Determine whether -2 is the solution of the equation.
3x-4=6(x+2)​

answer:

x= (-1/2,0)   y= (0,1)

step-by-step explanation:

answer:

words:   if hakeem puts $59 from each paycheck into savings and he receives 26 paychecks each year, at the end of one year he will have saved 59 times 26, or $1,534 which is $34 over his goal.

equation:   59 x 26 = a or 1534 = a, where a represents hakeem's total amount saved.

model:

59   59   59

step-by-step explanation:

this word problem can be solved in multiple ways as the question indicates, asking for words, and equation and a model.   using the key words and phrases from the problem, we can see that hakeem put $59 from each paycheck into saving and he gets paid every two weeks or 26 times.   because of the words 'each' and 'times', i know that i will have to multiply 59 x 26 to get the total amount that hakeem will save for the year: 26 x 59 = $1,534.  

using words, we can write out the steps to solving the problem.

using an equation, we can solve for a variable.

using a model, we can set up the number paychecks received over the course of a year.

answer: idk

step-by-step explanation:

answer:

any line with slope -4. example: y = -4x + 3

step-by-step explanation:

a perpendicular line has a negative reciprocal slope. if the slope is 4, then the perpendicular slope is -1/4. using the slope intercept form y=mx+b, the line y=1/4x+2 has the slope 1/4. the negative reciprocal slope is the opposite value and the fraction flipped. the perpendicular slope is -4. any line with -4 slope is perpendicular. example: y = -4x +3
