Answer:
18
Step-by-step explanation:
(3x^2- 5)(x^2+2) that is the answer
Answer:
y = 2/3x + 4
Step-by-step explanation:
Start off with the linear equation
y = mx+ b
Find the slope with two points:
(3,6), (-6,0)
y2-y1/x2-x1
-6/-9 = 2/3
y = 2/3 x + b
6 = 2 + b
b = 4
y = 2/3 x + 4
The standard form:
The point-slope form:
m - slope
The formula of a slope:
We have the points (6, 1) and (5, 4). Substitute:
<em>use distributive property</em>
<em>add 1 to both sides</em>
<em>add 3x to both sides</em>
If 68 minutes ago it (then) was three times as many minutes past 10 am (now)
x + 68 = 3 ×
×
(120 - x) →
→
x = 73 min
… if 68 minutes ago it (now) was three times as many minutes past 10 am (then)
x = 3 ×
×
[120 - (x + 68)] →
→
x = 39 min
… if 68 minutes ago it (then) was three times as many minutes past 10 am (then)
x + 68 = 3 ×
×
[120 - (x + 68)] →
→
x = 22 min
