1. The ordered of pairs represent some points on the graph of lines m and
1 answer:
Answer:
B
Step-by-step explanation:
slope formula
we have the two points
(2,4) (3,7)
which means the slope for line m is 3x
our equation so far looks like this
y=3x+b
plug in a set of numbers to solve for b
let's use (2,4)
4=3(2)+b
4=6+b
b= -2
which means our equation is
y= 3x-2
which is equal to
2= 3x-y
the only answer is then B

Answer:
C. -11,325
Step-by-step explanation:
- To know the answer, is convenient to replace some values of "n" in the sum
.
- The result would appear after adding up every value of the expression
- When n=1, the expression takes the value of (-1):
.
- When n=2, the expression takes the value of (-2):
.
- Following this way, for every n, we will obtain -n, then, the sum will be:
. This sum can actually be expressed as
, which is the result of solving the initial expression of the sum
.
- Finally, the sum of n=-1 to n=-150 equals -11,325.
