3 = 10 because it makes sense
Answer:
0.375 is the correct answer
Answer:
You do -17 + -10 inorder to change the operation used because both negatives does not mathematically look nice.
Step-by-step explanation:
To isolate the unknown, we need to move all the numbers on one side of the equal sign and all the unknow variables on one side.
Here we move 10 on the other side by taking away 10 both sides
10 + 3x = -17
-10 -10
then we are left with only 3x on one side and -27 on the other side because -17 - -10 = -27 , in this case it is acknowledge to change the operation from minus to add because the two minus are together, so we say -17 + -10 .
3x = -27
/3 /3
x = -9
Answer:
its times 3
Step-by-step explanation:
Answer:
Y=3x+14
Step-by-step explanation:
For perpendicular lines they have gradients which are recipricol to one another and -ve
E.g 1/3 gradient of perpendicular line is-3
Gradient of the perpendicular line is 3
Y-2/x--4=3
Y-2=3(x+4)
Y-2=3x+12
Y=3x+12+2
Y=3x+14
