What equation is equivalent to x2 + 20x + 81 = -27? Can you show me how you got the answer please

Alla [95]

The equivalent equation is x² + 20x = -102

<h3>Simplification of quadratic equation</h3>

The equivalent equation can be obtained by factorizing or simplifying the given quadratic equation as shown below;

x² + 20x + 81 = -21

<em>collect similar terms together</em>

x² + 20x + 81 + 21 = 0

x² + 20x + 102 = 0

The equation can also be written as x² + 20x = -102

Thus, the equivalent equation is x² + 20x = -102

A survey showed that 35% of the students prefer plain white milk over chocolate milk. If the school has 1200 students. How many

vodomira [7]

Answer:

The number of students who prefer chocolate milk is 780 .

Step-by-step explanation:

Given as :

The total number of students in the school = 1200

The percentage of students who prefer plain white milk = 35 %

Let the number of students who prefer chocolate milk = x

Now, ∵ The percentage of students who prefer plain white milk = 35 %

∴ The percentage of students who prefer chocolate milk = 100 % - 35 % = 65%

So , As The number of students who prefer chocolate milk = x

Or, 65 % of total number of students in school = x

So, x = $\frac{65}{100}$ × 1200

or, x = $\frac{65\times 1200 }{100}$

∴ x = 780

So, the number of students who prefer chocolate milk = x = 780

And students who prefer plain white milk = 1200 - x = 1200 - 780 = 420

Hence, The number of students who prefer chocolate milk is 780 . Answer

Question 4 (1 point) Determine whether the ordered pair (3,28) is a solution to the equation 2x- y/2 = -8 (3, 28) Is a solution

bulgar [2K]

Answer:

It is a solution

Step-by-step explanation:

Given

$2x - \frac{y}{2} = -8$

Required

Determine if $(3,28)$ is a solution

$(3,28)$ implies that:

$x = 3$

$y = 28$

To check if it is a solution, we simply substitute values for x and y in the given equation;

$2x - \frac{y}{2} = -8$

$2(3) - \frac{28}{2} = -8$

$6 - 14= -8$

$-8= -8$

Since both sides of the equation are equal; then, Yes, it is a solution
