Answer:
110 and 70
Step-by-step explanation:
opposite sides of parallelograms are equal so you can set 2x+30 equal to 5x-90
when you do this:
2x+30=5x-90
-2x -2x
30=3x-90
+90 +90
120=3x
/3 /3
40=x
now you can plug 40 in for 5x-90
example:
5(40)-90
200-90
110
m<r=110
<r and <s are supplementary because they are consecutive angles
supplementary is when two angles add up to 180
since <r is 110, do 180-110 and get 70
m<s = 70
The standard equation is 4p(x-h) = (y-k)^2 where |p| = focal distance |4p| = focal width.
<span>x=-1/8y^2
-8x=y^2
4*(-2)(x-0) =( y-0)^2
p = -2, h=0, k=0</span><span>
focal width = |4*(-2)| = 8
The answer to your question is that the length of the focal width is equal to 8.</span>
Answer:
.......C........
Step-by-step explanation:
......
The linear rule should look like this y=a*x+b
As the function graph goes through the (0,0) point, the equation 0=a*0+b <=> b=0 must be true.
Now we only need to find a, using one of the points given. With (-4, 16):
16=-4*a <=> a=16/-4 <=> a= -4
So the rule looks the following way:
f(x)= -4*x
