The solutions to a certain quadratic equation are x= -4 and X = 3. Write the equation in standard form below.

SCORPION-xisa [38]

Answer:

x² + x - 12 = 0

Step-by-step explanation:

If x = -4 and x = 3 are solutions to a quadratic equation, then

(x + 4)(x - 3) = 0

Expand the brackets: x² - 3x + 4x - 12 = 0

Combine like terms: x² + x - 12 = 0

Answer:

third option

Step-by-step explanation:

m(n(x)) =

$\frac{x - 3 + 5}{x - 3 - 1} = \frac{x + 2}{x - 4}$

the domain of this is R/(4)

so as the third option

Answer:

The second choice is correct

Step-by-step explanation:

Go to a point like 4,3 and 0,1. the difference in x is 4 since 4-0 = 4.

4,3 and 0,1 now we find the change in y, 3-1 which is 2. the formula for slope is change in y over change in x so 2/4 is the slope or 1/2.

The y intercept of the line is 1 since the line touches the y-axis at the y, 1.

therefore the equation is y = 1/2x + 1.

Bernie played 3 rounds of golf, and the mean of his score was 78. If his lowest score was 74, what is the greatest possible valu

zmey [24]

Answer:

85.

Step-by-step explanation:

Let x represent Bernie's highest score.

We have been given that Bernie played 3 rounds of golf, and the mean of his score was 78. His lowest score was 74.

Since Bernie's lowest score is 74, so we can assume that his score on 2nd round would be 75.

Now, we will use mean or average formula to solve our given problem.

$\text{Mean}=\frac{\text{Sum of all data points}}{\text{Number of data points}}$

$78=\frac{74+75+x}{3}$

Let us solve for x.

$78\cdot 3=\frac{74+75+x}{3}\cdot 3$

$234=74+75+x$

$234=149+x$

$x=234-149$

$x=85$

Therefore, the greatest possible value of his highest score would be 85.
