what is the equation of the line that is perpendicular to the line y=-1/2 (X -18) and intersects the Y axis at (0, -1)
Answer:
The equation of the perpendicular line is 2 x + y + 1 =0
Step-by-step explanation:
Step(i) :-
Given equation of the line 2y = x - 18
x - 2y - 18 =0
The equation of the perpendicular line to the given line
b x - ay +k=0
-2 x - y + k =0 this line is passing through the point ( 0 , -1)
⇒ 0 -(-1) + k=0
⇒ 1+k =0
⇒ k = -1
Step(ii):-
The equation of the line is perpendicular to the line
-2x - y - 1 =0
2 x + y + 1 =0
Conclusion:-
The equation of the perpendicular line to the given line 2 x + y + 1 =0
The required equation of the line [tex]l_1[/tex] is perpendicular line [tex]l_2[/tex] is 2x + y +1 = 0
Given ,
The equation of the line [tex]l_1[/tex] is Y = [tex]-\frac{1}{2} ( X- 18 )[/tex]
We have to find ,
The equation of line which perpendicular to [tex]l_1[/tex] and intersects the Y-axis at (0, -1).
According to the question,
[tex]Y = \frac{-1}{2} (X - 18)[/tex]
2Y = -1 ( X - 18)
2Y = -X + 18
2Y + x - 18 = 0
Then , the given line is perpendicular to the line [tex]l_1[/tex] to line [tex]l_2[/tex]
b = 2 , a = 1 ,
bx - ay + k = 0
2x - 1y + k = 0
The intersection point the Y- axis ( 0 , -1 )
2(0) - 1(-1) + k = 0
0 + 1 + k = 0
k = -1
Put the value of k in equation and write the equation at Y - axis
-2x -y -1 = 0
The required line is 2x+y+1 = 0
The required equation of the line [tex]l_2[/tex] is perpendicular line [tex]l_1[/tex] is 2x + y +1 = 0 .

There are 21 students in a class. The median age of the students is 23. The oldest student is 29.
Based on this information, what is the truthfulness of each statement in the table? Select the phrase that best describes each statement.
Statement
Truthfulness
At least one student is 23. Must be true could be true cannot be true
Some students are younger than 15. Must be true could be true cannot be true
Answer:
1) At least one (the 11th) student is 23 (years old), Must be true
2) Some students are younger than 15 Could be true
Step-by-step explanation:
1) The given parameters are;
The number of student in the class = 21
The median age of the student = 23
The age of the oldest student = 29
Therefore, given that the median age = The age of the (n + 1)/2 th student
Where;
n = The number of student in the class = 21
∴ The median age = The age of the (21 + 1)/2 th = 11 th student, when the age of the students are arranged in increasing order, therefore, we have;
At least one (the 11th) student is 23 (years old), Must be true
2) Given that there are 10 students with ages equal to or lower than the median age, and the difference between the median age and the age of the oldest student = 29 - 23 = 6 years, we have;
Some students are younger than 15 Could be true

Angle B is an acute angle in a right triangle. What is a reasonable approximation for angle B if the ratio for the opposite leg divided by the hypotenuse is 0.67?
Answer:
42.1 degrees
Step-by-step explanation:
- since we have a opposite/hypotenuse ratio, that means we used sin x = o/h
- this means, sin x = 0.67
so, x = [tex]sin^{-1[/tex](0.67) {sin inverse}
x = 42.06 degrees, i rounded it up to 42.1 but its up to you (or according to the question)
2x + y = 6
is it linear?
Yes. It's linear. It's one-degree polynomial. You can try plot the graph and It'll give you a line graph.

Celeste married with 4 withholding allowances she earned 1,298 each week find her withholding tax.
Use table(pic)
9514 1404 393
Answer:
$82.28
Step-by-step explanation:
Being married puts Celeste on the right half of the table. Four allowances put her in the 5th section down, where 4 is in the left-most column. Her weekly wage of 1298 puts her wage between 923.30 and 2068.20, so on the second line in that section.
The table tells you to subtract $612.37 from Celeste's weekly wage, then multiply the result by 12% to find her withholding. Doing that, we find the withholding to be ...
(1298.00 -612.37) × 0.12 = $82.28 . . . . rounded up to the nearest cent
The withholding tax applicable to Celeste's earnings is $82.28.

sequence: 2, -6, 18, -54...
Answer:
162 5th term
Step-by-step explanation:
Answer:
5th term =162
Step-by-step explanation:
It is a geometric progression whose nth term = ar^n-1
Where a = 1st term =2
r=ratio of two term= -6/2=-3
n =nth term
So 5th term= 2x-3^5-1
=2x-3^4
=2x81=162 answer
What is the slope of line that passes through the pair of points (4,7,(7,-2)
Answer:
The slope from point (4,7) and (7,-2) is (9,-3)
Step-by-step explanation:
If you plot both points on a graph and go from the (7,-2) one to the (4,7) you would go up 9 and to the left 3 which is why it is negative. It is rise over run
Where to find the slope and y intercept
Answer:
slope: 1
y-intercept: 3
Step-by-step explanation:
The y-intercept is where the line passes through the y axis. It passes through at 3. The slope is 1 because if you apply rise over run it is 1/1 which simplifies to 1.
Hope this helps :)
Answer:
y intercept = 3 slope or m=1
Step-by-step explanation:
y=3 m=1
