Line L has equation y = 4x - 7, and line M is parallel to line L and passes through the point (2, 15). Determine the equation of
Artist 52 [7]

Answer:

A: y = 4x + 7

Step-by-step explanation:

Step 1:  Our line is parallel to this line, so it has the same slope, but a different  y-intercept, so set up the equation...

  y = 4x + b      

We are given a  point (x, y) of (2, 15), so plug that in and solve for b.  

 15 = 4(2) + b

    15 = 8 + b      (simplify)

        7 = b      (subtract 8 from both sides to isolate b)

So the equation of our line is  y = 4x + 7

How to solve the function 4y+x=12
Sidana [21]
First you rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation

Second you solve it by using the formula of a straight line drawn on Cartesian coordinate system in which “y” is the vet risk axis and “x” the horizontal axis.

Tim looks up at the top of a tree at an angle of elevation of 40 degrees. If heis 5 ft tall and 10 ft from the tree, how tall is
dolphi86 [110]
<h2>Answer:</h2>

13.391 ft

<h2>Explanations:</h2>

The schematic diagram of the given question is shown below;

The height of the tree is expressed as:

H = h +5

Determine the value of h using the SOH CAH TOA identity

\begin{gathered} tan\theta=\frac{opposite}{adjacent} \\ tan40^0=\frac{h}{10} \\ h=10tan40 \\ h=10(0.8391) \\ h=8.391ft \\  \end{gathered}

Determine the height of the tree

\begin{gathered} H=h+5 \\ H=8.391+5 \\ H=13.391ft \end{gathered}

Hence the height of the tree is 13.391ft

Fruit punch juices boxes cost $0.35 per ounce , they come in boxes that are 8.5 ounces and 12.2 ounces each .
Archy [21]
If $0.35=1 ounce
          ?=8.5 ounces
8.5/1*$0.35=$2.975 Therefore 8.5 ounces cost $2.975

If 1 ounce =$0.35
  12.2 ounces=?
12.2/1*$0.35=$4.27
Therefore 12.2 ounces cost $4.27
