Let's assume, for simplicity, that there were 100 questions in the test: a score of 80% means you got 80 right and (100-80)=20 wrong.
The ratio is then 80 to 20 or
80:20.
you can also simplyfy it, by dividing both numbers by 20:
4:1
which I think is the best way to give the answer!
Answer:
The answer to your question is (-1, 2)
Step-by-step explanation:
Data
y = -4x - 2 Equation l
y = 2x + 4 Equation ll
Process
-Graph equation l (green line)
Plot the point (0, -2)
Starting from this point plot the point (1, -4), this point comes from the slope.
-Graph the equation ll (blue line)
Plot the point (0, 4)
Plot the point (1, 2) starting from the previous point.
-The solution is the point where the lines cross. This point is (-1, 2)
Answer:
A. 5
Step-by-step explanation:
because 13 is the hypotenuse and 8 is the sine
Using multiplication signal rules, it is found that:
A: Emma's statement is always false.
B: The result is always negative.
C: Emma's statement is always true.
The rule used for this exercise is as follows:
- When two numbers of different signals are multiplied, the result is negative.
- When two numbers have the same signal, the result is positive.
Part A:
- Three numbers are multiplied, all negative.
- The multiplication of the first two result in a positive number.
- Then, this positive number is multiplied by a negative number, and the result will be negative, which mean that Emma's statement is always false.
Two examples are:


Part B:
The rule is that the result is always negative.
Part C:
- The multiplication of the first two negative numbers result in a positive number.
- Then, this positive number is multiplied by another positive number, and the result will be positive, which mean that Emma's statement is always true.
Two examples are:
