Hey there! :)
Answer:
y = 11.
Step-by-step explanation:
Set both of the equations equal:
5x - 9 = x² - 3x + 7
Rearrange the equation:
0 = x² - 3x - 5x + 9 + 7
Combine like terms:
0 = x² - 8x + 16
Factor:
0 = (x -4)²
Solve for x:
0 = x - 4
x = 4.
Plug this into an equation to solve for 'y':
y = 5(4) - 9
y = 20 - 9
y = 11.
Answer:
98.42
Step-by-step explanation:
7 × 14.6 =
= 7 × (7 + 7 + 0.6)
= 7 × 7 + 7 × 7 + 7 × 0.6
= 49 + 49 = 0.42
= 98.42
