Answer:
1. y = 0, b/a
2. y = 0, a/b
3. y =0, c/b
4. y =0, c/a
Step-by-step explanation:
The slope formula for y = mx + b which is known as standard form is Ax + By ≥ C
slope = A/B
x-intercept = C/A
y-intercept = C/B
and now we are dueling with y, so we will use y-intercept
1. cx + ay = b
where c is x, a = y and b=c
Y-int = C/B
y = 0, b/a
2. cx + by = a
y = 0, a/b
3. ax + by = c
y =0, c/b
4. bx+ ay = c
y =0, c/a
Hope this helps
Answer:
Step-by-step explanation:
72 ÷ 4

3 drops per minute
20 drops = 1 ml
How many minutes are there in a day?
60*24 = 1,440 minutes
1,440*3 = 4320 drops
How many milliliters?
4320/20 = 216 ml
Perimeter = 2(l+w) or 2(length+width)
So far you have the width, which is 19feet. Since you have two sides of the rectangle which are 19 feet, add 19+19=38
Subtract 62-38 to get 24.
You now have the length of both of the sides combined. So you need to divide 24/2 = 12
The length of the rectangle = 12ft.
Answer:
On occasions you will come across two or more unknown quantities, and two or more equations
relating them. These are called simultaneous equations and when asked to solve them you
must find values of the unknowns which satisfy all the given equations at the same time.
Step-by-step explanation:
1. The solution of a pair of simultaneous equations
The solution of the pair of simultaneous equations
3x + 2y = 36, and 5x + 4y = 64
is x = 8 and y = 6. This is easily verified by substituting these values into the left-hand sides
to obtain the values on the right. So x = 8, y = 6 satisfy the simultaneous equations.
2. Solving a pair of simultaneous equations
There are many ways of solving simultaneous equations. Perhaps the simplest way is elimination. This is a process which involves removing or eliminating one of the unknowns to leave a
single equation which involves the other unknown. The method is best illustrated by example.
Example
Solve the simultaneous equations 3x + 2y = 36 (1)
5x + 4y = 64 (2) .
Solution
Notice that if we multiply both sides of the first equation by 2 we obtain an equivalent equation
6x + 4y = 72 (3)
Now, if equation (2) is subtracted from equation (3) the terms involving y will be eliminated:
6x + 4y = 72 − (3)
5x + 4y = 64 (2)
x + 0y = 8
