The coordinates for point R will be (-1, -6). This is because a rectangle has opposite sides and as you plot your rectangle with these defines points along with that of R, you will be able to successfully achieve a perfect rectangle.
(x-3.2, y+1) . Y'=(4.3, 6) Z'=(4.8, 5)
The preimage (6,-2.3) differs from the image (2.8,-1.3) by subtracting the coordinates of the pre-image from the image leaving a -3.2 difference for x and a +1 for the y value. apply this rule to Y and Z to get Y' and Z'.
Answer:
a: 
b: 5
c: 8
Step-by-step explanation:
<em>Explanation for a: Making the equations</em>
Assuming h is the amount of half-page ads and f is the amount of full page ads, we can create the equations since the total cost will be 800$, and we have a total of 13 ads.
<em>Explanation for b: Solving for h</em>
We can now solve for one of the variables using elimination. Let’s multiply the expression 
by -75.
Great! Now let’s add the equations.
Adding these equations, we get
Divide both sides by -35, and we get 
.
<em>Explanation for c: Solving for f</em>
We can now substitute h inside the equation 
.
Hope this helped!
To simplify this expression, you have to distribute. Distribution is when you multiply the outside number by the inside ones. For example, if I distributed 2(4 + 6), I would get (2 × 4) + (2 × 6).
So if we distribute your expression, we'd get:
(-3 × -4y) + (-3 × 3) + 7y
Now simplify:
12y + -9 + 7y
Once more, simplify:
19y - 9
The answer is A
