What is the equation in slope – intercept form? 7x + 2y = 14
Answer:
y = - [tex]\frac{7}{2}[/tex] x + 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
7x + 2y = 14 ( subtract 7x from both sides )
2y = - 7x + 14 ( divide all 3 terms by 2 )
y = - [tex]\frac{7}{2}[/tex] x + 7 ← in slope- intercept form
Identify any solutions to the system given below.
2x + y = 5
3y = 15 - 6x

Answer:
j=60
Step-by-step explanation:
j=60
I multiplied. 6*10=60. Then I checked to see if it made sense.
60/6=10. Yes, it is valid.
Answer:
j= 60
Step-by-step explanation:
To find j multiply 6 by 10 which is 60.
When you replace j with 60 it will make sense as 60 / 6 is 10.

( 9 - 3 ) + 20 ÷ 4 Equation
Step 2:
6 + 20 ÷ 4 Subtract
Step 3:
6 + 5 Divide
Answer:
11 Add
PEMDAS:
1. Parenthesis
2. Exponents
3. Multiplication
4. Division
5. Addition
6. Subtraction
Hope This Helps :)
Answer:
The answer is 11.
Step-by-step explanation:
Use PEMDAS
P - Parenthesis
E - Exponents
M - Mulitiplication
D - Divide
A - Add
S - Subtract
So, with that you learn that you solve whatever is in the parenthesis first.
(9 - 3) = 6
Now, divide 20 by 4 which equals 5.
So now the problem is now 6 + 5 which equals 11.
The answer is 11.

Step-by-step explanation:
To make 112 dozen muffins, a recipe uses 312 cups of flour.
How many cups of flour are needed for every dozen muffins made?
Enter your answer in the box as a mixed number in simplest form.
Answer:
Interesting question.
112/12 = 28/3
so 3/28 * 112 = 12
so we multiply 3/28 * 312
936/28
Simplifying we get 33 3/7
[tex]33 \frac{3}{7}[/tex] is the answer.
This is a mixed number with 2 as the whole part and 11/14 as the fractional part.
You may need to drop the ampersand sign and simply say 2 11/14
==============================================
Work Shown:
112 dozen muffins = 312 cups of flour
112/112 dozen muffins = 312/112 cups of flour
1 dozen muffins = 312/112 cups of flour
1 dozen muffins = (39*8)/(14*8) cups of flour
1 dozen muffins = 39/14 cups of flour
1 dozen muffins = (28+11)/14 cups of flour
1 dozen muffins = (28/14+11/14) cups of flour
1 dozen muffins = (2+11/14) cups of flour
1 dozen muffins = 2 & 11/14 cups of flour
Describe in words the translation of X represented by the translation rule T ...?
The vector notation <4, -5> is the same as writing [tex](x,y) \to (x+4, y-5)[/tex] which in my opinion is more descriptive in saying "4 units to the right, 5 units down"
We shift 4 units to the right because of the x+4. Whatever x is, add 4 to it getting x+4. So for instance x = 10 leads to x+4 = 10+4 = 14.
The y-5 is why we shift 5 units down. Eg: y = 37 leads to y-5 = 37-5 = 32.

Someone please help it’s overdue
Answer:
y = 3.2
Step-by-step explanation:
Consider this ratio: y/x = 24/15. This will be used later to isolate the y variable.
Now, replace y/x with 24/15 respectively and y/2 respectively. Solve for Y by simplifying and isolating the y variable.
24/15 = y/2
3.2 = y

King Tut has a castle with one hundred rooms that all have doors labeled 1 to 100 that are shut. His
crazy son Calvin runs around the castle and opens all the doors. Then he runs around the castle and
closes every other door (2, 4, 6, 8, ... 100). Then he runs around the castle and when he comes to
every third door (3,6,9,12,...99) if it is open he closes it and if it is closed he opens it. He then does
the same for every 4th door, then every 5th door and then every 6th door, and so on until then does
it for every 100th door. At the end of this exhausting run clearly door 1 is open, but what other door
are also open? (hint: Grappling would suggest you try using a smaller number like 20 doors and see
if there is a pattern)
