Answer: 2
2x-7=11 X=9 set up the up the negative portion of solutions Set up the negative portion of the 2x - 7= - 11 x= -2 and then x = 9,-2
Step-by-step explanation:
Answer:
at most 92
Step-by-step explanation:
Let x represent the smallest of the two consecutive integers. Then their sum is ..
(x) + (x+1) ≤ 185
2x ≤ 184 . . . . . . . simplify, subtract 1
x ≤ 92 . . . . . . . . . divide by 2
The smallest integer is at most 92.
So first you have to find the perfect square that matches up with x^2 + 6x
so half of 6, and square it. your perfect square is 9
x^2 + 6x + 9 = 7 + 9
then, condense the left side of the equation into a squared binomial:
(x + 3)^2 = 16
take the square root of both sides:
x + 3 = ± √16
therefore:
x + 3 = ± 4
x = - 3 ± 4
so your solution set is:
x = 1, -7
Answer:
<h2><u><em>
x = (y-3)/4</em></u></h2>
Step-by-step explanation:
Y= 4x+3 make x the subject
4x = y - 3
x = (y-3)/4
Answer:
x+2 is the lowest turn
Step-by-step explanation:
2x+4 can be simplified into x+2
