Y-intercept =12
Slope : y2-Y1/x2-x1
8-10/2-1
Slope : -2
y = a(x - b)^2 + c has vertex (b , c)
so here the vertex is (1, -36)
The vertical distance is 5 + 8 = 13
the horizantal distance is 3 +3 = 6
then just do pythag therom
6^2 + 13^2 = c^2
205 = c^2
<span>√205 = c

Answer:
-26= -9x + 10
-26 - 10= -9x
-36=-9x
-36:(-9)=x
4=x
Step-by-step explanation:
1. you pass +10 to the left in minus
2. you resolve what you've got on the left
then you pass the multiplying -9 to the left dividing
Answer:
x = 5.142
Step-by-step explanation:
<em>2=-74+14x</em>
if you want to make x the subject (work out its value), you need to single out x
1) the first thing that we can do is get rid of the -74
2) do this by adding it on to both sides of the equation. This is called the inverse
<em>2+-74=-72 -74+14x=14x</em>
<em>-72=14x</em>
3) to get x on its own, we now need to get rid of the 14
REMEMBER:<em> 14x = 14×x</em>
4) We do the inverse by dividing both sides by 14
<em>-72÷14=-5.142..</em>.
its surprising that its not an integer
<em>5.142=x</em>
<em>x=5.142 </em>
PLEASE LET ME KNOW IF THIS IS CORRECT
