I'll help because your pfp proves that you are indeed a classy individual

So.... using the <em>point-slope formula</em>

y-y₁=m(x-x₁)

y₁ is the y-coordinate

x₁ is x-coordinate

m is the slope

when we find the slope from both points we find that they both have a slope of 16/3

therefore... the lines are parallel

A line has a slope of 1 and passes through the point (14, 0). What is its equation in

SpyIntel [72]

Answer:

y = x - 14

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = 1, thus

y = x + c ← is the partial equation of the line

To find c substitute (14, 0) into the partial equation

0 = 14 + c ⇒ c = 0 - 14 = - 14

y = x - 14 ← equation in slope- intercept form

Boa drove from the Dead Sea up to Jerusalem and her altitude increased at a constant rate of 740 meters per hour. When she arriv

Alborosie

Answer:

$y=740x-400$

Step-by-step explanation:

The story tells us that Boa drove from the Dead Sea up to Jerusalem. With the data provided, we can assume a linear relationship between altitude and the number of hours. We are given two key data: one point and the rate of change (or slope).

We can easily find the equation of a line with slope m passing through a point (a,b) by using the formula

$y-b=m(x-a)$

In this case, y is the altitude above sea level, and x is the number of hours of driving

The value of m is 740 meters/hour and the known point is x=1.5 hours, y=710 meters. Using these values

$y-710=740(x-1.5)$

$y-710=740x-1110$

$y=740x-400$

The areas of two similar triangles are 20m2 and 180m2. The length of one of the sides of the second triangle is 12m. What is the

guajiro [1.7K]

Answer:

The corresponding side of the first triangle is 4 m.

Step-by-step explanation:

Area of the first triangle: A1=20 m^2

Area of the second triangle: A2=180 m^2

Lenght of one of the sides of the second triangle: s2=12 m

Corresponding side of the first triangle: s1=?

A1/A2=(s1/s2)^2

Replacing the known values:

(20 m^2)/(180 m^2)=[s1/(12 m)]^2

Simplifying:

2/18=[s1/(12 m)]^2

Simplifying the fraction on the left side of the equation dividing the numerator and denominator by 2:

(2/2)/(18/2)=[s1/(12 m)]^2

1/9=[s1/(12 m)]^2

Solving for s1: Square root both sides of the equation:

sqrt(1/9)=sqrt{[s1/(12 m)]^2}

sqrt(1)/sqrt(9)=s1/(12 m)

1/3=s1/(12 m)

Multiplying both sides of the equation by 12 m:

(12 m)*(1/3)=(12 m)*s1/(12 m)

Simplifying:

(12 m)/3=s1

4 m=s1

s1=4 m
