Express the set -4x+21 ≤ 3x +14 using interval notation please give an explanation this is part of my review and i am having a hard time understanding what i’m doing wrong maybe i’m flipping the sign incorrectly or something in turn messing up my notation. thank you so much!

[1, ∞)

Step-by-step explanation:

1) Solve for x

-4x + 21 3x + 14

21 7x + 14

7 7x

1 x

2) 1 is the lowest possible value of x and since it's a smaller or equal to inequality, you use a square bracket. If it was 1 < x, it would be a round bracket. Since there isn't a boundary for the highest value of x, you write an infinity. When you have an infinity, it's always a round bracket.

b. the decimal could be two-tenths.

step-by-step explanation:

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )
