Answer:
Step-by-step explanation:
2.
y=kx
8=-4k
k=-2
so y=-2x
3.

4.
eq. of line is y-5=4(x+2)
Answer:
D
Step-by-step explanation:
Lengths:
WX: 2
XY: 2
WY: sqrt[(4-2)² + (2-4)²]
sqrt(4+4)
4sqrt(2)
W'(8, 16), X'(8, 8), Y'(16, 8)
W'X': 8 --> 4 × 2
X'Y': 8 --> 4 × 2
W'Y': sqrt[(16-8)² + (8-16)²]
sqrt(64 + 64)
8sqrt(2) --> 4 × 2sqrt(2)
D is a dilation with factor 4
The answer is 207 or 2 hundreds 7 ones in unit form or two hundred seven in word form.

The key problem is working out the value of 90,000 divide by 10. This is a division operation.

Option-1
Both numbers are divided by 10.

The result is

Option-2
Division operations can be written as fractions, like this.

The numerator and denominator are both divided by 10, or 'cross out a zero from both'.

The result is

- - - - - - -
If x is divided by y equals z, then x is equal to y multiplied by z.

Let's prove it!

This is proven.
