Answer:

Equation 1: y = 2x + 7

Step-by-step explanation:

In general the equation of a straight line is:

y=mx+c where m is the slope of the line and c is the y intercept

Or we can say that a graph is a straight line if it is a linear function.

Equation 1: y = 2x + 7

It is a linear function hence, its graph is a straight line

Equation 2: y² = x − 1

 It is not a linear function hence, its graph is not a straight line

Equation 3: y = 2x² + 4

 It is not a linear function hence, its graph is not a straight line

Equation 4: y = 3x³

It is not a linear function hence, its graph is not a straight line

Hence, The equation whose graph is a straight line is:

Equation 1: y = 2x + 7

Since 2003 median home prices in Midvale, UT have been growing exponentially at roughly 4.7 % per year. If you had purchased a h
Kipish [7]

Answer:

The home would be worth $249000 during the year of 2012.

Step-by-step explanation:

The price of the home in t years after 2004 can be modeled by the following equation:

P(t) = P(0)(1+r)^{t}

In which P(0) is the price of the house in 2004 and r is the growth rate.

Since 2003 median home prices in Midvale, UT have been growing exponentially at roughly 4.7 % per year.

This means that r = 0.047

$172000 in 2004

This means that P(0) = 172000

What year would the home be worth $ 249000 ?

t years after 2004.

t is found when P(t) = 249000. So

P(t) = P(0)(1+r)^{t}

249000 = 172000(1.047)^{t}

(1.047)^{t} = \frac{249000}{172000}

\log{(1.047)^{t}} = \log{\frac{249000}{172000}}

t\log(1.047) = \log{\frac{249000}{172000}}

t = \frac{\log{\frac{249000}{172000}}}{\log(1.047)}

t = 8.05

2004 + 8.05 = 2012

The home would be worth $249000 during the year of 2012.

Classify the triangle. Select all that apply
dlinn [17]
One of the answers is equilateral because all of the sides are of equal length. 
The other answer is acute because all of the angles are under 90º since they are all 60º. Hope this helps!

The weight of a specific type of male monkey is normally distributed with a mean of 15 pounds and a standard deviation of 3 poun
Viktor [21]

Answer:

1.33

Step-by-step explanation:

The z-score of a value is found by subtracting the mean from the value and then dividing by the standard deviation, this is the formula for the z-score.

z-score = (19-15)/3

z-score = 4/3

z-score = 1.33

The z-score for the monkey is about 1.33

Why does it help to rearrange
hichkok12 [17]

Answer:

You don't really need to do it, but it helps you keep things more organized and easier to follow. Imagine if you're doing some multi-variable equation,

2a + 5b + 4d + 3c + b + a + 2d

that looks like a mess, it'll be easier to look at if you put all the similar variables next to each others like this:

a + 2a + b + 5b + 3c + 2d + 4d

(a + 2a) + (b + 5b) + 3c + (2d + 4d)

now you can add them up much easier.
