Help!? I have to use elimination to solve it btw

Answer:

(-4, 5)

Step-by-step explanation:

The problem is a system of equations where you have two variables and can use the method of eliminate (eliminating one of the variables) to solve. In this case, you will need to multiply one of the fractions by a factor to eliminate a variable. It seems easiest to multiply the first equation by a factor of -5:

-5(x - 3y) = -24 (distribute) -5x + 15y = 120

Add the equations:

-5x + 15y = 120

<u>+5x + 8y = -5</u>

23y = 115 (divide by 23)

y = 5

Solve for 'x': x - 3(5) = -24 or x - 15 = 24 (add 15) x = -4

Ordered pair: (-4, 5)

Identify the zeros of the function f(x) =2x^2 − 2x + 13 using the Quadratic Formula. SHOW WORK PLEASE!! I NEED HELP!!

babunello [35]

Answer:

$x=\frac{1+5i} {2}$ and $x=\frac{1-5i} {2}$

Step-by-step explanation:

we know that

The formula to solve a quadratic equation of the form

$ax^{2} +bx+c=0$

is equal to

$x=\frac{-b\pm\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$f(x)=2x^{2} -2x+13$

Equate the function to zero

$2x^{2} -2x+13=0$

so

$a=2\\b=-2\\c=13$

substitute in the formula

$x=\frac{-(-2)\pm\sqrt{-2^{2}-4(2)(13)}} {2(2)}$

$x=\frac{2\pm\sqrt{-100}} {4}$

Remember that

$i=\sqrt{-1}$

so

$x=\frac{2\pm10i} {4}$

Simplify

$x=\frac{1\pm5i} {2}$

therefore

$x=\frac{1+5i} {2}$ and $x=\frac{1-5i} {2}$

(triangles) if FGH= QRS, find the measure of

mote1985 [20]

Answer:

Option (4)

Step-by-step explanation:

From the picture attached,

ΔFGH ≅ ΔQRS

Therefore, ∠F ≅ ∠Q

m∠F = m∠Q

(2x + 10)° = (3x + 1)°

3x - 2x = 10 - 1

x = 9

m∠Q = (3x + 1)°

= 27 + 1

= 28°

Option (4) will be the correct option.

Six friends each use a $2-off coupon to buy themselves a movie ticket. They spend a total of $42. What is the price of one movie

andrey2020 [161]

Answer:

$9

Step-by-step explanation:

1.) First, divide 42 by 6 since there are six people and the total is $42.

42/6 = 7

2.) Now, add $2 to 7 since 7 was the price of the movie ticket AFTER the $2 were taken off of it

x = 7+2x=9

4.) So, one movie ticket (x) = $9
