Answer:
Im sure that the answer is c
Answer:
y = - x +
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 )
y = x + 1 ← is in slope- intercept form
with slope m =
Given a line with slope m then the slope of a line perpendicular to it is
= - = - = - , thus
y = - x + c ← is the partial equation
To find c substitute (- 5, 11) into the partial equation
11 = + c ⇒ c = 11 - =
y = - x + ← equation of perpendicular line
The difference between the points (6,-6) and (2,-2) is (4,-4)
Answer: Liza invested $15000 at 3% and $30,000 at 4%
Step-by-step explanation:
Let x be the amount invested by Liza at 3% interest then the amount she invested in 4% interest will be 2x.
We know that the compound interest with principal P is give By
, where n is the number of period.
Now, interest earned in 3% (in decimal 0.03) account in 1 year is given by:-
Similarly, interest earned in 4% (in decimal 0.03) account in 1 year is given by:-
According to the question,
Also, 2x=2(15000)=30000
Therefore, Liza invested $15000 at 3% and $30,000 at 4% .
