Answer:
A) -2
Step-by-step explanation:
Answer:
(-2/3, -13/3)
Step-by-step explanation:
Given the expressions;
Equating both expressions;
Collect the like terms:
Substitute into any of the expressions to get 'y'
Hence the solution to the equation is (-2/3, -13/3)
the sum of the interior angles is 180° (triangles)
it's isosceles, 2 equal sides and 2 equal angles.
you take away the given angle from 360° and you will find the sum of the 2 equal sides, you divide by 2 and you have the angle b (equal to angle C).
(180 - 72) : 2 =
108 : 2 = 54° (your answer)
-----------------------
72 + 54 + 54 = 180°
The answer is good.
Answer:
2/3
Step-by-step explanation:
(1- (-5))/(2-6)=
(6/-4)=
-3/2
perpendicular means reciprocal so the slope would be 2/3
Step 3 is wrong because when dividing exponents you subtract them x^-10 would be multiplying by x^-12 making it x^-10-12 and that would be x^-22 same applies for the y exponents
