Which equation matches the graph of the greatest integer function given<br> below?

saveliy_v [14]

Answer:

$y = x + 2$

Step-by-step explanation:

Given

The attached graph

Required

Determine the equation

First, pick any 2 corresponding coordinates

$(x_1,y_1) = (0,2)$

$(x_2,y_2) = (6,8)$

Next, calculate the slope (m)

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{8-2}{6-0}$

$m = \frac{6}{6}$

$m =1$

The equation is calculated as:

$y - y_1 = m(x - x_1)$

Where:

$(x_1,y_1) = (0,2)$ and $m =1$

$y - 2 = 1(x - 0)$

$y - 2 = (x - 0)$

$y - 2 = x$

Make y the subject

$y = x + 2$

What is the GCF of 21x^3+14x^2+35x

Archy [21]

I like prime factorization for finding the GCF:
$21x^3=3^.7^.x^.x^.x$
$14x^2=2^.7^.x^.x$
$35x=5^.7^.x$

What common things can you pull from each term...It must be the same amount from each?
7x

Alvin is 12 years younger than Elga. The sum of their ages is 86 what is Algas age

Ede4ka [16]

9514 1404 393

Answer:

Alvin: 37
Elga: 49

Step-by-step explanation:

Let 'a' and 'e' represent Alvin's and Elga's ages, respectively.

a = e-12 . . . . . Alvin is 12 years younger

a + e = 86 . . . the sum of their ages is 86

Substituting for 'a' gives ...

(e -12) +e = 86

2e = 98

e = 49

a = 49 -12 = 37

Alvin is 37; Elga is 49.
