Is the point (-1,5) a solution to the equation y=2x-4?

No because if you plug in -1 for x and 5 for y 5 doesn’t equal -6. You just plug in the point as x and y and if the equation is true then the point is a solution.

Logan wants to move to a new city. He gathered graphs of temperatures for two different cities. Which statements about the data
Bad White [126]

Answer:

The correct options are;

Therefore, City A is likely to have temperatures that remain fairly constant all year round because it has a compact interquartile range compared to that of City B

City B is likely to have more extreme temperatures with colder days in the winter and hotter days in the summer because the range is greater than that of A

Step-by-step explanation:

Here we have for City A

Maximum - Minimum = 10

Interquartile range =3

City B

Maximum - Minimum = 18.5

Interquartile range =9.5

Therefore, City A is likely to have temperatures that remain fairly constant all year round because it has a compact interquartile range compared to that of City B

City B is likely to have more extreme temperatures with colder days in the winter and hotter days in the summer because the range is greater than that of A.

The sum of 5/2 and 6 times a number equals to 7/2 subtracted from seven times the number find the number
kykrilka [37]

Answer:

1 / 13

Step-by-step explanation:

lets just say the number is 'x'

5/2 + 6x = 7/2 - 7x

6x + 7x = 7/2 - 5/2

13x = 2/2

13x = 1

x = 1/13

proving it

5/2 + 6 × 1/13 = 7/2 - 7 × 1/13

5/2 + 6/13 = 7/2 - 7/13, solving the fraction by finding the L.C.M will result in

77/26 = 77/26

Your house is located at point T. Your grandma's house is located at point V. U is the midpoint of segment TV. How far do you ne
Vladimir [108]

Answer:

70

Step-by-step explanation:

From the question given above, the following data were obtained:

TU = 8x + 11

UV = 12x – 1

Next, we shall determine the value of x.

From the question:

U is the midpoint. This means that TU and UV are equal i.e

TU = UV

With the above idea in mind, we shall determine the value of x as follow:

TU = UV

TU = 8x + 11

UV = 12x – 1

8x + 11 = 12x – 1

Collect like terms

11 + 1 = 12x – 8x

12 = 4x

Divide both side by the coefficient of x i.e 4

x = 12/4

x = 3

Next, we shall determine the length of TU and UV. This can be obtained as follow:

TU = 8x + 11

x = 3

TU = 8(3) + 11

TU = 24 + 11

TU = 35

UV = 12x – 1

x = 3

UV = 12(3) – 1

UV = 36 – 1

UV = 35

Finally we shall determine the length of TV. This can be obtained as follow:

TV = TU + UV

TU = 35

UV = 35

TV = 35 + 35

TV = 70

Therefore, the distance between my house and grandma's house is 70.

NOTE: Assume the distance is measured in kilometer (km)

This means that I will travel 70 km from grandma's house to my house.
