Is -57.5 a interger

1 answer:

8 0

Integers are positive or negative whole numbers, so no fractions or decimals.

-62, and 32/4 are integers.

32/4 is an integer because it simplifies to 8.
-57.5 is not an integer because it has a decimal.

Hope this helps!

Answer:

Step-by-step explanation:

looking at the graph,

when x = 3, y = -10

-10 = 2(3)^2 + 3b + 8

-10 = 18 + 3b + 8

-10 = 26 + 3b

3b = -36

b = -36/3

b = -12

Can someone help me?

Rasek [7]

Step-by-step explanation:

$given \: - 5n = 4m$

making m the subject first by dividing through by 4

$\frac{ - 5}{n} = \frac{4m}{4}$

$m = \frac{ - 5n}{4}$

from the question, given n = -1 ,0 ,1

so when n= -1

$m = \frac{ - 5( - 1)}{4}$

$m = \frac{5}{4}$

when n=0

$m = \frac{ - 5(0)}{4}$

$m = \frac{0}{4}$

$m = 0$

when n=1

$m = \frac{ - 5(1)}{4}$

$m = \frac{ - 5}{4}$

Rewrite the equations;
m+4n=8
m-n=-2

Eliminating m gives;
5n=10
n=2
Replacing for n in the first equation;
m+4(2)=8
m=8
Answer;
(0, 2)
