So when you are trying to find the solution to the system of equations make sure that you have it where y= -4/5x-6 and y= -30 are written like this:

-30=-4/5x-6

And then solve for x:

Add 6 on both sides. 

-24=-4/5x

Then multiply by the reciprocal of -4/5.

-5/4*-24=-5/4*-4/5x

x=30 

But then you are gonna want to plug 30 in for x in y=-4/5x-6 to make sure that it is the same as y=-30.

How much does a 5 lb 11 oz roast weigh in grams? ​
Maurinko [17]

Answer:

2268 grams or 2 kg 268 g

Step-by-step explanation:

<u>How to convert Pounds to Grams</u>

1 pound (lb) is equal to 453.59237 grams (g).

1 lb = 453.59237 g

The mass m in grams (g) is equal to the mass m in pounds (lb) times 453.59237:

m(g) = m(lb) × 453.59237

In this case,

Convert 5 lb to grams:

2267.96 approximately convert to nearest thousands.

m(g) = 5 lb × 453.59237 = 2268 g or 2 kg 268 g

The population of a town was 7652 in 2016. The population grows at a rate of 1.6% annually.
Serggg [28]

Answer:

(A) The population's growth rate in equation form is y = (0.016t * 7652) + 7652

(B)  y = (0.016t * 7652) + 7652 =

y = (0.016(8) * 7652) + 7652 =

y = (0.128 * 7652) + 7652 =

y = 979.456 + 7652 =

y = 8631.456 (Or About) 8631

Step-by-step explanation:

(A) Y = the total population of the town. 0.016 is 1.6% just in its original form. T = the year in which were trying to find the town's total population. 7652 is the total population of the town in 2016. With this information, the equation reads, The total population of the town (Y) is equal to 16% (0.016) of the current year's population (T) added to 2016's population of 7652. (This last sentence can also be read what is 1.6% of the towns population in the year were trying to find. Because the population is always growing, 1.6% gets multiplied as to scale with the total population in year T)

(B) We just substitute (T) for 2024, or 8 years after 2016 (2024-2016) and simplify the equation we made.
