Which equation can be used to solve for x in the following diagram?

Answer: C. Jamaal added 4 and 9 to the right hand side in step 4; he should have added 16 and 36. The radius is r=8.

Step-by-step explanation: edge 2020, i took one for the team boys :(

In the given conic equation, Jamaal added 16 and 36 on the left hand side. However, he added 4 and 9 on the right hand side. The radius is r = 8.

What is a general conic equation?

Ax² + Bxy + Cy² + Dx + Ey + F = 0, where x, y are variables and A, B, C, D, E, F are constant terms.

Given,

4x² + 4y² – 16x + 24y – 12 = 0

⇒ 4x² – 16x + 4y² + 24y = 12

⇒ 4(x² – 4x) + 4(y² + 6y) = 12

⇒ 4(x² – 4x) + 16 + 4(y² + 6y) + 36 = 12 + 16 + 36

⇒ 4(x² – 4x + 4) + 4(y² + 6y + 9) = 12 + 16 + 36

⇒ 4(x – 2)² + 4(y + 3)² = 64

⇒ 4(x – 2)² + 4(y + 3)² = (8)²

Therefore, the center is at (2, -3) and the radius is r = 8.

Jamaal must have added 16 and 36 on the rest hand side of the conic equation. That's the mistake Jamaal did. As a result, the value of the radius is wrong when Jamaal solved.

Step-by-step explanation:

Answer:

1. Lin

2. 3 weeks

Step-by-step explanation:

Lin has more money in his account, and after 3 weeks Han and Lin will have the same amount of money in their lunch accounts.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have:

Han starts with $100 in his account. He spends $15 each week on lunches.

Lin starts with $25 in her account and does not spend any of it. Her family adds $10 each week to her account.

For hen:

x be the number of weeks

Total amount left = 100 - 15x

Plug x = 4

Total amount left = $40

For Lin:

y be the number of weeks.

Total amount = 25 + 10y

Plug y = 4

Total amount = 25+40 = $65

Lin has more money in his account.

To have the same amount:

100 - 15x = 25 + 10y

x = y

100 - 15x = 25 + 10x

x = 3 weeks

Thus, Lin has more money in his account, and after 3 weeks Han and Lin will have the same amount of money in their lunch accounts.

Answer:

The answer is "Option C"

Step-by-step explanation:

The using formula[tex]= (1+\frac{r}{n})^n -1[/tex]

→r = rate

→ n = compounded value

In choice a:

When compounded is monthly [tex]4.0784\%[/tex]  

[tex]n = 12[/tex]

[tex]\to (1+ \frac{0.040784}{12})^{12} = 1.0403-1 = 0.0403[/tex]

In choice b:

When compounded is quarterly[tex]4.0792\%[/tex]

[tex]n = 3\\\\\to (1+ \frac{0.040792}{12} )^{3} = 1.0102-1 = .0102[/tex]

In choice c:

x + 3y = 9 ......... (2)

(2) - (1)

(x - x) + (3y - ( - 2y)) = 9 - 14

5y = - 5 ⇒ y = - 1

x + 3( - 1) = 9 ⇒ x = 12

Answer:

-3.6

Step-by-step explanation:

The general equation of a straight line formula is represented as y = mx + c, where m is the gradient or slope of the line and c is called the intercept on the y-axis.

The equation of the line in the question above is y= −3.6x + 59 ,

Therefore comparing both equations together,

y = mx + c = y = −3.6x + 59

m = -3.6

Therefore, the slope of the equation represent in this scenario is -3.6
