Answers

Answer 1

Answer:

The answer is below

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation is rotation, reflection, translation and dilation.

If a point  (x, y) is rotated 90° counterclockwise, its new coordinate is (–y, x).

Give point M (3, –6) is rotated 90° counterclockwise:

Step 1: Interchange the x- and y-coordinates to get (-6, 3)

Step 2: Multiply the new x-coordinate by –1 to get (-6(–1), 3)

Step 3: Simplify to get (6, 3)

Therefore she made an error in step 1

To rent a building for a school dance Ava paid 120$ plus 2.50 for each student who attended if she paid a total of $325 how many students attended the dance

Answers

Answer:

82

Step-by-step explanation:

Answer:

82

Step-by-step explanation:

The first thing you do here is subtract 120 from 325

325-120=205

The next step is to divide 205 by 2.50 to find how many students attended

205/2.50=82

Therefore 82 students paid the $2.50 price to attend the dance

Which inequality correctly compares Three-fourths, One-seventh, and Five-sixths? One-seventh < Three-fourths < Five-sixths One-seventh < Five-sixths < Three-fourths Three-fourths < Five-sixths < One-seventh Three-fourths < One-seventh < Five-sixths

Answers

Answer:

The inequality which correctly compares Three-fourths, One-seventh, and Five-sixths is : One-seventh < Three-fourths < Five-sixths.

The first option is correct.

Step-by-step explanation:

To determine which inequality correctly compares Three-fourths, One-seventh, and Five-sixths, we will arrange them in ascending order.

To do this, first, we will determine the LCM of the fractions denominators..

Three-fourths, One-seventh, and Five-sixths

[tex]\frac{3}{4}, \frac{1}{7}, and \frac{5}{6}[/tex]

The denominators are 4, 7 and 6.

LCM of 4,7 and 6 is 84

Then, we will write the fractions in a form whereby they all have the same denominators.

[tex]\frac{3}{4}, \frac{1}{7}, and \frac{5}{6}[/tex]  can be written as

[tex]\frac{63}{84}, \frac{12}{84}, and \frac{70}{84}[/tex]

The resulting order of the numerators gives the order of the fractions.

Now, we will arrange [tex]\frac{63}{84}, \frac{12}{84}, and \frac{70}{84}[/tex] in ascending order. This becomes

[tex]\frac{12}{84}, \frac{63}{84},and \frac{70}{84}[/tex].

∴ The ascending order of the fractions is [tex]\frac{1}{7}, \frac{3}{4},and \frac{5}{6}[/tex].

That is, One-seventh, Three-fourths, and Five-sixths.

Hence, we can write that

One-seventh < Three-fourths < Five-sixths.

This is the inequality which correctly compares Three-fourths, One-seventh, and Five-sixths

The record low temperature in Hawaii is -0.15 times the record low temperature in Alaska. The record low temperature in Hawaii is 12°F. What is the record low temperature in Alaska?

Answers

Answer:the record low temperature in Alaska = -80°F

Step-by-step explanation:

Step 1

Let the temperature in Alaska be = x

such that  the temperature in Hawaii be -0.15 times temperature in Alaska = -0.15 x.

Step 2

IF the   record low temperature in Hawaii is 12°F.

Alaska = ??

We know that

Hawaii= -0.15 x temperature Alaska ( 0.15 x)

12°F=-0.15 x temperature Alaska(x)

Temperature of Alaska, x =  12°F/-0.15

= -80°F

Which statement is true about this quadratic equation? y=-2x^2+9x-12 A. There are two real solutions. B. There is one complex solution. C. There are two complex solutions. D. There is one real solution.

Answers

A quadratic equation is an equation that can be placed in the form a·x² + b·x + c = 0

The option that gives the true statement about the quadratic equation is option C.

C. There are two complex solutions

Reason:

The given quadratic equation can be presented as follows;

y = -2·x² + 9·x - 12

The factored form of the quadratic equation is presented as follows;

The radical of the given quadratic equation is therefore;

[tex]\sqrt{9^2 - 4 \times (-2) \times (-12)} = \sqrt{81 - 96} = \sqrt{-15}[/tex], which gives the following solutions;

[tex]x = \dfrac{(-9\pm\sqrt{-15} )}{2 \times (-2)} = \dfrac{-9 \pm \sqrt{-15} }{-4}[/tex]

[tex]x = \dfrac{-9 +\sqrt{-15} }{-4} \ or \ x = \dfrac{-9 -\sqrt{-15} }{-4}[/tex]

Therefore there are two complex solutions;

First we need to express y in this inequality:

-2y > -4x + 20

-y > -2x + 10

y < 2x - 10

The line isn't solid because the "less" sign doesn't include equal in it.

Because the sign is "less than" the shaded part is Below the line.

I think of a number q, multiply it by 2 and add 5. I get the same answer as when I minus 2 from q. Find the value of q

Answers

Given:

A number is q, multiply it by 2 and add 5.

You get the same answer as when you minus 2 from q.

To find:

The value of q.

Solution:

The algebraic representation of the statement "a number is q, multiply it by 2 and add 5" is

Multiply q by 2 = 2q

Multiply q by 2 and then add 5 : 2q + 5

So, the first result is 2q+5.

When you minus 2 from q = q-2

So, the second result is q-2.

According to the question, both results are equal. Equate both results to get the value of q.

[tex]2q+5=q-2[/tex]

Isolate variable terms.

[tex]2q-q=-5-2[/tex]

[tex]q=-7[/tex]

Therefore, the value of q is -7.

I assume you're asked to solve

Factor the left side:

(4 cos(x) - 3) (cos(x) - 1) = 0

Then either

4 cos(x) - 3 = 0   or   cos(x) - 1 = 0

cos(x) = 3/4   or   cos(x) = 1

From the first case, we get

x = cos⁻¹(3/4) + 2  or   x = -cos⁻¹(3/4) + 2
