Is 2.89 rational or irrational
exis [7]

Answer:

Rational

Step-by-step explanation:

<u>Rational numbers:</u>

Rational numbers are such numbers that can be expressed in the form p/q, where the value of q must not be equivalent to 0.

<u>Irrational numbers:</u>

These numbers cannot be expressed in the form p/q, where the value of q must not be equivalent to 0.                                                                                   <u>                                                         </u>

\implies 2.89 = \dfrac{289}{100} \ \ \text{[In} \  \frac{\text{p}}{\text{q}} \ \text{form (\text{q}} \neq 0)]}

Thus, 2.89 is a rational number.

Ase the points (-1,1) and (1, -1) on the graph of y = 2x -3
kondaur [170]

Step-by-step explanation:

y = 2x - 3 \\ plug \: x =  - 1 \\ y = 2( - 1) - 3 =  - 2 - 3 =  - 5 \neq1 \\ hence \: ( - 1, \: 1) \: does \: not \: lie \: on \: the \:  \\ graph \: of \: y = 2x - 3. \\  \\ y = 2x - 3 \\ plug \: x =  1 \\ y = 2 \times 1- 3 =  2 - 3 =  - 1 \\ hence \: ( - 1, \: 1) \:  lie \: on \: the \:   graph \: of \:  \\ y = 2x - 3. \\  \\

hey guys i have everything caught up but in science i have a 96 but a missing project. projects a worth 80 percent of your grade
zvonat [6]

Answer:

No

Step-by-step explanation:

Technically, if you didn't turn anything in then no. If it is truly 80% of your final grade then not turning anything in would drop your grade to an F immediately. Although for a single project to be worth 80% of the entire year's grade seems off. Usually, finals and projects are a large percentage, but are more around the 25% range and not 80%. Otherwise, a student could not do anything the entire year and simply do the project and still pass with a B. That is why the grading system is not usually designed like this.
