Answer:
7
Step-by-step explanation:
-2 x 6 = -12
-6/1 ÷ -3/1 = 2
-12 - 2 = -14
-14 ÷ -2 = 7
We must know that the are of the triangle is given by definition by
A = (1/2) * (b) * (h)
where
b = base
h = height
Substituting the values
A = (1/2) * (x) * (1 + 6x)
A = (1/2) * (x + 6x ^ 2)
Since the area is 13 then
(1/2) * (x + 6x ^ 2) = 13
Clearing x we have
6x ^ 2 + x = 26
6x ^ 2 + x-26 = 0
(x-2) * (x + 13/6) = 0
As we look for the base of a triangle then x> 0
x = 2
answer
the base is x = 2
6x ^ 2 + x = 26
Rate of change = RΔ = (y2-y1)/(x2-x1) = Δy/Δx
(X1,Y1)(X2,Y2)
(1, 2) (2, 4)
RΔ = Δy/Δx
= (4-2)/(2-1)
RΔ = 2
(2, 4) (3, 8)
RΔ = (8-4)/(3-2)
RΔ = 4
(3, 8) (4, 16)
RΔ = (16-8)/(4-3)
RΔ = 8
Answer:
Step-by-step explanation:
take the current quantity and divide it by the initial quantity and multiply it by 100%
eg i had 10 cookies and ate 4. what percentage is remaining?
10 - 4 = 6 cookies remaining
6 - current
10 - initial
<u>6</u> x 100
10
= 60%
