Find the solution set to each inequality. express the solution in set notation and graphically on the number line.
a. 6x - 5 < 7x + 4
b. x² + 3(x - 1) ≥ x² + 5

a) (-9, +∞)

b) [8/3, +∞)

Step-by-step explanation:

a) 6x - 5 < 7x + 4

We need to write the terms with x on one side and the terms without x on the other side

6x - 5 < 7x + 4

-5 - 4 < 7x - 6x

-9 < x

Therefore x >-9, in set notation this would be (-9, +∞)

b)  x² + 3(x - 1) ≥ x² + 5

We need to solve first the parentheses and combine like terms

x² + 3(x - 1) ≥ x² + 5

x² +3x -3 ≥ x² + 5

x² - x² + 3x ≥ 5 + 3

3x ≥ 8

x ≥ 8/3

Therefore, the solution in set notation would be [8/3, +∞)

what?

step-by-step explanation:

what do you need with. i love quadrants. can you tell me ?

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
