Please Help Me with this Question. I do not understand it.

Answer:

Yes. the relation is a function

Step-by-step explanation:

Here, we want to check if the relation is a function

if a relation is a function, then every x-values (input values) will have one y-value

No two output values (y values) will have a single x value

Looking at the pairs;

It is a function

Although two x values have same y value; 2 and 3 to 8; no two y values have same x value

Hence, the ordered pairs is a function

Answer:

x=1. (1, 2)

x=2. (2, 5)

Step-by-step explanation:

[tex]\mathrm{Apply\:complex\:arithmetic\:rule}:\quad \left(a+bi\right)\left(c+di\right)=\left(ac-bd\right)+\left(ad+bc\right)i[/tex]

[tex]a=14,\:b=-2,\:c=7,\:d=12[/tex]

[tex]=\left(14\cdot \:7-\left(-2\right)\cdot \:12\right)+\left(14\cdot \:12+\left(-2\right)\cdot \:7\right)i[/tex]

Answer:

y=-3/2x+13

Step-by-step explanation:

Convert to slope-intercept form (y=mx+b):

-3x+2y=10

-3x-10+2y=0

-3x-10=-2y

-3/2x-5=y

y=-3/2x-5

Parallel lines have the same slope, so the slope of the equation will be m₁=m₂ where -3/2=-3/2

Solving for b, the y-intercept, we get:

y=-3/2x+b (Equation so far)

7=-3/2(4)+b [Plugging in (4,7)]

7=-12/2+b

7=-6+b

13=b

Therefore, the equation of the line that is parallel to the line -3x+2y=10 and goes through the point (4,7) is y=-3/2x+13

Answer: 350km

Step-by-step explanation:

Since we are informed that the scale of map is 1cm : 70km. Therefore, the actual distance between towns that are 5cm apart on the map will be:

= 5 × 70km

= 350km

Therefore, the answer is 350km

Step-by-step explanation:

Answer:

13.7477270849 to 19.7230829233.

Step-by-step explanation:

1. Using the pythagorean theorem, a²+b²=c², we try different combinations of given lengths 10 and 17.

2. If 10 and 17 are legs and 10²+17²=√389 = 19.7230829233, then c=19.7230829233.

3. If 10 is a leg and 17 is a hypotenuse,

10²+b²=17²

100+b²=289

b²=189

b=13.7477270849

4. The case of 17 is a leg and 10 is a hypotenuse is not possible because the hypotenuse is the longest side.

5. The range of the length of the 3rd side is 13.7477270849 to 19.7230829233.

Answer:

x = 2

Step-by-step explanation:

-8(x-6) = 32 (distribute)

-8x+48 = 32 (subtract 48 from both sides)

-8x = -16 (divide)

x = 2

Answer:

x = 2

Step-by-step explanation:

Divide both sides :

−8(x−6)=32

Divide both sides of the eqaution by -8 :

x - 6 = -4

Move the constant to the right :

x - 6 = -4

Move the constant to the right - hand side and change its sign :

x = -4 + 6

Calculate :

x = -4 + 6

Calculate the sum :

x = 2

Therefore, the answer is x = 2

Answer:

12

Step-by-step explanation:

A : B

1 : 3

Since we know that B is 3 times of A and A is 4...

1 unit = 4

3 units = 4 x 3 = 12

Answer:

52%

Step-by-step explanation:

Since there are 25 numbers in 1-25, you need to divide 100/25 which is 4.

There are 13 odd numbers in 1-25 so you need to multiply 13x4.

13x4=52

There is a 52% chance she will pick an odd number.

Answer:

32 km/ hr

Step-by-step explanation:

Given that :

Speed of car = 24km/ hr

Time taken =. 80 minutes = 80 / 60 = 1.33333 hours

The distance traveled :

Speed * time

24 km/hr * 1.333333 = 32 km

Speed required to complete 32 km. Journey in 60 minutes = 1 hour

Speed = distance / time

Speed = 32 km / 1 hour

Speed = 32 km/ hr

Answer:

Her solution is correct

(6-2)^2 + (8-3)^2

=(4)^2 + (5)^2

=16 + 25

=41

Answer:

If all of the observed values in a sample are close to the sample mean, the standard deviation will be small (i.e., close to zero), and if the observed values vary widely around the sample mean, the standard deviation will be large. If all of the values in the sample are identical, the sample standard deviation will be zero.

Answer:

60 degrees

Step-by-step explanation:

This is an equilateral triangle. Each angle has the same measure. There are three angles. So: 180 ÷ 3 = 60.

Answer:

60

Step-by-step explanation:

The figure shown is a triangle

To be more specific an equilateral triangle.

We know that this is an equilateral triangle because all of the side lengths are congruent ( indicated by the little mark on each side ) and if each side length is congruent then each angle is congruent.

Because the sum of the angles in a triangle adds up to equal 180 we can simply find the measure of each angle by dividing 180 by 3

180/3=60

so every angle = 60 degrees

Therefore your answer is 60
