Please help explanation if possible
stira [4]

Answer:

y = 2x + 7

Step-by-step explanation:

Use Point Slope Form since we are given the slope and coordinates. Why is the slope 2x?

<em> </em><em>In</em><em> </em><em>Depth</em><em>:</em><em> </em><em>Parallel lines never touch so</em><em> </em><em>they</em><em> </em><em>are</em><em> </em><em> Lines that have same slope but different y intercept</em><em>.</em><em> An example is a square. A square has four parallel sides. The upper and lower sides will never touch because they are the same slope and they both have a finite distance vertically between them. </em>

<em>Back</em><em> </em><em>to</em><em> </em><em>the</em><em> </em><em>question</em><em>,</em><em> </em><em>let</em><em> </em><em>use</em><em> </em><em>the</em><em> </em><em>Point</em><em> </em><em>S</em><em>lope</em><em> </em><em>Form</em><em>,</em>

<em>y -  y_{1} = m(x -  x_{1})</em>

<em>Where</em><em> </em><em>y1</em><em> </em><em>is</em><em> </em><em>the</em><em> </em><em>y</em><em> </em><em>coordinate</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>given</em><em> </em><em>point</em><em>,</em><em> </em><em>m</em><em> </em><em>is</em><em> </em><em>the</em><em> </em><em>slope</em><em> </em><em>and</em><em> </em><em> </em><em>x</em><em> </em><em>is</em><em> </em><em>the</em><em> </em><em>x</em><em> </em><em>coordinates</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>given</em><em> </em><em>points</em><em>.</em>

<em>Substitute</em><em> </em>

<em>y  - ( - 1) = 2(x - ( - 4)</em>

<em>y + 1 = 2(x + 4)</em>

<em>Simplify</em>

<em>y + 1 = 2x + 8</em>

<em>y = 2x + 7</em>

Find the value of Theta in these diagrams (a and b)​
ZanzabumX [31]

a. θ = 36. 9°

b. θ = 114. 2°

<h3>How to determine the value of theta</h3>

a. We use the cosine identity

cos θ = adjacent/hypotenuse

Adjacent = 4cm

Hypotenuse = 5cm

cos θ = 4/ 5

cos θ = 0. 8

Now, we have the inverse of the cosine value

θ = cos^-1 (0. 8)

θ = 36. 9°

b. We use the tangent identity

tan a = opposite / adjacent

tan a = 3. 8/1. 7

tan a = 2. 23

a = tan^-1 ( 2. 23)

a = 65. 8

We have;

a + θ = 180 °; angles on a straight line

θ = 180 - 65. 9

θ = 114. 2°
