Write an equation for a line that is parallel to 9x + 3y = 8 and passes through the point (-1, -4).

Answers

Answer:

y = -3x - 7

Step-by-step explanation:

turn into slope-intercept form:

9x + 3y = 8: subtract 9x to isolate y

3y = -9x + 8: divide by three to isolate again

y = -3x + 8/3 (line): Substitute y and x and replace 8/3 with b

-4 = -3(-1) + b: distribute

-4 = 3 +b: isolate b by subtracting 3

-7 = b

Substitute for b in original equation

y = -3x - 7

Answer:

y=-3x-7

Step-by-step explanation:

First you need to change the equation to slope intercept form. so the equation becomes y=-3x+8/3. now you change it point slope, y-y1=m(x-x1), y--4=-3(x--1), which also becomes y+4=-3(x+1), now you multiply. -3 times x and 1 which makes the equation, y+4= -3x+-3, then subtract from each side since its a positive number. so now the equation y= -3x-7

Answers

Answer:

-81.42 is a rational number

Step-by-step explanation:

[tex] - 81.42 \\ \\ = - \frac{8142}{100} \\ \\ = - \frac{8142 \div 2}{100 \div 2} \\ \\ = - \frac{4071}{50} \\ \\[/tex]

Answer: It is a rational number.

A rational number is a number that can be represented as a fraction.

The fraction can be: [tex]- \frac{4071}{50}[/tex] because:

[tex]-\frac{81.42}{100}[/tex] ÷ 2 = [tex]\frac{40.71}{50}[/tex]

Find the value of this triangle!

Answers

From what I understand, we need to find x, y, and z.

We can easily find x by knowing a triangle has 180°.

Add 72+86=158 and then subtract 180-158 which gets you 22.

Now we have x=22°.

To find y, we first must find z. We can find z using the vertical angles theorem. This means x and z and the same, so z=22°.

Now, we can now find y by adding 70 and 22 = 92.

Subtract 180-92=88°.

All values have been found!

x=22°

y=88°

z=22°

Mario had 12 apples and gave away x apples. Luigi had 26 apples and gave away three times as many apples as Mario did. How many apples did Mario give away if they had the same number of apples left?​

Answers

Answer:

7 Apples

Step-by-step explanation:

For this question, we can write expressions for Maria's apples and Luigi's apples and form an equation as they end up with the same amount.

Mario starts with 12 apples but gives away x number. This means Mario's final amount of apples can be represented as: 12-x

Similarly Luigi starts with 26 and gives away 3 times the amount of Mario. So the number he gave away can be represented as: 3x (3 times the number Mario gave away). Therefore we can represent Luigi's final number as: 26-3x

Since they both end up with the same number of apples, we can put these expressions equal to each other in an equation to solve for x (the number of apples Mario gave away):

Mario             Luigi

12-x       =      26-3x

12-x=26-3x

Now we just need to move the unknowns to one side and the other terms to the other, combine and solve:

12-x-12=26-12-3x

-x=14-3x

-x+3x=14-3x+3x

2x=14

2x/2=14/2

x=7

Mario gave away 7 apples.

Hope this helped!

Two shelters offers dog adoption twice a year ruff had 123 dogs adoption in january 196 fogs adoption in July barks had 78 dogs adoption in January and 135 adoption in July estimates the difference in the number of dogs adoption at each shelter that year

Answers

Answer:

106

Step-by-step explanation:

ruff

123 dogs adoption in january

196 dogs adoption in July

Total adoption for the year = 123 + 196

= 319 adoptions

barks

78 dogs adoption in January

135 adoption in July

Total s like adoption for the year = 78 + 135

= 213 adoptions

Difference in the number of dogs adoption at each shelter that year

= Ruff total adoption for the year - Bark's total adoption for the year

= 319 adoptions - 213 adoptions

= 106

The difference in the number of dogs adoption at each shelter that year is 106

It costs $11.50 to rent a canoe and $5.50 to use the canoe for an hour. You have $28. Write an equation that represents the number h of hours you can rent the canoe

Answers

Answer:

(28 - 11.5) ÷ 5.5

Step-by-step explanation:

So let's examine this question.

We have already payed $11.50 the rent the canoe, so we have $16.50. Divide that by $5.50, and you get 3. So, 3 hours.

Now for the expression.

You start out with $28. You subtract $11.50 from it because it is being used to rent the canoe. You then divide your answer by $5.50 to determine how many hours you can use the canoe for.

Hmm.

(28 - 11.5) ÷ 5.5 = h

(28 - 11.5) ÷ 5.5 = 3

In the process of making a financial forecast, Farid has been looking closely at his
variable expenses. Currently, each week he spends an average of $25 on food, $30 on
entertainment, and $40 on clothing and other purchases. If Farid reduced his variable
expenses in each of these three categories by $7 a week, how much would he save
over the course of one year?

Answers

Answer:

1092

Step-by-step explanation:

first calculate expense for each week;

25+30+40= 95

expense after saving

25-7= 18

30-7=23

40-7=33

18+23+33= 74

total saving for each week= 95-74=21

(you can also just do 7*3=21 to know total saving each week)

weeks in a year=

365 days/7= 52.14 = 52 weeks

total savings for the year= 52*21=$1092

Answer:

$1092

Step-by-step explanation:

There are 3 variables

Food, entertainment and clothing and other purchases

Saving amount is

$7 per each variable per week

Total saving per week is

$7*3 = $21

Saving per year considering 52 weeks per average year is:

$21*52 = $1092
