x2 + 8x + 19 = 0
What’s the answer ? Math algebra 2

Answers

Answer: x= 4 ± [tex]\sqrt{-3}[/tex]

Step-by-step explanation:

[tex]x^{2}[/tex] + 8x + 19 = 0     First subtract 19 from both sides

             -19    -19

[tex]x^{2}[/tex] + 8x           =  -19    Now to complete the square on the left side you will divide 8 by 2 and square the number that you will get and add it to both sides. If you divide 8 by 2 you get 4 and  4 squared is 16 .So add 16 to both sides.

x^2 + 8x + 16 = -19 + 16  Now factor the left side

(x+4)^2 = -3    Take the square root of both sides

(x+4) = ±[tex]\sqrt{-3}[/tex]        

Subtract 4 from both sides

x = ±[tex]\sqrt{-3} - 4[/tex]

The formula a = m – n represents the actual cost, a, of an item with original price m after a coupon for n dollars off is applied. Solve the formula for the amount of the coupon n. A. n = a + m B. n = m – a C. n = a – m D. n = – m – a

Answers

Answer:

n = m - a

Step-by-step explanation:

Given that:

The expression of the formula  a = m - n

where;

a = actual cost of an item

m = original price

n = amount of coupon in dollars

The objective is to solve for the amount of the coupon.

In order to determine the amount of the coupon, we need to make n which is the amount of coupons in dollars the subject of the formula from the given expression.

So if a = m - n

a + n = m

n = m - a

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The correct option is C.

What is a line segment?

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. A line segment is a straight line with finite length, and thus, has two endpoints(points on either end).

The diagram for the given condition can be made as shown below. Now, from the image, the following conclusion can be made,

The two lines w and n are parallel to each other.The line m is perpendicular to n, this is because the angle between the two lines is equal to 90°. The two lines k and line n are also parallel to each other.

Further, if all the options are observed.

A.) k Parallel to n and w Perpendicular to m

The first half of the given statement is correct but the second half of the equation is completely wrong. Therefore, not the correct option.

B.) k Parallel to n and w Perpendicular to m

The first half of the given statement is correct but the second half of the equation is completely wrong. Therefore, not the correct option.

C.) w Parallel to n and n Perpendicular to m

Since both the parts of the statement are correct, therefore, it can be concluded that the given statement is correct.

D.) w Parallel to n and w Perpendicular to m

The first half of the given statement is correct but the second half of the equation is completely wrong. Therefore, not the correct option.

Estimate the number of school-aged children in the city where the population is approximately 60,000, if 1 of every 10 citizens is a school-aged child. If 500 children can attend each school, about how many schools will the city need?​

Answers

1 out of 10 are school aged.

Divide total population by 10:

60,000 / 10 = 6,000 are school aged.

Each school holds 500, divide school aged by 500:

6,000 / 500 = 12

They would need 12 schools.

The number of schools the city with the population 60,000 requires are 12.

Given that, the number of school-aged children in the city where the population is approximately 60,000.

In population 1 out of 10 are school aged.

Divide total population by 10

60,000/10 = 6,000 are school aged

Each school have 500 children, so the number of schools are

6,000/500 = 12

Therefore, the number of schools the city needs are 12.
