<em>Answer:</em>
<em>In my opinion the answer is </em><em><u>y = 6</u></em>
<em>Step-by-step explanation:</em>
<em>We have two unknowns from the equation therefore, two equations are needed. These equations are:
</em>
<em>
</em>
<em>3x + y = 9 </em>
<em>y = –4x +10 </em>
<em>
</em>
<em>To solve for y, we first substitute the second equation to the first one.
</em>
<em>3x + –4x +10= 9 </em>
<em>x = 1
</em>
<em>
</em>
<em>We substitute the value of x to either of the equations and solve for y.
</em>
<em>
</em>
<em>y = –4(1) +10 </em>
<em>y = 6</em>
I think its d, because A and Cs angles make 180. And B has two equal sides that make it possible to make a triangle. Sorry i couldnt be more helpful
Check the picture below, so the circle looks more or less like so, with a radius of 9.
Let, the numbers are: x, (x+2), (x+4)
Now, x+x+2+x+4 = -27
3x + 6 = -27
3x = -33
x = -11
So, (x+2)=-11+2 = -9, (x+4) = -11+4 = -7
In short, Your Final answer would be -7,-9 and -11
Hope this helps!
Answer:
---- Set Builder
(50, ∞) ---- Interval Notation
Step-by-step explanation:
Given
x > 50
Required
Write as a
- Set builder
- Interval notation
As Set Builder:
x > 50 means that x is an integer and x is greater than 50.
In set builder notation, integers are represented with z.
So, the above can be represented as:
This translates to:
x is a member of the set of integers such that x is greater than 50
As Interval Notation:
In interval notation, we make use of brackets to represent the intervals.
In this case > is represented by (a,b)
Where a and b are the intervals of the notation
Since x > 50, then a = 50 and b = ∞ because we only know the starting point and not the end point.
<em>Hence: x > 50 in interval notation is (50, ∞)</em>
