Answer:
Solution: x=5, y=4
Step-by-step explanation:
System of Equations
We need to solve:
- 5x + 9y = 11
x - 3y = - 7
There are several ways to solve a system of linear equations. We'll take advantage of the second equation since it has the x with coefficient 1 and solve it for x:
x = - 7 + 3y
Now replace it into the first equation:
- 5(- 7 + 3y) + 9y = 11
Operate:
35 - 15y + 9y = 11
Simplify:
35 - 6y = 11
Rearrange:
- 6y = 11 - 35 = -24
Solve:
y = -24 / -6
y = 4
Finally, since
x = - 7 + 3y
x = - 7 + 3*4
x = - 7 + 12
x = 5
Solution: x=5, y=4
B. Pyramid
C. Cone
D. Polygon
The Prism and Pyramid is a typical example of polyhedron. That is optionA and B.
A polyhedron is any solid that has a three dimensional shape with all its sides flat. It is made up of different polygons that join together.
These polyhedron are made up of three parts:
Examples of polyhedron are the Prism and Pyramid. The prisms have flat faces and is made up of rectangles while the pyramids is made up of triangles and different polygons.
Therefore, the Prism and Pyramid is a typical example of polyhedron.

Answer:
hey. pls complete your question.
Answer: The graph of the function is symmetric about the y-axis.
Explanation:
Symmetric about the y-axis means that the graph can be reflected over, in this case the y-axis, without altering it. Your function is able to do this! I’ve attached a picture of the function so that you can visualize what I wrote.

Answer:
G: Inverse multiplication
Step-by-step explanation:
Statement is 2•1/2=1
Now, what this means is that when we multiply a number by it's inverse form, the result will be 1.
This means that this statement denotes an inverse multiplication.
Thus, the last option is the correct answer
