Please help, 5 (y + 2/5) = -13. Y=?

Answers

Answer 1

Answer:

y = -3

Step-by-step explanation:

5y + 10/5 = -13 (distribute 5)

5y + 2 = -13 (simplify fraction)

5y = -15 (subtract 2 from both sides)

y = = -3 (divide 5 from both sides)

Checked worked:

5 ([-3] +2/5)

-15 + 10/5

-15 + 2 = -13

y = -3

Which of the following statements is NOT true?
1) A well-designed experiment is the only legitimate way to establish a cause-and-effect relationship between two variables.
2) We can use results from an observational study to test a claim about a population. 3) When an observational study has a large sample and follows people for many years, we can use the results to establish a cause-and-effect relationship between two variables.
4) When many observational studies together meet specific criteria, the results can provide varying degrees of evidence for a cause-and-effect relationship between two variables. But we should be cautious in interpreting such results.

5-37. Richard's strategy for changing a percent to a decimal is to put the decimal point in front of the percent
number. An example of his work is shown at right. Do you agree with Richard's method? Explain your reasoning.
8%=0.8
80%=0.80
800%=0.800

Answers

9514 1404 393

Answer:

Step-by-step explanation:

The percent symbol (%) is a shorthand way to write "divided by 100" (/100). The percent can be changed to a decimal by making that substitution.

8% = 8/100 = 0.08

80% = 80/100 = 0.80

800% = 800/100 = 8.00

Effectively, the change to a decimal is made by moving the decimal point two places to the left. Richard's strategy only works if the percentage has 2 digits left of its decimal point. It does not work in the general case.

now follow order of operations (Parenthesis, exponents, multipication-division left to right, etc.)

5*2=10

10^4=10000

so the answer would be

10000 if y is 2

Answer:

10,000

Step-by-step explanation:

First, let's do the brackets (because of PEMDAS). We know that y = 2, so we multiply 2 and 5 to get 10. Now, we have to solve 10^4. To get 10^4, multiply 10 by itself four times. That gets us 10,000.

Triangle ABC has A(-3,6),B(2,1), and C(9,5) what the length of side AB? What the length BC what the length AC and what ABC

Answers

Answer:

AB = 5√2

AC = √145

BC = √65

Step-by-step explanation:

Using the formula for calculating the distance between two points

D = √(x2-x1)²+(y2-y1)²

For AB A(-3,6),B(2,1),

AB = √(2+3)²+(1-6)²

AB = √(5)²+(-5)²

AB = √25+25

AB = √50

AB = 5√2

For AC A(-3,6) and C(9,5)

AC = √(9+3)²+(5-6)²

AC = √(12)²+(-1)²

AC = √144+1

AC = √145

For BC B(2,1), and C(9,5)

BC = √(9-2)²+(5-1)²

BC = √(7)²+(4)²

BC = √49+16

BC = √65

Since All the sides are difference, hence triangle ABC is a scalene triangle

The slope of the line tangent to the curve 3x^2-2xy+y^2=11 at the point (1, -2) is ?

Answers

Given :

A curve : 3x² - 2xy + y² = 11

To Find :

The slope of the line tangent to the curve 3x^2-2xy+y^2=11 at the point (1, -2).

Solution :

Differentiating given curve w.r.t x is :

6x - ( 2y + 2xy' ) + 2yy' = 11

Putting the point ( 1, -2) in above equation, we get :

6 - ( 2(-2) + 2y' ) - 4y' = 11

6 - ( -4 + 2y' ) - 4y' = 11

10 - 6y' = 11

6y' = -1

[tex]y' =\dfrac{-1}{6}[/tex]

Therefore, the slope of the line tangent to the given point is [tex]y' =\dfrac{-1}{6}[/tex] .

Answer:

5/3

Step-by-step explanation:

The previous explanation was incorrect because they forgot to differentiate the other side of the equation (11), which would actually become 0, and make the answer 5/3
