Answer 1

Answer:

r = 0.1

Step-by-step explanation:

Constant proportionality or slope(rate of change) is found by Y divided by X.

1.4(y) ÷ 14(x) = 0.1(slope)

1.6(y) ÷ 16(x) = 0.1(slope)

2.1(y) ÷ 21(x) = 0.1(slope)

Check Work:

14 x 0.1 = 1.4

16 x 0.1 = 1.6

21 x 0.1 = 2.1

Answer 2

Answer:

1/10.

Step-by-step explanation:

The proportionality equation is given to you: [tex]y = rx[/tex]

Next, plug in the given [tex]x[/tex] and [tex]y[/tex] variables into the equation:

When: [tex]x = 14[/tex] & [tex]y = 1.4[/tex]

[tex]1.4 = r(14)\\1.4 = 14r\\(1.4)/14 = (14r)/14\\1.4/14 = r\\r = 0.1[/tex]

When: [tex]x = 16[/tex] & [tex]y = 1.6[/tex]

[tex]1.6 = r(16)\\1.6 = 16r\\(1.6)/16 = (16r)/16\\r = 1.6/16\\r = 0.1[/tex]

When: [tex]x = 21[/tex] & [tex]y = 2.1[/tex]

[tex]2.1 = r(21)\\[/tex]

[tex]21r = 2.1\\(21r)/21 = (2.1)/21\\r = 2.1/21\\r = 0.1[/tex]

r = 0.1 in all of the given, ∴ 0.1 is your answer. Change the decimal into a fraction:

0.1 = 1/10

1/10 is your answer.

What are the roots of the equation x2 + 15x = -57 in simplest a + bi form?

Answers

Answer:

Step-by-step explanation:

Rewrite x2 + 15x = -57 as x^2 + 15x + 57 = 0, in which the coefficients of this quadratic are {1, 15, 57}.

Then the discriminant is b^2 - 4ac  =  225 - 4(1)(57) = -3

                                     

Because the discriminant is negative, we know that the two roots will be complex.  They are:

      -15 ±i√3

Step-by-step explanation:

We can add (15/2)² to complete the square:

  x² +15x +(15/2)² = -57 +(15/2)²

  (x +7.5)² = -0.75

  x +7.5 = ±i(√3)/2 . . . . take the square root

The roots are ...

How would i know if a line on a graph has passed the vertical line test?

Answers

Answer:

The vertical line will only pass the graph line once.

Step-by-step explanation:

For example, I found an example online. The vertical line intersects a circle twice. But on a horizontal squiggly line, it only touches it once. So the circle is NOT a function but the squiggly line IS a function.

Hope this helps!! Brainiest is appreciated!! Happy Holidays!!!!


To use the vertical line test, take a ruler or other straight edge and draw a line parallel to the y-axis for any chosen value of x. If the vertical line you drew intersects the graph more than once for any value of x then the graph is not the graph of a function.

What is the meaning of the the point (4, 22)?

and am I wrong for the first one?

Answers

Answer:

The meaning of (4,22) is Magi had run 4 mike's in 22.5 mins

Have a nice Day , Hope this helped you I would appreciate it if you could mark my answer brainliest

Answer:

No, you are correct for the first one. The meaning of the point (4, 22) is that Magi took 22 minutes to run 4 miles.

Step-by-step explanation:

(4, 22) is written as (x, y) where x is the number of miles Magi ran and y is the number of minutes Magi took.

Thus, when Magi ran 4 miles, she took 22 minutes.

Find the particular solution to y ' = 2sin(x) given the general solution is y = C - 2cos(x) and the initial condition y of pi over 3 equals 1 . (5 points)
-2cos(x)
closeIncorrect
3 - 2cos(x)
checkCorrect
2 - 2cos(x)
-1 - 2cos(x)

Answers

Answer:

[tex]y=2-2\cos(x)[/tex]

Step-by-step explanation:

We have the differential:

[tex]y^\prime=2\sin(x)[/tex]

With the general solution:

[tex]y=C-2\cos(x)[/tex]

And we want to find the particular solution such that it satisfies the initial condition:

[tex]\displaystyle y\Big(\frac{\pi}{3}\Big)=1[/tex]

So, we have:

[tex]y=C-2\cos(x)[/tex]

Substituting π/3 for x and 1 for y yields:

[tex]\displaystyle 1=C-2\cos\Big( \frac{\pi}{3} \Big)[/tex]

Solve for C. Evaluate:

[tex]\displaystyle 1=C-2(\frac{1}{2})[/tex]

Simplify:

[tex]1=C-1[/tex]

Hence:

[tex]C=2[/tex]

Therefore, our particular solution will be:

[tex]y=2-2\cos(x)[/tex]

Hence, our answer is C

Which fraction represents the solution to -6/5/(-3/25) in simplest form?
A. -10
B. -18/125
C. 10
D. 18/125

Answers

D, because you multiply -6 with -3 which is 18, then multiple 5 and 25 which faces you 125.

The fraction represents the solution to (-6/5)/(-3/25) in the simplest form will be 10. Then the correct option is C.

What is Algebra?

Algebra is the study of algebraic expressions, while logic is the manipulation of those concepts.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to answer the problem correctly and precisely.

The fraction numbers are given below.

-6/5 and -3/25

Then the division of the numbers -6/5 and -3/25 will be given by putting a division sign between them. Then we have

⇒ (-6/5) ÷ (-3/25)

⇒ (-6/5) / (-3/25)

⇒ (6/5) x (25 / 3)

⇒ 150 / 15

⇒ 10

The part that addresses the answer for (- 6/5)/(- 3/25) in the most straightforward structure will be 10. Then the right choice is C.

Ellis is making some beef burgers for his friends. His recipe 500g of beef mince and 120g of cheese to make four burgers. He buys 1.5 of mince and 400g of cheese, and makes as many burgers as possible. How much cheese will he have left over

Answers

Given :

Ellis is making some beef burgers for his friends.

His recipe 500g of beef mince and 120g of cheese to make four burgers.

He buys 1.5 of mince and 400g of cheese, and makes as many burgers as possible.

To Find :

How much cheese will he have left over.

Solution :

500 g and 120 g of beef mince and cheese respectively make 4 burgers.

125 g and 30 g of beef mince and cheese respectively make 1 burgers.

Now, we will keep increasing  the ingredients until there is any shortage of any ingredients.

1000 g and 240 g will make 8 burgers.

1500 g and 360 g will make 12 burgers.

1625 g and 390 g will make 13 burgers.

Cheese left is ( 400 - 390 ) g = 10 g.

Therefore, 10 grams of cheese will be left.

Sam opened a savings account with a deposit of $50. Every month after that, he
deposited $20 more. Is this a proportional relationship? Why or Why not?

Answers

Step-by-step explanation:

It is given that,

Sam opened a savings account with a deposit of $50. Every month after that, he  deposited $20 more.

It is not a proportional relationship. As initial amount was $50 and every month he deposited $20 more. The ratio is not constant for the deposited amounts.

To make the relationship proportional, he must start with zero balance and then should have deposited $20 every month.
