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: (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)

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:

0.2 = 20% probability that a student takes Spanish and engineering

Step-by-step explanation:

We solve this question treating the probabilities as Venn sets.

I am going to say that:

Event A: Student takes Spanish

Event B: Student takes Engineering.

35% of students take spainsh or engineering.

This means that [tex]P(A \cup B) = 0.35[/tex]

30% of students take Spanish.

This means that [tex]P(A) = 0.3[/tex]

25% of students take engineering.

This means that [tex]P(B) = 0.25[/tex]

What is the probability that a student takes Spanish and engineering?

This is [tex]P(A \cap B)[/tex].

These probabilities are related by the following formula:

[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]

So

[tex]P(A \cap B) = P(A) + P(B) - P(A \cup B)[/tex]

Replacing the values

[tex]P(A \cap B) = 0.3 + 0.25 - 0.35 = 0.2[/tex]

0.2 = 20% probability that a student takes Spanish and engineering

Answer:

Answer:

(3 × 10⁶)³ is equal to 2.7 × 10¹⁹

Step-by-step explanation:

You can solve this by raising both terms in the brackets to the power of three:

(3 × 10⁶)³

= 3³ × 10⁶ˣ³

= 27 × 10¹⁸

= 2.7 × 10¹⁹

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.

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

X=19 of 10

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: 2x + 20

Step-by-step explanation:

2x + 20

2 (-3) + 20

-6 + 20 = 14

The expression (2 * X) + 20 will have a value of 14 when X = -3.To create an expression that evaluates to 14 when X = -3, we can use a combination of arithmetic operations.

Let's start with the variable X = -3.

One possible expression is:

(2 * X) + 20

Substituting X = -3:

(2 * (-3)) + 20 = -6 + 20 = 14

Therefore, the expression (2 * X) + 20 will have a value of 14 when X = -3.
