<span>3x + 3y = –9
3x – 3y = 21
-----------------add
6x = 12
x = 2
</span>3x + 3y = –9
3(2) + 3y = -9
6 + 3y = -9
3y = -15
y = -5
x = 2 and y = -5
answer: <span>C. (2, –5)</span>
- 16:10
- 24:15
- 40:25
8:5 is just a simplier version of these other ratios
Answer: 60
Step-by-step explanation:
Let the side lengths of the rectangular pan be m and n. It follows that (m-2) (n-2)=
So, since haf of the brownie pieces are in the interior. This gives 2 (m-2) (n-2) =mn
mn- 2m - 2n- 4 = 0
Then Adding 8 to both sides and applying, we obtain (m-2) (n-2) =8
Since now, m and n are both positive, we obtain (m,n) = (5,12), (6,8) (up to ordering). By inspection, 5. 12 = 60
which maximizes the number of brownies in total which is the greatest number.
Hope that helped! =)
Answer:
It's B or C, I can't see it clearly sorry!
Step-by-step explanation:
<span>You are given the graph of four straight lines, P, Q, R, and S. You are asked to find which line corresponds to the function of f(x) = 4x - 3. The easiest way to answer this is to plug in the values of the coordiante points used for each graph.
</span>f(x) = 4x - 3 = y
y = 4x - 3
<span>for graph of line S we have the coordinates (0, -3) and (2, 5)
</span>(0, -3)
-3 = 4(0) - 3
-3 = -3
(2,5)
5 = 4(2) - 3
5 = 8 - 3
5 = 5
So the answer is the graph of line S.
