Answer:
82
Step-by-step explanation:
For this problem you would first round everything. 9.03 becomes 9, 19.87 becomes 20, 3.11 becomes 3 and 4.97 becomes 5. You then just do the problem. 9 + 20 = 29, multiplied by 3 makes 87, 87 - 5 = 82.
She made the mistake in step 4
She should have divided by -2 not just 2 alone
x = -1
y = 1
To find this, input the equation into a graphing calculator, whether online or an actual one, and you have two options:
1 - Search for the points in which the line crosses the x and or y axis.
2 - Hit 2nd Graph to access the table and find when x and y equal zero.
Hope this helps!
Answer:
The first statement is incorrect. They have to be complementary.
Step-by-step explanation:
You can't say the measure of angle B is congruent to theta because it is possible for angles in a right triangle to be different.
You can only say that what he said is true if the angle was 45 degrees, but based on the information provided it is not possible to figure that out.
The other two angles other than the right angle in a right triangle have to add up to 90 degrees, which is the definition of what it means for two angles to be complementary. A is the correct answer.
Since we are looking for the principal amount, then all we have to do is reverse the process of getting the amount of tax. In order to get the principal, you just have to divide 22 with 0.05. The answer is 440 so that is the principal amount you are looking for.
