A reflection about the x axis, about y=0, is the mapping (x',y')=(x,-y) so

A dilation of 2 is the mapping (x'',y'')=(2x', 2y')
So




We can rewrite that without the primes and combine the powers of 2.

Let's graph these and see if we're close,
Plot y= (1/4)^x, y= - (1/4)^{x}, y = - 2^{1-x}
Answer:
24 yards, $77.40
Step-by-step explanation:
1) brown braid : 4*2.40 = $16.80
black lace : 7*2.40 = $29.40
gold ribbon : 13*2.40 = $31.20
2) 4 + 7 + 13 = 24 yards <
3) 16.80 + 29.40 + 31.20 = $77.40 <
Answer:
12y + 120
Step-by-step explanation:
<u>First of, what is the distributive property?</u>
The distributive property is the property that helps distribute numbers under the parenthesis.
For example, lets use {x+1}4. You distribute the 4 towards the x and the one like this:
4(x) + 1(4)
4x + 4
Now, let's go back to your problem
<u>Solution:</u>
{y+10}12
12(y) +12(10)
= 12y + 120
