The formula y-y1 = m(x-x1) is the point-slope form of the equation of a lie where m is the slope of the line and (x,y) and (x1,y1)are points of the line. Solve the equation for m, and find slope of a line that includes the points (4,-2) and (5,0)

Answers

Answer 1

Y - y1 = m(X - X1)

m = Y - y1/X - x1

m = -2 - 0/4 - 5

m = -2/-1

m = 2.

The slope of the line is a positive one, where m = 2.

Answer 2

Answer:

m=2

Short Answers:

Answer for part A: Definition of perpendicular
Answer for part B: Right Angle Congruence Theorem
Answer for part C: Reflexive Property of Congruence
Answer for part D: Definition of Midpoint
Answer for part E: [tex]\triangle SXR \cong \triangle TXR[/tex]
Answer for part F: CPCTC

-------------------------------------------------------------

Explanations:

Part A:

We are given that [tex]\overline{RX} \perp \overline{ST}[/tex] which means, in english, "line segment RX is perpendicular to line segment ST"

By the very definition of perpendicular, this means that the two line segments form a right angle. This is visually shown as the red square angle marker for angle RXT. Angle RXS is also a right angle as well.

---------------------
Part B:

The Right Angle Congruence Theorem (aka Right Angle Theorem) is the idea that if we have two right angles, then we know that they are both 90 degrees so they must be congruent to one another.

---------------------
Part C:

Any line segment is congruent to itself. This is because any line segment will have the same length as itself. It seems silly to even mention something so trivial but it helps establish what we need for the proof.

---------------------
Part D:

We are given "X is the midpoint of segment ST" so by definition, X is in the very exact middle of ST. Midpoints cut segments exactly in half. SX is one half while TX is the other half. The two halves are congruent which is why SX = TX

---------------------
Part E:

Writing [tex]\triangle SXR \cong \triangle TXR[/tex] means "triangle SXR is congruent to triangle TXR". These two triangles are the smaller triangles that form when you draw in segment RX

Side Note: SAS stands for "side angle side". The angle must be between the two sides. The pairing RX and RX forms one of the 'S' letters (see part C), while the pairing SX and TX forms the other 'S' (see part D). The angles between the sides are RXS and RXT (see part B).

---------------------
Part F:

CPCTC stands for "Corresponding Parts of Congruent Triangles are Congruent"

It means that if we have two congruent triangles, then the corresponding parts are congruent. Back in part E, we proved the triangles congruent. For this part, we look at the pieces RS and RT (which correspond to one another; they are the hypotenuse of each triangle). They are proven congruent by CPCTC

If CPCTC is an odd concept to think about, then try thinking about something like this: you have two houses which are completely identical in every way. We can say that those two houses are congruent. If the houses are identical, then surely every piece that makes up the house is identical to its corresponding piece to the other house. For example, the front door to each house is both the same size, shape, color, made of the same material, designed in the same pattern, etc. So the two doors are congruent as well.

A cleaner recommends mixing 1½ cup of cleaner for every 12 cups of water. What is the ratio of cleaner to water in simplest form?

1/8

2/3

1/2

7/8

Answers

1/8, because 3/2 divided by 12 is 1/8

we know that

To find the ratio of cleaner to water

Divide the total cups of cleaner by the total cups of water

In this problem we have

total cups of cleaner------> [tex]1\frac{1}{2}[/tex]

convert to an improper fraction

[tex]1\frac{1}{2}=\frac{1*2+1}{2}= \frac{3}{2}[/tex]

total cups of water------> [tex]12[/tex]

Find the ratio

[tex]\frac{(3/2)}{12}= \frac{3}{24}= \frac{1}{8}[/tex]

therefore

the answer is

[tex]\frac{1}{8}[/tex]

Jeremy has 144 marbles. He gives half to Marsha. Then he gives half of what he has left to Sam. He shares in the same way with two more friends. Write the terms that shows the number of marbles Jeremy has.

Answers

Hey!

So, If you want to figure out how much marbles Marsha gets, you first divide 144 by 2. And that equals 72. So Marsha gets 72. THEN, Halve goes to Sam so Sam gets halve of 72. And halve of 72 is 36.

SO MARSHA GETS 72 MARBLES JEREMY GETS 36 AND SAM GETS
36.

Yeah Marsha gets 72 marbles and Jeremy gets 36 and Sam gets 36

there are 156 students in 6 different classrooms. What is the ratio of students that classrooms? If there are 80 boys what is the ratio of boys to girls?

Answers

156-80=numb of girls
numb of girls: 76

Ratio of boys to girls=80:76
=20:19

Ratio of students in classrooms= 156:6
=26:1

(assuming that each classroom has the same number of students)

The easiest way to find out ratios is to divide the total (in this case, students) by the divider (in this case, the classrooms).

156 ÷ 6 = 26

The ratio of students to classrooms is 26 students per classroom, or 26 : 1.

In this case, you need to figure out how many girls there are first.

156 - 80 = 76

Because you don't want to end up with a decimal, you need to find the GCF.

The factors of 76 are: 1, 2, 4, 19, 38, 76
The factors of 80 are: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

Your GCF is 4, which is number you divide your total number of boys and total number of girls by.

80 ÷ 4 = 20
76 ÷ 4 = 19

The simplest ratio of boys to girl is 20 boys for every 19 girls, or 20 : 19

Divide. −24/7 please help

Answers

-24/7 = -3.42857

positive divided by positive = positive

negative divided by negative = positive

positive divided by negative = negative

negative divided by positive = negative

hope this helps

To divide -24 by 7, divide 24 by 7 to get 3.4286 and then apply the sign, resulting in -3.4286 as the answer.

The student's question involves the arithmetic operation known as division. To divide
-24 by 7, you would perform the division as you would with positive numbers, then apply the sign of the numbers. Since one number is negative and the other is positive, the result will be negative. Performing the division: 24 divided by 7 equals approximately 3.4286. Since
24 is negative, the result is -3.4286. When dividing by a single digit, you don't necessarily need to apply long division; instead, you can estimate how many times 7 fits into 24.
Remember that division by powers of 10 involves moving the decimal point. However, that's not applicable here since 7 is not a power of 10.

a recipe calls for 1 1/2 cups of flour, 3/4 cups of white sugar, and 1/3 cup of brown sugar the recipe makes 6 servings.

(a) how many total cups of flour are there per serving? show your work

(b) how many total cups of sugar (white and brown) are there per serving?show your work

(c) supposed you modify the recipe so that it makes 9 servings. How much more flour do you need for the modified recipe than you need for the original recipe?Show your work

Answers

Answer:

(a) 0.25 cups of flour

(b) 0.18 cups of sugar

Step-by-step explanation:

The recipe requires 3 amounts of ingredients to make 6 servings. The following is needed:

1. 1 1/2 cups of flour

2. 3/4 cups of white sugar

3. 1/3 cups of brown suger

a) The total cups of flour per serving can be determined by dividing the flour needed for 6 servings by 6:

[tex]=1.5/6=0.25[/tex]

0.25 cups of flour is needed per serving

b) The total cups of brown and white sugar can be determined by divided both quantites by 6 servings.

For brown sugar = 0.75/6 = 0.125 cups of brown sugar

For white sugar = 0.333/6= 0.0555≈0.055 cups of white sugar

Total amount of sugar = brown sugar + white sugar = 0.125+0.055=0.18 cups of sugar

c) If we can make 9 servings we can determine the the percentage of more servings and the amount of flour for the modified recipe.

The percentage change of recipes = ((9-6)/9)*100=33.33%

Therefore the new amount of flour needed is:

[tex]1.5*0.3333+1.5=2[/tex]

Therefore we need 2-1.5=0.5 cups more flour than the original recipe
