Answer:
9.1 x 10² = 910
9.1 / 10² = 0.091
Step-by-step explanation:
N x 2 = 12 + 5n
2n - 5n = 12

3n = -12
n = -4
Hello!!
Well, the x-intercept is found when y = 0, so plug in y = 0:
-7x + 3(0) = 21
-7x = 21
x = -3
Therefore, the x-intercept of -7x + 3y = 21 is -3.
Hope this helps!! Let me know if you have ANY questions.
