Answer:
Step-by-step explanation:
Given:
The two points on the line are and
.
The slope of the line joining two points and
is given as:
Here,
∴
Equation of line with a point and slope
is given as:
Plug in -2 for , 3 for
and -7 for
. This gives,
Therefore, the equation of the line in vertex form is .
Answer:
13) ⇒
15) ⇒
Step-by-step explanation:
Given expression:
13)
15)
Write the expressions in radical form.
Solution:
For an expression with exponents as fraction like
the numerator represents the power it is raised to and the denominator
represents the nth root of the expression.
For an expression with exponents as negative fraction like
We take the reciprocal of the term by rule for negative exponents.
So it is written as:
using the above properties we can write the given expressions in radical form.
13)
⇒ [Using rule of negative exponents]
⇒ [writing in radical form]
15)
⇒ [Since 2nd root is given as
in radical form]
