Answer:
$400 and $1,000
Step-by-step explanation:
Let us assume the x be the amount invested in 7% account
And, 600 + x be the amount invested in 9% account
Now the equation is
7x% + 9%(600 + x) = $118
0.07x + 54 + 0.09x = $118
0.16x = $118 -$54
0.16x = $64
x = $400
And, the other one is = $400 + $600 = $1,000
<h2><u>
Answer:</u></h2>
y = cos ^- 1 (x)
Step-by-step explanation:
The Function y = cos -1x = arccos x and its Graph: Since y = cos -1x is the inverse of the function y = cos x, the function y = cos -1x if and only if cos y = x. This leaves the range of the restricted function unchanged as [-1, 1].
