Answer:
t ≥ 192
Step-by-step explanation:
To isolate t in the inequality 6.50t ≥1248, divide by 6.50 on both sides. There you are left with t ≥ 192 which means the cheerleading team must sell 192 t-shirts or more to make their profit goal. Graph this using a closed circle at 192 moving upwards. (You didn't include a picture of the given graphs in your problem)

cents. A 16 ounce can sells for 65 cents.
Which is the better deal?
Answer:
16 ounce can sells for 85 cents

29cents / 6 ounce = 4.833cents/ounce
65cents / 16 ounce = 4.0625cents/ounce
4.0625 < 4.833
then:
the better deal is:

Tina spent a total of $14.90 on 4 identical notebooks and 3 identical pencils. She
had some money left. If she bought another identical pencil, she would have $0.30
left. If she bought another identical notebook instead, she will be short of $1.50.
How much more does a notebook cost than a pencil?
$14.90 spent with the amount left for an extra pencil or notebook being $0.30 or $1.50 short respectively indicates that a notebook costs $1.8 more than a pencil.
Which method can be used to calculate the difference in costs?Let x represent the cost of a notebook and let y represent the cost of a pencil. The following equations can be obtained;
4•x + 3•y = 14.9...(1)
Let a represent the total money Tina has, which gives;
4•x + 4•y = a - 0.3...(2)
5•x + 3•y = a + 1.5...(3)
Subtracting equation (2) from equation (3) gives;
5•x - 4•x + 3•y - 4•y = a - a + 1.5 - (-0.3) = 1.8
Which gives;
x - y = 1.8...(4) From the above, we have that the difference between the cost of a notebook and pencil is 1.8Multiplying equation (4) by 4 and subtracting the result to equation (1) gives;
4 × (x - y) = 4 × 1.8 = 7.2
4•x - 4•y = 7.2
4•x - 4•x + 3•y - (-4•y) = 14.9 - 7.2 = 7.7
7•y = 7.7
y = 7.7 ÷ 7 = 1.1The cost of a pencil, y = $1.1x - y = 1.8
x = 1.8 + 1.1 = 2.9
Cost of a notebook, x = $2.9The difference between the cost of a notebook and the cost of a pencil is therefore;
x - y = $2.9 - $1.1 = $1.8

Step 1: Place the graph paper in landscape orientation. Measure from the top left hand corner 6 inches right and 5 inches down. This will be your starting point for
your diagram.
Step 2: Using a ruler and index card/protractor create an isosceles Right triangle. Drawing the triangles legs 1 inch straight up from the starting point and 1 inch to the
right of the starting point. Connect the endpoints of the two segments to create your right isosceles triangle.
Step 3: On a separate piece of paper, use the Pythagorean Theorem to calculate the length of the hypotenuse. You only need to do this for the first 8 if you discover a
pattern.
Step 4: Using your original Right triangle, add another leg measuring 1 inch and right angle to the hypotenuse of your original Right triangle. Connect the endpoints
to form a new hypotenuse for your new Right triangle.
Step 5: Show the calculations to find the length of the new hypotenuse.
Step 6: Continue to repeat this process of connecting and drawing new triangles with a side length of 1 inch, using the previous hypotenuse as the other side. Draw
triangles until you are able to measure the square root of 17. You must show all calculations (Step 3) on a separate piece of paper.

31. For the following exercises, given each set of information, find a linear equation satisfying the conditions, if possible.
31. f(-1) = 4 and f(5) = 1
Answer:
The required linear equation satisfying the given conditions f(-1)=4 and f(5)=1 is [tex]$y=\frac{-1}{2} x+\frac{7}{2}$[/tex]
Step-by-step explanation:
It is given that f(-1)=4 and f(5)=1.
It is required to find out a linear equation satisfying the conditions f(-1)=4
and f(5)=1. linear equation of the line in the form
[tex]$$\left(y-y_{2}\right)=m\left(x-x_{2}\right)$$[/tex]
Step 1 of 4
Observe, f(-1)=4 gives the point (-1,4)
And f(5)=1 gives the point (5,1).
This means that the function f(x) satisfies the points (-1,4) and (5,1).
Step 2 of 4
Now find out the slope of a line passing through the points (-1,4) and (5,1),
[tex]$$\begin{aligned}&m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\&m=\frac{1-4}{5-(-1)} \\&m=\frac{-3}{5+1} \\&m=\frac{-3}{6} \\&m=\frac{-1}{2}\end{aligned}$$[/tex]
Step 3 of 4
Now use the slope [tex]$m=\frac{-1}{2}$[/tex] and use one of the two given points and write the equation in point-slope form:
[tex]$(y-1)=\frac{-1}{2}(x-5)$[/tex]
Distribute [tex]$\frac{-1}{2}$[/tex],
[tex]$y-1=\frac{-1}{2} x+\frac{5}{2}$[/tex]
Step 4 of 4
This linear function can be written in the slope-intercept form by adding 1 on both sides,
[tex]$$\begin{aligned}&y-1+1=\frac{-1}{2} x+\frac{5}{2}+1 \\&y=\frac{-1}{2} x+\frac{5}{2}+\frac{2}{2} \\&y=\frac{-1}{2} x+\frac{7}{2}\end{aligned}$$[/tex]
So, this is the required linear equation.

whats the simplest form and the exclusions aka holes
Answer:
[tex]\frac{x-3}{2x-3}[/tex]. hole or removable discontinuity at x=2
Step-by-step explanation:
Well generally if you want the simplest form, you factor each the denominator and numerator and then see if you can cancel any of the factors out (because they're in the denominator and numerator)
So let's start by factoring the first equation:
[tex]x^2-5x+6[/tex]
Now let's find what ac is (it's just c since a=1...)
[tex]AC= 6[/tex]
List factors of -6
[tex]\pm1, \pm2, \pm3, \pm6[/tex].
Now we have to look for two numbers that add up to -5. It's a bit obvious here since there isn't many factors, but it's -2 and -3, and they're both negative since 6 is positive, and -5 is negative...
So using these two factors we get
[tex](x-2)(x-3)[/tex]
Ok now let's factor the second equation:
[tex]2x^2-7x+6[/tex]
Multiply a and c
[tex]AC = 12[/tex]
List factors of 12:
[tex]\pm1, \pm2, \pm3, \pm4, \pm6, \pm12[/tex].
Factors that add up to -7 and multiply to 12:
[tex]-3\ and\ -4[/tex]
Rewrite equation:
[tex]2x^2-4x-3x+6[/tex]
Group terms:
[tex](2x^2-4x)+(-3x+6)[/tex]
Factor out GCF:
[tex]2x(x-2)-3(x-2)[/tex]
Rewrite:
[tex](2x-3)(x-2)[/tex]
Now let's write out the equation using these factors:
[tex]\frac{(x-2)(x-3)}{(2x-3)(x-2)}[/tex].
Here we can factor out the x-2 and the simplified form is:
[tex]\frac{x-3}{2x-3}[/tex]
So we can "technically" define f(2) using the most simplified form, but it's removable discontinuity, so it has a hole as x=2. since it makes (x-2) equal to 0 (2-2) = 0.
there were three parts to Rita's race. she ran the first part, which was 4/9 of the total distance, in 20 minutes. She ran the second part, which was 2/5 of the remaining distance, in 12 minutes. She finally ran the third part in 15 minutes at a speed of 300 meters per minute.
a) How long was the third part of the race?
20+12+15= 32+15 = 47 minutes in total
300 meters per minute
300 * 47 = 14100 meters in total
with this we can see the first race was 4/9 that distance meaning the first race was 6266.6 meters long
14100 - 6266.6 = 7833.3
2/5 of 7833.3 is 3133.32
therefore 7833.3 - 3133.32 will give the distance of the third part of the race
meaning of course the answer is 4699.98 or rounding up 4700 meters for the third race

The measure of each segment will be equal to:
m = (7/8)/5 = 7/(8*5) = 7/40
Now, coordinate R is 2 segments to the left of T, so the coordinate of point R is given by:

Solve x≥0 or x≥−5 and write the solution in interval notation.
The solution for x ≥ 0 and x ≥ -5 is [-5, ∞), in the interval notation.
The interval notations are used to represent numbers between two numbers excluding or including the numbers as per the use. We use the following four interval notations:
[a, b] ⇒ All numbers between a and b including both a and b.
(a, b) ⇒ All numbers between a and b excluding both a and b.
(a, b] ⇒ All numbers between a and b excluding a but including b.
[a, b) ⇒ All numbers between a and b including a but excluding b.
We are asked to write the solution for x ≥ 0 and x ≥ -5 in the interval notation.
We first write each inequality in interval notation:
x ≥ 0 ⇒ x are all numbers greater than 0 including 0. This can be written in the interval notation as [0, ∞). We don't include ∞ as it is indeterminant.
x ≥ -5 ⇒ x are all numbers greater than -5 including -5. This can be written in the interval notation as [-5, ∞). We don't include ∞ as it is indeterminant.
Now, we are asked to solve for x ≥ 0 or x ≥ -5. Since it is 'or', we take unions of the two sets, that is the solution is:
[0, ∞) ∪ [-5, ∞) = [5, ∞).
Therefore, the solution for x ≥ 0 and x ≥ -5 is [-5, ∞), in the interval notation.
