Answer:
59
Step-by-step explanation:
The answer is 59 because when you add 24 and 7 it is 31 and 31 +59 makes a 90° angle.
The answer is the last choice since in a function, x values in the coordinates cannot repeat themselves. In the first answer, the x-value 2 has more than one y-value meaning it cannot be a function. In the second answer, the x-value -2 also repeats itself and has more than one y-value, and in the 3rd choice, the x-value 5 also repeats.
Answer:
7
Step-by-step explanation:
f(-1)=-1*(-1)*2-3*(-1)+2 → f(-1)=2+3+2 → f(-1)=7
You can easily add while numbers but with decimals, if the point is put in the wrong place then you’ll change the entire number
Answer:
The first equation answer would be 70, whilst the second equation's answer is 160. I think this would be the correct answer:
20(2) + 30(1) = 70.
20 (8) + 30(0) = 160.
Step-by-step explanation:
Basically, you would do 20(2) + 30(1) for one of the equations and 20(8) + 30(0) for the other equation. Those equations would give you the answer.
