Answer:
$2,700
Step-by-step explanation:
Find the total donation amount by dividing 135 by 0.05:
135/0.05
= 2700
So, the class collected $2,700 in all
One way to find out is to subsiute the points and find which ones are true
the points are (3,2) and (-2,-1)
subsiute 3 for x and 2 for y, then -2 for x and -1 for y
y-3=3/5(x-2)
2-3=3/5(3-2)
-1=3/5(1)
-3=3/5 false
-3x+5y=1
-3(3)+5(2)=1
-9+10=1
correct
try the other
-3(-2)+5(-1)=1
6+-5=1
true
one answe ris B
3/5x+1/5
this is incompleteso I can't solve it
maybe it was supposed to be 3/5x+1/5=y, but I don't know
y+1=3/5(x+1)
2+1=3/5(3+1)
3=3/5(4)
3=12/5
false
the answe ris B (maybe C but I con't know)
Answer:
x = 2
Step-by-step explanation:
H(x) = 64x - 16x²
<u>Find the value of x when the ball reaches its maximum height.</u>
<u />
Since the largest degree in this equation is two, this function represents a parabola. We can find the maximum height of the ball at the vertex of the quadratic.
In H(x) = 64x - 16x², rearrange the powers from greatest to least:
Vertex: [-b/2a, f(-b/2a)]
Substitute a and b into the x-value of the vertex: -b/2a.
The vertex of the parabola is at x = 2, with a maximum height of H(2).
