13x+6y = -30................y = -5 -13x/6
x−2y=−4...................... y = x/2 +2 <span>
If we graph both lines we can get the solution of the system (point of intersection)
The best estimate is (x,y) = (-2.625, 0.688)</span>

Answer:
R(n)=100,000(0.5)^n
Step-by-step explanation:
Solve each equation separately:
(-1, 3) Has to be a point that fits both equations
y = 2x + ____
Plug in Values:
3 = 2(-1) + ____
3 = -2 + ____
___ = 5
First Blank: 5
y = ___x - 1
Plug in Values:
3 = ___(-1) - 1
4 = ___(-1)
___ = -4
Second Blank: -4
Answer:
She can only make 5/6 of her recipe with the amount of milk that she has.
Step-by-step explanation:
Some data of this problem is missing, the data missing is:
Her recipe calls for 3/4 of a pint of milk and she only has 5/8 of a pint of milk.
Now, to know what's the portion she can do with that amount we need to divide the amount of milk she has by the total amount she needs:
÷
When we divide we turn the second fraction upside down (the numerator becomes the denominator and viceversa) and multiply, thus:
÷
×
If we simplify this last expression we have:
Thus, she can only make 5/6 of her recipe with the amount of milk that she has.
<em>Note: In case the data missing is different, you can apply this same procedure with the fractions you have. </em>
