Solve the following equation using the quadratic formulax^2-8x 97 = 0
The answer choices are in the picture

Answers

Answer:

Option B

$x=4+9i$ and $x=4-9i$

Step-by-step explanation:

we have

$x^(2) -8x+97=0$

The formula to solve a quadratic equation of the form $ax^(2) +bx+c=0$ is equal to

$x=\frac{-b(+/-)\sqrt{b^(2)-4ac}} {2a}$

in this problem we have

$x^(2) -8x+97=0$

$a=1\nb=-8\nc=97$

substitute in the formula

$x=\frac{-(-8)(+/-)\sqrt{-8^(2)-4(1)(97)}} {2(1)}$

$x=\frac{8(+/-)√(-324)} {2}$

Remember that

$i^(2) =-1$

$i=√(-1)$

$x=\frac{8(+/-)18i} {2}$

$x=\frac{8(+)18i} {2}=4+9i$

$x=\frac{8(-)18i} {2}=4-9i$

Final answer:

To solve the equation x^2 - 8x + 97 = 0 using the quadratic formula, substitute the coefficients into the formula and simplify the expression. In this case, the equation has no real solutions.

Explanation:

To solve the equation x^2 - 8x + 97 = 0 using the quadratic formula, first identify the coefficients in the equation. The quadratic formula is given by x = (-b ± sqrt(b^2 - 4ac)) / (2a). In this case, a = 1, b = -8, and c = 97. Substitute these values into the quadratic formula and simplify the expression to find the value(s) of x.

Using the quadratic formula, we have x = (-(-8) ± sqrt((-8)^2 - 4(1)(97))) / (2(1)). Simplifying further, we get x = (8 ± sqrt(64 - 388)) / 2. Continuing the simplification, we have x = (8 ± sqrt(-324)) / 2. Since the square root of a negative number is not a real number, the equation has no real solutions.

Therefore, the answer is that there are no real solutions to the equation x^2 - 8x + 97 = 0.

Hey There!

Whenever you subtract, remember you have to subtract from left to right. Also remember the process of regrouping, this also means to take away from tens. So whenever a number can't subtract you simply regroup it.

Tom and his brother caught 100 fish on the weeklog fishing trip. the total weight of the fish was 235 pounds. Part C:
supposethe total weight of the fish caught staying the same but instead the of 100 fish caught during the week log fishing trip, only 10 fish were caught. How would the weight of each fish change? Explain.

Answers

Instead of 100 fish caught during the week-long fishing trip, only 10 fish were caught. Then the weight of ten fish will be 23.5 pounds.

What is a Linear system?

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side byside.

Given

Tom and his brother caught 100 fish on the week-long fishing trip.

The total weight of the fish was 235 pounds.

How to find the weight of each fish change?

Tom and his brother caught 100 fish on the week-long fishing trip. The total weight of the fish was 235 pounds.

Then the weight of one fish will be 2.35 pounds.

Suppose the total weight of the fish caught staysthe same but instead of 100 fish caught during the week-long fishing trip, only 10 fish were caught.

Then the weight of ten fish will be 23.5 pounds.

Thus, the weight of ten fish will be 23.5 pounds.

The weight of 10 fish would be 23.5 pounds. If 100 fish is 235 pounds, then each fish is 2.35 pounds. 10 fish of that same weight would be 23.5 pounds.
