Answer:
The value of angle XWY = 70°
Step-by-step explanation:
=> angle XYZ + angle XYW = 180° { linear pair }
=> angle XYW + 115° = 180°
=> angle XYW = 180° - 115°
=> angle XYW = 65°
Now angle WXY + angle XWY + angle XYW = 180° { sum of angles of a triangle is 180° }
=> 45° + 65° + angle XWY = 180°
=> angle XWY + 110° = 180°
=> angle XWY = 180° - 110°
=> angle XWY = 70°
Answer:
X->-infinite, graph is positive +(infinite)
X-> + infinite, graph is negative (-infinite)
Step-by-step explanation:
When you study end behaviour of a polynomial, you verify it's highest exponent. If it is odd, like this exercise, it's Y values come from negative infinity to positive infinity. If the coefficient is negative, it is the opposite, it comes from positive infinite to negative infinite.
A relation can only be a function if every x-value only has one y-value.
For answer A, x = -3 returns two y-values of -3 and -5, so it cannot be a function.
For answer B, x = 2 returns two y-values of 3 and 5, so it cannot be a function.
For answer C, x = 2 returns two y-values of -1 and 1, and x = 3 returns two y-values of -4 and 4, so it cannot be a function.
The answer is D, as no x-value returns two y-values in the table.
Answer:
<h2>Length = 13 in.
</h2>
Step-by-step explanation:
perimeter of a rectangle (P) = 2L + 2W
where;
P = 42 in.
Length (L) = 5 + W
Find:
length (L) of the rectangle
solution:
P = 2L + 2W
42 = 2(5 + W) + 2W
42 = 10 + 2W + 2W
42 - 10 = 4W
32 = 4W
W = 32/4
W = 8
Length (L) = 5 + W
= 5 + 8
= 13 in
proof:
42 = 2(13) + 2(8)
42 = 42 in
