Take the x-axis and y-axis and locate the point on the graph. if it is exactly on the line it is a solution. Alternatively you could take the equation in the form of y=mx+b or ay+bx=c and replace the variables with the actual numbers and see if the equation makes sense
Answer:
16/4=4
Step-by-step explanation:
when you divide 16/4 it gives you 4
Answer:
x/8
Step-by-step explanation:
7x/56=x/8
Answer:
p = 1.5 and q = 9
Step-by-step explanation:
Expand the right side then compare the coefficients of like terms on both sides, that is
4(x + p)² - q ← expand (x + p)² using FOIL
= 4(x² + 2px + p²) - q ← distribute parenthesis
= 4x² + 8px + 4p² - q
Comparing coefficients of like terms on both sides
8p = 12 ( coefficients of x- terms ) ← divide both sides by 8
p = 1.5
4p² - q = 0 ( constant terms ), that is
4(1.5)² - q = 0
9 - q = 0 ( subtract 9 from both sides )
- q = - 9 ( multiply both sides by - 1 )
q = 9
Answer:
<u>Step-by-step explanation:</u>
Move all of the x's to one side and everything else on the other.
ax = bx + c
ax - bx = c <em>subtracted bx from both sides</em>
x(a - b) = c <em>factored out the like term of "x" on left side</em>
<em>divided both sides by (a- b)</em>
2x = x + 7 → a = 2, b = 1, c = 7
x = 7
<u>Check:</u>
2x = x + 7
<u>-x </u> <u>-x </u>
x = 7
