Keiko has scored 86, 91, 86, 61, and 87 on her previous five tests. what score does she need on her next test so that her averag

Andru [333]

X= grade on next test

Add up all scores, divide by 6 and this equals the average of 84

(86 + 91 + 86 + 61 + 87 + x)/6= 84
add in parentheses

(411 + x)/6= 84
multiply both sides by 6

411 + x= 504
subtract 411 from both sides

x= 93

ANSWER: 93 is needed on the next test to have an average of 84

Hope this helps! :)

At 2 hours before sunset, the temperature is 0°F. At 2 hours after sunset, the temperature is −4°F. Identify the equation repres

Yakvenalex [24]

For the given condition the equation represents the temperature y, in degrees Fahrenheit, at x hours after sunset will be y = -<u>4</u>x + <u>0.</u>

<h3>What is the equation?</h3>

An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.

It is given that, at 2 hours before sunset, the temperature is 0°F. 2 hours after sunset, the temperature is −4°F and the equation representing the temperature y, in degrees Fahrenheit, at x hours after sunset.

The equation is obtained as,

y = -4x + 0.

Thus, for the given condition the equation represents the temperature y, in degrees Fahrenheit, at x hours after sunset will be y = -<u>4</u>x + <u>0.</u>

If f(x) = 2x + 6 and g(x) = x, what is (gºf)(0)?

riadik2000 [5.3K]

Answer:

(gºf)(0) is 6

Step-by-step explanation:

It is a composition of functions problem, where

(gºf) = g(f(x)) is the composition of the functions g(x) and f(x). (gºf)(0) is the composition of the functions at the point x = 0. First, we find that function that is the g composite of x, then we replace x by 0.

g(4), for example, is g when x = 4, right? So g(4) = 4.

So,

g(f(x)) is going to represent g when x = f(x). x = f(x) when x = 2x + 6, so:

g(f(x)) = g(2x+6) = 2x + 6

We have that

g(f(x)) = gºf(x) = 2x + 6

Now, we just have to find the value of the function at x = 0. So

gºf(0) = 2(0) + 6 = 0 + 6 = 6.

(gºf)(0) is 6

The state withholding is 21% of the Federal withholding.
Since the state withholding was $122.25, the state withholding should be 0.21 x $122.25 = $25.67

Since $30.56 was withheld for state tax, then she must be thinking that the state withholding is too high, hence too much is being withheld.

Thus, option c is the correct answer.
