Answer:
-16
Step-by-step explanation:
-k² -(3k-5n)+4n k=-1 , n= -2
= -(-1)² - ( 3(-1) -5(-2) )+4(-2)
= -1-(-3+10)-8
= -1-(7)-8
= -1-7-8
= -16
Answer:
y = - 2x - 10
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 2, thus
y = - 2x + c ← is the partial equation
To find c substitute (- 6, 2) into the partial equation
2 = 12 + c ⇒ c = 2 - 12 = - 10
y = - 2x - 10 ← equation of line
x^2 - y^2 - 2y - 1
x^2 - (y+1)^2
Answer:
0.62 = 0.62 × 100/100 = (0.62 × 100)/100 = 62/100 = 62%;
In other words:
1) Multiply that number by 100.
2) Add the percent sign % to it.
Inadequate problem statement. I'm assuming you meant "find the number of bananas lost in a 20% decrease from 160 bananas." That would be 0.20(160), or 32 bananas lost, with 128 bananas remaining. Please include all details when you share a problem statement.
