Answer:
B
Step-by-step explanation:
all the equations start with y = 2x so all the graphs will paralel but because every single equation has different constant number, it will result different y-interceps.

Answer:
The second statement is true.
Step-by-step explanation:
Draw the corresponding parabola and use it to verify all statements.
Answer:
15 because it says -(-2) so that means it is negative in something so your answer will be 15
Step-by-step explanation:
4) 41% of 78 is what?
Answer = 31.98
Work:
x = 41/100 x 78
x = 3198/100
x = 31.98
6) 58% of what is 63.4?
The number is = 109.31
Explanation:
Let the number be = x
58/100 (x) = 63.4
x = 63.4 x (100/58)
x = 6340/58
x = 109.31
First, expand the brackets on the left hand side.
You have: 8x-6=4x-78
Minus least number of x first on each side, so minus 4x
2x-6=-78
Then add 6 to both sides
2x= -72
Then divide both sides by 2 to get x on its own
X= -36
(-72/2=-36)
