Answer: Value of m = 9
Step-by-step explanation:
Given that the relationship between Q and m is;
Q = 17m
Make m the subject of formula
M = Q/17
If Q is greater than 150 and less than 160, then, let assume that
Q = 151, then
M = 151/17
M = 8.88
If Q = 159
M = 159/17
M= 9.35
Since m ranges from 8.88 to 9.35, the value of m = 9
Answer:
Gain = S.P - C.P
Loss =C.P - S.P
where, S.P equals spelling price
and C.P equals cost price

He messed up step 2 he added instead of multiplying
<span>y= 2x ^2 - 8x +9
</span>y = a(x - h)2 + k, where (h, k) is the vertex<span> of the parabola
</span>so
y= 2x ^2 - 8x + 9
y= 2x ^2 - 8x + 8 + 1
y = 2(x^2 - 4x - 4) + 1
y = 2(x - 2)^2 + 1 ....<---------<span>vertex form</span>
