Answer:

y = 2x - 14

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 2x + 3 ← is in slope- intercept form

with slope m = 2

Parallel lines have equal slopes, thus

y = 2x + c ← is the partial equation

To fid c substitute (5, - 4) into the partial equation

- 4 = 10 + c ⇒ c = - 4 - 10 = - 14

y = 2x - 14 ← equation of parallel line

Answer:

$\huge\boxed{\sf 4\ minutes\ 1.5\ seconds}$

Step-by-step explanation:

3 minutes 59.1 seconds = (3*60) + 59.1 seconds = 180 + 59.1 seconds

=> 239.1 seconds

$\rule[225]{225}{2}$

4 minutes 3.8 seconds = (4*60) + 3.8 seconds = 240 + 3.8 seconds

=> 243.8 seconds

$\rule[225]{225}{2}$

4 minutes 1.6 seconds = (4*60) + 1.6 seconds = 240 + 1.6 seconds

=> 241.6 seconds

$\rule[225]{225}{2}$

Mean = Sum of data / No. of Data

Mean = 239.1 + 243.8 + 241.6 / 3

Mean = 724.5 / 3

Mean = 241.5 seconds

<u>In Minutes and Seconds:</u>

= 241.5 / 60 = 4.025 minutes

= 4 minutes + 0.025 minutes

= 4 minutes + (0.025 * 60) seconds

= 4 minutes 1.5 seconds

$\rule[225]{225}{2}$

Hope this helped!

Despejar la variable <br> 2x al cuadrado + 15= 113

Rudik [331]

Hola!

x = 7 , x = -7

Explicación:

Comienza restando 15 en cada lado:

$2x^{2} + 15 -15=113-15$

Usted obtiene:

$2x^{2} =98$

Ahora divide ambos lados por 2:

$\frac{2x^{2} }{2} =\frac{98}{2}$

Usted obtiene:

$x^{2} =49$

Como la ecuación está al cuadrado, tendrás que hacer:

$x=\sqrt{f(a)} , x=-\sqrt{f(a)}$

que te da: $x=\sqrt{49} , x =-\sqrt{49}$

Entonces:

$\sqrt{49}=7 , -\sqrt{49} = -7$

Solve x - (-9) = -14. -23 23 -5 5

poizon [28]

Answer:

-23 = x

Step-by-step explanation:

-(-9) = 9

The thing with double negatives is that they form a plus sign, so that is really a POSITIVE nine. Therefore you do the inverse to find <em>x</em>: -14 - 9 = -23.

I am joyous to assist you anytime.
