift a normal parabola 3 to the right
the +1 is to lift the top up by one
the -1/9 is to compress and swapt it around
Answer:
y =- [tex]\frac{1}{9}[/tex](x - 3)² + 1
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (3, 1) , thus
y = a(x - 3)² + 1
To find a substitute another point on the graph into the equation
Substitute (1, [tex]\frac{5}{9}[/tex] ) into the equation
[tex]\frac{5}{9}[/tex] = a(1 - 3)² + 1 ( subtract 1 from both sides )
- [tex]\frac{4}{9}[/tex] = 4a ( divide both sides by 4 )
a = - [tex]\frac{1}{9}[/tex]
y = - [tex]\frac{1}{9}[/tex] (x - 3)² + 1 ← equation of parabola in vertex form

What's 29/9 as a mixed number
Answers
Answer:
3 2/9
Step-by-step explanation:
9 can go into 29 3 times with 2 leftover.
Answer: 3.2 or 3.22
Step-by-step explanation: To write an improper fraction a mixed number you start by seeing how many times the denominator (bottom number) goes in to the numerator (top number). Since the denominator is 9 and the numerator is 29, 9 goes into 29 3 times.
Maria needs to measure out liter of broth for a recipe. If she only has a container that holds liter, how many containers will she need to fill?
Answers
Answer:
20 containersStep-by-step explanation:
Let us restructure the question as:
Maria needs to measure out 10 liter of broth for a recipe. If she only has a container that holds 0.5 liter, how many containers will she need to fill?
Total litre of broth measured = 10litres
If a container holds 0.5litre, then the number of container she will need will be calculated as thus:
1 container = 0.5 liter of broth
x container = 10 liters of broth
Cross multiply
0.5 * x = 1 * 10
0.5x = 10
Divide both sides by 0.5
0.5x/0.5 = 10/0.5
x = 20
Therefore she will need to fill 20 containers.
Note that the amount of liters used in question were assumed. Same calculations can be followed for any other values given.

a bank has 120 customers. Each month the number of customers increases 20 members. Which equation represent the relationship between the number of months the bank has opened,x, and the total customers,y
Answers
explanation:
while the bank started off with 120 customers so that’s how we’re going to start it off
120 +
then later there is going to be around 20 new members each month which the x will help with that because that will be the x amount of people which you can double, triple, quadruple, that amount etc
120 + 20x
and the y will equal the whatever amount you got
120 + 20x = y
Answer:
120÷20=6 months

The original price of a $250 coat increased 7% last year. The coat is now on sale for one-half off of the new price. What is the sale price? Please help y’all
Answers
Answer:$133.75
Step-by-step explanation: So you would convert the 7% into a decimal of .07. You would multiply that by the original price of $250 and you would get $17.5 which is how much it increased. That would equal $267.5 And you would just divide that in half for your final answer of $133.75. Super easy if you know what to do. :)

Angles 2 and 4 are vertical angles, so their measures are equal.
m<2 = m<4
62 = 3y + 2
60 = 3y
y = 20
This is because since 2 and 4 are vertical angles they are equal!
62=3y+2
Next subtract 2 from each side
60=3y
And then divide 3 for your answer!

Determine if −3, −23, −43, −63, ... is an arithmetic sequence. If it is, find the common difference.
Answers
Answer:
It is an arithmetic sequence. Common difference: -20
Step-by-step explanation:
First we can find out if it is an arithmetic sequence by seeing how you get from -3 to -23. Then we see to get from -3 to -23, we need to subtract -20. It's the same with -43, so the common difference is -20. And since arithmetic sequences are the only ones common differences, then this is an arithmetic sequence. I hope this helps and I hope it's not wrong, but I do not think it is.
Colin was using the back of his book to check his homework answers. The answer that he had on his paper was −1/3 − (1/5 + 5/8). The correct answer, located in the back of the book, was −1/3 −1/5 + 5/8. Was Colin correct? Justify your response.
Answers
Answer: No. Colin was incorrect.
Step-by-step explanation:
From the question, we are informed that the answer that Colin had on his paper was −1/3 − (1/5 + 5/8) while the correct answer, located in the back of the book, was −1/3 −1/5 + 5/8.
Colin was wrong because he didn't take into effect that the minus has affected the figures in the bracket. Therefore, 1/3 − (1/5 + 5/8) simply means 1/3 - 1/5 - 5/8.
He didn't realise that (-) × (-) = + which has resulted in the change of the sign beside 5/8 from positive to negative.

Step-by-step explanation:
first multiply the numbers outside of the parenthesis.
-8x - 96 -8x = 3x -33 + 2x
second we combine like terms.
-16x - 96 = 5x - 33
third we combine the x terms over the equal line.
- 96 = -11x - 33
fourth we add 33 to - 96.
- 63 = -11x
lastly we divide by 11
= 63 divided by 11 = 5. 72 repeating

Store and he sells jeans for 7/8 of the price at Store B. Store a sells jeans for $35. Write and solve an equation to find the cost of the jeans at store B
Answers
Answer:
$40
Step-by-step explanation:
From the question, Store A sells jeans for 7/8 of the price at store B
Store A= 7/8 of the price at store B
"Of" here means multiplication in mathematics.
Store A= 7/8 × store B price
But Store A sells jeans for $35
Then $35= 7/8 × store B price
To find store B price, just cross multiply, we have
StoreB price= (8×$35)/7
StoreB price=$40
Therefore, the selling price of jeans at store B is $40

Aaron is growing two tomato plants. At the last measurement, the first plant was 6.53 inches tall and the second was 2.7 inches tall. How much taller was the larger plant?
Answers
Answer:
3.83 inches
Step-by-step explanation:
Aaron is growing two tomato plants
The first plan was 6.53 inches tall
The second plant was 2.7 inches tall
Therefore the height of the tall plant against the smaller one can be calculated as follows
= 6.53-2.7
= 3.83
Hence the larger plant is 3.83 inches taller
