The answer is:  "72" .
______________________________________________
 (input value, or "x")  / 10 = y  = f(x);

When y = 7.2, what is the value of "x" ?


x / 10 = 7.2 ;

x = (7.2) * 10 = 72 .

Step-by-step explanation:

The fast way: Testing the options!

Teacher loving way:

An= d×n + A0

d= A4-A3=A5-A4=A6-A5...= 6

A3= 0 = 6×3 + A0

A0= -18

Then the equation is: An= 6n - 18

Help pls!!!!!!!!!!!!!!!!
Anastaziya [24]

ANSWER.


The correct answer is Option A


EXPLANATION.


The real number

\sqrt{35}=5.916079783


to 9 decimal places.


You can see that the decimals are not repeating, neither will they terminate.



Therefore the real number \sqrt{35} is irrational because, the decimal does not terminate or repeat


Also note that,


\sqrt{35}=\sqrt{5} \times \sqrt{7} .


That is,

\sqrt{35} is a product of two irrational numbers, which still gives an irrational number.

Select all points that are on the line through 0,5
Rus_ich [418]

Answer:

Options (1), (3), and (4)

Step-by-step explanation:

Since, slope of a line passing through two points (x_1,y_1) and (x_2,y_2) is given by,

m = \frac{y_2-y_1}{x_2-x_1}

Therefore, slope of a line passing through (0, 5) and (2, 8) will be,

m = \frac{8-5}{2-0} = 1.5

Equation of line passing through (x', y') and slope 'm' is,

y - y' = m(x - x')

Therefore, equation of a line passing through (0, 5) and slope = 1.5,

y - 5 = 1.5(x - 0)

y = 1.5x + 5

Since, all the points which lie on this line will satisfy this equation.

For (4, 11),

11 = 1.5(4) + 5

11 = 11

Point (4, 11) lies on this line.

Point (5, 10)

10 = 1.5(5) + 5

10 = 7.5 + 5

10 = 12.5

But 10 ≠ 12.5

Therefore, (5, 10) doesn't line on the line.

Point (6, 14)

14 = 1.5(6) + 5

14 = 14

True.

Therefore, (6, 14) lies on the line.

Point (30, 50)

50 = 1.5(30) + 5

50 = 50

True.

Therefore, (30, 50) lies on the line.

Point (40, 60)

60 = 1.5(40) + 5

60 = 65

But 60 ≠ 65

Therefore, (40, 60) doesn't lie on the line.

Options (1), (3) and (4) and the correct options.

Solve for v 17 - 2v = -53solve for v 17-2v=-53
lapo4ka [179]

Hey!

------------------------------------------------

Steps To Solve:

17 - 2v = -53

~Subtract 17 to both sides

17 - 2v - 17 = -53 - 17

~Simplify

-2v = -70

~Divide 2 to both sides

-2v/-2 = -70/-2

~Simplify

v = 35

------------------------------------------------

Hence, the answer is \Large\boxed{\mathsf{v~=~35}}

------------------------------------------------

Hope This Helped! Good Luck!
