Answer:
x=8
Step-by-step explanation:
2(x+4) - 10 =14
distribute the 2 2x +8 -10 +14
simplify 2x-2=14
add 2 2x=16
devide by 2 x=8
Equation of a line;
y=mx+c
m=5
y=5x+c
Replacing for x and y using point (-2, -1)
-1=5(-2)+c
-1=-10+c
c=-1+10
c=9
y=5x+9
Answer:
a) f(x) = (-1/3)x + 8
b) f(x) = (1/3)x + 9
Step-by-step explanation:
f(x) = 1/3x - 8
a) To reflect across the x axis multiply f(x) by -1.
-f(x) = -1 (1/3x - 8)
= (-1/3)x + 8
b) to translate up 17 units add 17 to f(x)
f(x) + 17=
= 1/3x - 8 + 17
= 1/3x + 9
Step-by-step explanation:
8x - 2y + x + x
8x - 2y + 2x
10x - 2y
D 10x - 2y
So D Option is the correct answer
Using Chebyshev's Theorem, it is found that:
At least 75% of the exam scores fall between 76 and 92.
---------------------------
- Chebyshev's Theorem states that the percentage of measures within k standard deviations of the mean is of at least .
- With k = 2, that is, within 2 standard deviations of the mean:
- At least 75% of the measures are within 2 standard deviations of the mean.
84 - 2(4) = 76
84 + 2(4) = 92
- Thus, at least 75% of scores between 76 and 92.
