Answer:

she messed up at -17=34x

Step-by-step explanation:

she added 8x to each side but she was actually supposed to subtract

The error is 8(x - 3) + 7 = 2x(13) and -17 = 34x.

4 - 17 = -13, not 13

8x - 17 = 26x

-17 = 26x -8

-17 = 18x ( it should be like this, but this is still wrong because it should -26)

The solution is:

8(x - 3) + 7 = 2x(4 - 17)

8(x - 3) + 7 = 2x(-13)

8x - 24 + 7 = -26x

8x - 17 = -26x

8x + 26x = 17

34x = 17

x = 17/34

x = 1/2

Answer:

Step-by-step explanation:

Use formulaic methods. Since she has interest on her money, we have to include it:

i = log(x-4*7)^k

i is the interested amount, x is the variable we use, and k is the number of times. 7 is the interest

i = log(4000-4x7)^2 for 4000 at 7% interest over 2 years

i = log(4000-4x7)^10 for 4000 at 7% interest over 10 years

Amount after 2 years: $30,000

Amount after 10 years: $15,671

Step-by-step explanation:

Chad has a rope that is 24 meters long

He wants to divide the rope so each piece will be 4/7 yards

= 24÷ 4/7

= 24× 7/4

= 168/4

= 42

Hence he can divide the rope into 42 pieces

Answer:

3x² + 8x + 5

Step-by-step explanation:

Subtract the sum of the 2 given sides from the perimeter, that is

9x² + x + 6 - (4x² - 2x + 2x² - 5x + 1)

= 9x² + x + 6 - (6x² - 7x + 1 ) ← distribute parenthesis by - 1

= 9x² + x + 6 - 6x² + 7x - 1 ← collect like terms

= 9x² + 8x + 5

Answer:

d. table A and graph A

Step-by-step explanation:

y=3x

y = 3X is represented by graph B .

y = 3X is represented by table A .

Hence option C is correct .

Given, Equation : y = 3X

Now, to get the values of y substitute x.

Firstly table A:

y = 3X

x = 1 : y = 3

x = 2 : y = 6

x = 3 : y = 9

Thus table A represents the equation .

Next graph B :

Starting point of graph B is origin.

Coordinates of origin : (0,0)

Equation of graph B : y = 3X

Thus graph B represents the equation .

Therefore option C is correct .

Answer:

Step-by-step explanation:

A. Subtract 290 from 450, 450-290= 160

B. The variable e represents the elevation before they started the hike

C. 450+-290= 450-290

The requried elevation before the hike is given as 160 feet and the required equation model of the situation is e + 290 = 450 where e represents the elevation before the hike.

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

a. To find the members' elevation before the hike, we can subtract the increase in elevation from their current elevation. So, their elevation before the hike would be 450 - 290 = 160 feet.

b. In the equation e + 290 = 450, the variable "e" represents the members' elevation before the hike.

c. Han's strategy for finding the beginning elevation involves adding -290 to both sides of the equation e + 290 = 450 to get e = 450 + -290. This is equivalent to subtracting 290 from both sides of the equation e + 290 = 450. Both strategies result in the same equation, e = 160, which tells us that the members' elevation before the hike was 160 feet.

Answer:

40%

Step-by-step explanation: If you have five equal-sized sectors, then the probability that the spinner will stop on 4 and 5 is 40%.

The probability that the spinner will stop on a number greater than 3 will be 0.4 or 40%.

The probability of an event occurring is defined by probability.

Probability is also called chance because if you flip a coin then the probability of coming head and tail is nothing but chances that either head will appear or not.

As per the given,

The spinner below is divided into five equal-sized sectors.

The probability of it stopping more than 3 = probability of stops at 4 + probability of stops at 5.

⇒ 1/5 + 1/5

⇒ 2/5 = 0.4

So, 0.4 x 100 = 40%

Hence "The probability that the spinner will stop on a number greater than 3 will be 0.4 or 40%".

Answer:

a.) yes they are similar shapes, the width for both rugs is 1/2 of the length. This means that they are both similar in shape.

b.) 2:5 (perimeter rug 1 and 2 compared), 4:25 ( area for 1 and 2). The numers in the perimeter ratio are the square root of the numbers in the area ratio.

c.) You will need 648 sq in for the small rug and 4050 sq in for the large rug.

d.) 2:  she has to sell the large rugs x>$9 and the small rugs for s>$1.50

Step-by-step explanation:

total perimeter for rug 1 = 108   For rug 2 = 270

area for run 1 = 648 For rug 2 = 4050

180 ft =  2150 in

The large rug needs two skeins of yarn which cost 9 dollars, if she wants to make a profit she will have to sell them over that price.

You can make 3 small rugs with one skein meaning if she wants to make a profit from the small rugs she has to sell them over 1/3 of the price of the skein (which is sold for $4.50). She will have to sell the small rug for over $1.50

Answer:

[tex]f(1)=-6[/tex]

[tex]f(n)=f(n-1)(-3)[/tex]

Step-by-step explanation:

We are given that

[tex]f(n)=2\cdot (-3)^n[/tex]

We have to complete  the recursive formula of f(n).

Substitute n=1

[tex]f(1)=2\cdot (-3)[/tex]

[tex]f(1)=-6[/tex]

[tex]f(2)=2\cdot (-3)^2=18[/tex]

[tex]f(3)=2\cdot (-3)^3=-54[/tex]

[tex]\frac{f(2)}{f(1)}=\frac{18}{-6}=-3[/tex]

[tex]\frac{f(3)}{f(2)}=\frac{-54}{18}=-3[/tex]

It forms geometric sequence because the ratio of two consecutive terms are equal.

Therefore, the recursive formula

[tex]f(n)=f(n-1)r[/tex]

[tex]f(n)=f(n-1)(-3)[/tex]

Answer:

f(1) = -6

f(n)= f(n−1)⋅ -3

(2x12x4150)/((13650(60+1))=0.1196

0.1196x100=11.96% 0r 12%

Answer:

17.2%

Step-by-step explanation:

given that:

y = 12 months

m = $9,500

n = 60 (because five years is 60 months)

c = (n * $227.50) - m

  = (60 * $227.50) - $9,500

c = 4,150

and now, to substitute the following to the equation:

[tex]\frac{2(12)(4,150)}{9,500(61)} *100[/tex] = 17.2%

Answer:

We are given the path, y=-3x-6

The general form of the straight line is 'y=mx+b', where 'm' is the slope and 'b' is the y-intercept.

Thus, the slope of the given line is -3.

As, we have that the incipient path is perpendicular to the given path.

And, we ken that, 'Product of slopes of perpendicular lines is -1'.

Since, the incipient path passes through the point (-3,3). Superseding the values in the general form, we get,

b= 3+1

b= 4.
