Answer:
see explanation
Step-by-step explanation:
Under a reflection in the x- axis
a point (x, y ) → (x, - y ), hence
F(- 1, 9) → F'(- 1, - 9)
G(- 2, 1) → G'(- 2, - 1)
H(- 7, 4) → H'(- 7, - 4)
Answer:
solution set={18,10}
Step-by-step explanation:
x²-8x-180
comparing the above equation with the standard quadratic ax²+bx+c=0 equation,we get
here a=1 and b=-8 and c=-180
the quadratic formula is
x=-b±√(b)²-4ac/2a
putting values in the quadratic equation
x=-(-8)±√(-8)²-4(1)(-180)/2(1)
x=8±√64+720/2
x=8±√784/2
either
x=8+√784/2 or x=8-√784/2
x=8+28/2 or x=8-28/2
x=36/2 or x=-20/2
x=18 or x=-10
solution set = {18,-10}
i hope it will help you
Answer:
a. 7
b. 2
Step-by-step explanation:
a. By the secant secant theorem, 5 ( x+5) = 6 (4+6)
5x + 5 = 60
5x = 35
x =7
b. 4(x+4) = 3 (3 + 5)
4x + 16 = 24
4x = 8
x = 2

Answer:
$3.25 is her change.
Step-by-step explanation:
$10.00 - $6.75 is $3.25, her change.
The length of side RQ in triangle PQR is 7.5.
Given,
ΔJKL ≈ ΔPQR
Therefore, sides are in same ratio to each other i.e.
Therefore,
5 = t/1.5
t = 5*1.5
t = 7.5
Hence, length of RQ is 7.5.
Correct question,
Triangle JKL is similar to triangle PQR, find t. The sides of JKL measures
sJL = 4.5 sLK = 1.5 sJK = 5. The sides of PQR measures sQP = 25 sRP = 22.5 and sRQ = t. Find the length of RQ.
