5) Find the value of y.
(21y-1)
(4x+23) (9x-38)
The value of y in the expression (21y-1)=(4x+23)(9x-38) is (103x - 875)/21.
According to the given question
We have a linear equation in two variables
(21y - 1) = (4x + 23)(9x -38)
For finding the value of y solve the above equation by adding and subtracting the like terms.
So, 21y - 1 = 4x(9x -38) + 23 (9x -38)
⇒ 21y - 1 = 48x - 152x + 207x - 874
⇒ 21y - 1 = 103x - 874
⇒ 21y = 103x - 874 + 1
⇒ 21y = 103x - 875
⇒ y = [tex]\frac{103x - 875 }{21}[/tex]
Hence, the value of y in the expression (21y-1)=(4x+23)(9x-38) is [tex]\frac{103x - 875 }{21}[/tex]

The statement that would help to show that ∠2 ≅ ∠4 is ∠1 is supplementary to ∠2 and ∠1 is supplementary to ∠4
Supplementary anglesFrom the question, we are to determine the statement that would help to show that ∠2 ≅ ∠4
By definition, supplementary angles are angles that sum up to 180°
From the given diagram,
∠1 + ∠2 = 180° (Linear pair theorem)
Also,
∠1 + ∠4 = 180° (Linear pair theorem)
Thus,
By the substitution property,
∠2 ≅ ∠4
Hence, the proof that ∠2 ≅ ∠4 is shown by ∠1 is supplementary to ∠2 and ∠1 is supplementary to ∠4

Given m<7=107 and m<4= (8x+1) what is the value of x?
The value of x comes out to be 9.
Here, we are given that m∠7 = 107 and m∠4 = (8x+1)
From the figure given below, we can see that angle 7 and angle 6 are vertically opposite angles. Thus-
angle 7 = angle 6
measure of angle 6 = 107°
Now, angle 6 and angle 4 are opposite interior angles and the sum of opposite interior angles is equal to 180. Thus-
m∠4 + m∠6 = 180
8x + 1 + 107 = 180
8x + 108 = 180
8x = 180 - 108
8x = 72
x = 72/8
x = 9

Sarah took the advertising department from her company on a round trip to meet with a potential client. Including Sarah a total of 8 people took the trip. She was able to purchase coach tickets for $250
and first class tickets for $1250. She used her total budget for airfare for the trip, which was $8000. How many first class tickets did she buy? How many coach tickets did she buy?
Sarah buys 6 tickets for first class and 2 for coach class, finding by using properties of linear equation.
What is linear equation in one variable?
A linear equation which has only one variable is called linear equation in one variable.
Let assume,
Sarah has number of first-class tickets = x
then Sarah has number of coach tickets = 8-x
(Because total tickets she has are 8)
given that
The coach tickets price = $250
The first-class tickets price =$1250
so, from above
[tex]\begin{array}{l}1250 \mathrm{x}+250(8-\mathrm{x})=8000 \\1250 x+250(8)-250(x)=8000 \\1250 x+2000-250 x=8000 \\1250 x-250 x=8000-2000 \\1000 x=6000 \\x=\frac{6000}{1000} \\x=6\end{array}[/tex]

the edge of a cube was found to be 30 cm with a possible error in measurement of .1 cm. use differentials to estimate the percentage error (to the nearest hundredth) in computing (a) the volume of the cube and (b) the surface area of the cube.
a) The volume of the cube is 27,271 cubic centimeter
b) The surface area of the cube is 5,400
Well the edge is 30 cm +- 0.1 cm
Volume will be side cubed, so max estimate for volume is (30.1)^3, and minimum (29.9)^3
So percentage error = [(30.1)^3 - 30^3/ / 30^3 x 100 = 1,00 %
Surface area is 6 x side squared
So max estimate for area is 6 x 30.1^2,
minimum 6 x 29.9 ^ 2
So percentage error = (6 x 30.1^2 - 6 x 30^2) / (6 x 30^2) x 100 = 0.67 %

Prove that the opposite angles of a parallelogram are equal.
The opposite angles of a parallelogram are equal.
x + y = a+ b
Let's consider a quadrilateral ABCD which is a parallelogram with AC as its diagonal.
We know, in parallelograms opposites' sides are parallel.
So, AB∥DC and AD∥BC
Since AB is parallel to DC and AC is the transversal.
By alternate angles,
∠BAC = ∠DCA
y = a -----------------(1)
Similarly, AD is parallel to BC and AC is the transversal.
The alternate angles,
∠DAC = ∠BCA
x = b -----------------(2)
Adding equations ( 1 ) and ( 2 ),
∠BAC + ∠DAC = ∠DCA + ∠BCA
∠BAD = ∠DCB
x + y = a + b
Similarly, we can prove, ∠ADC=∠ABC
Hence proved, opposite sites of a parallelogram are equal.

What is a Function :Function, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable). Functions are ubiquitous in mathematics and are essential for formulating physical relationships in the sciences.
A function is a kind of rule that, for one input, it gives you one output. An example of this would be [tex]Y = x^{2}[/tex] . If you put in anything for x, you get one output for y. We would say that y is a function of x since x is the input value.
We can find the x - intercept,
Set y = 0,
-3x - 2 = 0
Rearrange variables to the left side of the equation,
-3x = 2
Divide both sides of the equation by the coefficient of variable,
