Answer:
a) k = 2/5
b) y = 2/5x
c) y = 2 3/5
Step-by-step explanation:
<h3>a)</h3>
The proportional relation is described by the equation ...
y = kx . . . . . . k is the constant of proportionality
The value of k can be found by dividing the equation by x:
y/x = k = (2 1/4)/(5 5/8) = (9/4)/(45/8) = 18/45
k = 2/5
__
<h3>b)</h3>
As above, the equation is ...
y = kx
y = 2/5x
__
<h3>c)</h3>
Using 6.5 for x, we have ...
y = (2/5)(6.5) = 2.6 = 2 3/5
Answer:
y=3x-9
Step-by-step explanation:
It will be right angle triangle. The two vectors beginning at the same vertex
of a triangle are <2,3> and <-3,2> is classified as right-angled
triangle. It is classified as a right-angled triangle because the dot product
of the vectors are 0.
Log₄(y+2) = 3, transform it into exponent form:
(y+2) = 4³
y+2 = 64
y= 62
Each term after the first is obtained by multiplying the previous one by -3 so the answer is -81 , 243
