For a system of equations such as this, add both of the equations together. The d values will cancel each other out, making 2e=-4. This means that e=-2. If you plug this into one of the equations, you will have d + (-2) = 1. Isolate the variable by adding -2 to both sides: d=3. Written in the format described above (d,e), your answer is (3, -2).
Answer:
45
Step-by-step explanation:
Here is a reference to the Inscribed Quadrilateral Conjecture it says that opposite angles of an inscribed quadrilateral are supplemental.
Explanation:
The conjecture, #angleA and angleC# allows us to write the following equation:
#angleA + angleC=180^@#
Substitute the equivalent expressions in terms of x:
#x+2+ x-2 = 180^@#
#2x = 180^@#
#x = 90^@#
From this we can compute the measures of all of the angles.
#angleA=92^@#
#angleB=100^@#
#angleC=88^@#
<span>#angleD= 80^@#</span>
An isosceles triangle is one having two of its sides equal.
Answer:
x^2=12x-32
Step-by-step explanation:
try to factor by splitting the middle term example x^2-(12*x-32)=0
multiply the coefficient of the first term by the the constant 1 X 32=32
find two factors of 32 whose sum equals the coefficient of the middle term which is answer keys -32 +-1 =-33
-16+-2=-18
-8+4=-12.
