sum should be: 5,664 + 816 = 6,480
The answer is 24 : 12 x 1 / cos60 = 24
Answer:
D
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 =
with (x₁, y₁ ) = (- 4, 29) and (x₂, y₂ ) = (0, 28) ← 2 ordered pairs from the table
m = = -
The line crosses the y- axis at (0, 28 ) ⇒ c = 28
y = - x + 28 ← equation of line → D
Answer:
i think {x,y} = {-5,-2}
Step-by-step explanation:
X^3 + 8 = x^3 + 2^3, a sum of two cubes.
So it can be factorised using the sum of two cubes rule...
a^3 + b^3 = (a + b)(a^2 - ab + b^2).
Therefore
x^3 + 8 = (x + 2)(x^2 - 2x + 4).
Hope this helps
