The answer is C. 2x+3y=12
Answer:
y = 2x - 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
here m = 2 and b = - 4
y = 2x - 4 ← equation of line
9514 1404 393
Answer:
Step-by-step explanation:
Let x and y represent amounts invested at 6% and 9%, respectively.
y = 3x +58 . . . . . . . the amount invested at 9%
0.06x +0.09y = 1097.19 . . . . . . total interest earned
__
Substituting for y, we have ...
0.06x +0.09(3x +58) = 1097.19
0.33x + 5.22 = 1097.19 . . . . . . . . . simplify
0.33x = 1091.97 . . . . . . . . . . . . subtract 5.22
x = 3309 . . . . . . . . . . . . . . . . divide by 0.33
y = 3(3309) +58 = 9985
$3309 is invested at 6%; $9985 is invested at 9%.
Answer:
$23.80 per pair, $190.4 for 8 pairs
Step-by-step explanation:
a. assuming each pair of jeans is the same price, just divide the total by 3. the price per pair is 71.40/3, which is $23.80 per pair
b. simply multiply the price of one pair of jeans, as found above, by 8. 23.80*8 is $190.4 for 8 jeans
hope this helped!
Answer:
-0.523
Step-by-step explanation:
log(a/b)=loga-logb
log (0.3) can be written as log (3/10).
=log(3/10)
=log3-log10
=0.477-1 (log3=0.477 and log10=1)
= -0.523
