Answer:
C) P(1, -26/7)
Step-by-step explanation:
You want the weighted average of A(-4, 2) and B(3,-6) using weights 2 and 5, respectively.
<h3>Weighted average</h3>
Each of the values is multiplied by the corresponding weight, and the sum of those products is divided by the total of the weights to obtain the weighted average.
P = (2A +5B)/(2+5)
P = (2(-4, 2) +5(3, -6))/7 = (-8 +15, 4 -30)/7 = (7, -26)/7
P = (1, -26/7)
The coordinates of P are (1, -26/7).

Step-by-step explanation:
so first ur oging to add the five then the 6
The domain values uniquely map to the dependent variable.
A function that fits these values is f(x)=20x+1020.
Answer:
p=5
Step-by-step explanation:
if 5+3 = 8
13-8=5
and both sides of the triangle need to be the same
Answer:
The expression is: 100 -a - 2b
Step-by-step explanation:
One piece of length a and two pieces of length b, i.e., (2 times b) are a total length of (a + 2b). We are asked to express the remaining part of the wire, originally 100 cm long, so that must be 100 minus the total pieces cut out:
100 - ( a + 2b ) = 100 -a -2b
