C. 8.7 x 102
8.7 x 102= 887.4
Which is the largest product out of all the other equations.
Hope this helps!
So x + y = 45, and 4x + 5y = 195. Get y by itself. Subtract x from both sides in the first equation to get y = 45 -x, and subtract 4x from the second equation to get 5y = 195 - 4x. Divide by 5 to both sides to get y = 39 - 4/5x. 39 - 4/5x = 45 - x. Add x to both sides to get 39 - 1/5x = 45. Subtract 39 from both sides to get -1/5x = 6. Divide by -1/5 to get x = -30, or 30. In the first equation, do 30 + y = 45. Subtract 30 from both sides to get y = 15. Check. 4(30) + 15(5) = 195, or 120 + 75 = 195.
The answer is B) x^3-1 because it's the only one with the 3rd degree
Answer:
(16,-1)
Step-by-step explanation:
When grades are expressed as a quantity of 1, such as two feet per second or 5 miles per hour, they are called unit rates.
