Answer:
y =
Step-by-step explanation:
In equations, it's important to complete an operation to both sides because if it is only completed on one then the whole equation will change and the solution will be different so it's an important rule to remember when solving equations that you have to keep the equation balanced.
→ 6 = 4x + 9y
⇒ Minus 4x from both sides to isolate 9y
→ 6 - 4x = 9y
⇒ Make 'y' the subject
→ 9y = 6 - 4x
⇒ Divide both sides by 9 to isolate 'y'
→ y =
So,
For number one, there will be an infinite number of solutions, as there are two placeholders.
3x - 2y = 6
It seems we can use the intercept method.
3x - 2(0) = 6
3x = 6
Divide both sides by 3
x = 2
This is one solution: (2,0)
3(0) - 2y = 6
-2y = 6
Divide both sidees by -2
y = -3
This is another solution: (0,-3)
You should now be able to draw the line.
If you want intercept form for this equation, just manipulate the equation in order to get the y = mx + b form.
Subtract 3x from both sides
-2y = -3x + 6
Divide both sides by -2
For the second problem, simply manipulate the equation.
Distribute
Subtract 2x from both sides
Add 6 to both sides
For the third problem, do the same thing.
We must first multiply both sides by 4.
Distribute
Subtract 4x from both sides
Add 3 to both sides
Divide both sides by 2
The slope of -5x + y = 56 is 5
the slope of x + y = -4 is -1
Answer:
1 1/6
Step-by-step explanation:
2 2/3 = 2+2/3
1 1/2 = 1+1/2
So (2 2/3) - (1 1/2)=2+2/3-(1+1/2)=
2+2/3-1-1/2=1+(2/3-1/2)=1+(4-3)/6=1+1/6=
1 1/6
Answer:
this is quite easy. if the tire is 14 ft. tall, that would mean the diameter is 14 ft. as well (do to a tire being round). the radius is half of the diameter, meaning the radius is 7 ft. finally, to find the circumference, you would have to multiply pi by 2 (6.28) then multiply this by the radius to make 43.98 ft.
Step-by-step explanation:
D = 14
R = 14/2 = 7
C = 2(pi) x 7 = 6.28 x 7 = 43.98
