What is Linear Equation in 2 variables?
An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero.
Given data ,
g ( x ) = x² - 5 x + 8
To solve for g ( 5 a - 2 ) + 3 g ( 2 a ) , substitute for the value of x
Therefore ,
g ( 5 a - 2 ) = ( 5 a - 2 )² - 5 ( 5 a - 2 ) + 8
= ( 25 a² + 4 - 20 a ) - 25 a + 10 + 8
= 25 a² - 45 a + 22
3 g ( 2 a ) = 3 [ (2 a )² - 10 a + 8 ]
= 3 [ 4 a² - 10 a + 8 ]
= 12 a² - 10 a + 8
And , g ( 5 a - 2 ) + 3 g ( 2 a ) = 25 a² - 45 a + 22 + ( 12 a² - 10 a + 8 )
= 37 a² - 55 a + 30
Hence , the value of the equation will be 37 a² - 55 a + 30

What’s the 69th term of the arithmetic sequence -13, -33, -53
Answers
Answer:
(-1373)
Step-by-step explanation:
a = 1st term = -13
Common difference = d = 2nd term - 1st term
d = -33 - (-13) = -33 + 13
d = -20
n = 69
nth term = a + (n-1)d
69th term = (-13) + 68 * (-20)
= -13 - 1360
= - 1373
For his art project, Dorian is using square tiles of different sizes and colors to make a mosaic. The first three tiles are: 1. A = 5 cm2 2. A = 7 cm2 3. A = 9 cm2
which tile's side lengths will Dorian need to estimate?
Answers
Answer:
3cm²
Step-by-step explanation:
Since the sizes are square tiles, to know the tile's side lengths that Dorian need to estimate, we will use the formula for calculating the area of q square
Area of a square = L²
L is the side length of the tiles
For the tiles with area 7cm²
7 = L²
L² = 7
L = √7
L = 2.65cm
For tiles with area 5cm²
5 = L²
L² = 5
L = √5
L = 2.24cm
For tiles with area 9cm²
9 = L²
L² = 9
L = √9
L = 3.0cm
Since for all the square tiles the length of the tile is ≤ 3 cm, then the tile's side lengths that Dorian will need to estimate is approximately 3cm
Which of the following equations is equivalent to 3(a + 4) – 5(a – 2) = 22?
8a + 22 = 22
8a + 2 = 22
-2a + 2 = 22
-2a + 22 = 22
Answers
Answer:
-2a + 22 = 22
Step-by-step explanation:
Distribute the 3 to both terms in (a + 4) and -5 to both terms in (a – 2) to get 3a + 12 – 5a + 10 = 22. Simplify to get -2a + 22 = 22.

Write and equation passing through the point (-3, 1) that is parallel to y=2x+5
Answers
Answer:
y = 2x + 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 2x + 5 ← is in slope- intercept form
with slope m = 2
Parallel lines have equal slopes, thus
y = 2x + c ← is the partial equation
To find c substitute (- 3, 1) into the partial equation
1 = - 6 + c ⇒ c = 1 + 6 = 7
y = 2x + 7 ← equation of parallel line

Julio is paid 1.4 times his normal hourly rate for each hour he works over 32 hours in a week. Last week he worked 43 hours and earned $535.62. Enter and solve an equation to find Julio's normal hourly rate, r. Complete the explanation how you know that your answer is reasonable.
Answers
Answer:
[tex]r = \$14.71[/tex]
Step-by-step explanation:
Given
Normal Hour = 32 hours
Overtime = Hours above 32
Rate for Overtime = 1.4 times normal rate
Earnings = $535.62
Required
Determine the normal hour pay
First, we need to determine the hours worked overtime.
This is:
[tex]Overtime = 43 - 32[/tex]
[tex]Overtime = 11[/tex]
The equation that binds all the parameters is:
[tex]Earnings = Normal\ Hour * Normal\ Rate + Overtime * Overtime\ Rate[/tex]
This gives:
[tex]535.62 = 21 * r + 11 * 1.4r[/tex]
[tex]535.62 = 21r + 15.4r[/tex]
[tex]535.62 = 36.4r[/tex]
Solve for r
[tex]r = 535.62/36.4[/tex]
[tex]r = \$14.71[/tex]

Expand the terms in the bracket and simplify
That's
[tex]3x + 3 = - 2x + 2 + 6 \\ 3x + 3 = - 2x + 8[/tex]
Add 2x to both sides of the equation
[tex]3x + 2x + 3 = 2x - 2x + 8 \\ 5x + 3 = 8[/tex]
Subtract 3 from both sides of the equation
[tex]5x + 3 - 3 = 8 - 3 \\ 5x = 5[/tex]
Divide both sides by 5
[tex] \frac{5x}{5} = \frac{5}{5} \\ [/tex]
We have the final answer as
x = 1Hope this helps you
