Answer:
Step-by-step explanation:
1). y = - 4x + 7
Reflected across what????
if x-axis, then y ⇒ - y
So the answer would be <em>y = 4x - 7</em>
2). <em>y = 2x - 14</em>
3). <em>y = 2x - 8</em>
4). <em>y = 12x + 9</em>
Answer:
Step-by-step explanation:
number of side = n =7
Sum of all the angles of given polygon = (n -2)*180 = 5 *180 = 900
x + 140 +133 +145 + 117 + 119 + 125 = 900
x + 779 = 900
x = 900 - 779
x = 121
Answer: 0.01402524544
Step-by-step explanation: When you divide 10 by 713 is 0.01402524544
Because both angles are the same, and are in the same spot in the congruent triangles, we can set these angles up to equal each other:

Add x to both sides:

Subtract 4 from both sides:

Divide both sides by 4 to get x by itself:

The value of x is
17.
