Answer:
Step-by-step explanation:
Adding both equations
4x+5y+5y-4x=19+38
10y = 57
y= 5.7
Subtracting equation i from ii
5y-4x-4x-5y=38-19
-8x=9
x= -0.9
Answer:
15, 225,3375,50625,759375
Answer:
(4, -1) (3, 5) In this problem, we use the formula y2 - y1 over x2 - x1.
Step-by-step explanation:
Step 1: Plug In--> <u>5 - (-1)</u>
3 - 4
Step 2: Simplify. --> <u>6</u>
-1
Answer: <u><em>-6</em></u>
Answer: Step 4
Step-by-step explanation:
The absolute value of 21 is 21, not -21,
9+2 = 11 8+3 = 11are you going to do is just add in that's all it does
