Question

5x+13<28 the solution set is, just the answer I can graph it...

Answer 1

sorry... u want to know how to solve for x in \[5x+13<28\]... yeah?

Answer 2

@12thman ?

Answer 3

sorry yes

Answer 4

its for properties of inequality

Answer 5

i have to graph it

Answer 6

yep, no worries
so the inequality has 2 sides
Left side Right side
5x+13 < 28

so first, minus 13 from both sides, what are you left with?

Answer 7

15

Answer 8

5x is greater than 15

Answer 9

perfect
Left side Right side
5x < 15

now divide both sides by 5

Answer 10

x<3 ?? now how would you graph that with brackets to include 3

Answer 11

graph it by working out some points:
y = 5x+13, and
y is never greater than 28
so when x = 3,
y = 5x+13 = ?

Answer 12

next, when x = 0
y = 5x+13 = ?

Answer 13

all my choices are 4, a b and c

Answer 14

what...?

Answer 15

just gotta chose do i shade left or right

Answer 16

graph of the inequality

Answer 17

show me the answers for the above 2 questions first, then we'll draw and shade it
so when x = 3,
y = 5x+13 = ?

and when x = 0
y = 5x+13 = ?

Answer 18

28 and 13 ??

Answer 19

yep, perfect, so now we have 2 points:
(3, 28) and (0, 13)

the equation fits the equation of a straight line (y = mx + c)
so lets graph that

Answer 20

hold up its a straight line with 0 in the middle negative 10 at one side and postive 10 on the other

Answer 21

ok, now im with u, sorry

Answer 22

5x+13 <28 holds true for all values of x that are less than x = 3

so x = 2, x= 1, x= 0, x=-1 , x= -2, x= -3, x= -4 ...etc
