Solution: Let x be the amount to be invested (15%).
Then,
x*0.15 + 550*0.11 = (x+550)*0.12
x*0.15 - x*0.12 = 550*0.12 - 550*0.11
0.03x = 550*(0.12-0.11)
0.03x = 550*0.01
0.03x = 5.5
x =5.5÷0.03
x=183.33
Answer: $183.33 more to be invested for 12 % total return.
Answer:
Step-by-step explanation:
Consider -7-4r=-15. Adding 7 on both sides of the equation,
-4r=-8 --- r = 2
Plug in value of r in r/2 + 9 = 2/2+9 = 1+9 = 10
The correct option regarding whether the graph shows a function is given by:
C. Yes; the graph passes the vertical line test.
<h3>When does a graph show a function?</h3>
In a function, one value of the input can be related to only one value of the output. Hence, in a graph, it means that for each value of x(horizontal axis), there can only be one respective value of y(vertical axis), which will mean that the graph will pass the vertical line test.
In this problem, the condition is respected, hence option C is correct.

y + 3 = 
(x - 5)
the equation of a line in point- slope form is
y - b = m ( x - a )
where m is the slope and (a, b) a point on the line
here m = and (a,b) = (5 , - 3 )
y + 3 = (x - 5 ) ← in point-slope form
