a student claims y=1 is not a linear equation because it does have the form y=mx+b. Do you agree or disagree explain why
The student is wrong because y = 1 represent lienar equation of a horizontal line. Disagree.
What is Linear Equation in Slope-intercept Form?Equation of a line in slope-intercept form, is y = mx + b, where m is the slope and b is the y-intercept of the linear graph.
Where m (slope) = 0, the linear equation would be, y = b, which suggest that the line is horizontal, and intersects the y-axis at point b.
Therefore, the student is wrong because y = 1 represent lienar equation of a horizontal line. Disagree.

to factor consider the factors of the constant term (- 12) which sum to give the coefficient of the x- term (- 1)
the factors are + 3 and - 4 , since

A garden measuring 8 feet by 12 feet will have a walkway around it. The walkway
has a uniform width, and the area covered by the garden and the walkway is
192 square feet. What is the width of the walkway?
A. 2 feet
B. 3. 5 feet
C. 4 feet
D. 6 feet
By solving a quadratic equation, we will see that the width of the walkway is 3ft.
How to get the width of the walkway?Remember that for a rectangle of length L and width W, the area is:
A = W*L
Now, we know that for our garden we have:
W = 8ft
L = 12ft
If we add a walkway of width x around the garden, then the new measures are:
W' = 8ft + 2x
L' = 12ft + 2x
So the area is:
A' = ( 8ft + 2x)*( 12ft + 2x)
And we know that it is equal to 192 ft^2, then:
192 ft^2 = ( 8ft + 2x)*( 12ft + 2x)
Now we can solve this for x.
192ft^2 = 96ft^2 + 4x^2 + 20ft*x
0 = 96ft^2 - 192ft^2 + 20ft*x + 4x^2
0 = -96ft^2 + 20ft*x + 4x^2
This is a quadratic equation, and the solutions are given by the Bhaskara's formula:
[tex]x = \frac{-20ft \pm \sqrt{(20ft)^2 - 4*4*(-96ft^2)} }{2*4} \\\\x = \frac{-20ft \pm 44ft}{8}[/tex]
We only take the positive solution, so we get:
x = (-20ft + 44ft)/8 = 3ft
So the width of the walkway is 3ft.

To rent a certain meeting room, a college charges a reservation fee of $39 and an additional fee of $9.80 per hour. The math club wants to spend at most $117.40 on renting the meeting room. What are the possible amounts of time for which they could rent the meeting room? Use t for the number of hours the meeting room is rented, and solve your inequality for t.
Answer:
0 < t ≤ 8 (in hours)
Up to (and including) 8 hours
Step-by-step explanation:
Let t = number of hours the room is rented
Given:
Reservation fee = $39Fee per hour = $9.80Maximum total cost = $117.40Create an equation using the given information and solve for t:
⇒ 39 + 9.8t ≤ 117.4
Subtract 39 from both sides:
⇒ 9.8t ≤ 78.4
Divide both sides by 9.8
⇒ t ≤ 8
Therefore, the possible amounts of time for which they could rent the meeting room is 0 < t ≤ 8 (in hours)
Answer:
8 is the very maximum number of hours the room can be rented. As long as 8 is not exceeded, the room is rentable for what money the math club has.
Step-by-step explanation:
Givens
Maximum payment = 117.40Cost per hour = 9.80Fixed charge = 39 dollarsFormula
payment ≥ 39 + 9.80*t where t is in hours.
Solution
117.40 ≥ 39 + 9.80*t Subtract 39 from both sides.
117.40 - 39 ≥9.80*t
78.40 ≥ 9.80*t Divide by 9.8
78.40/9.80 ≥ 9.80*t/9.80
8 ≥ t
Answer t≥ 8

Answer:
A. horizontal velocity is constant at 25 m/s in every interval
B. downward velocity increases by 9.8 m/s each second, to 19.6 m/s, 29.4 m/s, 39.2 m/s, 49.0 m/s
Step-by-step explanation:
A.Since the ball is not rocket-powered, it has no acceleration in the horizontal direction. (We ignore slowing due to air friction.) The horizontal velocity remains constant at 25 m/s.
__
B.The vertical acceleration is given as 9.8 m/s² in the downward direction. That is, each second the ball is in motion, its velocity downward increases by 9.8 m/s. The table can be filled with ...
t = 2 s, v = -19.6 m/s
t = 3 s, v = -29.4 m/s
t = 4 s, v = -39.2 m/s
t = 5 s, v = -49.0 m/s
__
The sign is negative because the direction is downward. Positive is up.
