5sqrt(x+7)=-10
Dividing both sides by 5:
5sqrt(x+7)/5=-10/5
sqrt(x+7)=-2
Squaring both sides of the equation:
[sqrt(x+7)]^2=(-2)^2
x+7=4
x+7-7=4-7
x=-3
Replacing in the original equation:
5sqrt(x+7)=-10
5sqrt(-3+7)=-10
5sqrt(4)=-10
5(2)=-10
10=-10 It's not equal, then x=-3 is an extraneous solution
Answer:
Measures of all angles are 57°, 57°, 123°, 123°
Step-by-step explanation:
Given:
Sum of two angles = 114°
Find:
Measures of all angles
Computation:
Sum of all 4 angles = 360°
Sum of remain 2 angles = 360° - 114°
Sum of remain 2 angles = 246°
So, first two angles = 114° / 2 = 57°
Second two angles = 246° / 2 = 123°
So, measures of all angles are 57°, 57°, 123°, 123°
I think it is A) Yes, because every x-value corresponds to exactly one y-value
