X + y = 138
x - y = 88
--------------------------
x + y = 138
-x
y = -x + 138
--------------------------
-> substitute " -x + 138" into y
x- (-x+138) = 88
x + x - 138 = 88
2x - 138 = 88
+ 138
2x = 226
2x/2 = 226/2
x= 113
---------------------------
-> substitute "113" into x to get y
113 - y = 88
-113 -113
-y= -25
y = 25
---------------------------
Our final answers are the two numbers "113" and "25"
Based on what is written, Patty's Pies used 5 cups of peaches per 1 peach pie. As you can see, for every 1 pie in each example, 5 cups of peaches are used, 10 cups for 2 pies, 15 cups for 3 pies, etc. For 9 pies, multiply 5*9 to get 45. They would use 45 cups of peaches to make 9 pies if they continued to follow the same pattern.
I hope this helps :)
Answer:
y-(x+1)^2-3
Step-by-step explanation:
a=0
b=-3
you would only change a from 0 if you need to change the slope of the graph.
If the co-vertices are (0, 3) and (0, -3) where x is 0 and y has a value, then y is the minor axis. That means that the x axis is the major axis. Because of what the co-vertices are, the center of the ellipse is at the origin. The formula for an ellipse that has a horizontal major axis is
. The a value will always be larger than the b value, therefore, the a value goes under the coordinate that is the major axis. Here, its the x-axis. a is the distance that the outer edge of the ellipse is from the center. It's 8 units away from the center along the x axis and 3 units along the y axis from the center. So a = 8 and a^2 = 64; b = 3 and b^2 = 9. Our formula then is
Answer:
4.4 miles
Step-by-step explanation:
2.7 + 3.6 + 4.3 = 10.6
Subtract 10.6 from 15 to get your answer
15 - 10.6 = 4.4 miles
