BRAINLIEST!!!!<br><br><br> Identify the equation of the translated graph in general form

RUDIKE [14]

Answer:

Hyperbola:

$x^2-y^2-8x+6y-1=0$

Step-by-step explanation:

the given hyperbola has equation:

$x^2-y^2=8$

This is an equation of a hyperbola centered at the origin.

This hyperbola is translated so its center is now at T(4,3)

$(x-4)^2-(y-3)^2=8$

We expand to get:

$x^2-8x+16-(y^2-6y+9)=8$

$x^2-8x+16-y^2+6y-9=8$

$x^2-8x-y^2+6y+7=8$

$x^2-8x-y^2+6y+7-8=0$

$x^2-y^2-8x+6y-1=0$

Mario claims that if the dinominator of a fraction is a prime number, then its decimal form is a repeting decimal. Do you agree?

vodomira [7]

Answer:

I do not agree because Mario's claim is not general.

Step-by-step explanation:

Prime numbers: These are a set of numbers that are divisible by 1 and itself only. Examples are: 2, 3, 5, 7. 11 etc.

And a denominator is the divisor in a given fraction.

Considering the following fractions whose denominators are prime numbers:

$\frac{2}{3}$ = 0.66666666...

$\frac{1}{7}$ = 0.142857142

$\frac{5}{11}$ = 0.45454545...

$\frac{3}{13}$ = 0.23076923

$\frac{1}{7}$ = 0.142857142

It could be observed that Mario's claim is not a general principle which is applicable to all fractions with a prime denominator. Thus, I do not agree with his claim.

Write a system of equations to describe the situation below, solve using any method, and fill in the blanks. Today's cafeteria s

kobusy [5.1K]

Answer:

Equation 1: 14t + 61s = 150

Equation 2: 14t + 25s = 78

Use Elimination (x)

(-1) (14t + 25s) = (78) (-1)

-14t - 25s = -78

14t + 61s = 150

+ -14t - 25s = -78

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

36s = 72

s = 2

Salad costs $2

Then find t

14t + 61(2) = 150

14t + 122 = 150

14t = 28

t = 2

Sandwich costs $2

The sum of a number, n, and a number 5 larger than it is 41.

lina2011 [118]

Answer:

Step-by-step explanation:

If you set the equation up, it would be n + 5 = 41. If you subtract the 5 from both sides to get n by itself, you get n = 36.
