G/3 - 7 = 15 --> g/3-7+7 = 15+7 --> g/3 = 22 --> g/3*3 = 22*3 --> g = 66
Answer:
15 inches
Step-by-step explanation:
x+5+2x-3+7x+1=103
10x+3=103
10x=100
x=10
Answer:
x =
Step-by-step explanation:
Using the rule of exponents
=
Note that 8 = 2³ and 2 = , then
= , that is
=
Since the bases on both sides are equal, equate the exponents
3x = 1 ( divide both sides by 3 )
x =
Answer:
It is correct
Step-by-step explanation:
Has two solutions x = a and x = -a because both numbers are at the distance a from 0. You begin by making it into two separate equations and then solving them separately. An absolute value equation has no solution if the absolute value expression equals a negative number since an absolute value can never be negative.
I'm assuming you have. The first thing we do is find the slope of the tangent line by finding the derivative of the equation at the point (5,6).
expanding the equation
x^2 - 4x + 4 + y^2 - 4y + 4 = 25
Finding the derivative
2x - 4 + 2y y' - 4y' = 0
y'( 2y - 4) = 4 - 2x
y' = (4 - 2x) / (2y - 4)
at the point (5,6) the slope = y' = (4 - 10) / (12 - 4) = -3/4
So the equation of tangent line is y - 6 = -3/4( x - 5)
y = -3/4x + 39/4
so the y intercept = =3/4(0) + 39/4 = 39/4 Answer
and x intercept = -39/4 / - 3/4 = 13 Answer
