Step-by-step explanation:
1/2* 8 (4 + 6) equation
4 (10) simplify
40
Answer:
The solution to this question is 39
Step-by-step explanation:
Given that :
√(3x+7)+2√(x-8)=0.
√(3x+7)=-2√(x-8) (i)
square of the equation (i)
Then
(√(3x+7))^2=(-2√(x-8))^2
we know that √a*√a=(√a)^2=a So,
(3x+7)=4(x-8)
3x+7=4x-32 //multiply by 4
32+7=4x-3x exchange the value.
39=1x
x=39.
Answer: b (-2,3)
Step-by-step explanation:
you substitute the x and y values in (-2,-3) for the x and y in the problem.
That's just too bad. I don't the answer. I'm just doing this to get points. Good luck.
