Answer: (-x,y)
Step-by-Step Explanation:
In geometry, when a figure is reflected over particularly the y-axis, one coordinate will change.
The y coordinate will remain the same, not value wise. (positive in your case.)
Wherease the x coordinate will be the opposite additive inverse.
For example if you have (4,3) and it is reflected over the y-axis, the new coordinate will be (-4,y)
Hope this helps! :)
Answer: x = 101.75
Step-by-step explanation:
Hi, to answer this question we have to solve the equation give, by isolating x:
8x-4 = 810
The first step is to Add 4 on both sides:
8x-4+4 = 810+4
8x = 814
Then we have to divide both sides by 8:
8x/8 = 814/8
Finally, the solution is:
x = 101.75

Answer:
3) x = 15; 95 and 85 4) x = 12; 98 for both angles
Step-by-step explanation:
2x + 65 + 3x + 40 = 180 Set the equations equal to 180
5x + 105 = 180 Combine like terms
- 105 - 105 Subtract 105 from both sides
5x = 75 Divide both sides by 5
x = 15
Plug 15 into both equations
2(15) + 65 = 95
3(15) + 40 = 85
4) 5x + 38 = 9x - 10 Set the equations equal to each other
- 5x - 5x Subtract 5x from both sides
38 = 4x - 10
+ 10 + 10 Add 10 to both sides
48 = 4x Divide both sides by 4
12 = x
Plug 12 into both equations
5(12) + 38 = 98
9(12) - 10 = 98
Answer:
115x-12x
Step-by-step explanation:
3(9-X) x 4+7
12(9-X)+7
108-12x +7
115-12x
