Answer:

The answer is

y = 6x + 43

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation of the parallel line we must first find the slope of the original line

The original line is y = 6x + 1

Comparing with the general equation above

Slope = 6

Since the lines are parallel their slope are also the same

Slope of parallel line = 6

The equation of the line using point (-7,1) and slope 6 is

We have the final answer as

y = 6x + 43

Step-by-step explanation:

srry if this is wring, its what i got also pls give brainliest, im trying to get to vituoso :3

What is the answer to<br> -2a-9=6a+15

timurjin [86]

Answer:

$a=-3$

Step-by-step explanation:

$-2a-9=6a+15$

Add 9 to both sides:

$-2a-9+9=6a+15+9$

$-2a=6a+24$

Subtract 6a from both sides:

$-2a-6a=6a+24-6a$

$-8a=24$

Divide both sides by -8:

$\frac{-8a}{-8}=\frac{24}{-8}$

$a=-3$

A 2 kg metal cylinder is supplied with 1600J of energy to heat it from 5°C to 13°C. What is the specific heat capacity of the me

Neporo4naja [7]

Answer:

$c = 100\,\frac{J}{kg\cdot ^{\circ}C}$

Step-by-step explanation:

According to the First Law of Thermodynamics, the heat received by the metal cylinder is equal to the change in the internal energy. That is:

$Q = \Delta U$

$Q = m \cdot c \cdot \Delta T$

The specific heat is clear in the previous expression and finally computed:

$c = \frac{Q}{m\cdot \Delta T}$

$c = \frac{1600\,J}{(2\,kg)\cdot (13^{\circ}C-5^{\circ}C)}$

$c = 100\,\frac{J}{kg\cdot ^{\circ}C}$
