2n+9+5n=30 combine like terms on left side
7n+9=30 subtract 9 from both sides
7n=21 divide both sides by 7
n=3
A similarity transformation is one or more rigid transformations (reflection, rotation, translation) followed by a dilation. When a figure is transformed by a similarity transformation, an image is created that is similar to the original figure. In other words, two figures are similar if a similarity transformation will carry the first figure to the second figure.
5z>15-----subtract 2 on both sides
z>3----divide by 5
therefore, z must equal -10, or -4
The interpretation of y = 9.5x is that: (a) For each 1 minute, the runner ran 9.5 miles.
<h3>How to interpret the equation?</h3>
The equation of the line of best fit is given as:
y = 9.5x
Divide both sides by x
9.5 = y/x
From the question, we have:
- x ⇒ number of miles run
- y ⇒ time
This means that:
9.5 = number of miles run/time
Hence, the interpretation of y = 9.5x is that: (a) For each 1 minute, the runner ran 9.5 miles.
