X = -10
Y = 8
2 X + 3 Y = 4 ---- (i)
5 X + 4 Y + 13 = 0 ---- (ii)
rearranging eqn (ii), we have
5X + 4Y = -13 ----- (ii)
multiply eqn (i) by 5 and eqn (ii) by 2
10X + 15Y = 20 ---- (iii)
10X + 8Y = -26 ---- (iv)
subtracting eqn (iv) from (iii), we have
10X - 10X + 15Y - 8Y = 20 - (-26)
0 + 7Y = 20 + 26
7Y = 56
Y = 56/7
Y = 8
Substituting Y into eqn (i), we have
2X + 3Y = 4
2X + 3(8) = 4
2X + 24 = 4
2X = 4 - 24
2X = -20
X = -20/2
X = -10
Answer:
Literally 3 or next to 3 on the number line
Step-by-step explanation:
The square root of 9.2 is 3.03 or 3 if you wanna round to the nearest whole number. So that's what I mean by 3.03 being right beside 3 on a number line. to check my answer/reply yourself just go to Desmos number line and zoom in to three and beside it you will see 3.03. But you can also just plot three its kinda the same thing unless it has to be exact.
