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.

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.
