Answer:

\huge\boxed{\sf f(3)=20}

Step-by-step explanation:

<u>Given function is:</u>

f(x) =3x^2-4x+5

Put x = 3

f(3) =3(3)^2-4(3)+5\\\\f(3)=3(9)-12+5\\\\f(3)=27-12+5\\\\f(3)=15+5\\\\f(3)=20\\\\\rule[225]{225}{2}

Help help help help please business
Margaret [11]

Answer:

x = 35°

Step-by-step explanation:

These are corresponding angles. When a transversal crosses 2 parallel lines, 4 angles are created at each intersection, and each pair of corresponding angles between those are congruent.

These angles are congruent, so you can set them equal to each other:

2x+20=3x-15

Then, just solve for x:

20=x-15\\35=x\\x=35

You can check that by plugging it back into both:

2x+20=3x-15\\2(35)+20=3(35)-15\\70+20=105-15\\90=90
