Answer:
Both are solutions of x.
Step-by-step explanation:
[tex]x^{2} =49[/tex]
For [tex]x^{2} =f(a)[/tex] the solutions are [tex]x=\sqrt{f(a)} ,-\sqrt{f(a)}[/tex]
[tex]x=\sqrt{49} ,x=-\sqrt{49}[/tex]
[tex]\sqrt{49}[/tex]
Factor the number: [tex]49=7^{2}[/tex]
Apply radical rule: [tex]\sqrt[n]{x^n} =a[/tex]
[tex]\sqrt{7^2} =7[/tex]
=7
[tex]-\sqrt{49}[/tex]
Factor the number: [tex]49=-7^2[/tex]
Apply radical rule: [tex]\sqrt[n]{x^n} =a[/tex]
[tex]-\sqrt{7^2}=7[/tex]

C
The value of x = 2, the length of AB is 13 and BC is 8.
A, B and C are collinear with point B between points A and C.
A___________.__________C
B
AC = 21 , AB = 15 -x and BC = 4 + 2x
As the point, B is the mid-point of the line AC
Therefore we get
AC = AB + BC
AC = 2AB = 2BC
Therefore we get
AC = AB + BC
21 = 15 -x + 4 + 2x
21 = 19 + x
x = 2
As AB = 15 - x
Now put the value of x in the equation, by putting the value of x = 2.
AB = 15 - 2
= 13
BC = 4 + 2x
= 4 + 2×2
= 4 + 4
= 8
Therefore the value of x = 2, and the length of AB = 13 and BC = 8.

People who are illegally parked in downtown Orlando may be issued $15 or $20 parking
tickets. At the end of the week, Officer Bob had issued 41 parking tickets that totaled
$655 in fines. How many $15 tickets and how many $20 tickets did Officer Bob write?
Answer:
$15 tickets - 33, $20 tickets - 8=================================
Let the number of $15 tickets is x and numbers of $20 tickets is y.
Set the system according to given information:
x + y = 4115x + 20y = 655Solve by elimination, multiply the first equation by 20 and subtract the second equation:
20x + 20y - 15x - 20y = 41*20 - 6555x = 165x = 165/5x = 33Find y:
33 + y = 41y = 41 - 33y = 8A plant grows 0.5 inches each week. The plant was 2 inches tall to start. How tall will the plant be after 1 month (4 weeks)?

Step-by-step explanation:
0.5 inches * 4 weeks = 2 inches after 1 month
Then add the 2 inches ( how tall it was before)

A textbook store sold a combined total of 232 physics and math textbooks in a week. The number of physics textbooks sold was three times the number of math textbooks sold. How many textbooks of each type were sold?
The number of physics textbook is 174 and maths textbook is 58.
How to calculate the value?Let the number of maths textbook = x
The number of physics textbook = 3x
Therefore, the expression will be:
3x + x = 232
4x = 232
Divide
x = 232/4
x = 58
Physics textbook = 3x = 3 × 58 = 174
Therefore, the number of physics textbook is 174 and maths textbook is 58.

You have a rock with a volume of 15 cm3 and a mass of 45 g. What's its density?
The formula for density is d = m/v.
d = density
m = mass
v = volume
The volume of the rock is 15 cubic centimeters.
The mass of the rock is 45 grams.
Now just plug these into the formula and solve.
d = 45/15.
45/15 = 3.
The density of the rock is 3 grams per cubic centimeters.
Mass of the rock = 45 g
Volume of the rock = 15 cubic cm
Formula:Density = Mass / Volume
Explanation:By putting the respected values, we get
Density = 45 g / 15 cubic cm = 3 gram/cubic centimeter
Answer:Density of the rock is 3 gram/cubic centimeter.
What are the vertex and range of y = x + 1 + 3?
(0, 4); -
(0, 4); 3 ≤y <∞
(-1,3); -
O(-1, 3); 3 ≤y<∞
The vertex and range of the given function is y = x + 1 + 3 is (0, 4); - (0, 4); 3 ≤ y ≤ ∞.
What is Domain and Range?The Domain of a function is the set of all possible values that a function satisfies.
The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we put an x value in.
Now the given function is,
y = (x + 1) + 3
or, y = x + 4
Now to find the y coordinate of vertex,
put x = 0 in the given function is,
Thus, we get
y = 4
So, the vertex of the given function is
y = x + 1 + 3 is (0, 4); - (0, 4).
Now for range,Put (x + 1) = 0 in the given function
Thus we get,
y ≤ ∞
and y ≥ 3
Thus the range of the given function will be,3 ≤ y ≤ ∞
Thus, the vertex and range of the given function is y = x + 1 + 3 is (0, 4); - (0, 4); 3 ≤ y ≤ ∞

Answer:
99
Step-by-step explanation:
Since the question is or, we only need to answer one. For q, there is of course no answer that will not end the division in decimals. So lets move on to p. The only number that is greater than 20 is 99. Also, 99 is divisible by 5, it will just end in decimals. So the answer is 99.
