Answers
Answer:The vertex is

Sometimes we have problems with the easier questions because it's not exactly in the form we're used to. Normally for a quadratic, you would complete the square to find the vertex. But this quadratic is already in vertex or standard form:

H = 15 + 3t, is the equation representing the height, in inches, of the plant tt months after Angel bought the plant.
What is an equation?Equation is a mathematical and physical statement that describes physical occurrences and the relationship between various physical quantities. It usually consists of basic variables that show physical quantities, but it may also point to a personal variable like your energy.
An equation that has a "equal to sign (=)" either reveals the answer or represents the value of the variable. However, since there is no equal sign in the case of an expression, there can be no clear answer and the value of the concerned variable cannot be displayed.
Given that,
H representing the height, in inches, of the plant
t months after Angel bought the plant
Thus, equation becomes: H = 15 + 3t

4 cakes and 3 doughnuts cost £11, 4 cakes and 7 doughnuts cost £23.
Work out the cost of one cake and one doughnut separately
Answers
A cake costs 50p
This is because from the question you can see that buying 4 more doughnuts costed £12 more
So if 4 = £12, 1 = £3
Now you have the price of a single doughnut you can work out the price of a cake.
3 doughnuts would cost 3 x £3 so £9
Then subtract this from £11 to find the price of 4 cakes.
£11 - £9 = £2
So if 4 cakes = £2, 1 cake = 50p

Then according to the above statement, we have the following equation:-
[tex]3 + 4x = 6x - 5[/tex]
Subtract 4x from both sides , we get
[tex]3 = 2x - 5[/tex]
Add 5 on both the sides , we get
[tex]8 = 2x[/tex]
Divide both sides by 2 , we get

Answer:
Area = L · A = 24 m²
L = A + 2
reemplazamos:
(A + 2) · A = 24
A² + 2A - 24 = 0 ⇒ esta es la ecuacion quadratica

Marlon earned $8.50 per hour plus an additional $80 in tips waiting tables on Saturday. He earned at least $131 in all. If h represents the number of hours Marlon worked, which inequality represents the minimum number of hours, to the nearest hour, that Marlon worked on Saturday?
Question 1 options:
8h + 80 ≥131
80h + 8.50 ≥ 131
8.50h + 80 ≤ 131
80h + 8.50≤ 131
Answers
Answer:
8.50h + 80 ≥131Step-by-step explanation:
The answer is not in the option
Step one:
given data:
we are told that the hourly earning= $8.50
then additional tip=$80
total earnings=$131.
Step two:
the linear function for the total earning is the same as the equation of a line
y=mx+c
where
y represents the total earning of $131
m represents the hourly earning= $8.50
x represents the number of hours h
c represents the tip of $80
The expression for the situation is modeled as

The sum of two number is 18. 5 times the first number subtracted from 4/7bof the second number is 14. Find the number
Answers
Answer:
The numbers are [tex]-\frac{2}{3}[/tex] and [tex]18\frac{2}{3}[/tex]
Step-by-step explanation:
Let x and y be the numbers
According to the statement, "The sum of two number is 18.", first equation will be:
[tex]x+y = 18\ \ \ \ Eqn\ 1[/tex]
And according to "The sum of two number is 18. 5 times the first number subtracted from 4/7bof the second number is 14." Second equation will be:
[tex]\frac{4}{7}y-5x = 14[/tex]
Multiplying whole equation by 7
[tex]7*\frac{4}{7}y-7*5x = 7*14\\4y-35x=98\\-35x+4y = 98\ \ \ \ Eqn\ 2[/tex]
From equation 1
[tex]x+y = 18\\y = 18-x[/tex]
Putting this in second equation
[tex]-35x+4(18-x) = 98\\-35x+72-4x= 98\\-39x = 98-72\\-39x = 26\\\frac{-39x}{-39} = \frac{26}{-39}\\x = -\frac{2}{3}[/tex]
Putting x = -2/3 in equation 1
[tex]-\frac{2}{3}+y = 18\\y = 18+\frac{2}{3}\\y = 18\frac{2}{3}[/tex]
Hence, the numbers are [tex]-\frac{2}{3}[/tex] and [tex]18\frac{2}{3}[/tex]

The sum of 324 and 135 is 503. Which number base was used for this calculation.
Answers
Answer:
Base 6 was used
Step-by-step explanation:
Here, we want to find which number base was used for the addition calculation
We start by adding the two end numbers
4 + 5 = 9
But 3 was recorded;
That means we can have 6 as the number base( 9/6 = 1 r 3)
We still continue to verify this;
The next addition is 2+3 = 5, adding the 1 brought forward, we have 6, but 0 was recorded
6/6 is (1 r 0)
This still further corroborated the earlier assertion;
then lastly 3 + 1 + 1 (1 brought forward); 5
This was recorded directly to show that the base in question is not less than 5
Hence our base of addition is base 6

Kailey correctly graphed the opposite of –3.3 on the number line.
A number line going from negative 5 to positive 5. Point A is between negative 4 and negative 3, point B is between negative 3 and negative 2, point C is at 3.3, and point D is at 3.9.
Which point could be the point Kailey graphed?
Answers
The number line shows that Kailey could have graphed the point C (3.3).
Number LineThe number line is the graphic representation of real numbers whose center is represented by the number zero (0). The negative numbers are on the left side of the number line, on the other hand, the positive numbers are written on the right side. See the attached image.
Opposite NumbersOpposite numbers are numbers that the distance to 0 is equal. The numbers are classified as the opposite when the sum between them is equal to zero (0).
STEP 1 - Plot the number linePlot the number line with the given limits: -5 to 5. See the attached image.
STEP 2 - Plot the given points in the number linePlot the points A, B,C an D in the number line drawn in step 1. See the attached image.
STEP 3 - Analyse the plotted number lineLike the point graphed is the opposite of -3.3, Kailey could have plotted the point C which is at 3.3 since the sum between -3.3 and 3.3 is equal to zero (0).
-3.3+3.3 =0
