For this case we have the following equation:

$y = 3x + 4$

We must find the value of the variable y when the variable x takes certain values.

For $x = 1:$

$y = 3 (1) +4\\y = 3 + 4\\y = 7$

For $x = 2:$

$y = 3 (2) +4\\y = 6 + 4\\y = 10$

For $x = 3:$

$y = 3 (3) +4\\y = 9 + 4\\y = 13$

Thus, the values of y are 7,10,13 respectively.

Answer:

$y = 7\\y = 10\\y = 13$

Answer:

x=1 y= 7

x=2 y= 10

x=3 y= 13

Step-by-step explanation:

y=3x+4

y=3(1)+4

y=3(2)+4

=-10

y=3(3)+4

=13

A stone is thrown upward from ground level. With what minimum speed should the stone be thrown so as to reach a height of 36 fee

rusak2 [61]

V^2 = u^2 - 2gh; where v is the final speed, u is the initial speed, g = 9.8 m/s = 0.54 ft/min is the accerelation due to gravity, h = height.
At the maximum height, the final speed is 0.
u^2 = 2gh = 2 x 0.54 x 36 = 38.58
u = sqrt(38.58) = 6.21 ft/min

Therefore, the stne should be thrown with 6.21 ft/min

On a coordinate plane, how are the locations of the points (-4 , 8) and (-4 , -8) related?

STALIN [3.7K]

Answer:

A. reflection across the y-axiss

Step-by-step explanation:

Given:

The locations of the two points are (-4 , 8) and (-4 , -8).

To find:

The relation between two points.

From the given points (-4, 8) and (-4 , -8), it is clear that the y-coordinates are same but the sign of x-coordinates are opposite.
