The value of k should be 2.
if you plug the y value of the point in the equation for y and do the same with x you should be able to get this answer after fallowing the order of operation.
Answer:
a)
Step-by-step explanation:
On the x-axis, y = 0
y = -3x -18
0 = -3x -18
3x = -18
x = -6
(-6,0)
Answer: 118
Step-by-step explanation: if x=4 then 4x3 to the 2nd power= 144. 13x2=26
144-26=118
Answer: x = 3
Step-by-step explanation:
2(7x - 6) = 30
14x - 12 = 30
+ 12 +12
14x = 42
/14 /14
x = 3
