Answer:
B and A
Step-by-step explanation:
The diagonals of a rhombus bisect each other at right angles, thus
(3)
y = x + 3 → (1)
3x + 2 = y + 1 → (2)
Substitute y = x + 3 into (2)
3x + 2 = x + 3 + 1
3x + 2 = x + 4 ( subtract x from both sides )
2x + 2 = 4 ( subtract 2 from both sides )
2x = 2 ( divide both sides by 2 )
x = 1 → B
(4)
Substitute x = 1 into (1)
y = 1 + 3 = 4 → A

Step-by-step explanation:
The formula that relates the length of a ladder, L, that leans against a wall with distance d from the base of the wall and the height h that the ladder reaches up the wall is L = StartRoot d squared + h squared EndRoot. What height on the wall will a 15-foot ladder reach if it is placed 3.5 feet from the base of a wall?
L = √d² + h²
Answer:
Every integer is a rational number, since each integer n can be written in the form n/1. For example 5 = 5/1 and thus 5 is a rational number. However, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
