Hey there!!
Given equation :
-0.4 ( 3x - 2 )
Using the distributive property:
-1.2x + 0.8
And given : x = 4
-1.2(4) + 0.8
-4.8 + 0.8
4
Hence, the required answer is 4.
Hope it helps!!
Answer:
Step-by-step explanation:
The midpoint formula is:
where (x₁, y₁) and (x₂, y₂) are the points are the endpoints.
We are given the points: (2,4) and (6,8). Therefore,
Substitute the values into the formula.
Find the x coordinate first.
- Add 2 and 6: 2+6=8
- Divide by 2: 8/2=4
Find the y-coordinate next.
- Add 4 and 8: 4+8= 12
- Divide by 2: 12/2=6
The midpoint of EF is (4,6)
<span>Let's use the quadratic formula:
2w² -</span><span><span> 20w </span>+ 50 = 0</span>
a = 2 b = -20 c = 50
x = -b +-sq root(b^2 - 4*a*c) / 2*a
x = --20 +-sq root(400 -4*2*50) / 4
x = 20 +-sq root(400 -4*2*50) / 4
x = 20 +-sq root( 0) / 4
x = 20 / 4 =5
I'd say it has one rational solution.
It does NOT have 2 solutions because the "plus / minus" section = 0.
