The solutions of a quadratic equation are 5 and -1. What is the factored form of a related quadratic function?

Alecsey [184]

Answer:

Step-by-step explanation:

Given the solutions of a quadratic, say x = a, x = b then the factors are

(x - a) and (x - b) and the function is the product of the factors, that is

f(x) = (x - a)(x - b)

Here the solutions are x = 5 and x = - 1, thus the factors are

(x - 5) and (x - (- 1)), that is (x - 5) and (x + 1), thus

f(x) = (x - 5)(x + 1) → A

Answer:

$y=6,850x - 13,456,500$

Step-by-step explanation:

To find the linear model, we need to find a linear equation, where its slope is defined as

$m=\frac{y_{2} -y_{1} }{x_{2}-x_{1} }$

So, we use the given points (1970, 38000) and (1990, 175000), to find the slope

$m=\frac{175,000-38,000}{1990-1970}=\frac{137,000}{20} =6,850$

Now, we use the point-slope formula to find the equation

$y-y_{1} =m(x-x_{1} )\\y-38000=6850(x-1970)\\y=6850x-13,494,500+38,000\\y=6,850x - 13,456,500$

Therefore, the linear model is

$y=6,850x - 13,456,500$

Question 9 of 15 (1 point)

mote1985 [20]

The number is -9

Step-by-step explanation:

Let x be the number then according to given statement

$4x+10 = x-17$

Subtracting 10 from both sides

$4x+10-10 = x-17-10\\4x = x-27$

Subtracting x from both sides

$4x-x = x-x-27\\3x = -27$

Dividing both sides by 3

$\frac{3x}{3} = \frac{-27}{3}\\ x = -9$

<u>Verification:</u>

$4(-9)+10 = -9-17\\-36+10=-26\\-26=-26$

The number is -9
