Answer:
B. (2, 4)
Explanation:
<u>Given equations</u>:
a) y = x + 2
b) y = 3x – 2
Solve them simultaneously:
x + 2 = 3x – 2
x - 3x = -2 - 2
-2x = -4
x = 2
Then find y = x + 2 = 2 + 2 = 4
Solution: (x, y) = (2, 4)
Answer: 5
One half of 10 is 10/2 or 1/2(10)
10/2 = 5
1/2(10) = 5
2) 7/4×(22–x) =0
soln
= 7/4×(22 –x) =0
= 1.75 ×22 –x =0
= x=38.5
9) 15x² /7 =8x²/5
soln
= 15x²×8x²=7×5
=120x^4 = 35
= x^4 =120–35
x^4 =85
6) 9x²/4–4=0
soln
=9x²/4–4=0
=2.25–4=0
=4–2.25=0
=1.75
