Your answer is (0,-3). The axis of symmetry is basically the y part in a vertex. I just found the vertex of the equation (showed you the steps how to do so if you don’t know) and then took the y value of the vertex-which is the axis of symmetry. Hopes this helps!
Answer:
x = 144°
Step-by-step explanation:
In the figure given , two regular polygons are given to us. Since the polygon has five sides , it is a regular Pentagon. We know that each angle of a regular Pentagon is 108° .
So , here as per figure two regular Pentagons are attached base to base . Now , we know that,
- Measure of complete angle is 360° .
- Measure of regular polygon's angle is 108°.
According to Question ,
⇒ 108° + 108° + x = 360°
⇒ 216° + x = 360°
⇒ x = 360° - 216°
⇒ x = 144°

Answer:
C. 14 ft by 21 ft
Step-by-step explanation:
First you want to set up an equation:
3 1/2" over x' = 1/4" over 1'
7/2 = 1/4x
14' = x
Next, do the same thing for the other side of the drawing (5 1/4")
5 1/4" over y' = 1/4" over 1'
21/4 = 1/4y
21' = y
So the answer is 14 ft by 21 ft (C)
small frames ($8): s
large frames ($15): L
Cost: 8s + 15L = 239 ⇒ 1(8s + 15L = 239) ⇒ 8s + 15L = 239
Quantity: s + L = 22 ⇒ -8( s + L = 22) ⇒ <u> -8s -8 L = -176 </u>
7L = 63
L = 9
Quantity: s + L = 22 ⇒ s + (9) = 22 ⇒ s = 13
Answer: 13 small frames, 9 Large frames
25) It is a right triangle
3²+4²=5²
9+16=25
25=25
26) It is a right triangle
6²+8²=10²
36+64=100
100=100
27) Not a right triangle
5²+5²=10²
25+25=100
50=100
28) It is a right triangle
5²+12²=13²
25+144=169
169=169
Hope this helps :)
