Answer:
f(x)=(3x-5)(4x+2) is a quardatic function.
Step-by-step explanation:
f(x)=(3x-5)(4x+2)
simplify
f(x)=3x(4x+2)-5(4x+2)
f(x)=
adding the coefficients of x, we get
f(x)=
which is quardatic equation since it contains the terms 12

The height of the top of the mountain is 50.67 feet
<h3>The mirror</h3>
Jackson placing the mirror in front of him will result in relations that have equivalent ratios.
<h3>Equivalent ratios</h3>
So, the equivalent ratios are represented as:

Where x represents the height of the mountain
Cancel out the common units

Express as fractions

Make x the subject


Multiply

Convert the unit to feet



Hence, the height of the top of the mountain is 50.67 feet

Answer:
3x + y = -1
Step-by-step explanation:
y-5=-3( x+2)
once you distribute, you get y-5=-3x-6
then, add 5 to each side and get y=-3x-1 (this is slope intercept form)
finally, add 3x to each side to get 3x+y=-1 (standard form: Ax + By = C)
Answer:
3y + 2
Step-by-step explanation: add like terms
