Answer:
x= -9.5
Step-by-step explanation:
We want to find out what the variable, x, is equal to. Therefore, we must isolate the variable on one side of the equation.
-4.75 = x/2
x is being divided by 2. The inverse of division is multiplication. Multiply both sides of the equation by 2.
2*(-4.75) = (x/2)*2
2*(-4.75)=x
2* -4.75=x
Multiply 2 and -4.75
-9.5=x
Let's check our solution. Plug -9.5 back in for x and solve.
-4.75= x/2
-4.75= -9.5/2
-4.75= -4.75
This checks out, so we know our solution is correct.
x is equal to -9.5
Answer:
Step-by-step explanation:
First convert the decimal to an improper fraction
That's
So we have
Cross multiply
4x = - 38
Divide both sides by 4
We have the final answer as

b. f(x) = (x – 7) (x – i) (x – 5) (x + i)
c. f(x) = (x – (7 – i)) (x – (5 + i)) (x – (7 + i)) (x – (5 – i))
d. f(x) = (x + (7 – i)) (x + (5 + i)) (x + (7 + i)) (x + (5 – i))
The polynomial function with a leading coefficient of 1 and roots (7 + i) and (5 – i) with multiplicity 1 is f(x) = (x + 7) (x – i) (x + 5) (x + i).
The polynomial function with a leading coefficient of 1 and roots (7 + i) and (5 – i) with multiplicity 1 is option a. f(x) = (x + 7) (x – i) (x + 5) (x + i). To understand why this is the correct answer, we first need to know that complex roots always appear in conjugate pairs, which means that if a + bi is a root, then a - bi is also a root. The given roots are (7 + i) and (5 – i), so the conjugate pairs are (7 – i) and (5 + i).
Therefore, the correct polynomial is obtained by multiplying the factors (x – (7 + i)), (x – (7 – i)), (x – (5 + i)), and (x – (5 – i)). This gives us f(x) = (x + 7) (x – i) (x + 5) (x + i), which is option a.
