Y = 5x + 3
when x = 4
y = 5(4) + 3 = 23
Answer (4,23)
It by root you mean radical equations, well then I can’t help you there, as there is too much stuff to cover.
If you mean zeros, then to find the root of a function you just find the zeros.
Answer: Choice C)
We start at 0 and move 1.4 units to the right. Then we move another 2.3 units to the right to land on 3.7
Notice how 1.4 - (-2.3) = 1.4 + 2.3 = 3.7
Answer: B. 31
Step-by-step explanation:
This linear regression was constructed by relating the hours practiced per week and the number of competitions won.
Going by this graph, the number of competitions they can expect to win at 5 practices a week is 31.
This is derived by looking for the point where 5 competitions on the x-axis intersects with the line. This point is at 31 competitions on the y axis which would make it the answer.
