The equation y-2/3=-2(x-1/4) is written in point-slope form. What is the equation in slope-intercept form?
Answers
y=mx+b
So we want to get the y isolated on the left side.
First distribute the right side
Then add 2/3 to both sides of the equation to get y by itselft.
y-2/3=-2(x-1/4)
y-2/3=-2x+1/2
y=-2x+(3/6+4/6)
y=-2x+10/6
y=-2x+5/3
Answer: [tex] y=-2x+\dfrac{7}{6}[/tex]
Step-by-step explanation:
The slope -intercept form of a line is given by :-
[tex]y=mx+c[/tex]
The given equation of a line :[tex]y-\dfrac{2}{3}=-2(x-\dfrac{1}{4})[/tex]
To convert it into slope-intercept form , we need to multiply -2 inside the brackets , we get
[tex]y-\dfrac{2}{3}=-2x-\dfrac{-2}{4})\\\\\Rightarrow y-\dfrac{2}{3}=-2x+\dfrac{1}{2}\\\\\Rightarrow y=-2x+\dfrac{1}{2}+\dfrac{2}{3}\\\\\Rightarrow\ y=-2x+\dfrac{7}{6}[/tex]
Hence, the equation in slope-intercept form : [tex] y=-2x+\dfrac{7}{6}[/tex]

the school decided to raise the price lunches by $0.25. Seth buys the school lunch 5 days a week. Write a formula that will help seth determine how much he'll now spend on lunch every week.
p= old price of school lunch
t= total seth pays for lunch each week
Answers
Seth can calculate his weekly lunch expenses with the formula t = 5 x (p + $0.25), where p is the old price and t is the new weekly total.
The question involves creating a formula that Seth can use to determine how much he will spend on lunch every week after an increase in the price.
Let's define the following variables: p for the old price of school lunch and t for the total Seth pays for lunch each week.
If the school decided to raise the price of lunches by $0.25 and Seth buys the school lunch 5 days a week, the new price of each lunch will be p + $0.25.
Therefore, to calculate the total Seth will pay per week, we use the formula: t = 5 x (p + $0.25).
This formula accounts for the new price Seth will pay for lunch each day, multiplied by the 5 days he purchases lunch at school.

The table below shows the steps to prove that if the quadrilateral ABCD is a parallelogram, then its opposite sides are congruent:
Statement: Reasons:
1 AB is parallel to DC and AD is parallel to BC -Definition of parallelogram
2 angle 1 = angle 2, angle 3 = angle 4 -If two parallel lines are cut by a transversal then the alternate interior angles are congruent
3 BD = BD -Reflexive Property
4 triangles ADB and CBD are congruent -If two angles and the included side of a triangle are congruent to the corresponding angles and side of another triangle, then the triangles are congruent by ______?_?_?_______
5 AB = DC, AD = BC -Corresponding parts of congruent triangles are congruent
Which choice completes the missing information for reason 4 in the chart?
AAS postulate
ASA postulate
HL Postulate
SAS postulate
Answers
Step 4 of the proof states that the triangles ADB and CBD are congruent, and the reason is that :
Angle 4 - Side BD - Angle 1 of triangle ADB are respectively equal to
Angle 3 - Side BD - Angle 2 of triangle CBD.
So we have 2 pairs of congruent angles including 2 equal sides of the triangles. This is congruence by ASA postulate.
The correct postulate for reason 4 in the proof chart is the ASA postulate.
To complete the missing information for reason 4 in the proof chart, we need to identify the correct postulate used for congruent triangles.
The given triangles ADB and CBD share the side BD (Reflexive Property), and they have pairs of congruent angles formed by the parallel lines (Alternate Interior Angles Theorem).
Since these triangles have two angles and the included side congruent, the appropriate postulate is the ASA postulate (Angle-Side-Angle).
Therefore, the correct choice is the ASA postulate.

Product A costs her $26.50 She decides mark the product up 30% .How will Emerson charge for product A
Answers
Final answer:
To find the price Emerson will charge for product A with a 30% markup, add the markup to the original cost of $26.50. The final price will be $34.45.
Explanation:
To find the price at which Emerson will charge for product A, you need to add 30% markup to the original cost of $26.50.
To calculate this, first find 30% of $26.50. Multiply $26.50 by 0.30.
30% of $26.50 = $7.95
Next, add the markup to the original cost:
$26.50 + $7.95 = $34.45
Therefore, Emerson will charge $34.45 for product A.

round 96.39 to the tenths place
Answers
Final answer:
To round 96.39 to the tenths place, we increase the tenths digit by one because the hundredths digit is 9, which is greater than 5. The rounded number is 96.4.
Explanation:
To round 96.39 to the tenths place, we look at the digit in the hundredths place (which is 9 in this case). According to the standard rules for rounding numbers, if the first dropped digit is 5 or higher, we round up the last digit that is kept. Since 9 is higher than 5, we will round up. The number 96.39 rounded to the tenths place is 96.4.

Explanation:
(1)
A number is called an irrational number if it can not be written as a simple fraction form. For example [tex]\sqrt{2}, \sqrt{3},\sqrt{5},...[/tex].
If a real number is multiplied by an irrational number then the result is an irrational number.
[tex]\sqrt{49}=7[/tex]
[tex]\sqrt{64}=8[/tex]
Since the result of these square roots are a rational number, therefore [tex]\sqrt{49}, \sqrt{64}[/tex] these are rational numbers and [tex]\sqrt{10}, \sqrt{27}, \sqrt{99}[/tex] are irrational numbers.
(2)
[tex]\sqrt{14} =\sqrt{7} \sqrt{2}[/tex]
[tex]\sqrt{24} =2\sqrt{6}[/tex]
[tex]\sqrt{14} =\sqrt{17} \sqrt{2}[/tex]
[tex]\sqrt{44} =2\sqrt{11}[/tex]
[tex]\sqrt{54} =3\sqrt{6}[/tex]
All the number in the option can not be written in the form of simple fraction, so all the options represents the irrational numbers.
(3)
[tex]0.25=\frac{1}{4}[/tex]
[tex]\sqrt{0.25} =0.5=\frac{1}{2}[/tex]
[tex]\sqrt{0.33} =\frac{\sqrt{33}}{10}[/tex]
Therefore, the number [tex]\sqrt{0.33}[/tex] is an irrational number. The numbers [tex]0.5,\sqrt{0.25}[/tex] are rational numbers.
A fruit basket is filled with 8 bananas, 3 oranges, 5 apples, and 6 kiwis. For every 3 kiwis, there are 4... A) Bananas B) Oranges C) Apples
Answers
The reason why I think this is because..
3/6 and 4/8 are very alike. They both are multiplied by 2 and so 4 times 2 is 8 and that equals to A.
Lol, hope it helps.
Based on the information given, for every 3 kiwis, there'll be 4 bananas.
Number of bananas = 8
Number of oranges = 3
Number of apples = 5
Number of kiwis = 6
Since the question was that there are 3 kiwis, therefore we have to divide the other fruits by 2 as well. In this case, the number of bananas will be:
= 8/2 = 4
Therefore, from the information depicted above, for every 3 kiwis, there'll be 4 bananas.
In conclusion, the correct option is A.

Answer:
Hi!
The correct answer is A. h-625.
Step-by-step explanation:
If you have a dataset listed in ascending order:
[tex]A = \lbrace\ a_1, a_2, a_3,..., a_\frac{n}{2},..., a_n \rbrace[/tex]
[tex]median = a_\frac{n}{2}[/tex]
The value of the mean, if the dataset is even:
The value of that divides a data sample into two halves.The value of the mean, if the dataset is odd:
The average of the two middle values that divide a data sample into two halves.If we substract 625 to each value of the dataset:
[tex]A = \lbrace\ a_1 - 625, a_2 - 625, a_3 - 625,..., a_\frac{n}{2} - 625,..., a_n - 625 \rbrace[/tex]
[tex]median = a_\frac{n}{2} - 625[/tex]
The position of the middle value is the same before the subtraction of 625, then the median would be H - 625.
Use rigid motions to explain whether the triangles in the figure are congruent. Be sure to describe specific rigid motions in your explanation.
Answers
In the case above, ΔDWP is presumed to be congruent to ΔMJS. Rigid motions involved here are translation and rotation.
In translation, you are basically sliding/moving the figure. ΔDWP is moved five (5) units down then one (1) unit to the left. Thereby, coinciding point W of ΔDWP and point J of ΔMJS.
Next rigid motion used is rotation. The figure is simply rotated approximately 90 degrees thereby coinciding all points of ΔDWP to ΔMJS.
To check for congruency by just merely looking on the plane, compare the lengths of the sides of the triangles.
side DW = side MJ = 2 units
side WP = side JS = 4 units
side PD = side SM = 5 units
Therefore, we can say that ΔDWP is congruent to ΔMJS.
In mathematics, congruence of triangles is determined using rigid motions. If one can be made to coincide with the other through translation, rotation, and reflection, then the triangles are congruent.
Explanation:In mathematics, congruence of triangles is determined using rigid motions. Rigid motions include translation, rotation, and reflection. These motions maneuver a figure without altering its shape or size, hence the term 'rigid'.
To determine if two triangles are congruent by rigid motions, you could move one triangle using a combination of these rigid motions to check if it can overlap perfectly with the other triangle. For example, you may need to translate (or slide) the triangle a certain distance in a certain direction, rotate it around a point by a certain angle, and possibly reflect it across a line.
If you can make one triangle coincide with the other through these rigid motions, then the triangles are congruent. Otherwise, they are not congruent. This is basically the idea behind the congruence of triangles through rigid motions.
