Rearrange so 4y= -3x-24 then divide everything by 4so,
Y=-3x/4 - 6. The intercept is -6
Answer:
[130-5(13)] (13) = $845 max revenue.
Step-by-step explanation:
If the number of books sold = 130-5p then revenue will be (130-5p)p = -5p^2+130p
the maximum can be found by graphing or by the fact that the max will be -b/2a = -130/-10 = 13 dollars/book
[130-5(13)] (13) = $845 max revenue.
The whole bill is $31.99 that is 100%. You can use mental math to determine exatcly 15% from $31.99:
1. 15%=10%+5%
2. To find 10% from $31.99 you should simply divide $31.99 by ten. Thus, 10% from $31.99 is $3.199.
3. 5% is half of 10%, then 5% from $31.99 is $3.199:2=$1.5995.
4. 15% from $31.99 is $3.199+$1.5995=$4.7985≈$4.80.
Answer: correct choice is B.
Answer:
k= 1316/117
Step-by-step explanation:
Answer:
the 4th graph.
Step-by-step explanation:
by solving for Y in the first equation, we get the y-intercept of -1 and the second equation has a y-intercept of 1. 4th graph is the only graph with those 2 intercepts
