Answer:
Step-by-step explanation:
TO find the value for the terms, substitute n for the number in the sequence. so
for 1st term n = 1
for 2nd term n =2 etc.
1st Term = 1^2-3 = 1-3 = -2
2nd term = 2^2 - 3 = 4-3 = 1
3rd Term = 3^2 - 3 = 6
10th Term = 10^2 - 3 = 100 - 3 = 97
Hope this helps
what is the average cost of 7 articles if 3 of them cost 30k each and the rest cost 12.5k each
TOTAL NUMBER OF ARTICLE= 7
ARTICLES FOR 30K = 3
ARTICLES FOR 12.5K = 7-3= 4
Average cost of 7 articles
Answer:
y + 2 = ⁶/₅(x - 5) {the point-slope form of the equation}
y = ⁶/₅x - 8 {the slope-intercept form of the equation}
6x - 5y = 40 {the standard form of the equation}
Step-by-step explanation:
The point-slope form of equation is: y - y₀ = m(x - x₀), where (x₀, y₀) is any point the line passes through and m is the slope.
m = ⁶/₅
(5, -2) ⇒ x₀ = 5, y₀ = -2
So, the point-slope form of the equation:
y + 2 = ⁶/₅(x - 5)
Therefore:
y + 2 = ⁶/₅x - 6 {subtract 2 from both sides}
y = ⁶/₅x - 8 ← the slope-intercept form of the equation
-⁶/₅x + y = - 8 {multiply both sides by (-5)}
6x - 5y = 40 ← the standard form of the equation
Answer:
7· 5n + 55 ≥ 100 is required inequality
Step-by-step explanation:
Let he visit be theater x time
→ for new movie ticket
→55+7·5xn≥100
→7·5n+55≥100
Hence, 7· 5n + 55 ≥ 100 is required inequality
