Answer:
(6,7,8)
Step-by-step explanation:
solving the inequality will give x>5
Because vertical angles are congruent, angle 78 is congruent to angle x: x=78.
In order to solve the equation we first need to put the condition:
6x+7>=0
x>= -7/6
We square the equation:
x^2=6x+7
x^2-6x-7=0
x^2+x-7x-7=0
x(x+1)-7(x+1)=0
(x-7)(x+1)=0
x1=7
x2=1
Both solutions meet the condition.
Answer:
Y = 1/4x + 1/2
Step-by-step explanation:
The inverse is found by reflecting the graph across the y=x line. In the equation, this result by switching x and y then solving for y.
Y =4x-2
X=4y-2
X+2=4y
(X+2)/4= y
1/4x +1/2 =y
