Answer:
x>9
Step-by-step explanation:
-4x + 15 < -21
Subtract 15 from each side
-4x + 15-15 < -21-15
-4x < -36
Divide each side by -4, remembering to flip the inequality
-4x/-4> -36/-4
x >9
Answer: 
Step-by-step explanation:
There are some transformations for a function
. Two of those transformations are:
1. If
, then the function is translated "k" units up.
2. If
, then the function is translated "k" units down.
In this case, you have the following Quadratic function
given in the exercise:

According to the information given, the function
is obtained by translating the Quadratic function
3 units up. Based on this, you can identify that the transformation is the following:

Where 
Therefore, you can determine that:

<h3>How to Interpret the Equation of a Linear Graph?</h3>
A linear graph can be modelled by an equation in slope-intercept form, as: y = mx + b. Here, we have:
- m as the slope value = change in y / change in x
- b as the y-intercept which is the point on the y-axis that the line intercepts which is also the starting value/initial value.
Given the linear equation, y = 5x + 10, it means the slope of the graph that represents this equation would be 5, while the line that intersects the y-axis would be at 10.
In the graph attached below, the slope is 5, and the y-intercept is 10.
Therefore, the graph that represents the linear equation is attached below.
