Answer:
y=-13
Step-by-step explanation:
Plugging in -7:
y= (-7)2 + 1
-7 * 2 = -14
So:
y= -14 + 1
-14+1=-13
Jill = x
Jack = x + 1 1/3
X = 5 1/2
Solving Equations
5 1/2 +1 1/3
=6 5/6
Answer = 6 5/6 hours
<span>We need to find the correct answer on the given choices:
If a >
0 and b < 0, then The answer is a + b > 0
let’s give a specific example:
let’s have a = 1
and b = .20
</span>
<span>Now,
let’s try calculating if our answer is correct.
Thus a + b > 0
=> a + b
=> 1 + .20
=> 1.20
and 1.20 is greater than 0.
=>Therefore 1.20 > 0 = a + b > 0</span>
92°. The angles in a triangle always add up to 180°.
A helpful way to remember what the interior angles add up to in any polygon is with this formula:
180 (n - 2), where n is the number of sides.
For example, with a triangle: 180 (3 - 2) = 180 (1) = 180. The interior angles in a triangle all add up to 180.
With a rectangle/quadrilateral: 180 (4 - 2) = 180 (2) = 360.
