Answer:
Step-by-step explanation:
From the condition of perpendicularity, for two lines to be perpendicular to each other the product of their gradients must equal to ( -1 ).
Same time, equation of a straight line is ; y = mx+ c where m us the gradient and c is the point of intersection of the line on y axis. Therefore, the gradient of this equation m1 ,= -5 and the gradient m2 of the second line will be 1/5. Therefore, the equation of the second line perpendicular to
y = -5x + 6 ; y = x/5 + 6 .
Therefore, y = x/5 + 6 is the new equation.
The answer is B Sometimes

Answer:The simple interest rate is 7.50%
Step-by-step explanation:
Simple interest, I =( P × T × R) / 100
Where P= Principal investment
T = Time in years
R = rate
Given
P= 981.60
I = 1000 - 981.60 = 18 .40
T = 13 weeks = 13 / 52 = 0.25 year
I =( P × T × R) / 100
Cross multiply
I × 100 = P × T × R
18.40 × 100 = 981.60 × 0.25 × R
1840 = 245.4 R
R= 1840 / 245.4
R = 7.498%
To the nearest tenth
R = 7.50%
