which expression is equivalent to | a | ≤ 4 ?
1. a ≥ –4 and a ≤ 4
2. a ≤ –4 or a ≥ 4
3. a ≤ –4 and a ≥ 4
4. a ≥ –4 or a ≤ 4

1. a ≥ –4 and a ≤ 4

Step-by-step explanation:

Rule : | a | ≤ 4 ⇔ -4 ≤ a ≤ 4

:)

parallel and congruent

step-by-step explanation:

the movement of translation is linear.   these have the same translation because you are using the same rule for each point of the triangle so you will see the same slope being used to get from a point on the triangle to its image.

same slope!   you should think parallel when you see those 2 word together (well unless it's the same line but it can't be because we are coming from different points here)

congruent! because each point is being moved the same distance.

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.
