Answer:
7
Step-by-step explanation:
x * x = 7x
7 x 7 = 7 x 7
49 = 49
so if x is 7, the equation is true...
Answer: 75TT
(When you answer in terms of pi, don’t multiply pi but leave it in your answer)
Step-by-step explanation:
assuming the grain pile is a pyramid, V=1/3 TT r^2
(1/3) (TT) (15^2). Remember radius is 1/2 of diameter
(1/3) (225) TT
Answer 75TT

<h2>
Step-by-step explanation:</h2>
<h3>
1. Identify the given information.</h3>
a. We have the slope of the line, 1/4.
b. We also have a point of said line, because when the question states "y-intercept 5..." it's telling us that the lines touches the y intercept on the value y= 5, and this only happens when x= 0. Hence, a given point is (0, 5).
• Formula for constructing linear equations.
Formula: 
; where m is the slope of the function; x1 is the x value of a point the function passes through, and y1 is the y value of a point the function passes through.
<h3>2. Substitute in the formula and calculate the equation of the line.</h3>
<h3>3. Graph the line.</h3>
