Answer:
x > -3.4
Step-by-step explanation:
1 < (x + 5.5) / 2
first multiply each side by 2
2 < x + 5.5
Then subtract 5.5 from each side
-3.4 < x
x has to be on the left so you switch the hole equation around to get
x > -3.4

will the point (2, 6) be on the graph of y=3x
Answer:
the answer is yes it will
Answer:
yes
Step-by-step explanation:
since (x,y) is 2,6, we can take x as 2 and y as 6. For the answer to be yes, y=3x must be equal to the x and y values. Lets plug in the values. Is (6)=3(2)?
3 times 2 is 6! So the answer is yes.

Tom buys a boat from a friend, and will pay his friend the same amount of money each year until the boat is paid for. The following graph gibes the amount of money, in dollars, Tom owes his friend, as a function of the amount of time, in years.
The graph of amount Tom owes his friend after a given time, t, is a straight line graph with a negative slope
Please find attached the required example of a possible graph that shows the amount Tom owes his friend
Reason:
Let A represent the amount of money Tom buys the boat with, let x
represent the amount of equal payment made and y represents the
amount Tom owes the friend after a given time, t, we have;
y = A - x·t
Therefore, the slope of the graph formed is -x, the y-intercept of the graph
is A, from which the graph that gives the amount of money, in dollars, Tom
owes his friend, as a function of time, in years can be presented as follows,
using example values;
A = $25,000 (Amount the Tom agrees to buy the boat)
x = $5,000 (Amount Tom pays each year for the boat)
By plugging in the above example values, the attached graph can be drawn using MS Excel

Answer:
(c) y = 3x +2
Step-by-step explanation:
The second given point is the y-intercept, telling you that the 'b' in the equation y = mx +b is 2. This eliminates the first and last choices.
Trying the other point in the two remaining equations shows you which one works:
(b) y = -3x +2
-1 = -3(-1) +2 . . . . not true
(c) y = 3x +2
-1 = 3(-1) +2 . . . . true
The equation of the line through the two points is ...
y = 3x +2
_____
Additional comment
If you plot the two points, you see the line connecting them must have a positive slope. Only the third choice has a positive slope and a y-intercept of 2.
What would be the range of possible whole number values (x) for a 3rd side of the triangle with two sides of 5 in. and 8 in.?
& Name one possible value for a third side?
Correct Answer Only
Answer:
Range of the third side of a triangle
Step-by-step explanation:
Any one side of a triangle must be shorter than the sum of the other two sides. Therefore, the third side length x must be between 5 and 35, not including those endpoints: 5 < x < 35. All whole numbers satisfying this range would form a triangle.
20 is a possible value for a third side
If a rock was thrown at t-2.23tp and hits its height at 1.56 meters what was the height of the tower?
Answer:
t = 4.875 s
h(4.875) = 686.25 ft
t ≈ 11.424 s
Step-by-step explanation:
These questions are more easily answered if the equation is written in vertex form. Subtracting the constant and dividing out -16, we get ...
h(t) -306 = -16(t^2 -9.75t)
Adding the square of half the t-coefficient inside parentheses gives ...
h(t) -306 -380.25 = -16(t^2 -9.75t +23.765625)
h(t) = -16(t -4.875)^2 + 686.25
This tells us the maximum height is 686.25 ft at time t = 4.875 seconds.
__
When the rock hits the ground, h(t) = 0, so ...
0 = -16(t -4.875)^2 + 686.25
686.25/16 = (t -4.875)^2 . . . . . subtract 686.25, divide by -16
√42.890625 +4.875 = t ≈ 11.424 . . . . take the square root, add 4.875
The rock hits the ground after about 11.424 seconds.
