Rearrange the equation so m is the independent variable.

7m + 2 = 7n - 5

M = n - 1

Step-by-step explanation:

7m + 2 = 7n - 5

Group like terms

7m = 7n - 5 - 2

7m = 7n - 7

7m/7 = 7n /7 - 7/7

M = n - 1

m=n-1

7m+2=7n-5

7m+2-2=7n-5-2

7m=7n-7

divide both sides by 7 the answer is at the top

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

homozygous. one is homozygous, while two is heterozygous.
