On the complex plane, the real component of a complex number is graphed along the horizontal axis while the imaginary component is graphed along the vertical axis.
Positive numbers go to the right on the real axis and up on the imaginary axis, and vice versa for negative numbers.
Therefore, the number -14-5i is in the 3rd quadrant because it graphed to the left of the origin and down.

The inputs are 1 and -1 when the output is 2.
Step-by-step explanation:
The given function is
f(x) = 10 x²
Then we set y = f (x)
y = 10 x²
By dividing each side by 10 we get
x² = y/10
Then we solve for x
x = ±
Now we have to find the input(s) when the output is 10
x = ±
x = ± 1
Hence, the inputs are 1 and -1 when the output is 2.
The final solution is x =1 and x = -1.
Claim: The measures of
and
are equal
Answer: True
Explanation: Dilations preserve the shape of an image, so this means the angles are kept the same whether you shrink or enlarge the preimage.

Claim: The coordinates of A and A' are the same
Answer: True
Explanation: The phrasing "dilating about point A" means that point A is the center of the universe, so to speak, in terms of this dilation operation. Point A is the fixed point that does not move while every other point does move. Because the scale factor is 2/3, which is less than 1, this means every other point comes closer to point A. So something like segment AB will get shorter.

Shop A _________________ shop B £3
Any sandwich - £2.85 ___ sandwich, water crisp
A bottle of water - 60p
A bag of crisp - 85p
Answer:
£6.50, John is incorrect
Step-by-step explanation:
Number of working days = 5 = number of days meal is purchased
Total cost per meal, shop A :
£(2.85 + 0.60 + 0.85) = £4.3
Total cost for the week = 4.3 * 5 = £21.50
Total cost per meal cost Shop B = £3
Total cost for the week = 3 * 5 = £15
Difference :
£21.50 - £15 = £6.50
Hence, Amount John saves by buying from shop B is £6.50
