Hello from MrBillDoesMath!
Answer:
(1/8) ( 7 + sqrt(481) )
(1/8) ( 7 - sqrt(481) )
Discussion:
The equation is equivalent to 4x^2 - 7x -27 = 0 (as 3 + 24 = 0), Using the quadratic formula:
x = ( - (-7) +\- sqrt ((-7)^2- 4*4*(-27)) )/ (2*4)
= (1/8) ( 7 +\- sqrt(49+ 432) ) =
= (1/8) ( 7 +\- sqrt(481))

X/4 +5/8 = 3/8
X/4 = 3/8-5/8
X/4 = (3-5)/8
X/4 = -2/8
Multiply both sides by 4 we get
4x/4 = -8/8
X = -1
80%
24/30 = 24 divided by 30
When divided, you get 0.8
0.8 = 0.80
Therefore, the answer is 80%
Answer:
y ≤ -4x + 4
Step-by-step explanation:
slope-intercept form is y = mx + b
the inequality you're given is 4x + y ≤ 4
minus 4x from both sides
you get y ≤ -4x + 4
11 - (-5) = 16. Hope that helped!
