Answer:
1) x^2 - 14x + 44 = 0
(x^2 - 14x + 49) - 5 = 0
(x-7)^2 - 5 = 0
2)Assuming no complex number x...
(x-7)^2 = 5
x-7 = 5
x-7 = -5
x= 12, x=2

The answers to both the subparts of the equations are shown:
(A) Re-written equation by completing the square: (x-7)² - 5 = 0(B) Solutions of the equation: x = 12, x = 2What are equations?Algebraically speaking, an equation is a statement that shows the equality of two mathematical expressions. For instance, the two equations 3x + 5 and 14, which are separated by the 'equal' sign, make up the equation 3x + 5 = 14.So, the equation is:
−34 = x² −14x+10(A) Rewrite the equation by completing the square:
−34 = x² −14x+10x² - 14x + 44 = 0(x² - 14x + 49) - 5 = 0(x-7)² - 5 = 0(B) The solutions of the equation:
(x-7)² = 5x-7 = 5x-7 = -5x= 12, x=2Therefore, the answers to both the subparts of the equations are shown:

Enter the fraction using tenths and the decimal by the model.
Answer:
The fraction would be 5/10 or 1/2 and the decimal would be 0.5
Step-by-step explanation:
5 are shaded in out of 10 so that shaded part would be 5 out of 10 or 5/10. Same goes for the decimal, 5 are shaded which means that is 5 tenths or 0.5.

A backpack is on sale for 30% off. If the sales price is $15.75, what is the original price? Show your work.
Answer:
$22.50
Step-by-step explanation:
As it is 30% off, $15.75 is 70% of the full price. You can then divide 15.75 by 70 [= 0.225] to get 1% of the full price. Multiply 0.225 by 100 to get the full price. 0.225 x 100 = 22.5
We can check that this answer is correct by multiplying 22.50 by 0.7. If you get 15.75 you know the answer is correct as 15.75 is 70% of the full price.

Answer:
y = -0.25x + 40 ; $26,000
Step-by-step explanation:
From the graph attached ;
The regression equation, y could be obtained :
y = mx + c
m = slope = Rise / Run = (y2 - y1) / (x2 - x1)
Slope = (15 - 40) / (100 - 0)
Slope = - 25 / 100
Slope = - 0.25
c = intercept, where the regression line crosses the y-axis, from. The graph, c = 40
The regression equation goes thus :
y = -0.25x + 40 ; y = price of car ; x = number of miles driven
Price of car that has been driven for 56000 miles
y = - 0.25(56) + 40
y = - 14 + 40
y = 26
Hence, price of car is $26,000

A square pyramid. The square base has side lengths of 6.5 meters and the height of 6 meters.
What is the volume of the pyramid?
Answer:
84.5m³
Step-by-step explanation:
The volume of a square. Pyramid is given as :
V = 1/3 * base * height
Base = l² ; l = side length
Base = 6.5² = 42.25 m²
V = 1/3 * 42.25 * 6
V = 42.25 * 2
V = 84.5
The volume of square pyramid = 84.5m³
how do you solve 1/2(6)(h+1)=18
Multiply 6 by 1/2 to get 3
Ow you have :
3( h + 1) = 18
Distribute the 3:
3h + 3 = 18
Subtract 3 from both sides:
3h = 15
Divide both sides by 3:
H = 5

solve the system of substitution y=-2x y=5x-21
Answer:
x = 3 is the answerStep-by-step explanation:
1. Write the equation.
y = -2x
y = 5x - 21
2. Substitute the values.
(-2x) = 5x - 21
3. Solve the equation.
-2x = 5x - 21
-5x - 5x
-7x = -21
4. Both negatives cancel
7x = 21
5. Divide both sides by 7
7x = 21
/7 /7
6. x = 3
7. Check the answer.
-2(3) = 5(3) - 21
-6 = 15 - 21
-6 = -6
x = 3 is the answerHope this helped,

P.S Sorry for taking so long.
Two functions are defined by the equations f(x)=5−0.2x and g(x)=0.2(x+5). all statements that are true about the functions.
Answer:
The true statements are -: A f(3)>0 , C g(-1)=0.8 and D g(-1)< f(-1)
Step-by-step explanation:
Given f(x)= 5- 0.2x and g(x)= 0.2(x+5)
(A) f(3) > 0
Putting this value in the given equation -
f(3) =5 -0.2(3)
f(3)=5 - 0.6
f(3) =4.4
Therefore , f(3) > 0 . This is a true statement .
(B) f(3) > 5
We got the value of f(3) from the above equation,
Therefore , f(3) = 4.4 , hence f(3) > 5 option is False.
(C) g(-1) = 0.8
Taking the second given equation ,
g(-1) = 0.2 ( -1+ 5)
g(-1) = 0.2 (-4)
Therefore, g(-1) = -0.8 . Hence , this statement is true.
(D) g(-1) < f(-1)
g(-1) = -0.8
f(-1) =5 - 0.2(-1)
f(-1) = 5 +0.2
f(-1) = 5.2
Therefore , g(-1) < f(-1) , Hence this option is true.
(E) f(0) =g(0)
f(0) = 5 + 0.2(0)
f(0) = 5
g(0) = 0.2(0+5)
g(0) = 0.2 +5
g(0) = 1
Therefore , f(0)[tex]\neq[/tex] g(0) , Hence , the option is false .
Hence , true statements about the functions are - A , C , D .
