The expression y = 7 + 2x can be substituted into the first equation to find the variable "x"
<h3>System of equation</h3>
System of equation are made of two or more equations with unknowns
Given the system of equation
4x=5-2y
y-2x=7
From equation 2:
y = 7 + 2x
The expression y = 7 + 2x can be substituted into the first equation to find the variable "x"

You can find the area of a triangle by using this equation:
Area=(1/2)base x height
If you have the measurement for the bottom part of the sandwich, then you have your base. If you have the height of the sandwich then you have the height. Since the triangles are congruent when you find the area of one triangle, you are finding the area of the other triangle. To combine the areas of the triangles, just multiply the area of one triangle by 2.
The given function is
f(x) =
Comparing with
We get
a = 8, b = 2 & c = -5
Now if (h,k) is the vertex
then h =
Substituting the value of h in place of x in the function we get
k=
Now the vertex form of a quadratic equation is
f(x)= a(x-h)² + k
Substituting the values of a, h & k we get
f(x) = 8
The vertex form of f(x) = 8x² +2x-5 is
f(x) =
Answer
Answer:C) She would have $216.88.
Step-by-step explanation:
A) Deposits: +34.98; +51.02; +51.22
Withdrawals: -5.23; -5.22; -7.89
B) -7.89, -5.23, -5.22, +34.98, +51.02, +51.22
The smallest amount will be the largest withdrawal, as it takes away from the account; the largest amount will be the largest deposit, as it adds to the account.
98 + 34.98 = 132.98 + 51.02 = 184.00 + 51.22 = 235.22 - 7.89 = 227.33 - 5.23 = 222.10 - 5.22 = 216.88
