Answer:
x = 4.56
Step-by-step explanation:
57 + x + 25x + x = 180
27x + 57 = 180
27x = 123
x = 4.56
Double means times 2.
Product means multiplication.
So the answer is 2(4*7)
Answer:
Degree = 4
Step-by-step explanation:
For the given conditions:
n = 4
i and 5i are zeros
f(-2) = 145
For zeros, it means they are a quadratic factor of the expression
It means, we will have x = ± i and x = ± 5i
therefore, the given factors are (x - i)(x + i)(x - 5i)(x + 5i)
Hence, we have the function
given degree = 4
f(x) = a(x-i)(x+i)(x-5i)(x+5i)
f(x) = a(x² + 1)(x² + 25)
Hence, substituting -2 for x, we have
f(-2) = a(5)(29) = 145
Hence, a = 1
f(x) = x⁴ + 26x² + 25
Therefore, we can see that the given degree = 4
20y+30x=1000 divide 20 on each side to st the y alone.
y+30x=50 next put it in slope intercept form
y=30x+50 I don't know if this was te answer you were looking for but I hope it is
