Answer:
\(g(x) = {x}^{2} + 5\)
The graph shows g(x), which is a translation of \(f(x) = x^2\). The function rule for g(x) is \(x^2 + 5\). Hence, g(x) = \(\underline{x^2 + 5}\)
Given, g(x) is a translation of \(f(x) = x^2\)
Let the equation of the function g(x) be
\(g(x) = a(x - h)^2 + k\) ----------(1)
This curve passes through the points (1, 6), (-1, 6) and (2, 9), then their coordinates satisfy the equation:
\(6 = a(1 - h)^2 + k\)----------(2)
\(6 = a(-1 - h)^2 + k\)----------(3)
\(9 = a(2 - h)^2 + k\)----------(4)
Subtract (2) from the first:
\(6 - 6 = a(1 - h)^2 + k - a(-1 - h)^2 - k\)
\(0 = a((1 - h)^2 - (-1 - h)^2)\)
As a \(\neq\) 0,
then \((1 - h)^2 - (-1 - h)^2 = 0\)
\((1 - h)^2 = (-1 - h)^2\)
\(1 - h = -1 - h\),
or \(1 - h = 1 + h\)
As, 1 = -1 is false
h = 0
Then, substituting h = 0 in (2) and (4),
\(6 = a(1 - 0)^2 + k\) ⇒ \(6 = a + k\) ----------(5)
\(9 = a(2 - 0)^2 + k\) ⇒ \(9 = 4a + k\) ----------(6)
Solving (5) and (6) we get,
3a = 3
a = 1
Substituting a = 1 in (5),
6 = 1 + k ⇒ k = 5
Substituting a = 1, h = 0 and k = 5 in equation (1),
\(g(x) = x^2 + 5\)
Therefore, the function rule for g(x) is \(x^2 + 5\).

On thurday, lisa had 5$ in her bank account. she went to target to purchase stickers for her class. each pack of stickers cost 2$
write an inequality that represents s, the number of stickers purchased that resulted in her account ending in -10.
Answers
s = number of sticker packs purchased
x = ending balance in Lisa's bank account
We know that Lisa started with $5 and each pack of stickers costs $2. Therefore, her bank account balance after purchasing s packs of stickers is:
x = 5 - 2s
We also know that her account ended with a balance of -$10. Therefore, we can set up the following inequality:
x = 5 - 2s ≤ -10
Simplifying this inequality:
5 - 2s ≤ -10
-2s ≤ -15
s ≥ 7.5
However, since s represents the number of sticker packs, it must be a whole number. Therefore, the final inequality is:
s ≥ 8
This means that Lisa must have purchased at least 8 packs of stickers in order for her account to end with a balance of -$10.

The sοlutiοn οf the system οf equatiοn is x = 0 and y = 7/3.

Every οne οf the equatiοns in a system οf equatiοns must have a sοlutiοn in οrder fοr the system tο be cοnsistent. This demοnstrates that a set οf values fοr the variables may simultaneοusly satisfy all οf the system's equatiοns and shοw that they are nοt mutually exclusive.
There is nο sοlutiοn tο an equatiοn system that satisfies all οf the equatiοns in the system. This indicates that nο cοmbinatiοn οf values fοr the variables can cοncurrently satisfy all οf the system's equatiοns since they are incοmpatible.
The given equatiοns are:
y = 2/3x + 7/3
-4x+6y=14
Substituting the value of y in the second equation:
-4x + 6y = 14
-4x + 6(2/3x + 7/3) = 14
-2x + 4x + 14 = 14
2x = 0
x = 0
Substitute the value of x = 0 we have:
y = 2/3(0) + 7/3
y = 7/3
Hence, the solution of the system of equation is x = 0 and y = 7/3.

Answers
Answer:
12 is less than 102
Step-by-step explanation:
The options are \(12<102\) or \(12=102\)
12 cannot be equal to 102 as they are not the same number/quantity.
Therefore, 12 has to be less than 102, as 102 is a larger number.
Another way to think about this is imagining a number line. As you go to the left the numbers get smaller, and to the right the numbers increase. If 12 is to the left of 102 on the number line, then it must be less.

How much do the bagels cost and how much do the muffins cost?
Please help
Answers
Answer:
The cost of bagel is $0.8 and that of muffins is $1.25.
Step-by-step explanation:
Let the bagels cost is x and muffins cost is y.
ATQ,
10x+4y=13 ....(1)
5x+8y=14 ....(2) (it should be 14 instead of 4)
Multiply equation (1) by 2 such that,
20x+8y=26 ...(3)
Now subtract equation (2) and (3).
5x+8y-(20x+8y)=14-26
5x+8y-20x-8y=-12
-15x = -12
x = $0.8
Put the value of x in equation (1)
10(0.8)+4y=13
8+4y=13
4y = 13-8
4y=5
y = $1.25
So, the cost of bagel is $0.8 and that of muffins is $1.25.

Volume of cuboid = \(5\frac{5}{8}\) in³
Number of \((\frac{1}{4})\) inch small cubes fitted in the rectangular prism is 360.
Define the term cuboid?A cuboid is a solid three-dimensional object with six rectangular faces that are all at right angles to one another. It goes by the name rectangular prism as well.
Here rectangular prim is a type of cuboid, So we have to find out the volume of cuboid;
The volume of cuboid = length × width × height
Put the values;
Volume of cuboid = \(3\frac{3}{4}\) × 1 × \(1\frac{1}{2}\)
Volume of cuboid = \(\frac{15}{4}\) × 1 × \(\frac{3}{2}\) = \(\frac{45}{8}\)
Volume of cuboid = \(5\frac{5}{8}\) in³
The volume of a cube which is \((\frac{1}{4})\) inch = \((\frac{1}{4})^{3}\) = \((\frac{1}{64} )inch^{3}\)
Number of \((\frac{1}{4})\) inch small cubes fitted in the rectangular prism = Volume of rectangular prism (cuboid) ÷ volume of a cube which is \((\frac{1}{4})\) inch
So, Number of cubes = \(\frac{45}{8}\) ÷ \(\frac{1}{64}\) = 45 × 8 = 360 cubes.
Therefore, Number of \((\frac{1}{4})\) inch small cubes fitted in the rectangular prism is 360.

How do chemical equations work?
These equations employ chemical symbols and formulae to represent chemical reactions. The reactants are represented on the left side of a chemical equation, and the products are on the right.
The reactant entities are presented on the left hand side of a chemical equation, while the product entities are given on the right hand side.
Due to the fact that there are two oxygen atoms on the right side of the equation but only one on the left, the coefficient of H2O will be 2. As of right now, the right side only has two hydrogens whereas the left side has four. Adding a 2 as the H2 coefficient will bring the equation into balance. The equation already has a balanced state, therefore we don't need to adjust the O2 coefficient.

r = (P - B) / Bz
To see why, we can rearrange the original equation as follows:
P = B + Brz
P - B = Brz
(P - B) / Bz = r
Therefore, r = (P - B) / Bz is equivalent to P = B + Brz.
Now let's check the given options:
x = P/Br + 1/r
This equation is not equivalent to P = B + Brz.
r = (P - B) / Bz
This is the correct equation that is equivalent to P = B + Brz.

What is a right-angle triangle?It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.
According to the hypotenuse-leg (HL) principle, a right triangle is harmonious if each of its third side and legs are congruent with its equivalent hypotenuse and legs in another right triangle. The HL theorem proves that these triangles are identical.
From the graph, the equation is given as,
x = a² / h ....1
b - x = c² / h .....2
From equations 1 and 2, then we have
x + b - x = a² / h + c² / h
b = (a² + c²) / h
h = (a² + c²) / b
