Answer:
$3.40
Step-by-step explanation:
4x.40 is 1.60
2x.90 is 1.80
Then you take 1.80+1.60 to get $3.40 Hope this helps!

d) The amount of radium after 300 years is:
Jody invested less in an account paying simple interest than she did in an account paying simple interest. At the end of the first year, the total interest from both accounts was Find the amount invested in each account.
Exponent form : 6^5
explanation :
we are given five 6's , so we simply start out with the number that is being multiplied over and over again .
which in this case , is 6.
6 • 6 • 6 • 6 • 6 = 7776
To make things easier though, we write repetitive numerals in exponent form. You will still get the same answer either way .
6^5 = 7776
answer : 6^5
<h3>Answer: Draw a straight line through (0,-7) and (1,-5)</h3>
Explanation:
You could use any two points you want. For me, the easiest is when x = 0. Plug this into the equation to get
y = 2x-7
y = 2(0)-7
y = -7
So we have x = 0 and y = -7 pair up to get (0,-7) as our first point. This is the y intercept.
Repeat for x = 1
y = 2x-7
y = 2(1)-7
y = -5
So (1,-5) is another point on this line. You only need two points at minimum to graph a straight line.
