Answer:
The solution is (0, 3)
Step-by-step explanation:
First, reduce 2x + 4y = 12 to x + 2y = 6, for easier calculations.
Next, substitute y - 3 for x in the other equation:
y - 3 + 2y = 6, or
3y = 9
Then y = 3. Since x = y - 3 in general, x = 3 - 3 = 0 when y = 3.
The solution is (0, 3)
Answer:
10 songs
Step-by-step explanation:
Let number of songs Craig and Jeff downloaded be s
5.50 + 0.25s = 0.80s
5.50 = 0.55s
s = 10
Substitute the given values for the parameters in the point-slope form of the equation of a line. That form is
y - k = m(x - h)
for point (h, k) and slope m.
You have (h, k) = (1, 2) and m=-3, so your equation is
y - 2 = -3(x - 1)
Answer: (A) linear decrease
Step-by-step explanation:
linear decrease is when something empties for the same rate.
Answer:
3x-x+2=4
Step-by-step explanation:
$15 + .5($10), or $20 total.
Since the books normally cost $25 total normally, Joseph paid $20/$25%, or 80% of both books (saving 20%)
