The answer is no because the numbers are repeated
Y = -x^2 + x + 2
y = -x + 3
-x + 3 = -x^2 + x + 2
x^2 - x - 2 - x + 3 = 0
x^2 -2x + 1 = 0
(x - 1)(x - 1) = 0
x - 1 = 0 y = -x + 3
x = 1 y = -1 + 3
y = 2
solutions are : (1,2) , (1,2)
Answer:
m∠1 = 112°
Step-by-step explanation:
To solve for m∠1, we need to find the supplementary angle and subtract from 180°. We also know that m∠2 = 44° and the remaining two angles inside the triangle are the same because of the congruent sides, let's call each angle x.
Therefore m∠2 + x + x = 180; combine x's
m∠2 + 2x = 180; substitute m∠2 = 44°
44 + 2x = 180; subtract 44 from both sides
2x = 136; divide by 2
x = 68°
Therefore using the supplementary angle
x + m∠1 = 180 (because it is supplementary)
68 + m∠1 = 180; subtract 68 from both sides
m∠1 = 112°

Starting woth the ones place 6 + 1 + 2 = 9, because, the sum of the digits in the ones place is not upto 10, we will not regroup the ones place.
Thus, the answer to 13a is NO
Since, we did not regroup the ones place, there is no regrouped tens to add, thus the answer to 13b is NO.
Next, for the tens place, 4 + 2 + 5 = 11, because the sum of the digits in the ones place is upto 10, we regroup the tens place.
Thus, the answer to 13c is YES.
</span><span>Since, we regrouped the ones place, we add the regrouped hundred, thus the answer to 13b is YES.
Finally, for the hundred place, 1 + 3 + 4 + 1 = 9
Therefore, the sum of
