I think this is right
5x-2+x=9+3x+10
6x-2=19+3x
+2 +2
6x=21+3x
-3x -3x
3x=21
3x/3=21/3
X=7
If you know how to do algebra this should make sense
Answer:
1500 kg
Step-by-step explanation:
8 bags = 400 kg
1 bag = 400/8
= 50 kg
30 bags = 30×50
= 1500 kg

The required equation of the parabola is (y-5)² = 20(x+2)
<h3>Equation of a parabola</h3>
The standard equation of a parabola is expressed as;
(y-k)² = 4p(x-h)
where;
vertex = (h, k)
focus = (p+k, k)
directrix x = -p + h
Note that the directrix given will determine the type of the equation of a parabola
Given the following parameters
focus = (-2, 5) = (h, k)
x = -p + h
3 = p -2
p = 5
Substitute
(y-k)² = 4p(x-h)
(y-5)² = 4(5)(x-(-2))
(y-5)² = 20(x+2)
Hence the required equation of the parabola is (y-5)² = 20(x+2)
