PLSS HELP will give brainliest!! (if you’re right) is (2,5) a solution to the equation “y=2x+3”

False

Step-by-step explanation:

- The formula to graph a linear equation is y=mx+b. Meaning, 2 is our m and 3 is our b. Since this expression has an equal sign, it is a solid line and shading up. The pair (2.5) is neither on the line or in the solution set.

-In a Texas Instrument (TI-83, 84, or 84 plus) calculator, press the y button and plug in the formula as y=2x+3. After plugging it in, press 2nd then GRAPH. the ordered pair is not the same. In the calculator, the ordered pair is shown as (2,7) and not (2,5). hope this helped :)

correct answer is b. 27/8

step-by-step explanation:

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
