f(x) is a polynomial of degree 4 with real coefficients; two of its zeros are -3 (with a multiplicity of one) and 4 - i . How ma
ny x-intercepts does f(x) have? Explain how you know using complete sentences. Make sure your explanation is convincing and thorough.
1 answer:
Answer:
Step-by-step explanation:
complex zeros always occur in pairs.
so zeros are -3,4-i,4+i
so fourth zero also intersects x-axis.
Hence there are two x-intercepts only.

Answer:
25 ≥ 0.90b + 2m
Step-by-step explanation:
Given:
Cost of each banana = $0.90
Cost of each mango = $2
Total amount = $25
Find:
Inequality
Computation:
Assume;
Number of banana = b
Number of mango = m
Total amount ≥ Cost of total banana + Cost of total mango
25 ≥ 0.90b + 2m
Answer:
-3
Step-by-step explanation:
To find the slope given two points
m = (y2-y1)/(x2-x1)
= (-5-7)/(-4- -8)
= (-12)/(-4+8)
=-12/4
= -3

Step-by-step explanation:=1/9
4x + 3y = 9
4x - 4x + 3y = -4x + 9
3y = -4x + 9
3 3
y = -1¹/₃x + 3
