Answer:
360
Step-by-step explanation:
If x is gallons of 70% antifreeze solution, then:
0.70x + 0.20(90) = 0.60(x + 90)
0.70x + 18 = 0.60x + 54
0.10x = 36
x = 360
The slope of the line is .75, so 1. is false.
The graph is a dashed line AND the area above it shaded, so 2. is false (in and of itself)
The graph is the area shaded above the line not below it, so 3. is false.
0>.75(0)-2, 0>-2 so 4. is TRUE
The line is dashed and is not part of the solution to the inequality, so the point (0,-2) while on the line, is not part of the solution set and thus is not part of the graph, and does not intercept the graph, so 5. false. (the line intercepts the y axis at (0, -2) but the line itself is not part of the solution set and thus is not part of the graph)
So only statement 4. is true.
Answer:
5
Step-by-step explanation:
-5 - (-10)
Here we have to use sign of multiplication rule.
negative * negative = positive
that is, -(-) = +
We use this rule and simplify.
- (-10) = + 10
Therefore, -5 + 10
When we have different sign of the numbers, we have to subtract from greatest to least number, then put the largest number sign in the answer.
-5 + 10 = + 5
Hence, the answer is 5
Hope this is will help you.
Thank you.
Answer:
The answer is the IRA
Step-by-step explanation:
If he takes out 2% from each account, the highest penalty will be for the IRA account which is, 6% of 62,000 is $3,720. He will also take 2% of that 62,000 which will be $1,240. The total will be $4,960.
For the 401k account the withdrawal is $1,500 and the penalty is $3,000. That is $460 less than the IRA account.
I hope this answer helps.
