Step-by-step explanation:
y = 2x
y = x + 1
y-1 = x
y = 2x
y = 2 (y - 1)
y = 2y - 1
y = -1
Answer:
The graph of function f of x equals log base 5
So yes , D
The only solution to this equation is 8/3, therefore the answer is C.
Answer:
(i) 22.5
(ii) 7.2
Step-by-step explanation:
(i)
AB:PQ = 2:5 = 1:2.5
So PQ is 2.5 times longer than AB.
PQ=2.5AB=(2.5)9=22.5
(ii):
Since the triangles are similar, their sides are in ratio to each other. So if PQ was 2.5 times longer than AB, QR must also be 2.5 times longer than BC:
QR=2.5BC
BC=QR/2.5=18/2.5=7.2
Answer:
Step-by-step explanation:
Let us divide by 14 by 7 which is 2, so the equation is:
Let us multiple 21 over the other side since 21 is in the denominator of the equation, so we get
So the answer is 42.
