Answer:
<em>The coordinate of the midpoint is 1/2</em>
Step-by-step explanation:
<u>Midpoint</u>
The midpoint of a segment defined in a one-dimension system is

Where x1 and x2 are the coordinates of the points.
The given segment has endpoints x1=-7 and x2=8, thus:


The coordinate of the midpoint is 1/2

Answer:
Step-by-step explanation:
Solving Exponential Equations with Different Bases.
Step 1: Determine if the numbers can be written using the same base. If so, stop and use Steps for
Solving an Exponential Equation with the Same Base. If not, go to Step 2.
Step 2: Take the common logarithm or natural logarithm of each side.
Step 3: Use the properties of logarithms to rewrite the problem. Specifically, use Property 5 which
says
Step 4: Divide each side by the logarithm.
Step 5: Use a calculator to find the decimal approximation of the logarithms.
Step 6: Finish solving the problem by isolating the variable.
Given: In ΔDEF and ΔDGF, Side DF is common.
To prove congruent of the triangle, we must require the minimum three conditions; like two sides and one angle of one triangle should be equal to the other triangle. OR Three sides of one triangle should be equal to the other triangle. OR Two angles and one side of one triangle should be equal to the other triangle. etc.
As per given question, to prove congruent of given triangles by SAS property then we should have given two sides and one angle of one triangle should be equal to the other triangle as additional information.
Since, In ΔDEF and ΔDGF, Side DF is common. So, we should require only one side and one angle that should be equal to another triangle.
