i think the answer to this question is $3.06
plz correct me if im wrong
Answer:
A, D
Step-by-step explanation:
for this table:
x 0 5 10 15 20 25 30 35 40
f(x) 5 6 7 8 9 10 11 12 13
A, assuming it's supposed to say f(5)=6, is true since 5 in x corresponds to 6 in f(x)
B is false, since the domain would be the set of all numbers in x, since domain corresponds to input (x) and range corresponds to output (f(x))
C is false, the range is not all real numbers since it is a defined set of numbers
D is true, since 15 in x corresponds to 8 in f(x)
Therefore, A and D are true
Y = cube root of 27
another answer is
<span>y equals square root of 27 divided by 3
Provided it is </span><span>square root of (27 divided by 3)
</span>
Not sure what standard form is, but I can solve for x
so I'm assuming that x2 means x squared or x^2 so
x^2+7x+12=0
since it equals zero, if we can factor it, then
if we have xy=0 then x and/or y=0 so
to factor x^2+7x+12
find what 2 numbers multiply to get 12 and add to get 7 so
12=2 times 2 times 3 or 2 times 6 or 1 times 12 or 3 times 4
the numbesr are 4 times 3 so
x^2+7x+12
facotrs out to
(x+4)(x+3) so
x^2+7x+12=0
(x+4)(x+3)=0
set each to zero
x+4=0 and x+3=0
x+4=0
subtract 4 form both sides
x=-4
x+3=0
subtract 3 from both sides
x=-3
x=-4 or -3
The value of expression without the negative exponent is,
⇒ 2/x⁴
What is Rule of exponent?
The rule of exponent is defined as;
aⁿ = 1/a⁻ⁿ
Now, The expression is given as;
2x⁻⁴
It can be rewrite as;
2x⁻⁴ = 2 / x⁴
Hence, The value of expression without the negative exponent is,
⇒ 2/x⁴
