Answer:

Because there is only one out put for each domain this mapping diagram is a function.

Step-by-step explanation:

Two sets are involved. There is a directional property, the relation is defined from one set called the domain on to another set called the codomain. A function is a relation that has exactly one output for each input in the domain.

X+5=18
first get rid of the 5
so X+5-5=18-5
which makes X=13

Help: The ratio of areas of two similar figures is 8:18. The perimeter of the larger figure is 24, find the perimeter of the sma

Georgia [21]

Lets use proportion

let the perimeter of the smaller figure be 'x'

8:18::x:24

Product of means=product of extreames

24 x 8= 18 x 'x'

192=18x

x=10.6666667 units

Ans: the perimeter of the smaller figure is 10.6666667 units

Inequalities help us to compare two unequal expressions. The inequality for this scenario in standard form is 2x + 3y > 30.

<h3>What are inequalities?</h3>

Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed.

It is mostly denoted by the symbol <, >, ≤, and ≥.

Let the safety counts be represented by x, while the field goal count is represented by y.

Part A: The inequality for this scenario in standard form.

2x + 3y > 30

Part B: The inequality in slope-intercept form.

2x + 3y > 30

3y > 30 - 2x

y > 10 - (2/3)x

y < (2/3)x - 10

PartC: The inequality is represented below.
