Hello!

Let's solve this equation for y first.

-10x+y=4

Add 10x to both side.

y=10x+4

Now, let's plug in our x-values to find y.

x: -2, -1, 0, 1, 2

y:-16,-6, 4,14,24

I hope this helps!

x = -2 then y = -16

x = -1 then y = -6

x = 0 then y = 4

x = 1 then y = 14

x = 2 then y = 24

0 is the constant of 4, this functions is a pattern of when ever x increases by 1, you add 10 from y starting from 4, example:

x = 5 then y = 5 * 10 + 4 which is y = 54

y = 54 while x = 5 also satisfies the equation.

Same goes for when ever x decreases by 1, example:

x = -5 then y = -5 * 10 + 4 which is y = -46

y = -46 while x = -5 also satisfies the equation.

This question was the pattern illustrated above.

This is derived from when you take -10x+y=4 and solve for y

Simply add 10x to both sides, and you have already isolated the y variable in the equation y = 10x + 4

You can plug the values in for x and solve for y and recognize the same pattern above.

Joe is making a ramp.Find the length of the ramp if the height is 7meters and the base is 24 meters
Musya8 [376]

Answer:

the length of the ramp is 25 meters

Step-by-step explanation:

Joe is making a ramp. Ramp forms a right angle triangle with the base

So we use Pythagorean theorem to find the length of the ramp

AC^2(hypotenuse) = AB^2 + BC^2

Length of ramp is the hypotenuse = \sqrt{height^2 + base^2}

=\sqrt{7^2 +24^2}

= \sqrt{49 + 576^2}

= \sqrt{625}

= 25

so the length of the ramp is 25 meters

Answer:

A. 60°

Step-by-step explanation:

There's a very straight-forward explanation for this, thank god! XD

For this type of problem, there's a rule to follow for the outside angle. X and 120 should equal 180, so all you need to do is fill that gap.

180-120 = 60

60 is your answer because it completes the whole angle.
