Answer:
X = 215/9
Step-by-step explanation:
- 3/5 * 5(3x + 6) = 197
-3 *(3x + 6) = 197
-9x - 18 = 197
- 9x = 197 + 18
X = - 215/9

Step-by-step explanation:
area of circle = πr² = 25π ft²
area of sector = 25π × 221°/360° ≅ 48.21 ft²
Answer:
y = 9x - 11
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 )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 3, - 38) and (x₂, y₂ ) = (8, 61)
m =
=
= 9, thus
y = 9x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (8, 61), then
61 = 72 + c ⇒ c = 61 - 72 = - 11
y = 9x - 11 ← equation of trend line
Answer:
x = 2
Step-by-step explanation:
4 x + (negative 4) = negative 2 x + 8
4x + (-4) = - 2x + 8
4x - 4 = - 2x + 8
4x + 2x = 8 + 4
6x = 12
