Arionna needed to graph triangle PQR reflected across the y-axis. Her work is shown below.

Arionna’s Work:
Blue right-arrow red. P (3,7) right arrow P prime (3, negative 7). Q (0, 4) right-arrow Q prime (0, 4). R (5, 8) right-arrow R prime (negative 5, 8).

Answer: -3x-7

Step-by-step explanation:

Answer:

x=99

Step-by-step explanation:

Move all terms not containing  x  to the right side of the equation.

Check the attachment(s) for the graphs pertaining to the question

No. 1) Check graph [first attachment]

No. 2) y = (x - 2)^2 - 3, y = 1

           (x - 2)^2 - 3 = 1,

           (x - 2)^2 = 4

            x - 2 = √4, x - 2 = - √4

            x = 4, x = 0

Substitute back to determine the respectively y-value:

y = (4 - 2)^2 - 3 = (2)^2 - 3 = 4 - 3 = 1

Check: y = (0 - 2)^2 - 3 = (-2)^2 - 3 = 4 - 3 = 1

So the points of intersection are (4, 1) and (0, 1). According to the graph, that is correct.

Answer:

y is greater than or equal to -2x-5

Step-by-step explanation:

First find the slope which is -2x and then find the y-intercept which is -5 and then you can just test out if its greater than or equal to, or less than or equal to. To do this you just fill in the point 0,0 and if you do that you should get 0 is  greater than (you can ignore the "or equal to") -5 and is that true? Yes it is! so then the side of the line that the point 0,0 is on should be shaded and since it is your answer is right!

Hope this helped!

Answer:

115

Step-by-step explanation:

To find the missing angle all you have to do is add the 2 nonadjacent interior angles which are 75 and 40 to get the exterior angle which is 115.

Answer: 10

Step-by-step explanation: (5/6) times 12

Answer:

10

Step-by-step explanation:

[tex]\frac{5}{6}[/tex] × [tex]\frac{12}{1}[/tex]

Multiply 12 times 5 to get 60. Then, multiply 6 times 1 to get 6.

Lastly, divide 60 by 6, which equals 10.

Answer: (3.65, 3.74)

Step-by-step explanation:

Now, when we round a number to a given decimal place, we need to look at the decimal to the left of the decimal place where we are rounding.

if it is 5 or more, we round up

if it is smaller than 5, we round down.

Then for example, if we want to round:

4.534

to the first decimal place, we need to look at the second decimal place.

we can see that it is a 2.

Then we round down, and get:

4.5

Now we know that, when rounding to the first decimal place, we have:

x = 3.7

Then the maximum value that x could have is:

x = 3.74 (because here we round down to 3.7)

and the minimum value that x could have is:

x = 3.65 (because here we round up to 3.7)

Then the error interval for x is:

(3.65, 3.74)

solve : 2(5x + 3) = 25

▶️2(5x + 3) = 25

▶️ 2 × 8x = 25

▶️ 16x = 25

▶️ x = 25/16

▶️ x = 1.5625

1.5625

Step-by-step explanation:

Step 1:

2(5x+3)=25

(2)(5x) + (2)(3)=25 (distribute)

10x+6=25

Step 2:

10x+6 - 6 = 25 - 6

10x =19

Answer :

X=19 of 10

Answer:

each bottle of juice costs $2.34

Step-by-step explanation:

2.74+10x=26.14

10x=26.14-2.74

10x=23.40

x=23.40/10

x=2.34

Answer:

8

Step-by-step explanation:

So first do 104+76+104=284

Now form the equation 10x-4+284=360

It is 360 because this is a quadrilateral.

Now combine like terms.

10x+280=360

10x=80

x=8

Check 80-4=76

The other angle is 76 so you know your answer is correct

Answer:

19 683

Step-by-step explanation:

To be able to do this, just remember that for example 3 square which is the number "3^" is 3 x 3 and it is the same for others, like 3^^ is 3 x 3 x 3 x 3.

A calculator is helpful for this question, but still doable without calculator.

Answer:

The ratio of the number of dogs to the total number of dogs and cats in the veterinarian's office is 9:16.

Step-by-step explanation:

Ratio:

The ratio of a to b is given by:

[tex]a:b = \frac{a}{b}[/tex]

The ratio of dogs to cats in a veterinarian's office is 9:7.

This means that for each 9 dogs, there are 7 cars.

What is the ratio of the number of dogs to the total number of dogs and cats in the veterinarian's office?

9 dogs

9 + 7 = 16 dogs and cats. So

The ratio of the number of dogs to the total number of dogs and cats in the veterinarian's office is 9:16.

Answer:

Angle T = 43°

Step-by-step explanation:

118+118+81 = 317

360-317 = 43

Step-by-step explanation:

8x+17 = 30 + 5x +20

3x = 30 + 20 -17

3x = 30 + 3

3x = 33

x = 33/3

x = 11

measures = angle Q= 5x +20 = 5(11)+ 20 = 55+20 = 75

hope this will be helpful to you.
