Answer: $\left \{ {{6a+11b=36} \atop {4a-2b=-32}} \right. \n \left \{ {{6a+11b=36} \atop { (-(3)/(2)) *(4a-2b=-32)}} \right.$
$(6a+11b=36)+ (-6a+3b=48)= 6a-6a+11b+3b=36+48 \n 14b=84 \n b=6$
$4a-2(6)=-32 \n 4a=-32+12=-20 \n a=-5$

If y = 2x + 1 were changed to y = x + 1, how would the graph of the new function compare with the first one? A. It would be steeper. B. It would be shifted down. C. It would be shifted left. D. It would be less steep.

Answers

it would be less steep..

remember this general form y =mx + c

where m is the slope and c is the y-axis intercept..

here u have changed only the slope.. the line is sloping 4 times less..

Answer:

Less steep

Step-by-step explanation:

What is the solution of the system of equations -x+3y=6 and -10x-3y=27?

Answers

Answer:
x = -3 and y = 1.

Step-by-step explanation:

The given system of equations is:

-x + 3y = 6 ---(1)

-10x - 3y = 27 ---(2)

To solve this system of equations, we can use the method of elimination or substitution.

Method 1: Elimination

To eliminate the variable y, we can add equations (1) and (2) together:

(-x + 3y) + (-10x - 3y) = 6 + 27

Simplifying the equation gives us:

-11x = 33

Dividing both sides of the equation by -11, we get:

x = -3

Now, we can substitute this value of x into either equation (1) or (2) to find the value of y. Let's use equation (1):

-x + 3y = 6

Substituting x = -3, we have:

-(-3) + 3y = 6

Simplifying the equation gives us:

3 + 3y = 6

Subtracting 3 from both sides of the equation, we get:

3y = 3

Dividing both sides of the equation by 3, we have:

y = 1

Therefore, the solution to the system of equations -x + 3y = 6 and -10x - 3y = 27 is x = -3 and y = 1.

Method 2: Substitution

Let's solve the system of equations using the substitution method.

From equation (1), we can express x in terms of y:

x = 6 - 3y ---(3)

Substitute this expression for x into equation (2):

-10(6 - 3y) - 3y = 27

Simplifying the equation gives us:

-60 + 30y - 3y = 27

Combining like terms, we have:

27y = 87

Dividing both sides of the equation by 27, we get:

y = 3

Now, substitute this value of y into equation (3):

x = 6 - 3(3)

Simplifying the equation gives us:

x = 6 - 9

x = -3

Therefore, the solution to the system of equations -x + 3y = 6 and -10x - 3y = 27 is x = -3 and y = 3.

Both methods lead to the same solution, which is x = -3 and y = 1.

Silvio works at a car wash. He earns $50 per day and $12 per car washed. Silvio wants to earn at least $158 in 1 day.Which inequality represents the number of cars (C) Silvio must wash to reach his goal?

Answers

The required inequality for Silvio to earn more than $158 in one day is, $50 + 12x ≥ 158.

Given that,
Silvio works at a car wash. He earns $50 per day and $12 per car washed. Silvio wants to earn at least $158 in 1 day.
To determine the inequality represents the number of cars (C) Silvio must wash to reach his goal.

What is inequality?

Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.

Here,
Let the number of cars washed by Silvio be x,
According to the question,
Silvio works at a car wash. He earns $50 per day and $12 per car washed.
Total earning of the day = $50 + 12x
Silvio wants to earn at least $158 in 1 day. So, his total earnings of the day must be greater equal to $158.
$50 + 12x ≥ 158.

Thus, the required inequality for Silvio to earn more than $158 in one day is, $50 + 12x ≥ 158.

I got the degree to be 81.81818182 I just don't know how get the minute please do tell how to solve by using calculator or by paper thank you

Answers

Well a clock has twelve hours that make up a full circle, or 360 degrees, so you divide 12 by 360 then multiply by the degree, which in this case is 81.81 and that's the number of hours. (You figure out the minutes by looking at the decimal)

An airliner carries 200 200 passengers and has doors with a height of 70 70 in. Heights of men are normally distributed with a mean of 69.0 69.0 in and a standard deviation of 2.8 2.8 in. Complete parts (a) through (d). a. If a male passenger is randomly selected, find the probability that he can fit through the doorway without bending. The probability is . 6395 . (Round to four decimal places as needed.)b. If half of the 200 200 passengers are men, find the probability that the mean height of the 100 100 men is less than 70 70 in. The probability is nothing . (Round to four decimal places as needed.) c. When considering the comfort and safety of passengers, which result is more relevant: the probability from part (a) or the probability from part (b)? Why? A. The probability from part (a) is more relevant because it shows the proportion of flights where the mean height of the male passengers will be less than the door height. B. The probability from part (b) is more relevant because it shows the proportion of flights where the mean height of the male passengers will be less than the door height. C. The probability from part (a) is more relevant because it shows the proportion of male passengers that will not need to bend. D. The probability from part (b) is more relevant because it shows the proportion of male passengers that will not need to bend. d. When considering the comfort and safety of passengers, why are women ignored in this case? A. There is no adequate reason to ignore women. A separate statistical analysis should be carried out for the case of women. B. Since men are generally taller than women, a design that accommodates a suitable proportion of men will necessarily accommodate a greater proportion of women. C. Since men are generally taller than women, it is more difficult for them to bend when entering the aircraft. Therefore, it is more important that men not have to bend than it is important that women not have to bend.
