Please Help!!! Find the equation using slope-intercept form
Y-intercept = 4
Point: (2,3)
The equation of the line in slope intercept form is y = - 1 / 2 x + 4.
How to represent equation in slope intercept form?The equation of a line can be represented in slope intercept form as follows:
y = mx + b
where
m = slopeb = y-interceptTherefore, the equation of the line passes through the points (2, 3) and the y-intercept is 4.
Hence,
y = mx + 4
let's find slope using (2, 3)
3 = 2m + 4
3 - 4 = 2m
2m = -1
divide both sides by 2
m = - 1 / 2
Therefore, the equation of the line is y = - 1 / 2 x + 4.

In the lab, Chau has two solutions that contain alcohol and is mixing them with each other. Solution A is 40% alcohol and Solution B is 12% alcohol. He uses 900 milliliters of Solution A. How many milliliters of Solution B does he use, if the resulting mixture is a 24% alcohol solution?
600 mL of solution B and 3(600) = 1800 mL of solution A are used by Chau.
How many letters make up one milliliter?It is equivalent to one thousandth of a liter (1 liter = 1000 milliliters) and is used to measure lesser amounts of liquid. The letters ml or mL are used to represent milliliters. Take note of the following graph, which displays 1000 ml of water. Capacity measurements are made using milliliters. It represents a thousandth of a liter. Alternatively said, a one-liter container might hold 1,000 milliliters. In the metric system, a milliliter abbreviated as ml or mL is a unit of volume. One cubic centimeter, or one milliliter, is equivalent to one thousandth of a liter.Let x = the amount of Solution B used
3x = the amount of Solution A used
Knowing that 13% = 0.13 and 18% = 0.18, we can create the equation shown below:
3x(0.13) + x(0.18) = 342 (Remember that the concentration of pure alcohol is 100%, or 1.00).
0.39x + 0.18x = 342

How many grams of fluorine are required to produce 20.0 grams of FeF3?
Fe + F2 → FeF3
10.1 g of fluorine is required to produce 20.0 grams of FeF3
first, we have to balance the equation:
2Fe+3F₂⇒2FeF₃
The molar mass of FeF₃ is 112.84g/mol. so the num of mol(n) of FeF₃ present in 20.0g of mass is calculated as shown below:
n=20.0g/112.84g/mol
n=0.1772mol
According to the balanced equation on the macroscopic scale, 2 mol of FeF₃ is produced from 3 mol of F₂.
so, 0.1772 mol of FeF₃ is produced from X mol of F₂. where X is calculated as shown below:
X=3 mol/2mol*0.1772 mol
X=0.2658 mol
Hence, 0.2658 mol of F₂ is required. The molar mass of F₂ is 38.0g/mol
so, the mass of 0.2658 mol of F2 is calculated as:
m=0.2658 mol*38.0g/mol
m=10.1g

All the correct expression are;
⇒ 2x + 6 = 2
⇒ 2(x - 4) = 6x
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Now, We have to check all the expression which has x = - 2 as a solution.
So, For first expression;
⇒ 2x + 6 = 2
Put x = -2;
LHS = 2×- 2 + 6
= - 4 + 6
= 2
= RHS
Hence, This expression has a solution x = - 2
For second expression;
⇒ 2(x - 4) = 6x
Put x = -2;
LHS = 2×(- 2 - 4)
= 2 × - 6
= -12
RHS = 6x
= 6×-2
= - 12
Hence, This expression has a solution x = - 2
For third expression;
⇒ 3x + 1/2 = 1/4x + 6
Put x = -2;
LHS = 3×-2 + 1/2
= - 6 + 1/2
= - 11/2
RHS = 1/4x + 6
= 1/4 × - 2 + 6
= - 1/2 + 6
= 11/2
Hence, This expression does not a solution x = - 2.
So, For fourth expression;
⇒ 7 - 3x = 5x + 11
Put x = -2;
LHS = 7 - 3×-2
= 7 + 6
= 13
RHS = 5x + 11
= 5×-2 + 11
= - 10 + 11
= 1
Hence, This expression does not a solution x = - 2.
So, For fifth expression;
⇒ 3x + 15 = 2x + 9
Put x = -2;
LHS = 3×- 2 + 15
= - 6 + 15
= 9
RHS = 2x + 9
= 2×-2 + 9
= - 4 + 9
= 5
Hence, This expression does not a solution x = - 2.

A sequence in mathematics is an enumerated collection of items in which repetitions are permitted and order is important. It has members, just like a set. The length of the sequence is defined as the number of items.
An arithmetic sequence follows a pattern.
Arithmetic progression or arithmetic sequence is a number sequence in which the difference between subsequent terms is constant.
The formula for nth term of the sequence is
Tn = a + (n - 1)d
Where a is the first term, d is the common ratio, and n is the number of terms.

Is the amount of fertilizer made a function of the amount of powder used?
So on solving the provided question, we can say that by equation , y = 5/8x; it makes a vertical line.
What is equation?A mathematical equation is a formula that joins two statements and uses the equal symbol (=) to indicate equality. A mathematical statement that establishes the equality of two mathematical expressions is known as an equation in algebra. For instance, in the equation 3x + 5 = 14, the equal sign places the variables 3x + 5 and 14 apart. The relationship between the two sentences on either side of a letter is described by a mathematical formula. Often, there is only one variable, which also serves as the symbol. for instance, 2x – 4 = 2.
Let y be the number of gallons of fertilizer produced by combining x tsp of fertilizer powder.
5 litres of liquid fertilizer are created by combining 8 tsp of fertilizer powder.
Therefore, the amount of liters of liquid fertilizer produced by combining 1 tsp of fertilizer powder = 5/8

The slope of the line perpendicular to 4x-3y=12 is:
The slope of a line perpendicular to the original line is then the negative reciprocal of 4/3, or -3/4.
What is reciprocal?Reciprocity is a reciprocal exchange of goods, services, or privileges between two parties. It is often used in business transactions and in politics to create beneficial relationships and agreements between parties.
The slope of a line perpendicular to 4x-3y=12 is calculated by finding the negative reciprocal of the slope of the original line. To find the slope of the original line, we need to rewrite the equation in the form y = mx + b, where m is the slope.
In this case, we can rewrite the equation as:
3y = 4x - 12
Yielding the slope of the original line as m = 4/3.

Which transformation will result in an image that is congruent to its pre-image? (x, y) → (2x, −2y) (x, y) → (x, y − 2) (x, y) → (−x, 2y) (x, y) → (−2x, y − 2)
(x,y) --> (x, y-2)
=======================================================
Explanation:
Choice A can be ruled out because of the jump from x to 2x, and from y to 2y. This is a dilation with a scale factor 2. Meaning the preimage enlarges to a bigger image. Specifically the larger image has side lengths twice as long as the smaller preimage. The larger image of course cannot possibly be congruent to the smaller preimage. Congruent figures must have the same corresponding side lengths.
We'll come back to choice B.
Choice C and choice D are ruled out for similar reasoning as choice A was eliminated.
-------------
To summarize the previous section: We ruled out choices A, C, and D. The only thing left is choice B.
Choice B is a translation. The jump from y to y-2 means we shift the point 2 units down. There is no left or right shifting because x stays the same.
For example, the point (5,12) moves to (5,10).
Notice that dilation is not being applied for choice B.
With any geometric translation, aka shifting, the side lengths will remain intact. Something that is 5 units long will stay 5 units long. No amount of shifting will change the distance.
Therefore, a translation preserves distances and lengths. We consider it a rigid transformation. This is why choice B will have the preimage congruent to the image.
