We have that in this case the following equalities are met:
DH = HF
x + 3 = 3y
GH = HE
3x - 3 = 5y + 4
We then have the following system of equations:
x-3y = -3
3x-5y = 7
Resolving the system graphically we obtain the following values:
x = 9
y = 4
Note: see attached image.
Answer:
The values of x and y are:
x = 9, y = 4
For this case we have that a quadratic equation is of the form:
Where:
a: is the main coefficient because it accompanies the quadratic variable.
b: It is the linear coefficient
c: It is the constant term.
Then, a quadratic function with a main coefficient of "3" and a constant term of "-12" is:
Answer:
Option B
Ion know bro you tryna help me
Answer:
Step-by-step explanation:
y = -14, m = -2, b = -2
-14 = -2(x) + -2
-14 = -2x + -2
-12 = -2x
Divide by -2.
x = 6
On that specific day, the US dollar was worth more than the Canadian dollar and less than the Australian dollar.
<h3>Define the term comparison of numbers?</h3>
- In arithmetic, comparing numbers is described as the process or method of determining whether one number is smaller, bigger, or equal to some other number based on their values.
The equation u = 0. 99c depicts the value of the US dollar in relation to the Canadian dollar on a specific day.
- c = the Canadian dollar's value
- u denotes the value of the US dollar.
From the equation,
For Australian dollar; (from table)
u = 0.95 c -->
a = 1/0.95 u
a = 20/19 u
(20/19u - u)/ u = 1/19 ....1
For Canadian dollar:
u = 0. 99c
c = 1/0.99 u --> c = 100/99 u
Thus,
(100 u / 99 - u)/ u = 1/99 .....2
From 1 and 2]
1/19 > 1/99
Thus, on that specific day, the US dollar was worth more than the Canadian dollar and less than the Australian dollar.
