Answer:
Function f is symmetric around point (4, -1). This point is the minimum of the function f
Step-by-step explanation:
The vertex-form of the quadratic function is y = a(x - h)² + k, where
a is the coefficient of x²(h, k) are the coordinates of its vertex pointThe graph of the quadratic function is a parabola symmetric at the vertex point (h, k), which is the lowest or the highest on the graphIf the vertex is the lowest point then, it is minimum, if it is the highest point, then it is maximumLet us solve the question
→ From the given graph
∵ The graph represents a quadratic function f(x)
∵ It has the lowest vertex
∴ The vertex is minimum
∵ The coordinates of the vertex are (4, -1)
∵ The is symmetric around the vertex point
∴ The function is symmetric around point (4, -1)
Function f is symmetric around point (4, -1). This point is the minimum of the function f

Solve the multistep inequality.
4x + 3 < 5x − 6
Answer:
x > 9
Step-by-step explanation:
Isolate the variable, x. Treat the < as an equal sign, what you do to one side, you do to the other.
First, subtract 5x and 3 from both sides of the inequality:
4x (-5x) + 3 (-3) < 5x (-5x) - 6 (-3)
4x - 5x < -6 - 3
-x < -9
Isolate the variable, x. Divide -1 from both sides. Note that when you divide or multiply by a negative number, you must flip the sign:
(-x)/-1 < (-9)/-1
x < -9/-1
x > 9
x > 9 is your answer.

Answer:
x > 9
Step-by-step explanation:

The height y (in feet) of a baseball t seconds after it is hit can be modeled by the function y = −16t2 + 96t + 3. About how long does it take to hit the ground?
Answer:
6.03 seconds
Step-by-step explanation:
Given
[tex]y = -16t\² + 96t + 3[/tex]
To solve this, we simply set the height to 0.
i.e. [tex]y = 0[/tex]
So, we have:
[tex]-16t\² + 96t + 3 = 0[/tex]
Solve using quadratic formula.
[tex]t = \frac{-b+-\sqrt{b^2 - 4ac}}{2a}[/tex]
Where
[tex]a = -16[/tex]
[tex]b = 96[/tex]
[tex]c = 3[/tex]
[tex]t = \frac{-96+-\sqrt{96^2 - 4 * -16 * 3}}{2 * -16}[/tex]
[tex]t = \frac{-96+-\sqrt{9216 +192}}{-32}[/tex]
[tex]t = \frac{-96+-\sqrt{9408}}{-32}[/tex]
[tex]t = \frac{-96+-96.9948452239}{-32}[/tex]
[tex]t = \frac{-96+96.9948452239}{-32}[/tex] or [tex]t = \frac{-96-96.9948452239}{-32}[/tex]
[tex]t = \frac{0.9948452239}{-32}[/tex] or [tex]t = \frac{-192.994845224}{-32}[/tex]
[tex]t = -0.031088913245535[/tex] or [tex]t = 6.0310889132455[/tex]
Since time can't be negative, we have:
[tex]t = 6.0310889132455[/tex]
[tex]t = 6.03\ seconds[/tex] (approximated)

Step-by-step explanation:
The school cafeteria sells three different types of sandwiches: chicken, turkey,
and roast beef. Chicken sandwiches sell for $3, turkey sandwiches sell for
$3.50, and roast beef sandwiches sell for $4. The cafeteria makes 400
sandwiches in total, and, if all sandwiches are sold, the cafeteria will take in
$1375. If the cafeteria makes the same number of chicken sandwiches as it
does turkey sandwiches, how many of each type of sandwich does the school
make? (Hint: Write one equation for the number of sandwiches, one equation
for to amount of money all the sandwiches cost, and an equation that show the
number of chicken and turkey sandwiches are equal.)
No
Answer:
Number of chicken sandwiches = 150
Number of turkey sandwiches = 150
Number of roast beef sandwiches= 100
Step-by-step explanation:
We are told the school cafeteriat makes and sells 3 different types of sandwiches which are; chicken, turkey and roast beef.
Let chicken be x, turkey be y and roast beef be z.
We are told they make 400 sandwiches in total.
Thus;
x + y + z = 400
However, we are told that the cafeteria makes same number of chicken and turkey sandwiches.
Thus, x = y
Thus;
Total is now;
x + x + z = 400
2x + z = 400 - - - (eq 1)
Now,we are told that chicken, turkey and roast beef sandwiches are sold for $3, $3.5 and $4 respectively. Also that the total amount realized from sales is $1375.
Thus;
3x + 3.5y + 4z = 1375
Since x = y. Thus;
3x + 3.5x + 4z = 1375
6.5x + 4z = 1375 - - - (eq 2)
Let's make z the subject in eq 1.
Thus;
z = 400 - 2x - - - (eq 3)
Putting 400 - 2x for z in eq(2) gives us;
6.5x + 4(400 - 2x) = 1375
6.5x + 1600 - 8x = 1375
1600 - 1375 = 8x - 6.5x
225 = 1.5x
x = 225/1.5
x = 150
Putting 150 for x in eq 3 gives;
z = 400 - 2(150)
z = 400 - 300
z = 100
Since x = y. Then y = 150
A family is driving at a steady rate on their vacation. The graph shows the relationship between the time and distance from home. What is the constant of proportionality for this graph?
92 miles per hour
460 miles per hour
46 miles per hour
2/92 miles per hour
Answer:
46 miles per hour. I think I've haven't had a problem as easy as this so I was overthinking a lot
Step-by-step explanation:
in the graph the line is passing through points (2,92) and the time is going by two's so you just divide to get the constant
Answer:
46 miles per hour
Step-by-step explanation:
2x46=92
92÷2=46
92-46=46

Is (-4, 15) a solution to the equation y = -2x + 5? How do you know (PLEASE EXPLAIN HOW YOU KNOW)?
Answer:
Not a solution.
General Formulas and Concepts:
Order of Operations: BPEMDAS
Step-by-step explanation:
Step 1: Define
y = -2x + 5
Solution (-4, 15)
Step 2: Check
Substitute: 15 = -2(-4) + 5Multiply: 15 = 8 + 5Add: 15 ≠ 13Here we see that 15 is NOT equal to 13. Therefore, it is NOT a solution to the equation.

A six-sided number cube is rolled twice.
Choose all of the dependent events.
A. The event that the first roll is a 3 or 4, and the event that the sum of the rolls is greater than 7.
B. The event that the first roll is greater than 3, and the event that the second roll is less than 3.
C. The event that the first rollis even, and the event that the second roll is also even.
D. The event that the first rollis odd, and the event that the sum of the rolls is 8.
E. The event that the first rollis odd, and the event that the second roll is a 1.
Answer: A and D
Step-by-step explanation:
Dependent events mean that one event depends on the outcome of the previous event.
A) If the first roll is a 3, and we want to sum more than 7 with the second roll, then the possible outcomes 5 and 6. Now if the first roll is 4, then the possible outcomes for the second event will be 4, 5 and 6. So you can see how the outcome space of the second event changes depending on the first event, so the events are dependent.
B) Here we do not have dependence, each event only depends on it's own outcome.
C) Again, both events only depend on it's own outcome, so the events are not dependent.
D) This is similar as the case for A, these events are dependent because is not the same if the outcome of the first event is 3, than if the outcome is 5 (the outcome needed for the second roll changes depending on the outcome of the first event)
E) Same as B and C, the events are independent.
Mrs.Burkett has hauled 4 1/4 ton of gravel for a quarry jobsite. If she were to haul 6 5/8 tons more, then how much total gravel would she have been hauled at the jobsite?
Answer:
[tex]10\frac{7}{8}[/tex]
Step-by-step explanation:
You simply add the fractions up!
First thing is that [tex]\frac{1}{4} = \frac{2}{8}[/tex] So we can write the fractions as:
[tex]4\frac{2}{8} + 6\frac{5}{8}=4+6\frac{2+5}{8}=10\frac{7}{8}[/tex] tons of gravel was hauled.
Answer:
7 7/8 ton of gravel
Step-by-step explanation:
Its pretty easy actually. All you need to do is add 4 1/4 and 6 5/8.
Let's simplify it and then make a common denominator! (It is 8)
5 x 2 = 10
4 x 2 = 8
Then add:
10 x 53 = 64
8 8 8
Then simplify! And you get
7 7/8
