Answer: 4=y
Step-by-step explanation:
6(7 -3y)+6(y+1)
42-18y+6y+6
48-12y
48/12=4
12y/12=y
4=y
<span>area of a circle = pi * r^2
radius (r) = half the diameter = 3.5 units
area = 3.14 * 3.5^2 = 38.47 units so thats wat it means</span>
Answer:
0.15x=x-30
Step-by-step explanation:
Let
x-----> the regular price
we know that
15%=15/100=0.15
so
0.15x=30
x=30/0.15=$200
<em>Verify each case</em>
case a) 0.15x=30
x=30/0.15=$200
therefore
The equation could be used to determine x
case b) 0.85x=x-30
x-0.85x=30
0.15x=30
x=30/0.15=$200
therefore
The equation could be used to determine x
case c) 0.15x=x-30
x-0.15x=30
0.85x=30
x=30/0.85=$35.29
therefore
The equation could not be used to determine x
case d) x-0.15x=x-30
-0.15x=-30
0.15x=30
x=30/0.15=$200
therefore
The equation could be used to determine x
Answer:
3 + 5i
Step-by-step explanation:
-2i + (9 - 3i) - (6 - 10i) = -2i + 9 - 3i -6 + 10i
= -2i - 3i +10i + 9 - 6 = 3 + 5i
B=y=-x/2-1 <span>(-6,2). When x of the line is -6, y of the line must be 2.</span>Because you said the line passes through this point, right?
Now, look at our line's equation so far: . b is what we want, the -1/2 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the the point (-6,2).
So, why not plug in for x the number -6 and for y the number 2? This will allow us to solve for b for the particular line that passes through the point you gave!.
<span>(-6,2). y=mx+b or 2=-1/2 × -6+b, or solving for b: b=2-(-1/2)(-6). b=-1.</span>
