Answer:
{(0, −5), (2, 9), (−3, −26)}
Step-by-step explanation:
You only need to try the first point in each set to eliminate the wrong answers.
a: 7(-5)-5 = -40 ≠ 0
b: 7(2)-5 = 9 ≠ 7
c: 7(0)-5 = -5 . . . matches given point
d: 7(1)-5 = 2 ≠ 3
The third choice is the correct one: {(0, −5), (2, 9), (−3, −26)}.
so
(this is wrong because

When you're talking about equations, 'literal' means 'has letters in it'. 'C' is the only one with any letters in it.
Answer:
15 feet
Step-by-step explanation:
The question talks about;
- A rectangular flower bed whose dimensions are 12 ft by 9 ft
We are required to determine the length of the diagonal
To answer the question, we need to know the following;
- All the angles in a rectangle are right angles
- A diagonal divides a rectangle into two right-angled triangles
- The dimensions of the rectangle acts as the legs of right angled triangle.
Therefore;
Using Pythagoras theorem;
a² + b² = c²
Where, c is the hypotenuse (in this case the diagonal)
a and b are the shorter sides of the right-angled triangle
Therefore;
c² = 12² + 9²
c² = 144 + 81
= 225
c = √225
= 15
Therefore, the length of the diagonal is 15 feet
