Answer:
(-2,9) ,(4,-3)
Step-by-step explanation:
Given the expression 2x+y=5
We are required to look for values of x and y such that when substituted into the given expression will result in the number 5
The Pairs are (-2,9) ,(4,-3)
Let us plug in the values to check
1. (-2,9)
2(-2)+9=5
-4+9=5
5=5 true
2. (4,-3)
2(4)+(-3)=5
8-3=5
5=5 true
Answer:
a)Number of terms =15
Value of sum =
(b)Number of terms =6
Value of sum
Step-by-step explanation:
A.
nth term,
a=5, r=
Simce the bases are the same, the powers are equal.
n-1=14
n=14+1=15
Number of terms =
15
Value of sum =
B.
nth term,
a=,
Simce the bases are the same, the powers are equal.
4+n-1=9
n=9+1-4=6
Number of terms =
6
Value of sum
NOTE: For the sum, we desire an expression that gives the exact value, rather than entering an approximation
Answer:
Monday
Step-by-step explanation:
Day 1 (Monday):
10 minutes to seconds: 10 x 60 = 600 seconds
= 0.67 m/s
Therefore day 1 she ran at 0.67 m/s
Day 2 (Tuesday):
25 minutes to seconds: 25 x 60 = 1500 seconds
= 0.55 m/s
Therefore day 2 she ran at 0.55 m/s
She was faster day 1 (Monday)!
