Answer: 1. A) 2/5 B) X= -5 Y= 2

3. A) -2/3 B) X= -3 Y= -2

Step-by-step explanation: A) Look where the line intersects perfectly through a corner of one of the boxes, find the next one closes to that count how many it goes up and how many across. Rise/Run so the amount it goes up goes on the top of the fraction and the amount across on the bottom of the fraction.

The area of the given trapezoid is 38 in².

<h3>What is a trapezoid?</h3>

A trapezoid is a quadrilateral (has four sides and four angles) with a single pair of parallel sides. The area (A) of a trapezoid is given by:

A = (1/2) * (a + b) * h

Where a, b are the parallel sides and h is the height of the trapezoid.

Given that a = 8, b = 11, h = 4, hence:

A = (1/2) * (8 + 11) * 4 = 38 in²

The area of the given trapezoid is 38 in².

Write the first five terms of the arithmetic sequence.
hjlf

Answer:

a1 = 4

a2= -2

a3 = -8

a4= -14

a5= -20

Step-by-step explanation:

a12= a1 + 11d

-62 = 4 + 11d

-62-4 = 11d

-66= 11d

d = \frac{-66}{11}\\

  = -6

a1 = 4

a2 = 4 - 6 = -2

a3 = 4 - (6×2) = -8

a4 = 4 - (6×3) = -14

a5 = 4 - (6×4) = -20
