Answer:
y=9
Step-by-step explanation:
slope is (y2-y1)/(x2-x1), so we plug in the values. (-4-y)/(0 - (-2)). so we get -4-y/2 since zero minus negative 2 is positive 2. given the slope is -13/2, -4-y must be equal to negative 13. So we set an equation of -13 = -4 - y. We add 4 to 13, and get -9 = -y. We multiply each side by a -1, and we get y equals 9.
We can check this by plugging 9 back into our original slope equation. (-4-9)/(0-(-2) which gives us -13/2.
Answer:972
Step-by-step explanation:
Divide both numbers by 972 and they both go into each other
We have the following:
1.
let x a tulips
let y daffodils
therefore:

solving:

for x:

Therefore, the answer is 5 tulips and 10 daffodils
2.
let x a 30% silver
let y a 55% silver

solving:

for x:

Therefore, the answer is 480 pounds of 30% silver and 320 pounds of 55% silver
Answer:
162
Step-by-step explanation:
2/3(3^(-4)) is the way you would work out the sum
16 is 25 percent of the number so if you multiply 4 on top and bottom, you get 64.
