First thing we need to do is find the slope. since this equation is already in slope intercept form, which is y = mx + b, the slope is already shown. It is 1/2
The slope of the line perpendicular to the given line is the negative inverse of the slope. The negative inverse of 1/2 is -2.
Next, use the slope we determined was the negative inverse ( -2 ) and the given point ( 1,3 ) to write the equation of the line in point slope form. The formula is y − y1 = m(x − x1).
With all the correct numbers plugged in, The equation is:
y - 3 = -2 ( x - 1 )
To find out how many did not raise money, we need to find the percentage that did not raise money and multiply that by the total number of members.
If 95% raised money, 5% did not raise money.
0.05 x 80 = 4 members did not raise money
We start with m < A + m < B = m < B + m < C as the given equation. We can rearrange the two terms on the right hand side to get m < A + m < B = m < C + m < B. From here, subtract m < B from both sides to end up with m < A = m < C. The angle B terms go away entirely. This rule I used was the subtraction property of equality. The next rule to use is the symmetric property to go from m < A = m < C to m < C = m < A. This rule is basically where we can flip the two sides of the equation and the equation is the same.
ANSWER:
$18.90
EXPLAINATION:
To solve, the key word here is "marked down". This means that it is going down by 60%. Subtract 100%-60% which is 40%. Now, always remember that 1% = 0.01. SO 40% will be 0.4.
Multiply 47.25x0.4 = answer
18.90 will be the answer
