Answer:

estimated gpa: 2.85

Step-by-step explanation:

Evaluate y=0.14x+0.75 at x = 15 (hours):

y = 0.14(15 hours) + 0.75

= 2.1 + 0.75

y = 2.85 = estimated gpa corresponding to 15 houirs of study

Y = x^2 - 64
x^2 - 64 = 0
x^2 = 64
x^2 = 8^2
x = 8 and x = -8

Kevin traveled at a constant speed on the highway from Hickory Hills to Chicago in 20 minutes. The distance from Hickory Hills t

beks73 [17]

Answer: $V=51\ \frac{mi}{h}$

Step-by-step explanation:

You need to used the following formula:

$V=\frac{d}{t}$

Where "V" is the speed, "d" is the distance and "t" is the time.

In this case you know that Kevin traveled at a constant speed on the highway from Hickory Hills to Chicago in 20 minutes (which is $\frac{1}{3}\ h$ ) and the distance is 17 miles. Then, you can identify that:

$t=\frac{1}{3}\ h\\\\d=17\ mi$

Therefore, knowing these values, you can substitute them into the formula. Then, you get:

$V=\frac{17\ mi}{\frac{1}{3}\ h}\\\\V=51\ \frac{mi}{h}$

If f(x)=3x^2+2 and g(x)=x^2-9 find (f-g)(x)

miss Akunina [59]

Here given, $f(x) = 3x^2+2$ and $g(x) = x^2-9$

we have to find $(f-g)(x)$ which means the subtracting of the functions f(x) and g(x).

$(f-g)(x) = f(x) - g(x)$

= $(3x^2+2) - (x^2-9)$

= $3x^2+2 -x^2-(-9)$

= $3x^2-x^2+2+9$ ( we know that multiplication of negative and negative is positive)

= $2x^2+2+9$

= $2x^2+11$

We have got the required answer here.

$(f-g)(x) = 2x^2+11$
