Answer:
slope = -1.5
Step-by-step explanation:
A set of three or more points are said to be collinear if they all lie on the same straight line.
We have been given the following collinear set of points;
P(0, 3), Q(2, 0), R(4, -3)
This implies that P, Q, and R lie on the same line.
The slope of a line is defined as; (change in y)/(change in x)
Using the points P and Q, the slope of the line is calculated as;
(0-3)/(2-0) = -3/2 = -1.5
Answer:
-3/2
Step-by-step explanation:
Answer:
50
Step-by-step explanation:
When you around to the nearest ten, you look at the ones digit, which in this case, is 8. Since that is 5 and above, you would have to round the 4 in the tens digit up to 5, resulting in 50.
The cost for 12 square feet is $51.
An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Cost for 16 square feet = $68
Now,
The cost for 12 square feet.
= 12 x (68/16)
= 3 x 68/4
= 3 x 17
= $51
Thus,
The cost for 12 square feet is $51.
