Answer:
Step-by-step explanation:
Answer:
must be greater than 7
Step-by-step explanation:
using pythagoras theorem
a^2=b^2-c^2
x^2=15^2-12^2
x^2=225-144
x^2=81
take square root both sides
√x^2=√81
x=9
and 9 is greater than 7
Hey there! :)
Answer:
The first option:
Y-intercept: 9
Zeros: 1, -1, 3, -3
Step-by-step explanation:
The Y-intercept is where the graph intersects with the y-axis. On this graph, we can see that the graph intersects at y = 9.
The zeros of the graph are where the graph intersects the x-axis. When looking at the graph, the x-axis is intersected at x = -3, x = -1, x = 1, and x = 3.
Therefore, A, or the first option, is the correct answer.
