Step-by-step explanation:
12x > 9(2x - 3) - 15
12x > 18x - 27 - 15
12x > 18x - 42
42 > 6x
7 > x
so, this is true for all values < 7
so, x is in (-infinity, 7)

HELP ASAP
Answer:
] The three consecutive even numbers are 38, 40 and 42. The smallest of the three is clearly 38. Step-by-step explanation:Even numbers are of the form [math]2k[/math], [math] k \in \mathbb{Z}[/math]. Three consecutive even numbers are of the form [math]2k[/math], [math]2(k+1)[/math], [math]2(k+2)[/math]. We have that their sum is 120 therefore [math]\\2k + 2(k+1) + 2(k+2) = 120 \Leftrightarrow k+(k+1)+(k+2) = 60 \Leftrightarrow 3(k+1) = 60 \\ \Leftrightarrow k+1=20 \Leftrightarrow \boxed{k=19}.[/math

Answer:
[tex]n=3[/tex]
Step-by-step explanation:
Note that [tex]2^5*5^2=2^3*2^2*5^2=2^3*(2*5)^2=2^3*10^2[/tex].
Aha! We see a path to the solution!
We now know that our equation is actually [tex]2^3*10^2=2^{n}*10^2[/tex].
We can divide both sides by [tex]10^2[/tex] to get [tex]2^3=2^{n}[/tex].
By inspection or taking the logarithm base 2 of both sides, we see that [tex]3=n[/tex].
So, the answer is [tex]\boxed{n=3}[/tex] and we're done!
Find the values of p and q such that 4x-5-x^2=q-(x+p)^2
Answer:
p = - 2 , q = - 1
Step-by-step explanation:
Rearrange the left side into standard form
- x² + 4x - 5
Factor out - 1 from - x² + 4x
= - (x² - 4x) - 5
Using the method of completing the square
add/subtract ( half the coefficient of the x- term)² tp x² - 4x
= - (x² + 2(- 2)x + 4 - 4) - 5
= - (x - 2)² - (- 4) - 5
= - (x - 2)² + 4 - 5
= - 1 - (x - 2)²
Comparing to q - (x + p)²
with p = - 2 and q = - 1

Why do you think that diagnosing a parasite infection can be difficult in some cases?
Answer:
They are difficult to diagnose through route medical tests. A careful analysis of signs and symptoms is far more productive in eliciting the diagnoses verses blood tests. At least through suck signs and symptoms the presumptive diagnosis of parasitic infestations can be made. It all just depends though.

why is it important to have a random sample for your data in statistics?
Answer:The simplest random sample allows all the units in the population to have an equal chance of being selected. ... Perhaps the most important benefit to selecting random samples is that it enables the researcher to rely upon assumptions of statistical theory to draw conclusions from what is observed.

B is between A and C. C is between B and D. If BC = 45 and CD is 20. If AB = CD, what is the measure of AD?
AD =
Answer:
AD = 85
Step-by-step explanation:
AD = AB + BC + CD ( substitute values , noting AB = CD = 20 ) , then
AD = 20 + 45 + 20 = 85
Point A is (5, 7).
Point B is (x, y).
The midpoint of AB is (17,-4).
What are the coordinates of B?
A. (22,-9)
B.(12,-11)
C. (29.-15)
D. (8.5,-2)
The coordinate of point B is at (29, -15): Option C is correct.
The formula for calculating the midpoint of two points is expressed as:
[tex]M(x, y) = {\frac{x_2+x_1}{2}, \frac{y_2+y_1}{2}}[/tex]
Given the coordinate points
A is (5, 7).
B is (x, y).
M is (17, -4)
Substituting into the formula to get x and y
17 = 5+x/2
5+x = 34
x = 34 - 5
x = 29
Get the value of y. Similarly;
-4 = 7+y/2
-8 = 7+y
y = -8-7
y = -15
Hence the coordinate of point B is at (29, -15)

Victoria logged in to work at 8:15 am and logged out at 4:25 pm.
How many hours did she work? (Her employer rounds to the nearest quarter hour.)
7 1/2 hours
7 3/4 hours
8 hours
8 1/4 hours
In total Victoria worked for [tex]8 \frac{1}{4}[/tex] hours. Therefore, option D is the correct answer.
Given that, Victoria logged in to work at 8:15 am and logged out at 4:25 pm.
What is clock?A clock or a timepiece is a device used to measure and indicate time. The clock is one of the oldest human inventions, meeting the need to measure intervals of time shorter than the natural units such as the day, the lunar month and the year.
Victoria logged in to work at 8:15 am
8:15 am →9:15 am →10:15 am→11:15 am→12:15 pm→1:15 pm→2:15 pm→3:15 pm→4:15 pm
8:15 am →9:15 am = 1 hour
9:15 am →10:15 am = 1 hour
10:15 am→11:15 am = 1 hour
11:15 am→12:15 pm = 1 hour
12:15 pm→1:15 pm = 1 hour
1:15 pm→2:15 pm = 1 hour
2:15 pm→3:15 pm = 1 hour
3:15 pm→4:15 pm = 1 hour
So, in total Victoria logged in for 8 hours 10 mins

A park district is building an outdoor tennis court based on a scale drawing that measures 30 cm long by 13.75 cm and uses the scale 1 cm:0.8 m. What is the area of the actual tennis court in square meters?
The actual area of the tennis court is 264 m²
First use the scale to find the actual dimensions of the court:
1 cm : 0.8m
30 cm in the drawing would be:
= 0.8 x 30
= 24 m outside
13.75cm in the drawing would be:
= 0.8 x 13.75
= 11 m outside
Area of a rectangle (which is what the dimensions resemble):
= Length x width
= 24 x 11
= 264 m²
In conclusion, the area of the tennis court is 264 m²
Find the missing angle measurement
Answer:
85
Step-by-step explanation:
The sum of two interior angles in a triangle is equal to an exterior angle that is supplementary to the third interior angle.
As you can see in the attached image we can find the measure of the interior angle using the straight line and find the value of missing angle
25 + 60 = 85
what is the measure of F?
pleaseeee
Answer:
D
Step-by-step explanation:
The 3 angles in a triangle sum to 180°
Sum the 3 given angles and equate to 180
2x + 3 + 7x - 5 + 3x + 14 = 180 , collect like terms
12x + 12 = 180 ( subtract 12 from both sides )
12x = 168 ( divide both sides by 12 )
x = 14
Then
∠ F = 7x - 5 = 7(14) - 5 = 98 - 5 = 93° → D
