Answer:
Step-by-step explanation:
We are given:
And we want to solve for <em>x</em>.
First, we can add 49 to both sides:
Now, we can take the square root of both sides. Since we are taking an even root, we will need plus-minus. Hence:
Evaluate:
Subtract 7 from both sides:
So, we have two solutions:
Evaluate:
So, from least to greatest, our solutions are:
Answer:
.

Answer:
x is any real number
Step-by-step explanation:
Think about it. Any number is either less than 2, equal to 2, or greater than 2.
The solution set is <em>all real numbers</em>.
We know that
the equation of the altitude to hk passes through point g and is perpendicular to segment hk
step 1
find the slope segment hk
<span>h (1.-3) k(2,7)
slope m=(y2-y1)/(x2-x1)----> m=(7+3)/(2-1)----> m=10
if two lines are perpendicular
so
m1*m2=-1
the altitude to hk has a slope
m2=-1/10
step 2
with m=-1/10 and point </span><span>g(-3,4) find the equation of the line
y-y1=m*(x-x1)-----> y-4=(-1/10)*(x+3)---> multiply by 10
10y-40=-x-3----> 10y+x=37-----> equation of the altitude
the answer is
</span>10y+x=37
