Which is a solution to the equation-6x+y=-4

a (1, 2)

b (1, -10)

c (1, -4)

d (2,-8)

The best way to solve this problem would be by plugging each of the choices into the equation and seeing which works:

A:

6(1)+2=-4

6+2=-4

8≠4

B:

6(1)-10=-4

6-10=-4

-4=-4

C:

6(1)-4=-4

6-4=-4

2≠-4

D:

6(2)-8=-4

12-8=-4

4≠-4

The answer is B (1, -10).

Hope this helps!!

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
