Answer:

R is at the ordered pair (4, -2)

Step-by-step explanation:

Answer:

∠ ABC = 108°

Step-by-step explanation:

The 2 given angles are vertically opposite and are congruent , that is

4x + 8 = 3x + 33 ( subtract 3x from both sides )

x + 8 = 33 ( subtract 8 from both sides )

x = 25

Then

∠ ABC = 3x + 33 = 3(25) + 33 = 75 + 33 = 108°

[tex](x_1,y_1) = (-3,4),~~ (x_2,y_2) = (2,-1)\\\\\text{Slope,}~ m = \dfrac{y_2 - y_1}{x_2 - x_1} =\dfrac{-1-4}{2+3} = \dfrac{-5}5 = -1[/tex]

Step-by-step explanation:

A number of books and their cost where the subscription with the annual fee costs less. hope it helps and take care ✌

Point S represents the number of books and their cost using the subscription that charges per book

Option A is the correct answer.

An equation contains one or more terms with variables connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 8 is an equation.

We have,

Based on the given graph, point S represents the number of books and their cost using the subscription that charges per book (Option A).

This is because point S is located below line B, which represents the total cost of the subscription with a variable cost per book, and above line A, which represents the total cost of the subscription with a fixed annual fee.

Therefore,

Point S represents a combination of a certain number of books borrowed and the corresponding total cost of the subscription using the variable cost per book option.

Explanation:

The term "collinear" means "points that fall on the same straight line". Any two points are always guaranteed to be collinear; however the same can't be said for any 3 random points.

In this case, points P, Q and S are all on the vertical y axis which is why they are collinear.

Answer:

$47.4

Step-by-step explanation:

Answer:

Step-by-step explanation:

The earning will increase for 6 hours. So, we have to multiply 7.90 by 6

Earnings after 6 hours =  6 * 7.90 = £  47.40

Answer:

6$

Step-by-step explanation:

2+4=6

20%+40%=60%

The new price after the increase is $2.8 .

Percentage increase is the difference between the final value and the initial value, expressed in the form of a percentage. In other words, it is the difference between the final value and the initial value which is divided by the initial value and then multiplied by 100.

According to the question

The price of chocolate bar = $2

The price of a particular chocolate bar is increased by 40%,

i.e

The percent increase in the price of chocolate bar = 40%

Now,

increase prize :

= [tex]2*\frac{40}{100}[/tex]

= $0.8  

The new price after the increase

= $2.8

Hence, the new price after the increase is $2.8 .

Answer:

As an improper fraction, the answer is 14/5, and as a mixed fraction, the answer is 2 4/5.

Step-by-step explanation:

Answer:

Step-by-step explanation:

(a + b)² =a² + 2ab + b²

(a -b)² = a² - 2ab + b²

1) y = (x -1)²

 y= x² -  2*x*1 + 1

y = x² - 2x + 1    

Ans: C

2)y = (x +4)² + 5

y = x² +2*x*4 + 4² + 5

  = x² + 8x + 16 + 5

y = x² + 8x + 21

C

3) y = -(x + 9)²- 10

y = - [x² + 18x + 81] - 10

= -x² - 18x - 81 - 10

y =-x² - 18x - 91

B

4) y = 3(x + 2)² - 18

y =3 [x² + 4x + 4] - 18

y =  3x² + 12x  + 12 - 18

y =3x²  + 12x - 6

A

5) y = -2(x + 1)² - 16

       = -2[x² + 2x + 1] -16

       = -2x² - 4x - 2 - 16

     y = -2x² - 4x -  18

A

6) y = 5(x + 5)²

        =5[x²+ 10x + 25]

y = 5x² +50x + 125

A

7)y = (1/2)(x + 8)² - 8

  y = (1/2) (x² + 16x + 64) - 8

[tex]y = \dfrac{1}{2}*x^{2}+ \dfrac{1}{2}*16x + \dfrac{1}{2}*64 -8\\\\\\y =\dfrac{1}{2}x^{2}+8x +32 - 8\\\\\\y=\dfrac{1}{2}x^{2} +8x + 24[/tex]

A

8) y = (x + 3/2)² + 3/4

[tex]y = x^{2} +2*x*\dfrac{3}{2}+\dfrac{9}{4}+\dfrac{3}{4}\\\\y=x^{2}+3x+\dfrac{12}{4}\\\\\\y=x^{2}+3x + 3[/tex]

C

9) y = 2[x² + 16x + 64] - 5x

y = 2x² + 32x + 64 - 5x

y =2x² + 27x + 6

Answer:

28.3

Step-by-step explanation:

if a side is 90 degrees, this makes the two other angles 45 degrees.

if the base side is 40, this makes the two other sides 28.284.

rounding 28.284 to the nearest tenth, we get 28.3

+400, +50, 50 - 400, 50 + (-400) = -350

+400, -120, -120 - 400, -120 + (-400) = -520

+400, -75 3/4, -75 3/4 - 400, -75 3/4 + (-400) = -475 3.4

-200, +610, 610 - (-200), 610 + 200 = 810

-200, -50, -50 - (-200), -50 + 200 = 150

-200, -500, -500 - (-200), -500 + 200 = -300

-200, 0, 0 + 200, 0 - (-200) = 200

-200, 120 1/2, 120 1/2 - (-200), 120 1/2 + 200 = 320 1/2

I think this might be the answer.
