Answer:
-4 ± 2*sqrt(3)
Step-by-step explanation:
Well I'm not quite sure as to what the x= equations are, but for the solution to this quadratic I just used the quadratic formula. This gave me -8 ± sqrt(48)/2, which can be simplified to -4 ± 2 * sqrt(3). Hope this helps :)
Answer:
450
Step-by-step explanation:
If the perimeter is 90 inches then each side must equal 30 inches. To find the area of a triangle you mulptiply the base by the height and divide by 2. The base is 30 and the height is 30. 30*30=900. 900/2=450.
Answer:
y=(8/3)x
Step-by-step explanation:
First, we make 8x-3y=3 into the form y=mx+b
3y=8x-3
y=(8/3)x-1
For an equation to be parallel to this equation, the slope must be the same, so the new equation will be:
y=(8/3)x+b
We know that (0,0) is a point in this line. We plug (0,0) into the equation to find b:
0=(8/3)*0+b
b=0
y=(8/3)x
Answer:
Step-by-step explanation:
1/4y - 1/2
= 1/4y x 4 : 4 - 1/2
= y/4 - 1/2
