Answer:
value of a in terms of b and c is: 
Option D is correct.
Step-by-step explanation:
We are given:
We need to find a in terms of b and c
We have: 
Put value of d 
So, value of a in terms of b and c is:
Option D is correct.
Answer:
A) y = 1/3x + 4
B) y = 1/2x - 9
Step-by-step explanation:
A) In order to find this, we must first solve the initial equation for y to get the slope.
-x + 3y = 6
3y = x + 6
y = 1/3x + 2
Now we know the slope to be 1/3 since parallel lines have the same slope. So we take this slope and the point and use point-slope form to find the equation.
y - y1 = m(x - x1)
y - 5 = 1/3(x - 3)
y - 5 = 1/3x - 1
y = 1/3x + 4
B) To find this line, we again have to find the slope of the initial equation by solving for y.
2x + y = -4
y = -2x - 4
Now we know our new slope to be 1/2. This is because perpendicular lines have opposite and reciprocal slopes. We can use this and the point to solve in the same way.
y - y1 = m(x - x1)
y - - 8 = 1/2(x - 2)
y + 8 = 1/2x - 1
y = 1/2x - 9
Isn't that simply asking you to compute 30% of 20?
30 x
----- = ------
100 20
100x = 600
x = 6
So, out of those 20 numbers, you would expect that 6 of them would begin with the digit 1.
Answer:
12 students from math club
Step-by-step explanation:
Number of vans = 2
Number of students in each van = 6
Number of students who went from math club to the soap box = ?
You can apply the following expression:
Total number of students=Number of students per van * Number of vans
Total number of students= 6 *2
= 12 students from math club....
