What is Carl’s constant rate of speed (in miles per hour)? 12 mph

How many miles will Carl have traveled after 2 hours? 24 Miles.

What is the slope of this line? -4

What is the value of  y when x = 3? y = 22

What is the rate (in dollars per ticket)? 15/1 | $15 per ticket

How much money will the theater earn if it sells 150 tickets? $2250

What does the point (30, 60) mean? (Hint: What is being graphed on the x-axis? What is being graphed on the y-axis?) (30,60) is equal to x=30 and y=60.

If Karen uses her cell phone for less than 30 hours a month, which company should Karen choose? Why?

I think that Karen should use Company K because if she uses Company J, there would already be an extra fee of $30 from the monthly payment. Instead, Company K doesn’t have the monthly payment plan, but the hourly price is two times pricier but cheaper. To make it simple, let’s say Karen use her phone for about 25 hours for the whole month.

Company J: $30 + $25(1) = $55

Company K: 25(2) = $50

Hurrrryyyyy plllzzz. Determine the equation of the line that passes through the given points

pashok25 [27]

<h2>Answer:</h2>

y = 2

<h2>Step-by-step explanation:</h2>

To determine the equation of the line that passes through (10,2) and (-3,2), we need to determine the slope of the line. Then substitute the slope and any given point in point slope form to obtain the equation of the line.

<h3>Finding the Slope of the line:</h3>

$\implies \text{Slope} = \dfrac{\text{Rise}}{\text{Run}} = \dfrac{y_{2} - y_{1} }{x_{2} - x_{1} }$

$\implies \text{Slope} = \dfrac{y_{2} - y_{1} }{x_{2} - x_{1} }$

Substitute the coordinates of the given points:

$\implies \text{Slope} = \dfrac{2 - 2}{-3 - 10 }$

Simplify the equation to determine the slope:

$\implies \text{Slope} = \dfrac{0}{-3 - 10 }$

∴ 0 divided by ANY number is ALWAYS 0.

$\implies \text{Slope} =0$

<h3>Finding the equation of the line:</h3>

Point slope form formula: y - y₁ = m(x - x₁)

x₁ and y₁ are the coordinates of any given point.
m is the slope

Substitute the values in the point slope form:

$\implies \text{Equation of line:} \ y - y_{1} = m(x - x_{1} )$

$\implies \text{Equation of line:} \ y - 2 = 0(x - 10)$

Simplify the equation to determine the equation of the line:

∴ Any number multiplied by 0 is 0.

$\implies \text{Equation of line:} \ y - 2 = 0$

$\implies \text{Equation of line:} \ y = 0 + 2$

$\implies \text{Equation of line:} \ y = 2$

Thus, the equation of the line is y = 2.

Can two vertical angles form a linear pair?

weqwewe [10]

Adjacent Angles are two angles that share a common vertex, a common side, and no common interior points. (They share a vertex and side, but do not overlap.) A Linear Pair is two adjacentangles whose non-common sides form opposite rays. ... ∠1 and ∠3 are not vertical angles (they are a linear pair).
