Answer:
77 degrees c:
Step-by-step explanation:
5y-5y^2-5+2+2y+3y^2-1
collect like terms
7y-2y^2-4
reorder the terms
-2y^2+7y-4
-2y^2+7y-4 is your final answer, I hope this helps!
Answer:
60
Step-by-step explanation:
Multiply length times width times height
To easily find the slope and y intercept of the line, put it in slope intercept form by rearranging the variables around.
6x-7y = 2
6x - 7y + 7y = 2 + 7y
6x = 7y + 2
6x - 2 = 7y + 2 - 2
7y = 6x - 2
7y/7 = 6x/7 - 2/7
Y = 6/7(X) - 2/7
Y = 6/7x - 2/7
Slope = m = 6/7
Y intercept = b = -2/7
(0, -2/7).
4 * 2 + (10 - 12)
Using PEMDAS, we solve inside the parentheses first.
10 - 12 = -2
If it was 12 - 10, the answer would be 2. But because 10 is on the left side, the answer is -2
Next, we have 4 * 2.
4 * 2 = 8
And finally, 8 + (-2) = 6.
Because we're adding a negative number, it subtracts from the positive number.
