Answer:
y = √ x + 4
The domain of a function is the value in which you put in the function will make it undefined.
To find the domain equate the function to zero
That's
√x + 4 = 0
square both sides
x + 4 = 0
x = - 4
The domain of the function is x E R except - 4
Hope this helps
Answer:25
Step-by-step explanation:
The first statement, XZ ⊥ XY and XY = XZ = 5 proves that the triangle XYZ is isosceles.
One isosceles triangle has two congruent sides and two congruent angles.
And you should also know the theorem that states that if two sides of a triangle are congruent then the two angles opposite that sides are also congruent.
<span>So, given that the two sides XZ and XY are congruent, their opposite sides are also congruent, and that proves that the the triangle is isosceles.</span>
If you round your numbers that is how you find your answer. Rounding rules: 5 or more round up to the next number. 4 or less stays the same. This problem requires you to round to the whole number.
1.25 rounds to 1
-2.69 round to -3
so the answer is 1 + (-3)
Not quite sure but:
2/3 = 3/4
divide all by 2/3 to get a 1 value so
1 = 0.8
