thanksssss for the points
The first step for absolute value equations is to isolate the expression contained within the absolute value bars:
3|2x+4|-1 = 11
3|2x+4| = 12
|2x+4| = 4
so |2x+4| is 4 units away from 0 on a number line, but we don't know in which direction -- negative or positive? you'll have two answers.
2x+4 = 4
AND
2x+4 = -4
solve both of those two step equations and you'll get
x = 0
AND
x = -4
so 0 and -4 are your solutions.
Rotation
It’s rotating 90 degrees counterclockwise
3/7 or 3:7 because you tossed the dice 7 times and got an even number 3 of those times.
Answer:
see below
Step-by-step explanation:
given:
radius of a circle = 3cm
find:
1. diameter
2. radius
3. r²
1) diameter = twice the radius = 2 r = 2 (3) = 6 cm
2) radius = 3 cm
3) r² = 3² = 9 cm
