Step-by-step explanation:
you know by using the x and y coordinates of the point in the equations and see, if both equations are still true.
if yes, it was a solution, and if just only one is false, then it was not a solution.
(3, -2) in
y + 4x = 10
5x - y = 13
so,
-2 + 4×3 = 10
-2 + 12 = 10
10 = 10 true
5×3 - (-2) = 13
15 + 2 = 13
17 = 13 false
so, it was NOT a solution.
Answer:
The slope is undefined and there is no y- intercept
Step-by-step explanation:
The line is equivelent to x=5
This is a vertical line so the slope is undefined and there is no y- intercept
Answer:
1=51°
2=18°
3=123°
4=39°
Step-by-step explanation:
Answer:
sqrt(104) =x
Step-by-step explanation:
We can use the Pythagorean theorem since this is the right triangle.
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse.
2^2 + 10^2 = x^2
4+100 = x^2
104 = x^2
Take the square root of each side
sqrt(104) = sqrt(x^2)
sqrt(104) =x
