Mathematics

Answer:

False

Step-by-step explanation:

When there is an open circle, it means that it can't be that exact number. If there is a closed circle, it can be that number. This is an open circle, and means that it is less than 2.

Answer:

False

Step-by-step explanation:

The open circle means you should not include the number it is on.

The inequality would look like, x<2 and not equal to. Therefore, 2 is not a solution.

Write an equation for the line shown pictured in the graph.
guajiro [1.7K]

Answer:

<u>4y =  x + 13</u>

Step-by-step explanation:

The general equation of the line y = mx + c

where m is the slope and c is constant represent y-intercept

The line shown in the graph pass through the points (3,4) , (-1,3)

The slope of the line = (y₂-y₁)/(x₂-x₁) = (3-4)/(-1-3) = -1/-4 = 1/4

∴ y = (1/4) x + c

Substitute with the point (3,4) to find c

∴ 4 = (1/4) 3 + c

∴ c = 4 - 3/4 = 13/4

∴ y = (1/4) x + 13/4 ⇒ multiply both sides by 4

∴ 4y =  x + 13

So, The equation of the line in the graph: 4y =  x + 13

The equation can be written as <u>y = (1/4) x + 13/4  OR  4y - x = 13</u>

Simplify the ratio 3:2.1
Andre45 [30]
<h3>Answer is   10:7</h3>

=======================================================

Explanation

It sounds like you want the decimal number to become a whole number. If so, then one way is to multiply both parts by 10 to move that decimal point over one spot to the right

3*10 = 30

2.1*10 = 21

The ratio 3:2.1 is equivalent to 30:21

-----

Then notice how 30 and 21 have the greatest common factor 3. Divide both parts by 3 so we can fully reduce this ratio

30/3 = 10

21/3 = 7

The ratio 30:21 simplifies fully to 10:7

The numbers 10 and 7 do not have any factors in common, other than 1, so we cannot reduce 10:7 any further.

There are 17 animals in the barn. Some are ducks and some are sheep. There are 48 legs in all. How many of each animal arr there
mafiozo [28]

Answer:

x=10 , y=7

Step-by-step explanation:

x + y = 17

we know that ducks has 2 feet and sheep has 4 feet.

so, 2x + 4y = 48

x = 17 -y

2(17-y) + 4y = 48

34 - 2y + 4y = 48

2y = 48 -3 4

2y =1 4

y=7

x + 7 = 17

x = 17-7

x=10
