Rewrite the equation in slope-intercept form.
x - 19y = 4
Answer:
[tex]y = \frac{1}{19} x - \frac{4}{19} [/tex]
Step-by-step explanation:
[tex]x - 19y = 4[/tex]
Slope intercept form :
y= mx+b
Where ;
m = slope
b = intercept
[tex] - 19y = - x + 4[/tex]
Divide through by -19
[tex] \frac{ - 19y}{ - 19} = - \frac{x}{ - 19} + \frac{4}{ - 19} [/tex]
Simplify
[tex]y = \frac{1}{19} x - \frac{4}{19} [/tex]
Answer:
y = (1/19)x - (4/19)
Step-by-step explanation:
x-19y=4
19=m(slope) write it as 1/19
write 4 as 4/19(represents b or y-intercept)
y=mx+b
m=(1/19)
b=(4/19)
Plug in those numbers into the equation to get: y = (1/19)x - (4/19)

Find the length of KNJ
Step-by-step explanation:
The length of arc KNJ is the circumference of the entire circle minus the measure of the 48 degree arc.
This means the central angle of this sector KNJ is 360-48=312.
Using the arc length formula, we get the arc length is (2)(pi)(16)(312/360)=416pi/15.
Why is an exact answer not necessary for some math problems?
Answer:
Because it can make the problem harder
In maths, if there is a question that has a decimal for example like 33.33333333, then that will make the problem harder to perform, that's why, it's not necessary to take the exact answer for some problems. BUT, IF IT SAYS TO TAKE THE EXACT ANSWER, THEN YOU HAVE TO.

A triangle is shown with its exterior angles. The interior angles of the triangle are angles 2, 3, 5. The exterior angle at angle 2 is angle 1. The exterior angle at angle 3 is angle 4. The exterior angle at angle 5 is angle 6. Which statements are always true regarding the diagram? Select three options. m∠5 + m∠3 = m∠4 m∠3 + m∠4 + m∠5 = 180° m∠5 + m∠6 =180° m∠2 + m∠3 = m∠6 m∠2 + m∠3 + m∠5 = 180°
Answer: 3, 4, 5
Step-by-step explanation:
(1) False, those two angles added together would be equal to angle 1, not 4.
(2) False. Angles 2, 3, 5 added together would make 180, not 3, 4, 5.
(3) True, an interior angle and its corresponding exterior angle are supplementary.
(4) True by the exterior angle theorem.
(5) True because the angles in a triangle add to 180 degrees

In Brazil, it sells for 63.65 Brazilian reals.
The exchange rate of us dollars to Brazilian reals is 1:1.7880.
The cost of a book in dollars will be

6b+7b<6b
Answer:
b is less than or equal to 0
Step-by-step explanation:
if we replace b with 0, the equation is true. if we take a number less then 0, for example -2, the equation is still true.
Answer:
6b-.6=7b
Step-by-step explanation:
∠A and \angle B∠B are vertical angles. If m\angle A=(3x-21)^{\circ}∠A=(3x−21) ∘ and m\angle B=(2x-13)^{\circ}∠B=(2x−13) ∘ , then find the value of x
===============================================
Work Shown:
Vertical angles are always congruent
(angle A) = (angle B)
(3x-21) = (2x-13)
3x-21 = 2x-13
3x-2x = -13+21
x = 8
---------
Extra info:
Use this x value to find each angle
angle A = 3x-21
angle A = 3*8-21
angle A = 24-21
angle A = 3 degrees
angle B = 2x-13
angle B = 2*8-13
angle B = 16-13
angle B = 3 degrees
Both angles A and B are 3 degrees, so this confirms the answer.
Both the angles A and B are 3 degrees, so this confirms that both are vertical angles.
What are vertical angles?Each of the pairs of the opposite angles made by two intersecting lines are called vertical angles.
The Vertical angles are always congruent,
(angle A) = (angle B)
(3x-21) = (2x-13)
3x-21 = 2x-13
3x-2x = -13+21
x = 8
Now Use this x value to find each angle;
angle A = 3x-21
angle A = 3*8-21
angle A = 24-21
angle A = 3 degrees
angle B = 2x-13
angle B = 2*8-13
angle B = 16-13
angle B = 3 degrees
Hence Both the angles A and B are 3 degrees, so this confirms that both are vertical angles.

8. PROM A limo costs $85 to rent for 3 hours plus a 7% sales tax, What is the total cost
to rent a limo for 6 hours?
Answer:
181.9 dollars
Step-by-step explanation:
If it costs 85 dollars for 3 hours we want to double that to get the amount for 6 hours which is 170 dollars. This is before sales tax. You can find the amount after sales tax by multiplying 170 by 1.07. You do this because 100 percent of the cost would be 170 times 1, and 7 percent is .07, so if you want 107 percent of the cost you want to do 170 times 1.07. This works because it takes 7 percent of 170 and adds it to the total cost. You could also do this by 170 times .07. Then add the product to 170. 181.9 is the final answer.

Describe how you can use the factors of a quadratic function to find its zeros.
Answer:
Factorising the equation into brackets can help you identify where the x-intercepts are (where the function cuts the x-axis)
Step-by-step explanation:
When you factorise the equation it would look something like this:
(x + a)(x + b) = 0
This also means:
x + a = 0 and x + b = 0
x = -a and x = -b
Example:
Find where the function y = 2x² + 8x + 6 cuts the x-axis
Factorise the 2 out (highest common factor)
x² + 4x + 3 = 0
(x + 1)(x + 3) = 0
x = -1 or -3
What is the percent change from 125 to 165?
Answer:
32%
Step-by-step explanation:
165/125=1.32
percent change would be 32% because when you add 32 to 100 then divide by 100, you will get the 1.32. and 1.32 is the change in 125 and 165. you would multiply 125 by 1.32 to get 165.

Write the converse of the following statement and determine its truth value:
"If a class has 3 left-handed people and 24 right-handed people, then the ratio of lefties to righties is 1:8"
for brainliest
Answer:
The converse is:
if the ratio of lefties to righties is 1 : 8, then for every 3 left handed people, there are 24 right handed people.
The truth value is:
True
Step-by-step explanation:
The statement can be split into:
p -> If a class has 3 left-handed people and 24 right-handed people,
q -> the ratio of lefties to righties is 1:8
The converse of a conditional statement is:
if q then p
So, we have the converse to be;
if the ratio of lefties to righties is 1 : 8, then for every 3 left handed people, there are 24 right handed people.
The truth value.
For p, we have.
Ratio = 3 : 24
This can be simplified to.
Ratio = 1 : 8
For q, we have:
Ratio = 1 : 8
Since both are true, then the truth value is true
As it emerges from the cross multiplication performed, the statement is correct.
Since it is stated that "If a class has 3 left-handed people and 24 right-handed people, then the ratio of lefties to righties is 1: 8", to determine if this statement is correct the following calculation must be performed:
1 = 3 8 = X 8 x 3 = X 24 = X
Therefore, as it emerges from the cross multiplication performed, the statement is correct.
