Twenty times y is at most 100 in interval notation

Mathematics
1 answer:
DiKsa [7]3 years ago
7 0

Answer:

y\in (-\infty ,5]

Step-by-step explanation:

In this problem, we need to write "Twenty times y is at most 100 in interval notation ".

20 times y means, 20y

Atmost means an inequality which is \le

ATQ,

20\times y\le 100

i.e.

20y\le 100\\\\y\le 5

We can also write it as :

y\in (-\infty ,5]

Hence, the required interval notation is y\in (-\infty ,5].

Select all the ordered pairs that are solutions of the inequality
Kaylis [27]

Answer:

The ordered pair solutions are:

C. (1,-3)

E. (2,5)

Step-by-step explanation:

Given inequality:

y

To check from the list of ordered pairs which are the solution of the inequality.

Solution:

In order to check for the solutions to the inequality, we will plugin the ordered pairs in the inequality and check if it holds true. Each ordered pair is in the form (x,y).

Plugging in each ordered pair in the given inequality to find the solutions.

<em>A) (-3,-2)</em>

-2

-2

The above statement can never be true and hence it is not a solution.

<em>B) (3,14)</em>

14

The above statement can never be true and hence it is not a solution.

<em>C) (1,-3)</em>

-3

-3

-3

<u>The above statement is always true and hence it is a solution.</u>

<em>D) (1,6)</em>

6

The above statement can never be true and hence it is not a solution.

<em>C) (2,5)</em>

What is the slope of the line defined by the parametric equations x=-2+4t and y=1+4t ?
LekaFEV [45]

Answer:

The value of slope m = -1

Step-by-step explanation:

x = -2 + 4t

and y = 1 + 4t

Solving the both equations

x +2 = 4t

=> t = (x+2)/4     eq(1)

y-1 = 4t

=> t = (y-1)/4      eq(2)

Putting eq(1) = eq(2) as left hand side of both equations are same

(x+2)/4 = (y-1)/4

Cross multiplying

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

4x + 8 = 4y -4

4x +4y = -4 -8

4x + 4y = -12

4(x+y) = -12

x+y = -12/4

x+y = -3

y = -x -3

The slope intercept form of line is:

y = mx + b

where m is the slope. Comparing with y = -x-3

The value of slope m = -1
