Answer:
60 degrees
Step-by-step explanation:
Since all three sides are the same length, all three angles must be the same size. This means the triangle is an equilateral triangle
The angles are 60 degrees
Answer:
x = 0, 4, -2
Step-by-step explanation:
f (x) = 3x (x – 4) (x + 2)
0= 3x (x – 4) (x + 2)
3x = 0, x-4 =0 , x+2 = 0
x = 0, 4, -2
2.)
0 = 6x + 3y +9
-3y = 6x + 3y - 3y +9

By isolating y we now have the equation in slope intercept form:

Where m = slope and b = y- intercept. Therefore, the slope is -2 and the y - intercept is -3.
4.)
Similarly, #4 is already in slope intercept form so we can solve it by inspection. So for #4 the slope is -1 and the y - intercept is 2.
Answer:
The standard form is 
Step-by-step explanation:
The standard form of a linear equation can be written as

The given equation is

This equation is in the slope-intercept form.
To rewrite this in standard form, we must multiply through by the least common multiple which is 4.

We now add
to both sides of the equation to obtain,

This simplifies to

Hence the standard form is

The correct answer is A
Answer:
x = -6, y = -2
Step-by-step explanation:
2x-7y = 2
3x + y = -20
We need to cancel out either x or y to solve the equation. I'll cancel out x first
3(2x-7y = 2)
-2(3x+y=-20)
___________
6x-21y = 6
-6x -2y = 40
____________
-23y = 46
y = -2
Plug the value for y in one of the 2 equations to solve for x
2x -7(-2) = 2
2x+14=2
2x = -12
x=-6
