Answer:

Some calculators also display the ' × 10 ' part of the number, but not all do. You need to find out what your calculator displays. Remember, you must always write the ' × 10 ' part when you are asked to give an answer in standard form.

80% of Vanessa's final grade is based on the average score of her quizzes, which is 73.
Misha Larkins [42]
80% of quizzes + 20% of final = final grade

80% * 73 + 20% * x = 70

0.8 * 73 + 0.2x = 70

58.4 + 0.2x = 70

0.2x = 11.6

x = 58

Which method is most efficient in solving a system of linear equations when two equations have x values with opposite coiffiecen
bulgar [2K]

Answer:

Elimination

Step-by-step explanation:

A system of equations is 2 or more equations for which the same x,y solution exists. We can solve the system in three ways: elimination, substitution, or graphing. Elimination is the best method when we have standard form equations and x values with opposite coefficients. This is so because the x variable will eliminate easily and allow us to solve for y.

Someone help please thank you

Answer:

See below.

Step-by-step explanation:

So we have the two functions:

f(x)=8x-5\text{ and } g(x)=9-2x

And we want to find:

(f\circ g)(x)\text{ and } (g\circ f)(x)

1)

Recall that:

(f\circ g)(x)

is the same as:

=f(g(x))

Thus, we can substitute g(x):

=f(9-2x)

And substitute that into f(x):

f(x)=8x-5\\f(9-2x)=8(9-2x)-5

Distribute:

=72-16x-5

Subtract and simplify:

=67-16x\\=-16x+67

Thus:

(f\circ g)(x)=-16x+67

2)

Similarly:

(g\circ f)(x)=g(f(x))

Substitute f(x):

g(f(x))=g(8x-5)

Substitute:

g(8x-5)=9-2(8x-5)

Distribute:

=9-16x+10

Simplify:

=-16x+19

Therefore:

(g\circ f)(x)=-16x+19
