solve the system by substitution -4x+3y=-2 y=x-1

Answers

Answer:

Substitute y=x-1 for y in the first equation to get -4x+3(x-1)=-2

-4x+3x-3=-2    

-x-3=-2

-x=1

x=-1

Step-by-step explanation:

Answer:

x = -1

y = -2

Step-by-step explanation:

If you look at the second equation, y is already isolated for us:

y = x - 1

so all we need to do is plug in the value for y into the first equation:

-4x + 3(x - 1) = -2

Next all we do is algebra:

[distribute] -4x + 3x - 3 = -2

[condense] -1x - 3 = -2

[add] -1x = 1

[divide] x = -1

Now that we have the value of x, we can use it to find y by plugging it in to either equation.

y = x - 1

[plug in] y = -1 - 1

[condense] y = -2

Answers: x = -1, y = -2

Answers

Answer:

The answer is (x + 3) (x - 7) = 0

Step-by-step explanation:

x² - 4x = 21

x² - 4x - 21 = 0

x² - 7x + 3x - 21 = 0

x(x - 7) + 3(x - 7) = 0

(x + 3) (x - 7) = 0

Thus, The answer is (x + 3) (x - 7) = 0

Option C and D!

Step-by-step explanation:

Option C because:-

When 9 is placed in the box after 7, we get:-

7 ÷ 9 = [tex]\frac{7}{9}[/tex] which is correct!

7 ÷ 9 can also be written as [tex]\frac{7}{9}[/tex]. So, this Option is right since the equation is correct when 9 is placed in the box!

Option D is also correct because,

When we place 9 in the box before [tex]\frac{1}{9}[/tex], we get:-

9 ÷ [tex]\frac{1}{9}[/tex] = 81

9 ÷ [tex]\frac{1}{9}[/tex]  equals 9 x 9 (take the reciprocal of [tex]\frac{1}{9}[/tex])

9 x 9 equals 81 which means the equation is correct when 9 is placed in the box!

c and d are the correct answers !

Answer:

It would be 3 1/2!

Step-by-step explanation:

Because it is X by Y (Usually) AKA bottom row to side row so, it is in the middle of 3 and 4 so it would be 3 1/2!

Answer:

( 3, 3.5) or 3 1/2

Step-by-step explanation:

The cordinate is ( 3, 3.5) but if it has a fraction form like your question had all you want to do is convert 3.5 into a fraction. 3.5 into a fraction is 3 1/2 the 0.5 becomes 1/2 and the 3 is a 3. So the answer is 3 1/2 or ( 3, 3.5).

[tex]\\(87)+(3) = 90\\\\(6)x+(10) = 90[/tex]

in a class of students, the following data table summarizes how many students have a brother or sister. What is the probability that a student chosen from randomly from the class does not have a sister? ​

Answers

Answer: 13/28
Explanation:

Answer:

Step-by-step explanation:

The fact that the student does not have a brother either only means that you have chosen an only child. So there are 13 people that do not have a sister. The 13 comes from the bottom row. 9 + 4 = 13

What is the total number of people in the class? There must be 15 more who do have a sister.

15 + 13 = 28

So the answer should be 13 / 28 or 0.464

Used car auctions give car dealers an opportunity to increase their used car inventory by purchasing cars used as rental cars, assigned to company executives, and other similar activities. Suppose population 1 is all black cars sold at used car auctions, and population 2 is all white cars sold at used car auctions. Of interest is to estimate the difference in the mean sale price of all black cars sold at used car auctions and the mean sale price of all white cars sold at used car auctions. Based on this, using both the appropriate symbol and in words, state the one parameter of interest.

a. The parameter of interest is μ the difference in the mean sale price of all black cars sold at used car auctions and the mean sale price of all white cars sold at used car auctions.
b. The parameter of interest is μ1, the mean sale price of all black cars sold at used car auctions.
c. The parameter of interest is μ1-μ2, the difference in the mean sale price of all black cars sold at used car auctions and the mean sale price of all white cars sold at used car auctions.
d. The parameter of interest is μ2, the mean sale price of all white cars sold at used car auctions.

Answers

Answer:

c. The parameter of interest is μ1-μ2, the difference in the mean sale price of all black cars sold at used car auctions and the mean sale price of all white cars sold at used car auctions

Step-by-step explanation:

Of interest is to estimate the difference in the mean sale price of all black cars sold at used car auctions and the mean sale price of all white cars sold at used car auctions.

The parameter of interest is the difference. Suppose we have that [tex]\mu_1[/tex] is the mean sale price of all black cars sold at used car auctions, while [tex]\mu_2[/tex] is the the mean sale price of all white cars sold at used car auctions. Since the parameter of interest is the difference, it is [tex]\mu_1 - \mu_2[/tex], and the correct answer is given by option c.

Read this excerpt from "Rikki-Tikki-Tavi by Rudyard Kipling.Darzee was a feather-brained little fellow who could never hold more than one idea at a time in his head; and just because he knew that Nagaina's children were born in eggs like his own, he didn't think at first that it was fair to kill them. But his wife was a sensible bird, and she knew that cobra's eggs meant young cobras later on; so she flew off from the nest, and left Darzee to keep the babies warm, and continue his song about the death of Nag. Darzee was very like a man in some ways.She fluttered in front of Nagaina by the rubbish heap, and cried out, "Oh, my wing is broken! The boy in the house threw a stone at me and broke it. Then she fluttered more desperately than ever.Nagaina lifted up her head and hissed, "You warned Rikki-tikki when I would have killed him. Indeed and truly, you've chosen a bad place to be lame in.
