Which linear inequality is represented by the graph?

Tema [17]

Answer:

$y\leq \frac{2}{3}x+\frac{1}{5}$

Step-by-step explanation:

step 1

Find the equation of the solid line

Find the slope

we have

(0,0.2) and (3,2.2)

$m=(2.2-0.2)/(3-0)=\frac{2}{3}$

The y intercept b is equal to

$b=0.2=\frac{2}{10}=\frac{1}{5}$

the equation of the solid line in slope intercept form is equal to

$y=\frac{2}{3}x+\frac{1}{5}$

step 2

Find the equation of the inequality

we know that

The solution of the inequality is the shaded area below the solid line

therefore

$y\leq \frac{2}{3}x+\frac{1}{5}$

Find a three digit number. The tens digit is 3 time the hundreds digit. The sum of the digits is 15. If you reverse the digits,

tresset_1 [31]

Answer:

number = 267

Step-by-step explanation:

i am a 3 digit number divisible by 3.

100a + 10b + c

my tens digit is 3 times as great as my hundreds digit

b = 3a, from this we know a = 1, 2, 3, then b = 3, 6, 9

and the sum of my digits is 15.

a + b + c = 15

if you reverse my digits i am divisible by 6 and 3

100c + 10b + a

this is a logic problem, an equation won't help us here

From the given information b = 3a, and the sum of the 3 digits = 15, we have:

1 3 ___; three single digits can't add up to 15

2 6 _7_; this has to be the number

3 9 _3_; reverse number is not different

Check for division by 3 and 6

267/3 = 89

762/6 = 127

267 is the number
