Determine the value of each variable.
Answer:
a=9, b=45, c=31.5, d=18, f=27
Step-by-step explanation:
To find the value of a, you can take 72-54=18 and do 18/2=9
a=9
To find the value of b, you can multiply the three a's. 27 is the product of the 3 a's. Next, you will do 72-27 to find the value of b
b=45
To find the value of c, you can take 9 and subtract it from 72, or in other words: 72-9=63. You will then divide 63/2 to find the value of c
c=31.5
To find the value of d, you can multiply (9*4)=36. You can then take 72-36 and get 36. To find the value of d, you will then divide 36/2.
d=18
To find F, you are given a clue that 1 a and 1 d together=f.
9+18=f
f=27
Answer:
a=9
b=36
c=45
d=31.5
f=40.5

Answer:
k=9
Step-by-step explanation:
2 × 9 = 18 which is the same as 9 + 9=18
Consider the line - 3x +9y = 5.
Find the equation of the line that is perpendicular to this line and passes through the point (5, -1).
Find the equation of the line that is parallel to this line and passes through the point (5, -1).
Answer:
[tex]\textsf{Perpendicular to given line}:y=-3x+14[/tex]
[tex]\textsf{Parallel to given line}: y=\dfrac13x-\dfrac83[/tex]
Step-by-step explanation:
Rewrite the given equation to make y the subject:
[tex]\begin{aligned}-3x+9y &=5 \\ \implies 9y &=3x+5 \\ \implies y &=\dfrac13x+\dfrac59\end{aligned}[/tex]
Therefore, the slope of the given equation is [tex]\frac13[/tex].
If two lines are perpendicular to each other, the product of their slopes will be -1. Therefore, the slope (m) of the line that is perpendicular to the given line is:
[tex]\begin{aligned}m \times \dfrac13 & =-1\\ \implies m & =-3\end{aligned}[/tex]
To find the equation of the line, substitute the found slope (-3) and the point (5, -1) into the point-slope form of a linear equation:
[tex]\begin{aligned}y-y_1 & =m(x-x_1)\\ \implies y-(-1) &=-3(x-5) \\ y+1 & =-3x+15 \\ y &=-3x+14\end{aligned}[/tex]
If two lines are parallel to each other, their slopes will be the same. Therefore, the slope (m) of the line that is parallel to the given line is [tex]\frac13[/tex]
To find the equation of the line, substitute the slope ([tex]\frac13[/tex]) and the point (5, -1) into the point-slope form of a linear equation:
[tex]\begin{aligned}y-y_1 & =m(x-x_1)\\\\ \implies y-(-1) &=\dfrac13(x-5) \\\\ y+1 & =\dfrac13x-\dfrac53 \\\\ y &=\dfrac13x-\dfrac83\end{aligned}[/tex]
Slope =m=1/3
Note that perpendicular lines have slopes negative reciprocal to each other .
Slope of the perpendicular line=-3Equation in point slope form
y+1=-3(x-5)y+1=-3x+15y=-3x+14And
parallel lines have equal slope

What is the graph of each function? 4. y = -x² - 6x - 11
Answer: The graph will appear as a parabola opening downwards with a maximum point. It will cut the y-axis at -11.
Step-by-step explanation:
The coefficient of x^2 is negative, thus the graph will look "sad" ie. max a maximum point and open downwards. And bc it's x^2, it's a parabola.
Sub. x=0 and you'll get -11. Or just inspect and get the ans from the eqn.

5. How long is the diagona of a 12 ft-by-16 ft rectangular garden?
A. 6 ft
B. 14 ft
C. 18 ft
D. 20 ft
Answer:
The correct answer is option D, 20ft
Step-by-step explanation:
After drawing the picture below, you can just use pythagorean theorem to solve for the diagonal, or the hypotenuse in this case;
(Length)² + (Width)² = (Diagonal)²
(16)² + (12)² = (Diagonal)²
256 + 144 = (Diagonal)²
400 = (Diagonal)²
[tex]\sqrt{400}[/tex] = [tex]\sqrt{Diagonal^{2} }[/tex]
20 = Diagonal
Hope this helps!
Answer:
D. 20 ft
Step-by-step explanation:
Use pythagorus! We can imagine the rectangle is split into 2 equal triangles, one side of the triangle being 12, and the width being 16.
Pythagorus theorum is used to calculate the hypotenuse (long side) of a right-angled triangle. This is the formula:
[tex]\sf{a^{2}+b^{2} = c^{2} }[/tex]
So, we do 12^2 (squared) + 16^2 =
144 + 256 = 400
Now, we have to find the square root of 400, which is equal to
20
So our answer is 20ft
Hope this makes sense! If you need further explanation, do let me know...

Benson has a bankruptcy on his credit report, so he pays higher interest rates on his current loans. he calculates that the extra money he pays in additional interest each year, if invested at the rate of 2% for one year, could earn him simple interest totaling $180. how much does benson pay in additional interest each month? a. $360 b. $750 c. $900 d. $1,000 please select the best answer from the choices provided. a b c d
The additional interest Benson pay each month is $750 if he invested at the rate of 2% for one year, option (b) is correct.
What is simple interest?It is defined as the interest on the based on the principal amount, it does not include the compounded amount. The interest calculate on the initial amount or borrowed amount.
We know the formula for the simple interest is given by:
I = PRT
Where I is the simple interest.
P is the principal amount
R is the rate of interest
We have in the question:
I = $180
R = 2% = 0.02
T = 1 year
Put the above values in the formula, we get:
180 = P(0.02)(1)
P = $9000
The additional interest Benson pay each month is:
= 9000/12
= $750
Thus, the additional interest Benson pay each month is $750 if he invested at the rate of 2% for one year option (b) is correct.

Which statement is true of a rectangle that has an area of 4x2 39x – 10 square units and a width of (x 10) units? the rectangle is a square. the rectangle has a length of (2x – 5) units. the perimeter of the rectangle is (10x 18) units. the area of the rectangle can be represented by (4x2 20x – 2x – 10) square units.
The length and width of the rectangle are (4x - 1) and (x + 10) then the perimeter of the rectangle is 10x + 18. Then the correct option is C.
What is a factorization?It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.
The polynomial of the rectangle will be given below.
4x² + 39x – 10
The factor of the polynomial will be
(4x - 1)(x + 10)
