Answer:
Step-by-step explanation:
The midpoint of two coordinates (x1, y1) and (x2, y2) is expressed as;
M(X,Y) = {(x1+x2)/2, (y1+y2)/2}
Given the points A(h, k) and B(h,j)
x1 = h, y1 = k, x2 = h, y2 = j
Substitute into the formula;
M(X,Y) = {(x1+x2)/2, (y1+y2)/2}
M(X,Y) = {(h+h/2, (k+j)/2}
M(X,Y) = {(2h)/2, (k+j)/2}
M(X,Y) = {h, k+j/2}
hence the coordinates of point M is {h, k+j/2}

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
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.

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

Solve for x: 3(x + 1) = −2(x − 1) + 6
Answer:
x = 1Step-by-step explanation:
[tex]3(x + 1) = −2(x − 1) + 6[/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

01:57:09 In a city, the distance between the library and the police station is 3 miles less than twice the distance between the police station and the fire station. The distance between the library and the police station is 5 miles. How far apart are the police station and the fire station?
Answer:
Distance between the police station and the fire station be 4 miles
Step-by-step explanation:
Let distance between the police station and the fire station be x miles.
The distance between the library and the police station is 3 miles less than twice the distance between the police station and the fire station.
Distance between the library and the police station [tex]=2x-3[/tex]

Write and equation passing through the point (-3, 1) that is parallel to y=2x+5
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

(a) Solve for x.
Let's see what to do buddy...
_________________________________
The sum of the angles of each n-sided figure is found in the following equation :
[tex](n - 2) \times 180 [/tex]
The question's figure is 5-sindes figure
so the sum the angles equal :
[tex](5 - 2) \times 180 = 3 \times 180 = 540 \\ [/tex]
So we have :
[tex]90 + 107 + 144 + 138 + x = 54 0 \\ [/tex]
[tex]479 + x = 540[/tex]
Subtract the sides of the equation minus 479
[tex]x = 540 - 479[/tex]
[tex]x = 61[/tex]
And we're done.
Thanks for watching buddy good luck.

A company ordered 6-foot long oak boards. The length (l) of the boards that the company received varies from a maximum length of 0.05 inches longer than 6 feet to a minimum length of 0.05 inches shorter than 6 feet. Write and solve an absolute value inequality to represent the possible length (l) of each board in inches.
f(x)=∣9/8 (x−8)∣
Answer:
Absolute value equation is:
|L - 72| ≤ 0.05
Solution is 71.05 ≤ L ≤ 72.5
Step-by-step explanation:
We are told that the length (l) of the boards that the company received varies from a maximum length of 0.05 inches longer than 6 feet to a minimum length of 0.05 inches shorter than 6 feet.
From conversions, 1 ft gives 12 inches. Thus, converting the 6 ft to inches gives us; 6 × 12 = 72 inches
This means that minimum value of L is 72 - 0.05 and maximum is 72 + 0.05.
Thus,the absolute value equation is;
|L - 72| ≤ 0.05
Solving this gives;
L - 72 ≤ 0.05 and -(L - 72) ≤ 0.05
This gives;
L ≤ 72 + 0.05 and -L + 72 ≤ 0.05
L ≤ 72.05 and 72 - 0.5 ≤ L
L ≤ 72.05 and 71.05 ≤ L

i think the answer would be B i think if its wrong i am sorry
Step-by-step explanation:
help i need this done asap
Answer:
look at explanation
Step-by-step explanation:
<ABC and <CBD are supplementary, meaning when added together they equal 180 degrees. So that means 5x + 2x + 5 = 180. Add 5x and 2x together to make 7x, so you are left with 7x+5 = 180. Subtract 5 from both sides to get 7x = 175. Divide 7 on both sides to get x by itself, so you are left with the result x = 25, proving that x does equal 25 degrees.

Michael Fenton sells plumbing supplies to contractors. He earns 3% commission on the first $15,000
in sales, 5% on the next $15,000, and 8% on sales over $30,000. Last month he sold $52,000 worth
of plumbing supplies. What was his total commission?
Answer:
His total commission was: $2,960
Step-by-step explanation:
The commissions that Michael Fenton earns by selling plumbing supplies to contractors has three levels:
On the first $15,000 in sales, he earns 3%
On the next $15,000 in sales, he earns 5%
Over $30,000 in sales, he earns 8%.
Last month he sold $52,000 worth of plumbing supplies. His commissions will be calculated according to the levels reached:
The first $15,000 gave him 3%*15,000=0.03*15,000=$450
From the $52,000 sales, there remains $52,000 - $15,000 = $37,000 for the next levels.
The next $15,000 gave him 5%*15,000=0.05*15,000=$750
Now $37,000 - $15,000 = $22,000 remain for the last level.
Michael earned 8% of $22,000 = 0.08*22,000 = $1,760
His total commission was: $450 + $750 + $1,760 = $2,960

What’s the 69th term of the arithmetic sequence -13, -33, -53
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
