Sonia represented by x. Sophia represented by x+15. x+x+15 = 63
2x + 15 =;63
2x = 48
x =;24. Sonia
x+15 = 39. Sophia
Answer:
(x,y) across the y axis is (-x,y)
Step-by-step explanation:
When reflected across the y-axis, the x coordinate in the opposite.
Sub in -7 for x to get 2(-7)+8 which is -14+8=-6. f(-7)= -6
Answer:
Step-by-step explanation:
Without a second equation relating x and y, we can solve 3x - 1/2y = 2 ONLY for x in terms of y or for y in terms of x:
x in terms of y: Multiply all three terms of 3x - 1/2y = 2 by 2, to eliminate the fraction: 6x - y = 4. Now add y to both sides to isolate 6x: 6x = 4 + y.
Last, divide both sides by 6 to isolate x:
x = (4 + y)/6
y in terms of x:
y = 6x - 4
If you want a numerical solution, please provide another equation in x and y and solve the resulting system.
