Step-by-step explanation:
I did this for someone else and it took me a long time to explain, so here's the answers since this is timed.
F(89)=-12(89)-3=-1068-3=-1071
Blue Box: 6.03
Orange Box: -3
Equations
• x² + y = 0 ... (1)
• x² - 4x - y = 0 ... (2)
Answer -> (x, y) = (2, -4)
Step-by-step solution:
From equation 2,
-> y = x² - 4x ... (3)
• Substitute y into equation 1
-> x² + (x² - 4x) = 0
-> 2x² - 4x = 0
-> 2x² = 4x
-> x²/x = 4/2
-> x = 2
• Put x = 2 in equation 3
-> y = (2)² - 4(2)
-> y = 4 - 8
-> y = -4
Answer:
Formula for area of triangle:
A = bh x 1/2
Formula for area of parallelogram:
A = bh
Now find the area of the figure above which is a triangle:
3(base) x 8(height) x 1/2 = <em>12</em>
Let's find the area of the parallelogram;
6(height) x 9(base) = <em>54</em>
Add the two areas together:
12 + 54 = 66 cm2
