Answer:
x=3, y=0.8
Step-by-step explanation:
8x+5y=28
4x+5y=16
Subtract the second simultaneous equation from the first.
You are left with: 4x=12
12/4=3
x=3
Substitute this back into one of the equations.
8(3)+5y=28
8*3=24
28-24=4
4=5y
4/5=0.8
y=0.8
One option for the answer would be -(9+9)
Answer:
D. 68 degrees
Step-by-step explanation:
Remember, the total degree of a triangle is 180 degrees, not 360 like a rectangle.
To solve, set up an equation.
Solve:
Subtract 44 from both sides
Divide both sides by 2
y=68

The coordinates of the point after the two reflections are (0.3,-7/10).
<h3>What is the reflection?</h3>
A reflection is a mapping from an isometric hyperplane with a set of fixed points acting as the reflection's axis or plane from a Euclidean space to itself. A figure's reflection creates its mirror image of that figure in the plane or axis of the reflection.
Given that, the point (-0.3, 7/10) is reflected over the y-axis and then over the x-axis respectively.
The coordinates of the point after the reflection in the y-axis are:
(0.3, 7/10)
Now, the coordinates of the point after the reflection in the x-axis are:
(0.3, -7/10)
Hence, the coordinates of the point after the two reflections are (0.3,-7/10).

Answer:
So, I know that we will have to find the Area of the "Shape" And I see a *Unlabeled/Unknown* Shape that we have to find the answer of/to.
Step-by-step explanation:
To find the volume, you multiply length times width times height, which is 3x1x2, which equals six. So the volume of the fish tank is 6 cubic feet. Volume is also how loud a sound is.
To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.
