First question: y = -2x - 1.
Second Question: y = -4x + 3
Third Question: y = -3x - 5
The work for the first problem is shown in the attachment. The 2nd and 3rd problems use different numbers.
Simplification of the expression gives 2a + c = -24
<h3>How to simplify the equation</h3>
4+4-3-4-2-5-1-8-9-0=a +c + a
First, let's add

Then, let's substract

<em />
We then have,

Thus, simplification of the expression gives 2a + c = -24

5y=95
y=95/5(vertically opppsite angles)
5x=85
x=85/ 5(vertically opppsite angles)
C I think because if you multiply 5 to everything you would get c
So basically 3cm is the model and 2 m is the actual size. So the hood is 1m so it is half of 2m which means the answer to the question is 1.5cm
