Answer:
d
Step-by-step explanation:
A segment joining the midpoints of a triangle is
• Parallel to the third side
• Half the length of the third side
The segment DF joins the midpoints of 2 sides of Δ ABC , then
BC = 2 × DF = 2 × 4 = 8
Answer:
3, -3, -1/2
Step-by-step explanation:
There is no need to distribute, just set each parenthesis to equal to zero.
p(x)= (x-3)(x+3)(2x+1)
X-3=0 x+3=0 2X+1=0
+3 +3 -3 -3 -1 -1
X=3 X=-3 2x=-1
x=-1/2
So your answers are 3, -3, -1/2
Add the probabilities
3/8+1/3=9/24+8/24=17/24
Slope-intercept form can be written as
y = mx + b
From the question above, we should move x to another side (right side), so the left side only contains of y-variable
-3x + 2y = 12
2y = 12 + 3x
To make slope-intercept form, only y is on the left side. We should move the coefficient 2 to the right side.
2y = 12 + 3x
2y = 3x + 12
y = (3x + 12)/2
Simplify the equation
y = (3x + 12)/2
y = (3/2)x + 12/2
y = (3/2)x + 6
This is the final answer ⇒ y = (3/2)x + 6
I think 4 divided by 8/9 - 1/2 = 4
