The answer is: y = -2x+12
4x+2y=24=
4x-4x+2y=24-4x=
2y=24-4x
Divide each piece by 2=
2y/2=24/2-4x/2
y=12-2x
But, slope intercept form is y=mx + b so you must put the second part in reverse, making the answer to the equation be y=-2x+12
(Don't forget the - on -2)
All this is asking you is to find how much you need to save per month (limit of 5) in order to make your goal of $1200.
To solve this, simply divide 1200 by 5, which is the months, and you get $240, which is how much you have to save per month in 5 moths to reach your exact goal of $1200. If anything is confusing please ask :)
The angle is 60° because it is one of three angles that make up an equilateral triangle.
Hope this helps! :)
Answer: 1.8 servings of soybean and 1.2 servings rice will be needed.
Step-by-step explanation:
Let x be the number of soybeans and y be the number of rice.
Then , According to the question , we have
Multiply 2 on both the sides of equation (2), we get
Subtract equation (2) from equation (3), we get
Put x = 1.8 in equation (2), we get
Hence, 1.8 servings of soybean and 1.2 servings rice will be needed.
Answer:
x = 3/4
Step-by-step explanation:
f(x) = -2×2 +4x +1
f(x) = -4 +4x +1
f(x) = 4x -3
3 = 4x
3/4 = x
x= 3/4
