Hey there,
Ok so we need to put this into slope-intercept form so we can find the slope eaisly, (y=mx+b)
If we move x to the right side we are left with,
2y=-x-3
Next we divide by 2 to free up the y,
y=-1/2x-3/2, this is now in y=mx+b form. Making the slope -1/2
Hope this helped!
Answer: 2 3/4 or 2.75
Step-by-step explanation:
The population of Gilbert increased by 275%. The equivalent to 275% will be:
To express as fraction and decimal, we divide 275 by 100.
= 275/100 = 2 3/4 as fraction
2 3/4 = 2 + (3/4 × 100)
= 2 + 0.75 = 2.75
275% = 2 3/4 or 2.75
2,400,000 is my answer (: I calculated it
Answer:
see explanation
Step-by-step explanation:
Expand the right side and then compare like terms with the left side.
(q + 2 )²
= q² + 4q + 12
= q² + 12 + 4q
Compare like terms with 28 + p
Comparing the terms gives
p = 4q
and comparing the constant terms gives
q² + 12 = 28 ( subtract 12 from both sides )
q² = 16 ( take the square root of both sides )
q = ± = ± 4
Hence
p = 4q = 4 × ± 4 = ± 16
