Answer:
all I know is how to get y but y=122
Step-by-step explanation:
y=3(40)+2
y=120+2
y=122
sorry but I dont know what to do for x
Answer:
120
Step-by-step explanation:
Slope = rise / run
1/20 = 6 / run
run = 120
Answer:
40/100 = .4 = 40%
Step-by-step explanation:
Both of your answers are correct. In the first equation, if you were to substitute 3 for x, because you have to do exponents first, you have 3^2, which is 9, and 9*6 =54. If you were to substitute -3 for x again you would have to do the exponents first which would be -3^2 which is 9, and 9*6 = 54.
For the second question, if I substitute 0.75 for t, I get -9 + 18 + 7. This is equal to 16, and therefore the answer would be D. Hope this helps! :D. Let me know if you have questions about my explanation, and feel free to post more questions.
The answer would be the third one .
Perpendicular would always be the opposite of your original slope.
Hope this helps! (:
