Answer:
[tex](x-4)^{2}[/tex]>0
[tex](x-4)^{2}[/tex]+4>0
so the function is always positive.
Step-by-step explanation:
As [tex](x-4)^{2}[/tex] always positive, because when you square numbers you will get always a positive number.
So [tex](x-4)^{2}[/tex]+4>0, because the (+4) will not effect the answer as (x-4)^{2} will be positive.

Decide weather there is enough information to prove that j is parallel to k. If so state the theorem you would use.
Answer:
Step-by-step explanation:
12). From the picture attached,
Supplementary angle of the angle measuring 113° = 180° - 113° = 67°
Since, angles measuring 67° as shown in the figure are the alternate interior angles,
Therefore, by the converse of alternate interior angles theorem, lines j and k will be parallel.
13). Angles formed on the one side of the parallel lines and the transverse line are equal in measure (90°).
Therefore, by the converse of corresponding angles postulate, lines j and k will be parallel.
72% of the total number of students in a school are boys. If there are 1800 boys, find the total
number of students. Also find the ratio of the number boys to the number of girls.
Answer:
total number of students is 2500
ratio is 18:7
Step-by-step explanation:
we can use cross multiplicationsince 72% of the school are boys and number of boys is 1800
means that :
72% * x = 1800
NB : is the number of students in the school
x = 1800/72%
x = 1800/0.72
x = 2500
total number of students is 2500
the number of girls in the school
2500 - 1800
= 700 girls
ratio of boys to girls1800 : 700
can divide by 100
18 : 7

What is the value of x
Answer:
x = 55
Step-by-step explanation:
125 is a corresponding angle to the supplesmntary angle of x. ( the angle next to x, the one that completes x to make it 180, is the same value as 125)
180 - 125 = 55
x = 55
- hope this makes sense
Based on the consecutive exterior angles theorem, the value of x is calculated as: 55°
What are Consecutive Exterior Angles?Consecutive exterior angles are exterior angles that lie on same side of the transversal, and on the parallel lines the transversal cuts.Consecutive exterior angle are supplementary, meaning their sum equals 180°.Therefore,
x = 180° - 125°
x = 55°

The Pythagorean theorem is a basic relationship between the three sides of a right triangle in Euclidean geometry. The length of the line is √136. Thus, the correct option is D.
What is Pythagoras theorem?The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a basic relationship between the three sides of a right triangle in Euclidean geometry. The size of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides, according to this rule.
As per the given graph, the vertical length of the line is 6 units, while the horizontal length of the line is 10 units. Therefore, using the Pythagorean theorem we can write the length of the line as,
Length² = 6² + 10²
Length = √(36 + 100)
Length = √136
Hence, the length of the line is √136. Thus, the correct option is D.

Explain how you determined the ordered pair was a solution to the inequality 4x - 2y < 22.
Answer:
Step-by-step explanation:
Given the inequality 4x - 2y < 22, to get the ordered pair of the inequality, we will have to set x = 0 and y = 0 and then solve for the corresponding inequalities as shown;
when x = 0;
4(0)-2y < 22
-2y < 22
Divide both sides by -2
-2y/-2 > 22/-2
y > -11
When y = 0
4x - 2(0)<22
4x < 22
x < 22/4
x < 11/2
Hence the ordered pair for the inequality expression are y > -11 and x< 11/2
Q(x) = x³ − 3x² + 6x – 2
Q(0)=
Q(1)=
Q(-2)=
Answer:
Q(0) = -2
Q(1) = 2
Q(-2) = -34
Step-by-step explanation:
Step 1: Define
Q(x) = x³ - 3x² + 6x - 2
Q(0) is x = 0
Q(1) is x = 1
Q(-2) is x = -2
Step 2: Substitute and Evaluate
Q(0) = 0³ - 3(0)² + 6(0) - 2
Q(0) = 0 - 0 + 0 - 2
Q(0) = -2
Q(1) = 1³ - 3(1)² + 6(1) - 2
Q(1) = 1 - 3 + 6 - 2
Q(1) = -2 + 6 - 2
Q(1) = -4 + 6
Q(1) = 2
Q(-2) = (-2)³ - 3(-2)² + 6(-2) - 2
Q(-2) = -8 - 3(4) - 12 - 2
Q(-2) = -8 - 12 - 14
Q(-2) = -20 - 14
Q(-2) = -34

Write the SLOPE-INTERCEPT FORM equation given a slope of -1/2 and the point (6,-1).
Answer:
The answer is
[tex]y = - \frac{1}{2} x + 2[/tex]Step-by-step explanation:
To find an equation of a line when given the slope and a point we use the formula
[tex]y - y_1 = m(x - x_1) [/tex]
where
m is the slope
( x1 , y1) is the point
From the question the point is (6 , - 1) and slope - 1/2
So we have
[tex]y + 1 = - \frac{1}{2} (x - 6) \\ y + 1 = - \frac{1}{2} x + 3 \\ y = - \frac{1}{2} x + 3 - 1 \\[/tex]
We have the final answer as
[tex]y = - \frac{1}{2} x + 2 \\ [/tex]

What is the slope of a line perpendicular to y = 2x + 3
Answer:
-1/2
Step-by-step explanation:
The slope of a perpendicular line is opposite reciprocal. So the opposite of 2 is -2, and the reciprocal of 2 is 1/2.
Answer:
[tex]\boxed {\tt m= -\frac{1}{2}}[/tex]
Step-by-step explanation:
Perpendicular slopes are negative reciprocals.
First, let's find the slope of the line. The equation is:
y=2x+3
This line is in slope-intercept form: y=mx+b. m is the slope and b is the y-intercept. Therefore, 2 is the slope.
Now, find the perpendicular slope.
1. Negate the slope
The slope is 2. Negate the slope, or switch the sign. It becomes -2.
2. Find the reciprocal
To find the reciprocal, switch the numerator and denominator.
The slope -2 is equal to -2/1. Switch the top number and bottom number and the result is -1/2.
The perpendicular slope is -1/2
