Answer:
75 units²
Step-by-step explanation:
PL² = 6² + 8²
PL² = 100
PL = 10
Triangles PAL and MPL are similar triangles
6/8 = PM/10
PM = 10 × 6/8 = 7.5
Area = 7.5 × 10
75 units²
7x+11 = 3x-5
4x+11 = -5
4x = -16
X = -4
Irrational numbers. √7 is an irrational number.
Answer:
Step-by-step explanation:
Note that the four input values, {3,4,6,11}, are all unique. Each has exactly one y value associated with it. This is an important criterion when we're deciding whether a relation is a function or not.
Suppose that we added one more input and its associated output:
{3,4,4,6,11}
If it happened that different values of y were associated with the two 4's, then we know immediatel that this relation is not a function.
