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
There r 2 ways to do this....percent to decimal
(1) u can divide by 100.....289/100 = 2.89
(2) u can move the decimal 2 spaces to the left....2.89
just so u know ... decimal to percent
(1) multiply by 100
(2) move decimal 2 spaces to right
True
using the converse of Pythagoras' identity
Given 3 sides of a triangle, if the longest side squared is equal to the sum of the squares of the other 2 sides then triangle is right.
longest side squared = 26² = 676
sum of other 2 sides squared = 24² + 10² = 576 + 100 = 676
Hence triangle is right
I only know this because I remember the common fractions, and 1/3 is .3333 repeating.
