We have that
y=x²----> equation 1<span>
y=x+2-----> equation 2
multiply equation 1 by -1
-y=-x</span>²
add equation 1 and equation 2
-y=-x²
y=x+2
------------
0=-x²+x+2-------------> -x²+x+2=0-----> x²-x-2=0
Group terms that contain the same variable, and move the
constant to the opposite side of the equation
(x²-x)=2
<span>Complete
the square. Remember to balance the equation by adding the same constants
to each side
</span>(x²-x+0.5²)=2+0.5²
Rewrite as perfect squares
(x-0.5)²=2+0.5²
(x-0.5)²=2.25-----> (x-0.5)=(+/-)√2.25-----> (x-0.5)=(+/-)1.5
x1=1.5+0.5-----> x1=2
x2=-1.5+0.5---- > x2=-1
for x=2
y=x²----> y=2²----> y=4
the point is (2,4)
for x=-1
y=x²----> y=(-1)²---> y=1
the point is (-1,1)
the answer isthe solution of the system are the points(2,4) and (-1,1)
Answer:
A square root parent function
Step-by-step explanation:
The greatest number of treats you can buy is 7 because you bought $18 worth of dog food, leaving $7 for treats.
The answer would be 1/8 because when 1/8 is divide into the endpoints of AB you will recieve 1/8 of the endpoint numbers. Like 1/8 of 4 would be written as 1/8 times 4/1 since its a fraction multiply 1 times 4 and 8 times 1 to get 4/8. 4 goes into 4 one time and into 8 2 times giving you 1/2. Hope this helped.

Answer: 13 days</h3>
====================================================
Explanation:
Count the number of leaves marked in green.
- Row One: 2 leaves (1 and 8)
- Row Two: 3 leaves (3, 6, and 9)
- Row Three: 5 leaves (2, 3, 4, 6, 7)
- Row Four: 3 leaves (1, 6, and 8)
There are 2+3+5+3 = 13 leaves total. This represents tickets were sold on 13 days.
Each stem and leaf combines to form a different ticket count. For instance, the stem of 1 and leaf of 8 combine to get the value 18. So 18 tickets were sold on that particular day.
