Answer:
–4(x + 3) ≤ –2 – 2x
>>.....-4x -12 ≤ -2 -2x
>> -12 +2 ≤ +2x
>> - 10 ≤ 2x
>> -5 ≤ x............>> x >= -5

Answer:
A, C
Step-by-step explanation:
Rational: Yes, because it is a terminating decimal, and is thus rational.
Real: Yes, all rational numbers are real.
Irrational: No, because it is rational.
Integer: No, because its fractional part is nonzero.
Whole: No, because it is not an integer.
Natural: No, because it is not an integer.
Gven the following table, find the rate of change between f(-4) and f(0)
x -4 -2 0 2 4
f(x) -2 -1 0 1 2
A. -2
B. 2
C. -1/2
D. 1/2
we know that
the rate of change is equal to
(f(b)-f(a))/(b-a)
f(b)=f(0)
f(a)=f(-4)
b=0
a=-4
(f(0)-f(-4))/(0+4)
we have that
f(0)=0
f(-4)=-2
substitute
(0+2)/4
2/4
1/2
therefore
<h2>the answer is the option D</h2>
Answer:
3/4+2/5=13/20
Step-by-step explanation:
The general rule for estimating is to look at the digit to the right of the digit you want to estimate. Estimating or rounding to the nearest whole number means looking at the digit to the right of the decimal. If you see a digit greater than 5, round up, and if it's less than 5, round down.
