Answer:
Option C. Anna and Sara
Step-by-step explanation:
<u><em>The complete question in the attached figure</em></u>
Let
h ----> the minimum height h in inches necessary to ride a certain roller coaster
we have

The solution for this inequality is the interval [48,∞)
so
The value of h must be greater than or equal to 48 inches
<u><em>Verify who can ride the roller coaster</em></u>
1) Miguel 42 in
substitute the value of h in the inequality
----> is not true
therefore
Miguel can't ride the roller coaster
2) Patrick 45 in
substitute the value of h in the inequality
----> is not true
therefore
Patrick can't ride the roller coaster
3) Anna 48 in
substitute the value of h in the inequality
----> is true
therefore
Anna can ride the roller coaster
4) Sara 52 in
substitute the value of h in the inequality
----> is true
therefore
Sara can ride the roller coaster
Answer:
d)
true
Step-by-step explanation:
- x - 4y = - 10
x + 4y - 10 = 0
a)
3 + 4×2 - 10 = 0
3 + 8 - 10 = 0
11 - 10 ≠ 0 (false)
b)
- 3 + 4×3 - 10 = 0
12 - 3 - 10 = 0
12 - 13 ≠ 0 (false)
c)
false
d)
true
Step-by-step explanation:
x intercept=(-1,0) because the graph is passing this point on the x axis
y intercept=(0,-3)
P=S1+S2+S3
P=2.3x+14+2x-0.2x+15
P=4.1x+29
The answer is the first one
Hope this helps
