1.)18 = 2(4 + x) ||
2.) 18 = 8 + 2x --- Distribute. ||
3.) 10 = 2x --- Isolate the variable by collecting like terms ||
4.) 5 = x
I'd say A. is a good choice.
Answer:
Step-by-step explanation:
What are the x-intercepts of the graphed function , (-3,0) and (0,1.5), (-3,0) and (1,0), (-1,2) and (1,0), (0,1.5) and (1,0)

Answer:
(-3,0) and (1,0)
Step-by-step explanation:
x-intercepts are the points where the y-coordinate is zero. Based on the options you have listed, they are ...
(-3,0) and (1,0)
_____
We'd need to see the graph to tell where it crosses the x-axis.
0.15 in word form is fifteen hundredths

Answer:
Option C is correct.
f = 2
Step-by-step explanation:
The mean is the sum of variables divided by the number of variables
Mean = (Σfx)/(Σf)
xi | 15 | 17 | 20 | 30 | 10 + f
fi | 4 | 4 | 6 | 5 | 6
Σfx = (15×4) + (17×4) + (20×6) + (30×5) + [(10+f)×6] = 60 + 68 + 120 + 150 + 60 + 6f = (458 + 6f)
Σf = 4 + 4 + 6 + 5 + 6 = 25
Mean = 18.8
18.8 = (458+6f) ÷ 25
458 + 6f = 25 × 18.8 = 470
6f = 470 - 458 = 12
f = (12/6) = 2
Hope this Helps!!!
