Which of the following coordinate pairs make the equation x - 9y = 12 true?

Ne4ueva [31]

Options:

(12,0) (0,12) (3,-1) (0,-4/3)

Answer:

(12,0) , (3,-1) and (0,-4/3)

Step-by-step explanation:

Given

$x - 9y = 12$

Required

Which option is true?

A coordinate point is of the form; $(x,y)$

So, we have to substitute the x and y values in the given equation.

A. For (12,0)

$x = 12$ and $y = 0$

$x - 9y = 12$ becomes

$12 - 9*0 = 12$

$12 - 0 = 12$

$12 = 12$

This is true

B. For (0,12)

$x = 0$ and $y = 12$

$x - 9y = 12$ becomes

$0 - 9*12 = 12$

$- 9*12 = 12$

$- 108 = 12$

This is false

C. For (3,-1)

$x =3$ and $y = -1$

$x - 9y = 12$ becomes

$3 - 9*-1 =12$

$3 + 9 =12$

$12 = 12$

This is true

D. For (0,-4/3)

$x = 0$ and $y = -\frac{4}{3}$

$x - 9y = 12$ becomes

$0- 9*-\frac{4}{3} = 12$

$0+ 9*\frac{4}{3} = 12$

$0+ 3*4 = 12$

$0+12 = 12$

$12 = 12$

This is true

Hence, (12,0) , (3,-1) and (0,-4/3) are true values of the equation

CONVERT Fahrenheit TO CELSIUS WITH FORMULA

Maksim231197 [3]

The force F1 = 10 N when d1 = 4 m. The square of 4 m is d1² = 16 m². When d = 2 m, its square is d2² = 4 m². Solving for F2

F2× d2² = F1× d1²

F2 × 4m² = 10 N × 16 m²

F2 = (10 N × 16 m^2) / 4 m² F2

= 10 N× (16 m² /4 m²)

F2 = 10 N × 4

F2 = 40 N

The gravitational force produced when they are kept 2 meters apart is 40 N.

Please help me on this it’s due

<h3>Answer: 5 cakes</h3>

================================================

Explanation:

Let's start off converting the mixed number 12 & 1/4 to an improper fraction.

$a \frac{b}{c} = \frac{a*c+b}{c}\\\\12 \frac{1}{4} = \frac{12*4+1}{4}\\\\12 \frac{1}{4} = \frac{49}{4}\\\\$

Do the same for the other mixed number 2 & 1/3.

$a \frac{b}{c} = \frac{a*c+b}{c}\\\\2 \frac{1}{3} = \frac{2*3+1}{3}\\\\2 \frac{1}{3} = \frac{7}{3}\\\\$

-----------------------

From here, we divide the two fractions. I converted them to improper fractions to make the division process easier.

$\frac{49}{4} \div \frac{7}{3} = \frac{49}{4} \times \frac{3}{7}\\\\\frac{49}{4} \div \frac{7}{3} = \frac{49\times 3}{4\times 7}\\\\\frac{49}{4} \div \frac{7}{3} = \frac{7\times 7\times 3}{4\times 7}\\\\\frac{49}{4} \div \frac{7}{3} = \frac{7\times 3}{4}\\\\\frac{49}{4} \div \frac{7}{3} = \frac{21}{4}\\\\$

The last step is to convert that result to a mixed number.

$\frac{21}{4} = \frac{4*5+1}{4}\\\\\frac{21}{4} = \frac{4*5}{4}+\frac{1}{4}\\\\\frac{21}{4} = 4+\frac{1}{4}\\\\\frac{21}{4} = 5 \frac{1}{4}\\\\$

Note that 21/4 = 5.25 and 1/4 = 0.25 to help check the answer.

-----------------------

Therefore, she can make 5 cakes. The fractional portion 1/4 is ignored since we're only considering whole cakes rather than partial ones.
