And can anyone do this?!!
1 answer:
a. The interest earned will be $36.
b. The account balance will be $336.
Step-by-step Explanation:
Step 1:
The initial amount put into the account was $300.
This account has an interest rate of 4% every year. So we must calculate how much 4% of $300 is.
4% of $300 =
Step 2:
So for every year, the interest of $12 is added into the account. To calculate total interest we multiply this interest amount and the number of years.
So after 3 years
So account balance after 3 years .
So the interest earned is $36 and the account balance is $336 after three years.

Given:
The given equation of line is
To find:
The equation of line that passes through (-5,4) and is parallel to the given line.
Solution:
Slope intercept form of a line is
...(i)
where, m is slope and b is y-intercept.
We have,
...(ii)
On comparing (i) and (ii), we get
Slope of given line is .
Slope of parallel lines are same. So, slope of parallel line is .
The required line passes through (-5,4) with slope . So, the equation of line is
Adding 4 on both sides, we get
Therefore, the correct option is a.
A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The vertex B is at (1, 5), then vertex B' is at (-2, 11).
<h3>What is a triangle?</h3>A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The sum of all the angle of a triangle is always equal to 180°.
∆ABC is translated 6 units up and 3 units left to create ∆A'B'C'.
The vertex A is at (-1, 2), then vertex A' is at,
A' = (-1-3, 2+6) = (-4, 8)
The vertex B is at (1, 5), then vertex B' is at,
B' = (1-3, 5+6) = (-2, 11)
