Answer:
B. Slightly more than $5
Step-by-step explanation:
y = 2x + 3
Firstly we check variables to make sure we understand.
y = dollars
x = pounds
On the scale, it says 1.126 lb. Which means 1.126 pounds.
And so, x = 1.126
y = 2x + 3
y = 2(1.126) + 3
y = 2.252 + 3
y = 2.252
The graph for part a and park b. It is underneath. I wrote 1.1, because it is rounded down from 1.126 lb, which is part b. The one with one line and no dots is part a.
Answer:
y = (x - 3)² + 6
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
Using the method of completing the square
y = x² - 6x + 15
add/subtract ( half the coefficient of the x- term )² to x² - 6x
y = x² + 2(- 3)x + 9 - 9 + 15
y = (x - 3)² - 9 + 15
y = (x - 3)² + 6 ← in vertex form
She need 1/12 cup of oil. A fraction is a portion of a whole or, more broadly, any number of equal parts. In everyday English, a fraction describes the number of parts of a specific size, such as one-half, eight-fifths, or three-quarters.
<h3>What is meant by fraction?</h3>
- A fraction is a portion of a whole or, more broadly, any number of equal parts. In everyday English, a fraction describes the number of parts of a specific size, such as one-half, eight-fifths, or three-quarters.
- fraction, A number expressed as a quotient in arithmetic, in which a numerator is divided by a denominator. Both are integers in a simple fraction.
- A complex fraction contains a fraction in either the numerator or the denominator. A proper fraction has a numerator that is less than the denominator. A fraction is a portion of a whole number and a method of dividing a number into equal parts.
<h3>How to find how much cup she want?</h3>
- She needs 1/3 cup of oil
- She have 1/4 cup of oil
To find how much need to obtain 1/3 of cup
we need to subtract what we have from what we need.
so , we have 1/4 and need 1/3
= 1/3 - 1/4
= 
= 1/12
she need 1/12 cup of oil more to make cake.

Direct variation in mathematics is when two numbers are written in an equation where one of the numbers multiplied by a constant term to equal the other.
In the table in the equation, we see direct variation.
<u>X</u> <u>Y
</u><u></u>1 7
2 14
3 21
4 28
We can find the constant of the variation by dividing y by x. This constant should remain the same for all terms of x in the table with their corresponding y values.
y/x
7/1=7
14/2=7
21/3=7
28/4=7
As we can see, the values in the table all share a direct variation between x and y with the value 7.
This can be expressed in an equation: y = 7x.
Significant Figures in Calculations:
In Order to Correct the Number of Significant Figures in a Calculation:
1.). First, you would, Add all the digits:
(Example: 1405.2 + 9.77 + 4.32 = 1419.29)
2.). Then, You would Round the final value to the Least Number of Significant Figures.
(In Example, it would look like this:
1420).
Therefore, The least number of significant figures in the Example, is 3.
(However, In the Example, the number 1420,) The "0" isn't a significant figure.
Hope that helps!!!! : )
You didn't write the significant numbers in, So, I just gave you an Example, of how would actually solve Significant Figures Calculation!
