Answer:
D
Step-by-step explanation:
f(-1) = -5, so C is incorrect
f(0) = -1, so D is correct
Yes your answer is correct
Step-by-step explanation:
1) Add 5x and 3x.
Now you have 8x = 5x + 15/2
2) Subtract 5x from the right side of the equation.
(You also do this to the left side)
Now you have 3x = 15/2
3) Now we want the value of x not 2 or 3x, so we will need to divide 3x by 3 to get the value of x.
3x/3 = 15/2 /2 (If the fraction divided by 3 looks confusing you can convert it into a decimal)
So you would have 3x/3 = 7.5/2
3x/3 = x
7.5/3 = 2.5
<h2>
x = 2.5</h2>
Hope this helps !

Answer:
b) 5
Step-by-step explanation:
6+10=16
40 times 2 = 80
80 div by 15 = 5
Answer:
C
Step-by-step explanation:
✔️First, solve for r:
r/2 ≤ 3
Multiply both sides by 2
r/2 × 2 ≤ 3 × 2
r ≤ 6
This implies that possible value of r is equal to 6 or less than 6.
Graphing this on a number line, the line with a shaded circle, indicating that 6 is included, starts at 6 and points to the left.
This indicates that value of r ranges from 6 and below.
The graph is C.
