The point (2, -7) is reflected across the x-axis.
What are the coordinates of the image of the point?

Answers

Answer: need more information

Step-by-step explanation: ....

The image of the point (2, -7) after reflection across the x-axis is (2, 7).

What is Reflection?

In mathematics, reflection is a transformation that flips a figure over a line or plane. The line or plane is called the axis of reflection, and each point of the figure and its image are equidistant from the axis of reflection.

We have the coordinates as (2, -7).

Now, the rule for reflection across x- axis is

(x, y) -> (x, -y)

When a point is reflected across the x-axis, its y-coordinate is negated.

Therefore, the image of the point (2, -7) after reflection across the x-axis is (2, 7).

Find all solutions to the equation $x^2 - 7x = 30$. If you find more than one, then list the values separated by commas. If the solutions are not real, then they should be written in $a + bi$ form.

Answers

Answer:-3, 10

Step-by-step explanation:

Subtracting 30 from both sides gives x^2 - 7x - 30 = 0. The quadratic factors as

(x - 10)(x + 3) = 0, so the solutions are x = 10 and x = -3.

Instead of factoring, we also could have applied the quadratic formula with a = 1, b = -7, and c = -30:

The solutions to the equation x² - 7x = 30 are -3 and 10.

What is a solution?

Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.

We have,

x² - 7x = 30

x² - 7x - 30 = 0

Middle-term factorization.

x² - (10 - 3)x - 30 = 0

x² - 10x + 3x - 30 = 0

x(x - 10) + 3(x - 10) = 0

(x + 3) (x - 10) = 0

x + 3 = 0

x = -3

x - 10 = 0

x = 10

Thus,

The solutions are -3 and 10.

Elsa took out a 2-year loan to buy a car at a 6% simple interest rate.

A. If she has to pay a total of $264 in interest, how much principal did she borrow to pay for the car?

B. How much did she end up paying for her car altogether?

Answers

Step-by-step explanation:

P = I / rt is the formula we're going to use.

P is the principle (which is what we're solving for)

I = the interest accrued over the specified amount of time (2 years)

r = the interest rate (6%)

t = the time specified (2 years)

Change the percent to a decimal. Place the decimal two places to the left to make 0.06.

P = 264 / 0.06(2)

P = 264 ÷ 0.12 = 2,200

Principal borrowed would be $2,200

A store manager combines trail mix that is 30% raisins with a trail mix that is 55% raisins. He makes 800lb of trail mix that is 40% raisins. How many pounds of each trail mix does the manager use?

Answers

Answer:

320 pounds of 55% raisins trail mix

480 pounds of 30% raisins trail mix

Step-by-step explanation:

Sorry, I can’t write how I got the answer. We just did it in class and decided to help... (Btw, sorry if I’m too late)

The store manager mixed 320 pounds of 55% raisins trail mix and 480 pounds of 30% raisins trail mix.

Given that,

A store manager combines a trail mix that is 30% raisins with a trail mix that is 55% raisins.

He makes 800lb of trail mix that is 40% raisins.

We have to determine,

How many pounds of each trail mix does the manager use?

According to the question,

Let, x = pounds of trail mix 30% raisins

y = pounds of trail mix 55% raisins

The distributor wants to make 800 pounds of trail mix, thus:

x + y = 800  

The mix must be 40% raisings as a combination of x and y, thus:

30x + 55y = 40 × 800

30x + 55y = 32,000

Divided by 5 the equation

6x + 11y = 6400

Solving both the equation

[tex]x + y = 800\\\\x = 800 -y\\[/tex]

Substitute the value of x in equation 2,

[tex]6x + 11y = 6400\\\\6 (800-y) + 11y = 6400\\\\4800 - 6y +11y = 6400\\\\5y = 6400-4800\\\\5y = 1600\\\\y = \dfarc{1600}{5}\\\\y = 320[/tex]

Substitute the value of x in equation 1

[tex]x + y = 800\\\\x + - 800 -y\\\\x = 800-320\\\\x = 480[/tex]

Hence, The store manager mixed 320 pounds of 55% raisins trail mix and 480 pounds of 30% raisins trail mix.

How I found it:

Converting 7 and 2.3 into a decimal with the decimal place two to the left.

7 becomes 0.07

2.3 becomes 0.23

I added this to the kilometers traveled by train(which is 19.955km).

19.955km + 0.023 + 0.07 = 19.985

19.985 being the value for answer A.
