Answer:
Step-by-step explanation:
The equation for a linear function found from two given points is: y = mx + b, where m = slope and b = y-intercept. You can find slope from slope formula:
Given points (5, -4) and (-3, 2):
Using the value m = 
and the point (5, -4) for x and y:
y = mx + b
-4 = 5(-3/4) + b
-4 = -15/4 + b
-4 = -3.75 + b
-1/4 = b
Step-by-step explanation:
(a) P = (0.3)(0.2) + (0.5)(0.6) + (0.2)(0.8)
P = 0.52
(b) (0.5)(0.6) = 0.3
P = 0.3 / 0.52
P = 0.58
So you would start at the origin which is 0 then go down one cause of the -1 and right 2 because of the positive 2
Answer:
15.625
Step-by-step explanation:
- (2.5)^3 = 2.5 · 2.5 · 2.5
- 2.5 · 2.5 · 2.5 = 6.25 · 2.5
- 6.25 · 2.5 = 15.625
Therefore, (2.5)^3 = 15.625.
Set up a proportion.
2/3 = 12/x. Cross multiply the proportion.
2x = 36. Solve for x.
x = 18.
