Answer:
x = ±3
Step-by-step explanation:
2 = |x| - 1
Add 1 to both sides: |x| = 3
⇒ x = ±3

Answer:
y = 3x + 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 3x - 7 ← is in slope- intercept form
with slope m = 3
Parallel lines have equal slopes, thus
y = 3x + c ← is the partial equation
To find c substitute (1, 4) into the partial equation
4 = 3 + c ⇒ c = 4 - 3 = 1
y = 3x + 1 ← equation of parallel line
Circumference = 2πr
6.28 = 2πr
12 = 2n/3 +7n/3 -6
6.28 = 2×3.14×r
r =6.28/2×3.14
r= 1 unit
Now,
Area of a circle = πr² = 3.14×1×1= 3.14 sq.units
Answer:
67.5 ft^2
Step-by-step explanation:
First find the area of the circle.
A = pi r^2
A = pi (8)^2
A = 64pi
There are 360 degrees in a circle
The shaded area has 121 degrees
The fraction is 121/360
The fraction shaded is 121/360
The fraction of the circle is the same as the area
121/360 A = 121/360 * 64 pi
area shaded = 67.54488889
To the nearest tenth
area shaded = 67.5
