Answer:
The first one is for y = -x + 3
The second one if for y = 2x - 6
Hope this helps, sorry if isn't the exact answer you were looking for!
So when x = -1, you just substitute the variable x to -1.
"4x" means 4 times x, so when x is replaced to -1, that would be 4 times -1.
f(-1) = 4(-1) = -4
So the value of function at x = -1 would be -4.
Hope this helps.
The vertical angles theorem states that vertical angles are congruent to each other. Since angles E and F are vertical angles, this means you can make them equal to each other in an equation.
m∠E = m∠F
17x + 1 = 20x - 14
Subtract 20x from both sides.
-3x + 1 = -14
Subtract 1 from both sides.
-3x = -15
Divide both sides by -3.
x = 5
Substitute 5 for x in m∠F (20x - 14).
20(5) - 14 = 86
m∠F = 86°
here it is in bio they wont let me type it
