Evaluate x/4 + 6 (x - 12) where x = 12:
x/4 + 6 (x - 12) = 12/4 + 6 (12 - 12)
Hint: | Reduce 12/4 to lowest terms. Start by finding the GCD of 12 and 4.
The gcd of 12 and 4 is 4, so 12/4 = (4×3)/(4×1) = 4/4×3 = 3:

A football kicker boots the ball from the 15 yard line to the 35 yard line. The equation can be modeled by the the following: y = - .054(x - h)(x - k).....where h and k are where the football lands (x-intercepts). What was the maximum height that the football reached?
Answers
Answer:
The maximum height that the football reached = 5.4 yards (16.2 feet)
Step-by-step explanation:
The initial location of the ball = 15 yard line
The final location of the ball = 35 yard line
The equation of the ball's motion can be modeled as follows;
y = -0.054·(x - h)·(x - k)
Where;
h and k are the x-intercepts which are the points where the ball lands or where the ball is in contact with the ground
Given that the kicker kicks the ball from the ground on the 15 yard line and the ball lands on the ground at the 35 yard line, we can write
h = 15 yard line
k = 35 yard line
Therefore;
y = -0.054·(x - 15)·(x - 35) = -0.054·x² + 2.7·x-28.35
The maximum height is found by differentiating the function with respect to x and equating the result to 0 as follows;
d(-0.054·x² + 2.7·x-28.35)/dx = 2.7 - 0.108·x = 0
x = 2.7/0.108 = 25
Therefor, at the maximum point, we have;
x = 25
∴ y = -0.054·(25 - 15)·(25 - 35) = -0.054×10×(-10) = 5.4
The maximum height that the football reached = 5.4 yards = 16.2 feet.

Hope This Helps :)
All linear pairs and vertical pairs share the same supplementary angle.
Linear pairs and vertical pairs are both types of angle pairs formed by intersecting lines or by the intersection of a line and a transversal.
1. Linear Pairs: A linear pair consists of two adjacent angles formed by two intersecting lines. The two angles in a linear pair are always supplementary, meaning their measures add up to 180 degrees. In other words, if one angle in a linear pair measures x degrees, then the other angle will measure (180 - x) degrees.
2. Vertical Pairs: Vertical angles are formed by the intersection of two lines. They are opposite angles that share a common vertex but are formed by different pairs of intersecting lines. Vertical angles are congruent, meaning they have the same measure. If one vertical angle measures x degrees, then the other vertical angle formed by the same pair of intersecting lines will also measure x degrees.
Therefore, both linear pairs and vertical pairs share the same property of having angles with equal measures. In the case of linear pairs, the angles are supplementary (their measures add up to 180 degrees), while in vertical pairs, the angles are congruent (they have the same measure).

-2(2u-3)+3u=3(u+8)
u=?
Answers
You get -4u+6+3u=3u+24
And if you simplify that you get:
-u+6=3u+24
Now you need to solve this equation to find u
First bring 3u to the other side to -u-3u (the positive changes to negative)
Now the equation is
-4u+6= 24
Take 6 of both sides
-4u=24-6= 18
-4u= 18
So u= -18/4
Which simplifies to -9/2
Answer: -9/2
Donovan spent 2/15 hour walking to the mailbox, 1/6 hour walking to the library, and 2/10 hour walking to the park. Which took Donovan the longest amount of time to walk to? Explain.
Answers
Answer:
The walk to the park took the longest amount of time
Step-by-step explanation:
In this question, we want to find the location that took Donovan the longest amount of time to work.
We should recall that an hour is 60 minutes
So time spent walking to the mailbox would be 2/15 * 60 = 8 minutes
Time spent walking to the library would be 1/6 * 60 = 10 minutes
Time spent walking to the park = 2/10 * 60 = 12 minutes
So as we can see, the distance taking the longest amount of time to walk is the Park which took a total of 12 minutes
A scientist was in a submarine below sea level, studying ocean life. Over the next ten minutes, she rose 24.2 feet. How many feet had she been below sea level, if she was 0.5 feet below sea level after she rose?
Answers
Answer:
She was initially at a depth of 24.7 feet before she rose
Step-by-step explanation:
To get her initial depth, we need to understand how many feet she sank and rose.
Let us say she was initially at a depth which we can call = x feet.
After 10 minutes she rose for 24.2 feet.
This means her new depth will be x - 24.2 ft.
We are also told that this new depth is actually 0.5 feet below sea level.
This means
x - 24.2 = 0.5
Now that we have this equation we can simply make x the subject of the formula and solve for x
x = 24.2 + 0.5 = 24.7
She was initially at a depth of 24.7 feet before she rose
Answer:
24.7
Step-by-step explanation:
Add 24.2 and 0.5
In the quadratic formula, −b±b2−4ac√2a, what is b2−4ac called?
Answers
Answer:
Step-by-step explanation:
In the quadratic formula x = -b±√b²-4ac/2a, the expression b²-4ac inside the square root is called the discriminant. The discriminant is the function that determines the nature of the roots of the equation even without the constant a, b and c
If b²-4ac > 0, the roots of the equation will be real and distinct
If b²-4ac < 0 the roots of the equation will be complex number
If b²-4ac = 0 the roots of the equation will be real and the same
Does every quadratic equation have at
least one real solution? Explain. (1 point)
A. Yes. When the discriminant is zero, there is exactly one solution. When the discriminant is not zero, there are two unique solutions.
B. No. When the discriminant is greater than zero, there are no real solutions.
C. Yes. When the discriminant is zero, there are two unique solutions. When the discriminant is not zero, there is exactly one solution.
D. No. When the discriminant is less than zero, there are no real solutions.
Answers
Answer:
D. No. When the discriminant is less than zero, there are no real solutions.
Step-by-step explanation:
We have to notice that quadratic equations are second order polynomials whose standard form is:
[tex]y = a\cdot x^{2}+b\cdot x + c \cdot x[/tex], [tex]\forall \,a,b,c\,\in\,\mathbb{R}[/tex]
The factorized form of this polynomial is:
[tex]y = (x-r_{1})\cdot (x-r_{2})[/tex]
Where [tex]r_{1}[/tex] and [tex]r_{2}[/tex] are the roots of the quadratic equation, which may be real or complex.
If we equalize [tex]y[/tex] to zero and make algebraic handling, we can get the value of each root anatically by the Quadratic Formula:
[tex]r_{1,2} = \frac{-b\pm \sqrt{b^{2}-4\cdot a \cdot c}}{2\cdot a}[/tex]
Where [tex]b^{2}-4\cdot a\cdot c[/tex] is known as the discriminant. Then, we should remember the following rules:
i) If discriminant is greater than zero, then the quadratic equation has two different real roots.
ii) If discriminant is zero, then the quadratic equation has two equal real roots.
iii) If discriminant is less than zero, then the quadratic function has two complex roots.
In consequence, we came to the conclusion that statement is false, as quadratic equation have all roots real or all complex, but not one real and the other complex.
In a nutshell, the correct answer is D.

This means that each of these values must be raised to the power of three. Therefore, each of them can be divided by [tex]x^3[/tex].
[tex]x^3 \div x^3 = 1[/tex]

What is the length of
BD with endpoint B(1,4)
and midpoint T(4,6)?
Thank you in advance!
Answers
Answer:
2√13
Step-by-step explanation:
B(1,4) T(4,6) what is BD
find BT
d=√(x2-x1)²+(y2-y1)²
d=√(4-1)²+(6-4)²
d=√3²+2²
d=√9+4
d=√13 this is haf the distance
BD=2d=2√13
A line segment is also a line but a line with finite length and fixed endpoints. The length of BD is 2√13 units.
What is the length of any line on the graph?The distance or length of any line on the graph,
d = √[(x₂- x₁)² + (y₂- y₁)²]
where,
d = distance/length of the line between points 1 and 2,
(x₁ , y₁) = coordinate of point 1,
(x₂ , y₂) = coordinate of point 2,
Given the coordinate of B and T as (1,4) and (4,6), respectively. Therefore, the length of BT can be written as,
Length of BT = √[(x₂- x₁)² + (y₂- y₁)²]
= √[(4 - 1)² + (6 - 4)²]
= √[(3)² + (2)²]
= √(9 + 4)
= √13
Now, we can write the length of BD as the sum of BT and TD,
BD = BT + TD
Since T is the midpoint of BD, therefore, it will divide it into two equal parts, therefore, we can write,
BD = BT + BT
BD = 2(BT)
BD = 2√13
Hence, the length of BD is 2√13 units.
