Answer:
x = (3 + 8y) / (y - 1)
Step-by-step explanation:
y = (x + 3) / (x - 8)
Make x the subject
y = (x + 3) / (x - 8)
Cross product
y * (x - 8) = (x + 3)
xy - 8y = x + 3
xy - x = 3 + 8y
Factorize the left hand side of the equation
x( y - 1) = 3 + 8y
Divide both sides by (y - 1)
x = (3 + 8y) / (y - 1)

find the value of a and b?
Answers
9514 1404 393
Answer:
a = -2b = 1Step-by-step explanation:
Subtracting the remainder from the original polynomial gives a polynomial that has (x^2 -1) as a factor. Dividing, we find the quotient and remainder to be ...
(x^5 +ax^3 +bx^2 +x -1)/(x^2 -1) = (x^3 +(1+a)x +b) remainder (2+a)x +(b -1)
Since we want the remainder to be zero, we require ...
2+a = 0 ⇒ a = -2
b -1 = 0 ⇒ b = 1

Find the 62nd term of the following sequence:
(-21, – 27, - 33, - 39,...)
Answers
Answer:
-387
Step-by-step explanation:
First term (T1) = -21 = a
second term (t2) = - 27
common difference (d) = t2 - t1 = - 27 + 21 = - 6
Now
Tn = a + ( n - 1) d
T62 = - 21 + ( 62 - 1 ) - 6

If m angle HJM=145 find m angle MHJ
Answers
Answer:
d. 35°Step-by-step explanation
∠MJH = 180 - 145
= 35°
Assuming the two angles form a straight line then the measure of the other angle is 35°
What are supplementary angles?Supplementary angles are those angles that sum up to 180 degrees. For example, angle 130° and angle 50° are supplementary angles because sum of 130° and 50 is equal to 180°
Given here, m∠HJM = 145° then m∠MHJ = 180° - 145°
= 35°
Hence the measure of the angle is 35°

Step-by-step explanation:
≅ means to be equal to.
☆Angle DGE ≅ EGF.
Therefore, 3x + 8 = 5x - 12
☆Let's solve that equation.
[tex]3x + 8 = 5x - 12 \\ \frac{ - 5x \: \: \: \: \: \: \: = - 5x \: \: \: \: \: \: \: \: }{ - 2x + 8 = - 12} \\ \frac{ \: \: \: \: \: \: \: \: - 8 = - 8}{ \frac{ - 2x}{ - 2} = \frac{ - 20}{ - 2} } \\ x = 10[/tex]
We found the value of x which is 10.
☆Let's Now plug in.
[tex]DGE \\ 3x + 8 \\ 3(10) + 8 \\ 30 + 8 \\ 38[/tex]
and the other:
[tex]EGF \\ 5x - 12 \\ 5(10) - 12 \\ 50 - 12 \\ 38[/tex]
☆They asked for what the angle of DGF measured. So we would have to add both sides
[tex]38 + 38 = 76[/tex]

3 lines are shown. A line with points P, R, N intersects a line with points O, R, M at point R. A line extends from point R to point L in between angle M R P. Marcus states that angle ORP and angle LRP are a linear pair. Which best describes his statement?
Answers
Answer:
Marcus is wrong.
Step-by-step explanation:
As we see from the figure the angles ORP and PRM makes 180 degrees or are supplementary angles.
Marcus is wrong because a linear pair has a sum equal to 180 degrees.
But if we observe carefully the angles ORP and LRP don not together make an angle of 180 degrees. Also these angles do not have opposite rays .
Therefore angles PRM and ORP are linear pair angles but angle ORP and angle LRP are not a linear pair.
These angles do not have opposite arms as uncommon sides .
The linear pair must have
1) 180 degrees
2) opposite rays as uncommon sides
3) common vertex
Answer:
He is incorrect. Ray RO and ray RL are not opposite rays.
Step-by-step explanation:
Marcus is incorrect. In order for angles to be a linear pair, the rays of the angles that don't have a common side point, need to be opposite. This is not true for rays RO and RL, so Marcus's statement is not true.

Find the missing number of each unit rate. 155 = ?1 246 = ?1
worth 15 points!!!
Answers
This is an incomplete question, the correct question is given below.
Find the missing number of each unit rate [tex]\frac{15}{5}=\frac{?}{1}[/tex] and [tex]\frac{24}{6}=\frac{?}{1}[/tex]
Answer : The missing number of each unit rate of [tex]\frac{15}{5}=\frac{?}{1}[/tex] and [tex]\frac{24}{6}=\frac{?}{1}[/tex] are, 3 and 4 respectively.
Step-by-step explanation :
As we know that a unit rate is a rate in which 1 is present in denominator.
Or we can say that,
A unit rate is also called a single unit rate that means it will compare 1 unit of some quantity to a different units of a different quantity.
As we are given that that unit rates:
[tex]\frac{15}{5}=\frac{?}{1}[/tex] and [tex]\frac{24}{6}=\frac{?}{1}[/tex]
Now we have to determine the missing number of each unit rates.
So, we can write the given expression as:
[tex]\frac{15}{5}=\frac{?}{1}[/tex]
When are dividing 15 by 5, we get:
[tex]\frac{15}{5}=\frac{3}{1}[/tex]
Thus, the missing number is, 3
And
[tex]\frac{24}{6}=\frac{?}{1}[/tex]
When are dividing 24 by 6, we get:
[tex]\frac{24}{6}=\frac{4}{1}[/tex]
Thus, the missing number is, 4
what is the solution for X in the equation 1/2 - x + 3/2 equals x - 4
Answers
Answer:
x=3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
1/2−x+3/2=x−4
1/2+−x+3/2=x+−4
(−x)+(1/2+3/2)=x−4(Combine Like Terms)
−x+2=x−4
−x+2=x−4
Step 2: Subtract x from both sides.
−x+2−x=x−4−x
−2x+2=−4
Step 3: Subtract 2 from both sides.
−2x+2−2=−4−2
−2x=−6
Step 4: Divide both sides by -2.
−2x/−2=−6/−2
