Which ordered pair (x,y) satisfies the system of equations shown above?

Answer:

60

Step-by-step explanation:

100% = 80,

75% = 80/100*75= 60

Step-by-step explanation:

100% = 80

/ 100

1% = 0.8

x75

75% = 60

? = 60

Answer:

4x - 1

Step-by-step explanation:

Given the area

16x² - 8x + 1

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 16 × 1 = 16 and sum = - 8

The factors are - 4 and - 4

Use these factors to split the x- term

16x² - 4x - 4x + 1 ( factor the first/second and third/fourth terms )

= 4x(4x - 1) - 1(4x - 1) ← factor out (4x - 1) from each term

= (4x - 1)(4x - 1)

= (4x - 1)²

The area of a square = s² ( where s is the length of the side )

s² = (4x - 1)², thus

s = 4x - 1 ← length of side of square

Answer:

We have the equation A*C = A

Now, as both sides of the equality are the same thing, we can do the same operation to both sides and the equality will remain true.

We can divide both sides by A and get:

(A*C)/A = A/A

C = 1

So here we finded the value of A.

If A and C are matrices, then C is the identity matrix.

Answer:

u = 5

Step-by-step explanation:

→Distribute the 3 to (-3u - 5):

4u = 16u - 9u - 15

→Add like terms:

4u = 7u - 15

→Subtract 4u from both sides:

0 = 3u - 15

→Add 15 to both sides:

15 = 3u

→Divide both sides by 3:

5 = u

Answer:

[tex] \boxed{u = 5} [/tex]

Step-by-step explanation:

[tex] = > 4u = 16u + 3( - 3u - 5) \\ \\ = > 4u = 16u + (3 \times ( - 3u)) - (3 \times 5) \\ \\ = > 4u = 16u - 9u - 15 \\ \\ = > 4u = 7u - 15 \\ \\ = > 4u - 7u = - 15 \\ \\ = > \cancel{- }3u = \cancel{- }15 \\ \\ = > 3u = 15 \\ \\ = > u = \frac{15}{3} \\ \\ = > u = 5[/tex]

Answer:

60

Step-by-step explanation:

-5(-2-10)

according to pemdas...solve parenthesis first

-5(-12)

= 60

Answer:

60

Step-by-step explanation:

x ( y - x y )

where x= -5 and y= -2

----------

-5(-2-(-5)(-2))=-5(-2-10)= -5(-12)= 60

Answer:

a) 12 1/2 cm

b) 5 1/4 cm

Step-by-step explanation:

The piece of string is 24 cm long.

It is cut in three pieces.

Let the length of the first piece be x.

The second piece is twice as long as the first. This means that the length of the second piece is 2x.

The third is 1 cm shorter than the first. This means that the length of the third piece is x - 1

Therefore:

x + 2x + x - 1 = 24

4x - 1 = 24

4x = 25

x = 25 / 4 = 6 1/4cm

Therefore, the length of the second piece will be:

2 * 25/4 = 25/2 = 12 1/2 cm

The length of the third piece will be:

6 1/4 - 1 = 5 1/4 cm

Answer:

B.

Step-by-step explanation:

It is very possible.

Make the value of apple x and the value of orange y.

5x + 4y = 10

5x + 5y = 11

-y = -1

y = 1

x = 1.2

Now just match them up.

Yes; They should charge $1.20 for and apple and $1.00 for an orange.

Answer:

y=4

Step-by-step explanation:

Line E ( that is a cursive l) is a horizontal line

Horizontal lines are of the form y=

The y coordinate for the orange line is 4

y=4

Answer:

y = 4

Step-by-step explanation:

horizontal lines are written as y =

y coordinate is 4

So the eqn is y = 4

Step-by-step explanation:

Answer:

y = - 1/3 x + 1

Step-by-step explanation:

(6, -1) and (-3, 2)

Slope = (y2  - y1)/(x2 - x1) = (2 - (-1))/(-3-6) = 3/(-9) = - (1/3)

y-int form is y = ma +b

y = - 1/3 x +b

(-3, 2)

2 = (- 1/3)*(- 3)+ b

2 = 1 + b

b = 1

y = - 1/3 x + 1

Answer:

Point B is [tex](-1,2)[/tex]

Step-by-step explanation:

Given: A triangle ABC was rotated 90 degrees counterclockwise

To find: coordinates of the point B

Solution:

A triangle is three - dimensional figure that has three sides, three vertices and three angles.

Counterclockwise refers to the direction opposite to the direction of movement of hands of the clock.

As triangle ABC was rotated 90 degrees counterclockwise about the origin, point B is [tex](-1,2)[/tex]

Answer:X+9=11

9-9|11-9

X=2

Step-by-step explanation:When the beginning number is unknown we use “x” to be a place holder. If she got 9 more books we would add 9 to the equation. Finally if 11 is the total, the end of the equation would equal 11.

Answer:

4.50 = ?

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

sin theta = opposite / hypotenuse

sin 40 = ? / 7

Multiply each side by 7

7 sin 40 = ?

4.499513268 = ?

To the nearest hundredth

4.50 = ?

Answer:

The first set (A)

Step-by-step explanation:

The five inputs are {-12, -3, 0, 3, 12}.  The first set (A) includes all five of these inputs and a single output for each of them:  {(-12, -18), (-3, -3), (0, 2), (3, 7), (12, 22).

Using the given function,  the correct set of ordered pairs for the following domain values is A; {(-12, -18), (-3, -3), (0, 2), (3, 7), (12, 22).

The domain of a function is defined as the set of all the possible input values that are valid for the given function. The range of a function is defined as the set of all the possible output values that are valid for the given function.

The five inputs are given as;

{-12, -3, 0, 3, 12}

WE can see that first set (A) includes all five of these inputs and a single output for each of them;

{(-12, -18), (-3, -3), (0, 2), (3, 7), (12, 22).

Therefore, Using the given function,  the correct set of ordered pairs for the following domain values is A; {(-12, -18), (-3, -3), (0, 2), (3, 7), (12, 22).

Multiply the Price Percentage by the Original Price

Multiply the original price and the percentage that represents the sale price; the result is the sale price of the blazer in dollars: $90 × 0.7 = $63. So if the blazer is on sale for 30 percent off, you'll pay the remaining 70 percent of the price, which is $63.
