Answer:
A proportion is an equality of two ratios.
...
Things to remember
Determine whether the ratio is part to part or part to whole.
Calculate the parts and the whole if needed.
Plug values into the ratio.
Simplify the ratio if needed. Integer-to-integer ratios are preferred.
Answer:
y = 3/4x+7
Step-by-step explanation:
The slope is 3/4 and a point is (-8,1)
We can use point slope to make an equation for the line
y-y1 = m(x-x1)
y-1 = 3/4(x--8)
y-1 = 3/4(x+8)
y-1 = 3/4x +6
Add 1 to each side
y-1+1 = 3/4 x+6+1
y = 3/4x+7
This is in slope intercept form (y=mx+b)
Answer:
One Solution
Step-by-step explanation:
x + 3y = 3
x - y = -3
4y = 6 Subtract to solve by elimination.
y = 
Divide by 4.
x - = -3 Substitute for y in the original equation.
x = - Add .
The answer would have to be 60
The solutions to the given system of equations are x = 4 and y = -9
<h3>Simultaneous linear equations</h3>
From the question, we are to determine the solutions to the given system of equations
The given system of equations are
-8x-4y=4 --------- (1)
-5x-y=-11 --------- (2)
Multiply equation (2) by 4
4 ×[-5x-y=-11 ]
-20x -4y = -44 -------- (3)
Now, subtract equation (3) from equation (1)
-8x -4y = 4 --------- (1)
-(-20x -4y = -44) -------- (3)
12x = 48
x = 48/12
x = 4
Substitute the value of x into equation (2)
-5x -y = -11
-5(4) -y = -11
-20 -y = -11
-y = -11 + 20
-y = 9
∴ y = -9
Hence, the solutions to the given system of equations are x = 4 and y = -9
