Ascatter plot of data comparing the number of years since holbrook high
school introduced a math club and the number of students participating
contains the ordered pairs (3, 19) and (8, 42). which is the slope-intercept
form of an equation for the line of fit containing those points?

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

answer: 12   they all have at least 28 days
