4x - 2y = 14
y = 0.5x -1
Get just one variable on one side for both equations.
4x - 2y = 14 ⇒ 4x = 2y + 14 ⇒ 4x - 14 = 2y
y = 0.5x - 1 ⇒ x - 2 = 2y
Use the transitive property and then solve for x.
x-2 = 4x-14
12 = 3x
x = 4

You need to know what she needs for the recipe, assuming that's 1/3 she can make C, 15 batches
The full installment price is $ 2200, and the annual interest rate is 10%.
Since Clare wants to buy a used wide-screen TV that sells for $ 2,000 cash, and she will make a down payment of $ 1,000 and then six monthly payments of $ 200, to determine what is the full installment price and the annual interest rate is due perform the following calculation:
- 1000 + 200 x 6 = 1000 + 1200 = 2200
- 1000 = 100
- 1200 = 120
- 20/12 x 6 = 10
Therefore, the full installment price is $ 2200, and the annual interest rate is 10%.

I can’t tell what those options are.
The domain is the input values of a function, therefore the x values.
In this case the interval for the domain is
-4< x <= 4
Answer:
Step-by-step explanation:
we know that
The solution of the linear system of equations is the intersection point both graphs
using a graphing tool
we have
------> equation A
------> equation B
To find the solution equate the equation A and equation B
Solve for x
Find the value of y
------>
the solution is the point
