Given table:

The data above shows that:

The line has equation:

The graph is attached and the points included

Answer:

[tex]\Large \boxed{2A+2}[/tex]

Step-by-step explanation:

Two points are (0, 2) and (2, 6)

Calculate slope m

[tex]\displaystyle m=\frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]\displaystyle m=\frac{6-2}{2-0}=2[/tex]

Use slope-intercept form

[tex]y=mx+b[/tex]

[tex]y=2x+b[/tex]

b  is the y-intercept, y-intercept is (0, 2)

[tex]y=2x+2[/tex]

Answer:

10 Miles

Step-by-step explanation: The ratio for the problem is 1:6, multiply the 6 by 10 to get an hour and in a ratio you must multiply the number on booth sides by the same thing, the 1=miles and the 6=minutes

Answer:

The slope of the line is m = 3

Step-by-step explanation:

You can easily verify that if x decreases by 2 (e. g., from -4 to -2), y increases by 6.  Thus, the slope is m = rise/run = 6/2 = 3

Answer:

It is a segment connecting the midpoints of two sides of a triangle. It is always parallel to the third side, and the length of the midsegment is half the length of the third side. As shown in the triangle given below. Therefore the value of x is 15 .

Step-by-step explanation:

Using the Triangle Midsegment Theorem, it is found that x = 14.

The Triangle Midsegmenet Theorem states that the length of the midsegment is half the length of the base.

In this problem:

Thus, applying the theorem:

[tex]\frac{x}{2} = 7[/tex]

[tex]x = 14[/tex]

The value is x = 14.

Answer:

(a) La altura del monumento en metros es de aproximadamente 8.544 m

(b) La distancia recorrida por Mariana y su familia desde Quito a Mompiche en metros es 426,200 m

Step-by-step explanation:

(a) La distancia del que toman la foto desde la base = 300 cm

La distancia diagonal de su rostro al fotógrafo = 800 cm.

Según el teorema de Pitágoras, la altura, h = √ ((800 cm) ² + (300 cm) ²) ≈ 854.400374532 cm

La altura del monumento, h ≈ 854,4 cm

La altura del monumento en metros, h ≈ 8.544 m

(b) La distancia total recorrida por Mariana y su familia desde Quito a Mompiche, d = (338.72 + 34.36 + 53.12) km = 426.2 km

La distancia recorrida en metros, d = 426,2 km × 1.000 m / km = 426.200 m

La distancia recorrida por Mariana y su familia desde Quito a Mompiche en metros, d = 426,200 m

C = (5/9)(F-32)

distribute the 5/9:

C = (5/9)F - 160/9

Answer:

160:140

Step-by-step explanation:

8+7 = 15

60000/15 = 4000

4000/200=20

therfore the dimensions are 20 times the amount

8x 20 = 160

7x 20 = 140

Answer:

7x - 12

Step-by-step explanation:

'12 less' means thats u have to subtract 12 from the next number

'7 times a number' means 7 multiplied by a variable like x, y, or z

you put those two together and get 7x - 12

Answer: 7x-12

Step-by-step explanation:

“12 less than” would simply imply “subtract 12 from” the sum of 7 times a number. Let “x” represent the unknown number and multiply it by 7.

Answer:

  (x, y) = (2, 3)

Step-by-step explanation:

"Removal method" is a new one for me. We presume it is another name for the "elimination" or "addition" method.

Multiply the second equation by 5 and add the first.

  (6x -5y) +5(-4x +y) = (-3) +5(-5)

  -14x = -28 . . . . . simplify

  x = 2 . . . . . . . . . divide by -14

  -4(2) +y = -5 . . . substitute for x in the second equation

  y = 3 . . . . . . . . . add 8

The solution is (x, y) = (2, 3).

__

Check

We found y using the second equation, so we know the values of x and y work in that one. We only need to check the values in the first equation.

  6(2) -5(3) = -3

  12 -15 = -3 . . . . . true; answer checks OK

Answer:

i dont know sorry

Step-by-step explanation:

Answer:

-2

Step-by-step explanation:

The functions of f(x) and g(x) are given

For f(x)+g(x)=0 , functions f and g should be in opposite sign

We can observe that at x=−2 , f(x)=2 and g(x)=−2

Therefore f(−2)+g(−2)=0

So the correct option is D (-2)
