What is the slope-intercept form of the linear equation 2x + 3y = 6? Drag and drop the appropriate number, symbol, or variable to each box
Answer:
y = -2/3x + 2
Step-by-step explanation:
2x + 3y = 6
To put it in slope intercept form, move x to the other side:
3y = -2x + 6
Divide each side by 3:
y = -2/3x + 2
So, y = -2/3x + 2 is the slope intercept form of the linear equation
What is the slope of a line parallel to the line whose equation is 5x+y=-9
Answer:
slope = - 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c (m is the slope and c the y- intercept )
Given
5x + y = - 9 ( subtract 5x from both sides )
y = - 5x - 9 ← in slope- intercept form
with slope m = - 5
Parallel lines have equal slopes, thus
The slope of a parallel line to the given equation is m = - 5

Harriet works at the Mint, where new coins are made. Old and fake coins are also destroyed there. Harriet has 10 bags of $1 coins. All 10 bags contain the same number of coins. Harriet knows that nine bags contain only good coins and that one bag contains only fake coins. The fake coins are all about 0.5 gram short. Harriet has forgotten which bag contains the fake coins.
Harriet has a set of scales for weighing like the ones in the illustration. What is the lowest number of times she can weigh bags on the scales in order to find the bag of fake coins?
Answer:
3 times
Step-by-step explanation:
She would have to weigh the fake coins and another bag of real coins to spot a difference, and then she would need to check another bag to see which was correct. Maybe thats right.

Answer:
first and third quadrants
the answer B
Step-by-step explanation:
on the first quadrant x and y are both positive
in the second one x is negative and y positive so -x/y=-1
on the third quadrant x and y are both negative
so -x/-y=1
on the fourth quadrant x is positive and y negative so
x/-y=-1
here, in all cases x and y are taken the same length that's why we take always 1 or -1

RE QUESTION!! ANSWERS NEEDED!!!
Step-by-step explanation:
You divide for the first one. for example, 3/18, u divide it with 3. 18÷3 is 6, so you divide the same the number. so it will be 1/6. so F, is 1.
for the other one, you polt the points and then connect it, but then when it says Stop, you have to stop and start a new a one. lemme show u an example.

Step-by-step explanation:
The length of a rectangle is twice the width. The area of the rectangle is 80 square units. Notice that you can divide the rectangle into two squares with equal area. How can you estimate the side length of each square? Estimate the length and width of the rectangle.
Answer:
Width of the rectangle = 6.325 units
Length of the rectangle = 12.65 units
Side length of the square the 6.325 units.
Step-by-step explanation:
The length of a rectangle is twice the width. The area of the rectangle is 80 square units.
The area of the rectangle = Length × Width
Length = 2W
80 square units = 2W × W
80 = 2W²
W² = 80/2
W² = 40
W = √40
Width of the rectangle = 6.3245553203 units
Approximately = 6.325 units
Length = 2 × Width
= 2 × 6.325
= 12.65 units
• Notice that you can divide the rectangle into two squares with equal area. How can you estimate the side length of each square?
We you divide a rectangle into 2 squares,
The length is divided into two.
Hence, the length of the rectangle = 12.65 units
12.65 units ÷ 2 = 6.325 units.
Hence, the side length of the square the 6.325 units.

Answer:
21Step-by-step explanation:
The number of rectangles and combinations:
1 rectangle = 62 rectangles = 53 rectangles = 44 rectangles = 35 rectangles = 26 rectangles = 1Total
6 + 5 + 4 + 3 + 2 + 1 = 21Now the number of,
Rectangles and combinations are,
→ 1 rectangle = 6
→ 2 rectangles = 5
→ 3 rectangles = 4
→ 4 rectangles = 3
→ 5 rectangles = 2
→ 6 rectangles = 1
Then the total number is,
→ 6+5+4 + 3+2+1
→ 15 + 6 = 21
Hence, total number is 21.

if you flip three coins, the probability of getting three heads is 1/8. Interpret this probability.
The interpretation of the probability is there is a 12.5% chance of obtaining three heads when three coins are flipped
The probability is given as:
[tex]\mathbf{Pr = \frac 18}[/tex]
The above represents the probability of flipping a head three times.
Express as decimal
[tex]\mathbf{Pr = 0.125}[/tex]
Express as percentage
[tex]\mathbf{Pr = 12.5\%}[/tex]
This means that, there is a 12.5% chance of obtaining three heads when three coins are flipped

Solve for H: A = L ⋅ W ⋅ H
H = A times W over L
H = W times L over A
H = L times A over W
H = A over quantity L times W
Answer:
The answer would be
H = A over L times W
Step-by-step explanation:
This is because, when you multiply the L, W, and H you end up getting A. This means that A is the biggest number. We automatically can tell that H is what were looking for so putting those two things together we have this: H = A over ???
The ??? would have to be L times W because those are the only things left and they get multiplied together which in the end leaves us with
H = A over L times w
aka
H=A/LxW

To save money for prom this weekend, Tom is going to walk his neighbor's dog for $6 per hour and wash cars for $7.50 per hour. His mother sid he can work no more than 15 hours to ensure he keeps up with his homework. Tom needs to make at least $75 to cover prom expenses. If d represents the number of hours walking his neighbor's dog and c represents the number of hours washing cars, which system of inequalities represents this situation?
a
\large 6d+7.5c\le15
\large d+c\ge75
b
\large 6d+7.5c\le75
\large d+c\ge15
c
\large 6d+7.5c\ge75
\large d+c\le15
d
\large 6d+7.5c\ge15
\large d+c\le75
Answer:
d + c ≤ 15
6*d + 7.50*c≥ 75
Step-by-step explanation:
Mathematical inequality is that proposition that relates two algebraic expressions whose values are different. It is a proposition of relation between two different elements, either by greater, lesser, greater or equal inequality, or less or equal.
In other words, an inequality is obtained by writing two numerical or algebraic expressions related to any of the symbols>, <, ≥ or ≤.
You know Tom's mom said that he can't work more than 15 hours to make sure he keeps up with his homework. That is, the number of hours walking the neighbor's dog added to the car wash should not exceed 15 hours, that is, it must be less than or equal to that amount. If d represents the number of hours walking your neighbor's dog and c represents the number of hours washing cars, then it is possible to represent this by the following inequality:
d + c ≤ 15 Inequality (A)
On the other hand, you know that Tom needs to earn at least $ 75 to cover the expenses of this weekend's prom. In other words, the money earned by walking dogs added to that earned by washing cars must be equal to or greater than $ 75. If Tom will walk his neighbor's dog for $ 6 an hour and wash cars for $ 7.50 an hour, then $ 6*d is the money earned walking dogs and $ 7.50*c is the money earned from washing cars. So this is represented by the inequality:
6*d + 7.50*c≥ 75 Inequality (B)
Then the system of inequalities that represents this situation is given by the Inequation (A) and the Inequation (B)

1 pack of cigarettes contains 20 cigarettes. Each cigarette smoked is said to reduce a person's life expectancy by 11 minutes. If a person smoked one pack per day for 25 years, how much shorter would their life possibly be? In minutes: In days: In hours: In years: bruh, heaLP
Answer:
Step-by-step explanation:
1 pack per days means 20 cigarettes a days each cigarette reduces life by 11 minutes. which is 220mins per day
25*365*24*60 =13140000mins originally
1) 25 years in minutes will be
reduction of life due to smoking = 220*365*25= 2007500minutes
2)In days
originally = 9125days
after smoking=220/24*60=0.1527*365*25= 1393days are reduced
3)In hours
originally = 219000hrs
reduced life =3.67*365*25= 33488.75hrs
