For number one you do 15-9 which is 6 and that’s the answer
For number to do 25-18 which is 7 and that’s the answer for that one
The true statement is (c) No; the slopes of segment EF and segment DF are not opposite reciprocals.
<h3>
Right triangles </h3>
Right triangles have a pair of perpendicular lines
Coordinates
The coordinates are given as:
- D = (-2,-1)
- E = (-2,2)
- F = (0,0)
<h3>Slopes</h3>
Start by calculating the slopes of lines DF and EF using:
So, we have:
Also, we have:
For the triangle to be a right triangle, then the calculated slopes must be opposite reciprocals.
i.e.
By comparison, the slopes of both lines are not opposite reciprocals.
Hence, the true statement is (c)

Step-by-step explanation
Answer:
<em>We can't find a unique price for an apple and an orange.</em>
Step-by-step explanation:
Suppose, the price of an apple is and the price of an orange is
They need $10 for 4 apples and 4 oranges. So, the first equation will be.......
They also need $15 for 6 apples and 6 oranges. So, the second equation will be........
Dividing equation (1) by 2 on both sides :
Dividing equation (2) by 3 on both sides :
So, we can see that both equation (1) and (2) are actually same. That means, we will not get any unique solution for and here. Both and have <u>"infinitely many solutions"</u>.
Thus, we can't find a unique price for an apple and an orange.
The fraction 91/10 is equivalent1 to 9 1/10.
This fraction is a IMPROPER FRACTION once the absolute value of the top number or numerator (91) is greater than the absolute value of the bottom number or denomintor (10). So, the equivalent fraction is a MIXED NUMBER which is made up of a whole number (9) and proper fraction (1/10).
<span>The fraction 91/10 is equal to 91÷10 and can also be expressed in decimal form as 9.1.</span>
