4. Which of the following values of x is not in the domain of f (x) = log; (10-2x)?
Answer:
its choice 3) 5
Step-by-step explanation:
We want to see which of the given values of x is not in the domain of f(x) = log(10 - 2x).
The correct option is (3); x = 5.
The domain is defined as the possible inputs of a given function f(x), in this particular case, we have:
f(x) = log(10 - 2x).
Remember that the logarithmic function is only defined for positive arguments, so the values of x that are NOT in the domain of f(x), are these x values such that:
10 - 2x ≤ 0
Solving it for x we have:
10 ≤ 2x
10/2 ≤ x
5 ≤ x
So any value of x equal to or larger than 5 is not in the domain of the given functions, and of the shown options, the only one that is equal or larger than 5 is x = 5, the third option.
So the correct option is the option (3).

Answer:
answer is 3 11/12
Step-by-step explanation:
1 4/6 =10/6
2 1/4=9/4
when adding fractions that are do not share a common denominatour you have to find a common multiple
which in this case is 12
so 9/4 timesed the top and the bottom by 3 gives you 27/12
and 10/6 timesed the top and bottom by 2 gives you 20/12 and then you add the the nominators which is 20+27 which then gives you 47/12 and then to change it back to mixed fraction you will get 3 (wholes) and 11/12 (fraction)

someone please help. we are using the Pythagorean theorem for this question.
for the first question you put the right answer, well done!
for the second question:
the missing side is 14.1 ft.
c²= a²+b²
16.7² = x² +8.9²
278.89= x²+79.21
x²=278.89-79.21= 199.68
we want to find x not x² so we square root x² and that gives us the value for x
x=Square root of 199.68
x= 14.1 ft

Answer:
x=5
Step-by-step explanation:
so it would be 2(5) since 5 is x and that would be 10+y=10.
soo if you're trying to find what + what = 10 it would be zero.
10+0=10.

One of the kinds special triangles you learn about are the Pythagorean triples. These are right triangles with sides in certain ratios. One of them has sides in the ratios 3:4:5.
More generally, this triangle has sides in the ratio 3x:4x:5x
In your triangle, the ratio 8:10 corresponds to 4x:5x with x=2. Therefore, the remaining side is 3x with x=2, so
b=6

f(x) = -⁴/₃x + 6Step-by-step explanation:
f(0) = 6 means y-intercept b = 6
So we have:
f(x) = mx + 6 and f(3) = 2
So:
2 = m×3 + 6
3m + 6 = 2
3m = 2 - 6
3m = -4
m = -⁴/₃
Therefore the function:
f(x) = -⁴/₃x + 6solve. 6,394 ÷ 42 =

A farmhouse shelters 7 animals. Some are horses and some are ducks. Altogether there are 20 legs. How many of each animal are there?
Answer:
3 horses and 4 ducks
Step-by-step explanation:
let h be the no. of horses and d be the no. of ducks
h+d=7
d=7-h
Since horses have 4 legs and ducks have 2 legs,
4h+2d=20
4h+2(7-h)=20
4h+14-2h=20
2h=6
h=3
d=4
If f(x) = 2x2 – 3x + 4, then f(x + 3) is equal to
If function f(x) = 2x2 – 3x + 4, then f(x + 3) is equal to f(x+3)= 2x^2 +9x +13.
Degree of polynomial is two so it will have only two solution
f(a)=0 if x=a
or
f(b)=0 if x=b
so put X=x+3
we will get
2[x+3]^2 - 3[x+3] + 4 = 2x^2 +9x +13
so if f(x+3)= 2x^2 +9x +13
The highest degree of a polynomial's monomials with non-zero coefficients is referred to as the polynomial's degree in mathematics. A term's degree is a non-negative integer and is calculated by adding the exponents of all the variables that occur in it.
The highest exponent of a polynomial's variable is referred to as the polynomial's degree. • A polynomial of degree zero is a constant polynomial. Zero polynomial is the name given to the constant polynomial f(x) = 0.

What is the value of c?
the answer is c=8
hope that helps lolol
Answer: c=8
Step-by-step explanation: All three angles in a triangle add up to 180 degrees so 9c+66+42=180. First add 66 and 42 which is 108, so now you have 9c+108=180. Then subtract 108 from both sides to get 9c=72. Finally, divide each side by 9 to isolate c and you get c=8
