determine which integers will make the inequailty 5x 6 < 2x 15 flase
The value of x (B) 5 makes the inequality 5x + 6 ≤ 2x + 15 FALSE.
What is inequality?In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to one another.
The equal sign (=) indicates that two expressions in an equation are believed to be equivalent.
The symbols >, <, ≤ or ≥ indicate that the two expressions in inequality are not always equal.
So, we have the inequality:
5x + 6 ≤ 2x + 15
Now put the given values and check as follows:
(A) -2
5x + 6 ≤ 2x + 15
-10 + 6 ≤ -4 + 15
-4 ≤ 11
TRUE
(B) 5
5x + 6 ≤ 2x + 15
25 + 6 ≤ 10 + 15
31 ≤ 25
Correct: 31 > 25
FALSE
Therefore, the value of x (B) 5 makes the inequality FALSE.

the formula would be used to find a) the first quartile of a data set using the inclusive method. b) the third quartile of a data set using the exclusive method. c) the first quartile of a data set using the exclusive method. d) the median of a data set using the inclusive method.
The given formula would be used to find the first quartile of a data set using the exclusive method.
What is quartile?
A quartile is a type of quantile used in statistics that divides the total number of data points into four roughly equal parts, or quarters. To compute quartiles, the data must be arranged from smallest to largest; therefore, quartiles are a type of order statistic.
The given formula is [tex]L_P = (n + 1)\frac{25}{100} \\[/tex]
This formula can also be written as,
[tex]R = (n + 1)\frac{25}{100}[/tex]
where 25 is the percentile of the data set.
So, the option (c) is correct.
The first quartile of a data set using the exclusive method.

which graph shows a polynomial function with a positive leading coefficient?
The graph shows a polynomial function with a positive leading coefficient B.
What is meant by polynomial function with a positive leading coefficient?The function will reach its maximum value of + in the case of a positive leading coefficient and its minimum value of - in the case of a negative leading coefficient. This indicates that even degree polynomials with positive leading coefficients have a range of [ymin, ∞), where ymin stands for the global minimum that the function reaches.
When a variable in an equation like the quadratic equation, cubic equation, etc. has only non-negative integer powers or only positive integer exponents, the function is said to be polynomial.
Leading coefficients are the values listed before the variable with the biggest exponent. They can be positive, negative, real, imaginary, whole, fractional, or decimal, much like conventional coefficients, and they can also be positive, negative, real, or imaginary.
Therefore, the correct answer is option B.

The movie claims that 40% of your brain is used for visual decoding.
Williams, the William G. Allyn Professor of Medical Optics, notes that processing visual information takes up more than 40% of the cortex, the surface of the brain.
Light and dark pixels in the eye are where our visual experience begins. These signals are sent to the V1 region in the rear of the brain, where they are changed to match to the borders of visual scenes.
The visual cortex processes information from the sensory periphery in accordance with a highly regulated hierarchy, according to experiments utilizing static stimuli, such as images. The information about visual sceneries is subsequently translated by deeper brain areas into more intricate forms, objects, and ideas.

If 250 bricks are used to build a wall of 15 ft high then, there is total 1250 bricks will be used to build a wall that is 75 ft high.
Proportion:
A proportion is an equation between two ratios or rates that is useful in solving for a single unknown.
We have given that,
It takes 250 bricks to build a 15 ft high wall. Let us consider x bricks , is needed for a 75 ft high wall, use the ratio given for a 15 ft high wall and equate it to the ratio for the unknown number of bricks for a 75-ft high wall.
In making proportions, make sure that the rate on one side has the same units as the rate on the other as shown :
x/75 = 250/15
=> 15 × x = 250 ×75
=> x = 250×75/15

Answer: m∠5 = 116°
Step-by-step explanation:
Because m∠4 and m∠6 are consecutive interior angles, then we know
m∠4 + m∠6 = 180
(106 - y) + (3y - 10) = 180
104 - y + 3x - 10 = 180
96 + 2y = 180
2y = 84
y = 42
And also the m∠4 and m∠5 are alternate interior angles, we get:
m∠5 = m∠4 = 3y - 10
Since we also calculate what y is, we just plugin.
mm∠5 = m∠4 = 3(42) - 10 = 126 - 10 = 116

find the quotient and remainder when 6x^4+ 11x^3+13x^2 -3x+27 is divided by 3x+4. also check the remainder obtained by using the remainder theorem.
The division of 6x⁴ + 11x³ + 13x² - 3x + 27 by 3x + 4 will have a quotient of 2x³ + x² +3x -5 and a remainder of 47 using the remainder theorem.
What is the remainder theoremThe remainder theorem states that if a polynomial say f(x) is divided by x - a, then the remainder is f(a).
We shall divide the 6x⁴ + 11x³ + 13x² - 3x + 27 by 3x + 4 as follows;
x⁴ divided by 3x equals 2x³
3x + 4 multiplied by 2x³ equals 6x⁴ + 8x³
subtract 6x⁴ + 8x³ from 6x⁴ + 11x³ + 13x² - 3x + 27 will give us 3x³ + 13x² - 3x + 27
3x³ divided by 3x equals x²
3x + 4 multiplied by x² equals 3x³ + 4x²
subtract 3x³ + 4x² from 3x³ + 13x² - 3x + 27 will give us 9x² - 3x + 27
9x² divided by 3x equals 3x
3x + 4 multiplied by 3x equals 9x² + 12x
subtract 9x² + 12x from 9x² - 3x + 27 will give us -15x + 27
-15x divided by 3x equals -5
3x + 4 multiplied by -5 equals -15x - 20
subtract -15x - 20 from -15x + 27 will result to a remainder of 47
using the remainder theorem, x = -4/3 from the the divisor 3x + 4
thus:
f(-4/3) = 6(-4/3)⁴ + 11(-4/3)³ + 13(-4/3)² - 3(-4/3) + 27 {putting the value -4/3 for x}
f(-4/3) = (1536/81) - (704/27) + (208/9) + (12/3) + 27
f(-4/3) = (1536 - 2112 + 1872 + 324 + 2157)/81 {simplification by taking the LCM of the denominators}
f(-4/3) = (5919 - 2112)/81
f(-4/3) = 3807/81
f(-4/3) = 47
Therefore, the quotient of after the division of 6x⁴ + 11x³ + 13x² - 3x + 27 by 3x + 4 is 2x³ + x² +3x -5 and there is the remainder of 47 using the remainder theorem.
