you multiply 11 to both sides of the equation so your answer is 176=k

I hope this helped :)

3^4 is 3*3*3*3 so 3*3 is 9 and 9*9 is 81 so 3 to the 4th power is 81

i hope this helped

(x-1)(x+3) to get the values of x you set each part of the problem equal to 0 so x-1=0 and x+3=0 and then you get x by itself so x=1 and x=-3

i hope this helps :)

so with 1/4+1 1/2 you have to make 1 1/2 a fraction which would be 3/2 so now you have the equation 1/4 + 3/2 now you have to find the common denominator which is 4 so now you have 1/4 + 6/4 then you add the numerators of both of the fractions to get 7/4 then you would reduce the fraction to 1 3/4

i hope this helped

so you have to get rid of one variable first to get the value of one. so i multiplied 3a-4b=10 by 4 to get 12a-16=40 and 3b+4a=6 by -3 to get -12a-9b=-18 and added them together to get -25b=22. then you get b by itself and you get b= -0.88. then you go back to the original equations and put the value of b in instead of the variable to get a=2.16 so if a=x and b=y the point of intersection would be (2.16,-0.88) but if b=x and a=y it would be (-0.88,2.16)

hope this helped
