Answer:
20/24
Step-by-step explanation:
let the variable be x and x-4
5/6 = x-4/x
cross multiply
5x = 6x - 24
24= x
thus, x is 24 and x-4 is 20
<u>20/24</u>
So five times five is twenty five. Then do three times fifteen which is forty five.
25+45=70
Answer: Thus when transforming from ABC to A'B'C', the lengths are scaled by a factor of 0.5 .
Step-by-step explanation:
Since the triangles are similar, the ratio of their sides are equal.
And we can count the number of blocks over which AC and A'C' is drawn and take them to be their length,
Therefore,
AC = 16
A'C'= 8
Thus when transforming from ABC to A'B'C', the lengths are scaled by a factor of 0.5 .
Measuring the tans of the angles by taking the ratio of opposite by adjacent, we get,
tanA = 
tanA'=
which means tanA= tanA'
The angles do not change.
Thus when transforming from ABC to A'B'C', the lengths are scaled by a factor of 0.5 .
Answer:
7) Decay
8) Growth
9) Growth
10) Growth
Step-by-step explanation:
7) As <em>x </em>increases, <em>y </em>is decreasing because as you add more value to the exponent, 1/3 gets smaller and smaller.
8) As <em>x </em>increases, <em>y </em>is increasing because as you add more value to the exponent, 2 gets bigger and bigger.
9) As <em>x </em>increases, <em>y </em>is increasing because as you add more value to the exponent, 2 gets bigger and bigger.
10) As <em>x </em>increases, <em>y </em>is increasing because as you add more value to the exponent, 2 gets bigger and bigger.
