Answer: 2.
Step-by-step explanation: Both lines intersect each other 2 times.
Answer: 37
Step-by-step explanation:
(1,10)(-3,2)
slope = (2-10) / (-3-1) = -8/-4 = 2
y = mx + b
slope(m) = 2
(1,10)...x = 1 and y = 10
now we sub and solve for b, the y int
10 = 2(1) + b
10 = 2 + b
10 - 2 = b
8 = b
equation is : y = 2x + 8.....or 2x - y = -8
Answer:
Approx. 59% increase.
Step-by-step explanation:
Today - 221
Yesterday - 139
difference (today - yesterday) = 82
How to find percent:
((part)/(whole)) = ((x)/(100))
In this case, the part is the difference, and the whole is the value of an item yesterday, so the equation is:
82/139 = x/100
cross multiply
8200 = 139x
Inverse operations
8200 = 139x
/139 /139
8200/139 = x
approx. 59 = x
Answer:
-0.53, 2.53 to the nearest hundredth.
Step-by-step explanation:
3x^2 - 6x - 4 = 0
3(x^2 - 2) - 4 = 0
3 [ ( x - 1)^2 - 1] = 4
3(x - 1)^2 - 3 = 4
3(x - 1)^2 = 7
(x - 1)^1 = 7/3
x - 1 = +/- √(7/3)
x = +/- √(7/3) + 1
x = 2.53, -0.53.
