Answer:
Step-by-step explanation:
because both equations do not have matching numbers for the x or y variable, and both equations are positive you are going to have to multiply each equation by a number so that there will be at least one variable with the same number but with opposite signs.
it does not matter which variable you choose.
lets use y because 2 and 3 are smaller then 2 and 5.
so lets multiply the first equation by 2 in order to get y equal to 6.
2(2x)+2(3y)=(2)6
(do not forget to multiply what the equation is equal to also)
4x+6y=12
now for the second equation we need y to equal negative 6
-3(5x)+-3(2y)=-3(4)
-15x-6y=-12
now lets put the 2 new equations next to each other and see what we can cancel out
4x+6y=12
-15x-6y=-12
-11x=0
x=0
now plug 0 in for x and solve for y (it does not matter which of the 4 equations you choose to solve.
2(0)+3y=6
3y=6
y=2
so your answer is x=0, y=2
We can identify that the missing reason in the proof is: Definition of Congruent angles.
<h3>How to give proof of a congruent triangle?</h3>
We know that an angle measure of 90° of ∠ABC in the triangle means that it is a right angle triangle.
We also see that ∠ADB is also a right angle and is equal to 90°.
Now, since they have exactly the same measure, these angles are congruent. Then we can say that the angles are congruent and as such:
∠ABC ≅ ∠ABD
Thus, we can identify that the missing reason is: Definition of Congruent angles.

<h3>
Answer:</h3>
B). y = (x -3)(x +1)(x -1)
<h3>
Step-by-step explanation:</h3>
The zeros of the function are -1, 1, and 3, so the factors are (x +1), (x -1), and (x -3).
Selection B is the only choice that has these three factors.

<em>Comment on zeros and factors</em>
When x = a is a zero of a polynomial function, (x -a) is a factor.
Answer:
Step-by-step explanation:
Least to largest:
First compare the whole parts of the decimal number. The whole part with greater number will be the greatest number.
2) Then compare the decimal parts. Compare tenth place. The decimal number that has greater number in the tenth place will be greater.
3) If the number in tenth place is equal, then compare 100th place and so on
