Answer:
The cost of a shirt is $16 and the cost of a sweater is $33
Step-by-step explanation:
Let
x -----> the cost of a shirt
y -----> the cost of a sweater
we know that
-----> equation A
----> equation B
Solve the system by graphing
Remember that the solution of the system is the intersection point both graphs
The solution is the point (16,33)
see the attached figure
therefore
The cost of a shirt is $16 and the cost of a sweater is $33
The expression evaluates to 20
We have : 5 |3-7|
We have to evaluate above expression.
<h3>State the property Modulus of the function - F(x) = x.</h3>For a function f(x) = x, which is real in nature -
f(x) = |x| =
The above property is called Modulus property. It is used to find the absolute value or magnitude of a quantity.
In the question it is given -
5 |3-4|
5 |3 - 4|
5 x 4 = 20 {Using the property of modulus f(x) = - x for x < 0}
Hence, the expression evaluates to give an absolute value of 20
