Answer:
97.425
Step-by-step explanation:
C▲RST/C▲XYZ=1/3
S▲RST/S▲XYZ=1/9
The area of ▲RST is 10.825
SO the are of ▲XYZ is 10.825*9=97.425
Point H -3 1/2 should be the answer
Answer:
C(4, 6) => dilated by a factor of 1/3 => C'( 3x2/3, 6x2/3) = C'(2, 4)
Answer:
4th option
Step-by-step explanation:
x² - 2x - 3 = 0 ( add 3 to both sides )
x² - 2x = 3
using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 1)x + 1 = 3 + 1
(x - 1)² = 4
Since we have (4,?) we know x=4. Substitute this into the equation and solve for y.
y= 2/7*4+3
y= 2/7*4/1+3
y= 8/7+3
y= 8/7 + 3/1
y= 16/14 + 42/14
y= 58/14 or 4.14
