4. C and D both are correct
12. H
11. B
The first person might be right
The answer is 3.50
Because 15-7 equal 8,6 times 0.75 equal 4.50, and 8-4.5 equal 3.50
The domain is the possible input values "x" .. in this case [-4, -2, 0, 2, 4]
The range are the possible output values of f(x)
We need to solve f(x) = 3.2x for each value in our domain
f(-4) = 3.2(-4) = -12.8
f(-2) = 3.2(-2) = -6.4
f(0) = 3.2(0) = 0
f(2) = 3.2(2) = 6.4
f(4) = 3.2(4) = 12.8
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.
