Carmen deposits $700 into an account that pays simple interest at a rate of 3% per year. How much interest will she be paid in t
VLD [36.1K]
First we need to find what 3% of 700 is.  We know 10% is 70, 5% is 35, so we need to find out what 3% is.  If you don't know how to calculate percentages of a number, I recommend starting with 10%.  This way you know 10% of the number is 70, so you will also know that 1% of the number is 7.  7 x 3 = 21.  So 3% of 700 is 21.  Since it was over 6 years, we multiply 21 x 6.  That gives us 126.  She will be paid $126 in interest in the first six years.

7. Find an equation of the line containing (- 4,5) and perpendicular to the line 5x - 3y = 4.
bagirrra123 [75]

The equation of the line containing (- 4,5) and perpendicular to the line 5x - 3y = 4 is y = -3 / 5 x + 13 / 5

<h3>How to find the equation of a line?</h3>

The equation of a line can be represented as follows:

y = mx + b

where

  • m = slope
  • b = y-intercept

Therefore, the equation passes through (-4, 5) and perpendicular to 5x - 3y = 4

Hence,

perpendicular lines follows the rule below:

m₁m₂ = -1

Hence,

5x - 3y = 4

5x - 4 = 3y

y = 5/ 3 x - 4 / 3

m₁ = 5 / 3

5/3 m₂ = -1

m₂ = - 3 / 5

Hence,

using (-4, 5)

5 = - 3 / 5 (-4) + b

5 = 12 / 5 + b

b = 5 - 12 / 5 = 25 - 12 /5 = 13 / 5

Therefore,

y = -3 / 5 x + 13 / 5
