Is -¼ + 2 ¼y + 2 - y equivalent to y + 2 ?

Mathematics
1 answer:
Juliette [100K]4 years ago
5 0

Answer: No

Step-by-step explanation:

-\frac{1}{4}+2\frac{1}{4}y+2-y=y+2

(-\frac{1}{4}+2)+(2\frac{1}{4}y-y)=y+2\\

(\frac{(-1)+(4)(2)}{4})+(\frac{9}{4}y-y)=y+2

(\frac{-1+8}{4})+(\frac{(9)(1)-(4)(1)}{4} )y=y+2

(\frac{7}{4})+(\frac{9-4}{4} )y=y+2

(\frac{7}{4})+(\frac{5}{4})y=y+2

A study analyzed the average yearly salt intake in the united states from 2012 thru 2017. the data is summarized in the table: t
Yuki888 [10]

The significance of 3,548 estimates the average grams of salt used in 2012.

A connection between independent variables and the dependent variable.is defined by the function.

Functions help to represent graphs and equations. A function is represented by two variables, one is dependent, and another one is an independent function.

The study discovered that the function can represent the data after the year 2012 as,

f(x) = 52.3x + 3,548

Where x is the number of years since 2012.

Hence, The significance of 3,548 estimates the average grams of salt used in 2012.

The hexadecimal number is 0xFEE. what will be the octal number of this?
Vikentia [17]

Answer:

0xFEE₁₆ = 7756₈

Step-by-step explanation:

Convert the hexadecimal number to decimal first

0xFEE

E = 14

F = 15

Then convert them to binary

\frac{14}{2}=7

Remainder = 0

\frac{7}{2}=3

Remainder = 1

\frac{3}{2}=1

Quotient = 1

Remainder = 1

\frac{15}{2}=7

Remainder = 1

\frac{7}{2}=3

Remainder = 1

\frac{3}{2}=1

Quotient = 1

Remainder = 1

0           F      E       E

0000  1111 1110  1110

Take groups of three

and multiply with 2^n where n is the place of the digit

111          111   101   110

4,2,1     4,2,1    4,2,1  4,2,1

4+2+1  4+2+1  4+0+1  4+2+0

7756

So, 0xFEE₁₆ = 7756₈

If A=(3,2) and B=(5,7) be two points , find the unit vector along BA
Alexeev081 [22]
If we were to plot the points on a graph, we could draw a straight lint between them. The question wants us to find the length of this line. We could make a right triangle with this line as the hypotenuse, with an x length of 2(y2-y1) and a y length of 5 (y2-y1). From there we can find the hypotenuse with Pythagorean Theorem: c^2=a^2+b^2. 
c^2=(2)^2+(5)^2
c^2=4+25
C^2=41
c=\sqrt{41}
Decimal approximation: 6.403

Hope this helps!
