Answer:
y = -2x - 3
Step-by-step explanation:
Slope: (5 - - 5)/(-4 -1) = 10/-5 = -2
y-intercept: 5 - (-2)(-4) = -3
The answer is : y=-6-47

Answer:
The addition of 4 liters of 25% solution to 6 liters of 50% solution produces 10 liters of 40% solution.
Step-by-step explanation:
Hope this helps.
Super sorry if it doesn't.
2x - y = -24
x + 7y = 3
Solve one equation for a variable and plug the resulting value into the second equation.
x + 7y = 3 Subtract 7y from both sides
x = -7y + 3
Now, plug that x-value into the x of the first equation.
2x - y = -24 Plug in the x-value
2(-7y + 3) - y = 24 Use the Distributive Property
-14y + 6 - y = -24 Combine like terms (-14y and -y)
-15y + 6 = -24 Subtract 6 from both sides
-15y = -30 Divide both sides by 15
y = 2
Next, plug the y-value back into the second equation.
x + 7y = 3 Plug in the y-value
x + 7(2) = 3 Multiply
x + 14 = 3 Subtract 14 from both sides
x = -11
y = 2 and x = -11
Answer:
1/4 + 1/4 + 1/4 or 1/8 +1/8 +1/8 +1/8 +1/8 +1/8
Step-by-step explanation:
To decompose a fraction simply means to take it apart. The most basic way to decompose a fraction is to break into unit fractions, which is when the numerator (top number) is 1. We can see that 6/8 is the same as the unit fraction 1/8 six times.
