Answer:
<h2> f(-7) = 249 </h2>
Step-by-step explanation:
To find f(-7) , substitute the value of x that's - 7 into f(x). That is for every x in f(x) replace it with - 7
We have
We have the final answer as
<h3>f( -7) = 249</h3>

Answer: 2 enlargments
Step-by-step explanation:
Use proportion for each enlargment you do
Side a=6cm Side b=4cm
6:4=x:7 4:4=b1:7
7*6=4a1 b1=28/4
a1=42/4 b1=7 after first enlrge
a1=10.5 after first enlarge 7:4=b2:7
10.5:4=a2:7 b2=49/4
a2=73.5/4 xb2=12.5 after 2nd enlarge
a2=18.375 after 2nd enlarge
12.5:4=b3:7
18,375:4=a3:7 b3=21.875 cm after 3rd enlargement
a3=32.15after 3rd enlargement
Values after 3rd enlargement are higher than dimension given for picture wall
30 cm by 20 cm
Point slope form : y-y₁=m(x-x₁)
Goes through (-3, -7) and the slope = -6/5
Since we are given the slope and the x₁ as well as y₁, we can simply plug everything into the point slope formula.
y - (-7) = -6/5(x - (-3))
Simplify.
y + 7 = -6/5(x + 3)
