Step-by-step explanation:
12000:
5000 for 1 year
7000 for 3 years
Total interest earned:
9340 - 7000 = 2340
Let x be the irate of simple interst
(5000 x) + (7000(3x)) = 2340
26000x = 2340
x = 0.09
0.09 × 100 = 9%

g(x)=x^3 - 5x^2 + 7x + 13
Express g(x) as a product of linear factors.
g(x)=
Answer:
g = 7 + 13x-1 + -5x + x2
Step-by-step explanation:
Simplifying
g(x) = x3 + -5x2 + 7x + 13
Multiply g * x
gx = x3 + -5x2 + 7x + 13
Reorder the terms:
gx = 13 + 7x + -5x2 + x3
Solving
gx = 13 + 7x + -5x2 + x3
Solving for variable 'g'.
Move all terms containing g to the left, all other terms to the right.
Divide each side by 'x'.
g = 13x-1 + 7 + -5x + x2
Simplifying
g = 13x-1 + 7 + -5x + x2
Reorder the terms:
g = 7 + 13x-1 + -5x + x2

Explain how you know. Is the point (20,24) on line ℓ? Explain how you know. Is the point (80,100) on line ℓ? Explain how you know.
Answer/Step-by-step explanation:
First find the equation of the line. The graph is a proportional graph. Hence, the equation would be in the form is y = kx.
Where k I stye constant of proportionality (y/x).
Using a point on the line, (4, 5),
k = y/x = ⁵/4
Substitute ⁵/4 into y = kx.
Thus, the equation of the graph would be:
y = ⁵/4x
Plug in the value of the x and y coordinates of a point into the equation to determine if the point is on line l. If it makes the equation true, then it is a point on the line.
Thus:
✍️For the point, (20, 24), substitute x = 20, y = 24 in y = ⁵/4x
24 = ⁵/4(20)
24 = 5(5)
24 = 25 (NOT TRUE)
✅Therefore, the point, (20, 24) is not a point on line l.
✍️For the point, (80, 100), substitute x = 80, y = 100 in y = ⁵/4x
100 = ⁵/4(80)
100 = 5(20)
100 = 100 (TRUE)
✅Therefore, the point, (80, 100) IS A POINT on line l.

Step-by-step explanation:
A rectangular field is enclosed by 600 feet of fencing what is the length and feet of the field if it's length is 10 ft more than it's width
Answer:
155 feet
Step-by-step explanation:
600 - 20= 580.
subtract 20 for the two sides of the field that are 10 feet longer than the other two sides
divided 580 by 4 to to get the length of each side of the feild (145 feet) then add 10 feel to get the length 155 feet
The length of the Rectangular field is 155 feet.
What is rectangular?A rectangle is "2D shape that has 4 sides, 4 corners and 4 right angles".
According to the question,
A rectangular field is enclosed by 600 feet of fencing. The length and feet of the field is 10ft more than field's width. so, subtract 20 feet from 600 feet.
600 - 20 = 580 feet
By definition of the rectangular, it has '4 sides' to get length of each sides of rectangular field divide 580 by 4 then we get each sides of rectangle.
[tex]\frac{580}{4}[/tex] = 125 feet.
Now, we have length of each side of the field is 145 feet. But in given question 'length of the rectangular field is 10 feet more than it's width'. So, add 10 feet to the rectangular field.
145 + 10 = 155 feet.
Hence, The length of the Rectangular field is 155 feet.

Step-by-step explanation:
The length of a rectangle is 5 inches more than its vedth. The area of the rectangle is equal to
2 inches more than 4 times the perimeter. Find the length and width of the rectangle.
Answer:
The width = x = 14The length = x+5 = 14+5 = 19Step-by-step explanation:
Let l = length, w = width, A = area = l×w , and P = perimeter = 2(l+w)
Let 'x' be the width
As the length 'l' of a rectangle is 5 inches more than its width.
so the length will be = x+5
As the Area of the rectangle is equal to 2 inches more than 4 times the perimeter.
A = 4P + 2
so the equation becomes
l × w = 4×2(l+w)+2
substituting w=x, l = x+5,
(x+5)x = 8(x+5+x)+2
x²+5x = 8(5+2x)+2
x²+5x = 40+16x+2
x²+5x = 16x+42
x²+5x-16x-42 =0
x²-11x-42=0
[tex]x^2-11x=42[/tex]
[tex]\mathrm{Add\:}a^2=\left(-\frac{11}{2}\right)^2\mathrm{\:to\:both\:sides}[/tex]
[tex]x^2-11x+\left(-\frac{11}{2}\right)^2=42+\left(-\frac{11}{2}\right)^2[/tex]
[tex]x^2-11x+\left(-\frac{11}{2}\right)^2=\frac{289}{4}[/tex]
[tex]\left(x-\frac{11}{2}\right)^2=\frac{289}{4}[/tex]
[tex]\mathrm{For\:}f^2\left(x\right)=a\mathrm{\:the\:solutions\:are\:}f\left(x\right)=\sqrt{a},\:-\sqrt{a}[/tex]
solving
[tex]x-\frac{11}{2}=\sqrt{\frac{289}{4}}[/tex]
[tex]x-\frac{11}{2}=\frac{\sqrt{289}}{\sqrt{4}}[/tex]
[tex]x-\frac{11}{2}=\frac{\sqrt{289}}{2}[/tex]
[tex]x-\frac{11}{2}=\frac{17}{2}[/tex]
[tex]x-\frac{11}{2}+\frac{11}{2}=\frac{17}{2}+\frac{11}{2}[/tex]
[tex]x=14[/tex]
similarly solving
[tex]x-\frac{11}{2}=-\sqrt{\frac{289}{4}}[/tex]
[tex]x-\frac{11}{2}=-\frac{17}{2}[/tex]
[tex]x-\frac{11}{2}+\frac{11}{2}=-\frac{17}{2}+\frac{11}{2}[/tex]
[tex]x=-3[/tex]
so
x = 14, or x = -3
As the width 'x' can not be negative.
so x = 14
Thus,
The width = x = 14The length = x+5 = 14+5 = 19If 3x – 9y = 21 and 6x + 3y = 21, which of these could be a value of x or y?
Answer: x=4, y=-1
Step-by-step explanation:
Multiply the second equation by 3:
18x+9y=63
Then summarize both equations 18x+9y+3x-9y=21+63
21x=84 => x=4
use x=4 in any of initial equations ,for instance in first one:
3*4-9*y=21
12-9*y=21
9y=12-21
9y=-9
y=-1

Answer:
D. 25% decrease
Step-by-step explanation:
When we have multiple choice questions, generally the best first step is to narrow down your options. We can see that our options are either increase or decrease. Obviously, if the class read 40 books in June and then 30 in July, that's a decrease. So option C is out of the question.
We still have three options left, so we have to now figure out the exact percentage decrease. Let's find out what percentage of 40 is 30.
[tex]\frac{30}{40}=0.75[/tex]
(Remember that percentages are parts of 1. 100%=1, 50%=.5)
So 30 is 75% of 40. And what percentage did we go down from 100%? 25%.
There was a 25% decrease in the number of books read.
