Answer:
The cost of one sandwich is $15 and the cost of one salad is $5
Step-by-step explanation:
<u><em>The question is</em></u>
Find out the cost of one sandwich and the cost of one salad
Let
x ----> the cost of one sandwich
y ---> the cost of one salad
we know that
-----> equation A
-----> equation B
Solve the system by graphing
The solution is the intersection point both graphs
using a graphing tool
the solution is the point (15,5)
see the attached figure
therefore
The cost of one sandwich is $15 and the cost of one salad is $5
Formula to find the area of a triangle = 
× base × height
For triangles A, B and D, the base occupies 4 squares and the height occupies 4 squares.
Therefore, area = × 4 × 4
= 2 × 4 = 8 sq. units
For triangle E, base occupies 2 squares and height occupies 8 squares.
Therefore, area = × 2 × 8
= 8 sq. units
For triangle C, base occupies 3 squares and height occupies 5 squares.
Therefore, area = × 3 × 5
= 7.5 sq. units
Hence, triangles whose area is 8 sq. units are A, B, D and E.
I dunno what your question ask
Answer:
(5,30)
Step-by-step explanation:
That is the constant change in the y's as the x's increase by 1?
12 - 6 = 6
18 - 12 = 6
24 - 18 = 6
The common difference is 6 so the next coordinate will be 6 more on the y and 1 more on the x.
(5,30)
The product is
-36x^6y-9xy^3+36x^3y-9xy^2
