Aislinn bought a new car. After 8 months, the odometer read 14,010 miles. How many miles did
UNO [17]

d) Aislinn's average per month on her car is 1,751 miles per month.

<h3>How to find the average speed?</h3>

The average speed is calculated by dividing the total distance traveled by the total time it took to travel that distance. Speed is the rate at which something moves at any given time.

Average speed is the average rate of speed over the course of a journey. Velocity exists as the directional speed of a moving object as an indication of its rate of change in position as observed from a specific frame of reference and measured by a specific time standard.

Given,

After 8 months, the odometer read 14,010 miles.

Solution:

t = 8,

d =  14,010 miles,

s = ?

s = d/t

s =  14,010/8

s = 1751 miles/month.

Aislinn drove an average of 1,751 miles per month.

If x-2 is one of the factors of x^4-kx^2+4, find the value of k.
Andrei [34K]

Step-by-step explanation:

Given expression is x⁴-kx²+4 =0

x−2 is a factor of the given expression.

So, x=2

Substitute in the equation, we get

2⁴-k(2)²+4

⇒16+4k+4=0

⇒4k=−20

⇒k=−5

0.3x=15<br> Identify the slope and y-intercept.
masha68 [24]

Steps to solve:

0.3x = 15

~Divide 0.3 to both sides

0.3x/0.3 = 15/0.3

~Simplify

x = 50

This is a vertical line so the slope is undefined.

The line passes through the point (50, 0) and there is no y-intercept since its a straight vertical line.

Best of Luck!

2.<br>Remove the brackets and simplify <br>a) (x + 1) + (x + 2)?​
devlian [24]

Step-by-step explanation:

✲ \text{(x + 1) + (x + 2)}

Remove the unnecessary brackets :

⇢ \text{x + 1 + x + 2}

Combine like terms. Like terms are those which have the same base. Only coefficients of like terms can be added or subtracted.

⇢ \text{x + x + 1 + 2}

⇢ \text{2x + 3}

\red{ \boxed{ \boxed{ \text{Our \: final \: answer :  \boxed{ \underline{  \tt{2x + 3}}}}}}}

Hope I helped ! ♡

Have a wonderful day / night ! ツ
