Answer:
7x+14=0, 7x=-14, x= -2
Step-by-step explanation:
add like terms, then get x on one side, number on the other, then divide both sides by 7
Answer:
x = 48
Step-by-step explanation:
It is a 90 degree angle. So first you would subtract 42 from 90 degrees. Then you'd get your answer! Hope this helped
Answer: The axis of symmetry is x=1.
Explanation:
The given function is,

The degree of the equation is 2. SInce it is a quadratic function therefore the graph of the function is a parabola.
The axis of symmetry of a parabolic function
is a vertical line,

Since the value of a is 5m b is -10 and c is 7, So the axis of symmetry is,



Therefore, the axis of symmetry is x=1.
Answer:
B= 13
Step-by-step explanation:
10x-5= 180-(4x+3)
10x-5=180-4x-3
10x-5+3=180-4x
14x-2=180
14x= 180+2
14x= 182
x=182/14
x=13
