Match each inequality with the correct solution.
1 answer:
Answer:
a. and iii
b. and i
c. and iv
d. and ii
Step-by-step explanation:
a. x + 12 > 15 = x > -2
- 12 - 12
x > 3
2( x = 3)
-3x > 6
/-3 /-3
x > -2
b. 4x + 12 < 20 = x <2
- 12 - 12
4x < 8
/4 /4
x < 2
c. -8x < 16 = x > -2
/ -8 /-8
x > -2
d. 55 < 35 + 10x = x > 2
-35 -35
20 < 10x
/10 /10
2 < x = x > 2
Hope that helps!

<h3>How to graph the function?</h3>The equation of the cosine function is given as:
f(x) = cos(x) - 3
The above function is a cosine function, and the parent function of the cosine function is
f(x) = cos(x)
This means that the function f(x) = cos(x) is translated 3 units down to get the function f(x) = cos(x) -3
Next, we plot the graph of the function f(x) = cos(x) - 3
