The original price of the coat is $90
F(x) = x² + 2x - 1
f(2) = 2² + 2 · 2 - 1 = 4 + 4 - 1 = 7
f(-2) = (-2)² + 2 · (-2) - 1 = 4 - 4 - 1 = -1
f(3) = 3² + 2 · 3 - 1 = 9 + 6 - 1 = 14
f(-3) = (-3)² + 2 · (-3) - 1 = 9 - 6 - 1 = 2
The range = {-1; 2; 7; 14}
Answer:
The perimeter will be 10 times the original.
Step-by-step explanation:
Formula for Perimeter of rectangle is
2l + 2 w. From the diagram shown, the perimeter is 2×6 +2×3 = 12+6 =18cm
If if each side is increased by a factor of 10
Our length becomes 6×10= 60cm
Our width becomes 3×10= 30cm
New perimeter becomes
2×60 + 2×30
= 120+60 = 180cm
New perimeter(180 cm)= 10× original perimeter (18cm)
So The perimeter will be 10 times the original.
Answer:
x = 4
m<cdb = 82
Step-by-step explanation:
The exterior angle thm states that the exterior angle of a triangle is equal to the sum of the opposite interior angles:
7x + 2 + 17x = 98
24x + 2 = 98
24x = 96
x = 4
m<cdb =
y + 98 = 180
y = 180 - 98
y = 82
