Answer:
The answer to your question is:
a) Letter B
b) Letter D
Step-by-step explanation:
a) | x | + 3 < 10
Formula
| x | < a ⇒ - a < x < a
| x | + 3 < 10
| x | < 10 - 3
|x | < 7 solution - 7 < x < 7
or -7 < x and x < 7 Letter B
b) it must be letter D x < 4 and x < 1
You are given the equation 36 = 9x² + 4y². You are asked to find the slopes of the asymptotes of the hyperbola. A hyperbola has the following general equation x²/a² + y²/b² = 1. the goal here is to find the slopes of the hyperbolic equation. So divide both sides by 36
36 = 9x² + 4y²
(1/36)[36 = 9x² + 4y²]
1 = x²/4 + y²/9
a² = 4
a = 2
and
b² = 9
b = 3
To find the slope, divide a/b and you will get 2/3.

Mia want to buy 3 notebook for $1.29 each ,
then total cost =3×1.29
hence, 3×29
1\6+1/12+2/6=2+1+4/12
=7/12
Answer:
Whether you're teaching the meaning of fractions or fraction operations, visual models can help students connect fractions to what they already know. Division is an essential foundation for fractions. Once students can divide objects into equal groups, they can begin to grasp dividing a whole into equal parts.
