Question

Solve the compound inequality 7x - 4 > 31 and 7x - 4 less than or greater to 59 and show all of your work. You can use <= to represent the less than or equal to symbol.
Part 2: Use complete sentences to describe the graph of the solution from Part 1.

Answer 1

Answer 2

Well, start off by trying to solve for x in both inequalities.

Answer 3

And im guessing that you mean 7x - 4 less than or equal to 59, right?

Answer 4

correct

Answer 6

You're requesting her, so I'll back off then :P

Answer 7

7x - 4 > 31
7x > 31 + 4
7x > 35
x > 5

7x - 4 < = 59
7x <= 59 + 4
7x <= 63
x <= 9

we have x is greater then 5 and less then or equal to 9
open circle on 5, closed circle on 9, shading in between

Answer 8

Quick lesson : greater then shades to the right, less then shades to the left.
Closed circle only if an equal sign is present. Open circle if no equal sign is present. Solve inequalities just like equations except in inequalities, if dividing/multiplying by a negative, the inequality sign changes.

Answer 9

THANK YOU SO MUCHH!

this is the last one I swear!

Use complete sentences to describe a real-world scenario that could be represented by the inequality 4x + 3y greater than or equal to 36.
Part 2: Choose one ordered pair that is a solution to the given inequality and explain what that ordered pair means in the context of your real-world scenario

Answer 11

mary went to the clothing store. She wanted to spend at least $36 for some clothes. She really liked the dresses and the tops. She purchased 4 dresses and 3 tops. The dresses were on sale for $8, and the tops were on sale for $2. Did she spend at least $36 ? Let x represent the dresses and y represent the tops ?

lol....I am not good at writing word problems....But this fits your equation ?

Answer 12

YESSSSSS THANK YOU!i think that's all I had to do right?

Answer 13

I do not know about this one.... because I already gave you the solution points.
They were (3,2).

Answer 14

oops...8 and 2 (8,2)

Answer 15

so is that word problem wrong?

Answer 16

@kelliegirl33 what do I do with the points?

Answer 17

hold on...I will be back...I have to go somewhere.....I promise I will be back
