Answer:
Correct option: D
Step-by-step explanation:
In the figure we have a right triangle, that is, one of the angles is a 90° angle. Therefore, we can use the Pythagoras' theorem to find the relation between the sides of the triangle:
Where b and c are cathetus of the triangle (sides adjacent to the 90° angle) and a is the hypotenuse (opposite side to the 90° angle).
So in our case, we have that x is the hypotenuse, and 40 and 42 are cathetus, so we have:
So the correct option is D.
Answer:
See answers below
Step-by-step explanation:
The equation for slope-intercept form is y=mx+b where m is the slope and b is the y-intercept. Solving for y will change the original equation into slope-intercept form:
We can do the same thing for the second equation:
Answer:
Because they will give same answer.
Step-by-step explanation:
12x +24x +18 = 36x +24 -6
36x +18 = 36x +18
Equation of line passing through two points =
Now , we will find first equation of line which passes through (-4,4) and (-2,0) is :
The Second line which passes through (0,-4) and (2,-8) is :
So equation of line passing through (-4,4) , (-2,0) ,(0,-4) and (2,-8) is :(All points are collinear, so there will be unique line passing through these four points.)
2 x + y + 4=0
