Answer:
divide both sides by 2
yes, it is in slope intercept form.
the slope is 1/2
[tex]2y=x+4[/tex]
Divide by 2
[tex]2y/2 = x/2 + 4/2[/tex]
[tex]y=\frac{1}{2} x +4[/tex]
The equation is now in intercept form
The slope of the line is [tex]\frac{1}{2}[/tex]

–5(1 – 5x) + 5(–8x - 2) = -4x – 8x
Answer: x = -5
-------------------------------------------------------------------------------------------------------------
Step-by-step explanation:
Let's solve your equation step-by-step.
−5(1−5x)+5(−8x−2)=−4x−8x
-------------------------------------------------------------------------------------------------------------
Step 1: Simplify both sides of the equation.
−5(1−5x)+5(−8x−2)=−4x−8x
(−5)(1)+(−5)(−5x)+(5)(−8x)+(5)(−2)=−4x+−8x(Distribute)
−5+25x+−40x+−10=−4x+−8x
(25x+−40x)+(−5+−10)=(−4x+−8x)(Combine Like Terms)
−15x+−15=−12x
−15x−15=−12x
-------------------------------------------------------------------------------------------------------------
Step 2: Add 12x to both sides.
−15x−15+12x=−12x+12x
−3x−15=0
-------------------------------------------------------------------------------------------------------------
Step 3: Add 15 to both sides.
−3x−15+15=0+15
−3x=15
-------------------------------------------------------------------------------------------------------------
Step 4: Divide both sides by -3.
−3x /−3 = 15/ −3
x=−5
-------------------------------------------------------------------------------------------------------------
Answer:
x=−5

The way I do these equations is pick one coordinate axis and work with that. So for point K, it goes from X & Y coordinate 1 to 1.5, Point I goes from Y coordinate 2 to 3, and Point J goes from y coordinate 2 to 3 again.
You move left 6 units. You end at (-4, 4). Where did you start?
(you need a coordinate plane)
Answer:
(2,4)
Step-by-step explanation:
Step 1: Understand the question
We know moving left DECREASES the x value and moving right INCREASES the x value.
We need to move 6 units back to the right to get the original coordinate
Step 2: Solve
(-4 + 6, 4)
(2, 4)
Step 3: Therefore statement
Therefore you started at (2, 4)
What is the measure of angle "K" in the triangle pictured

The sum of three consecutive odd integers is 237.what are the integers
Answer:
let the 1st number be x
then second number is x+2
then third number is x+2+2
according to question
sum of three consecutive odd integers is 237.
hence, x+x+2+x+2+2=237
3x+6=237
3x=237-6
3x=231
x=231/3
x=77
therefore 1st integer is 77
2nd integer is 77+2=79
3rd integer is 77+2+2=81
Answer:
77, 79, 81
Step-by-step explanation:
You can represent the equation as follows:
x + x + 2 + x + 4 =237
Combine like terms.
3x + 6 = 237
Subtract 6 from both sides.
3x = 231
Divide both sides by 3.
x = 77
Now, add 2 to 77 to determine the second integer.
77 + 2 = 79
Add 4 to 77 to determine the third integer.
77 + 4 = 81

Write 77^1/10 in the form
n√77 where n is a whole number.
Answer:
[tex]\sqrt[10]{77}[/tex]
Step-by-step explanation:
[tex]77^\frac{1}{10}[/tex] is the same as [tex]\sqrt[10]{77^1} ,[/tex] or simply [tex]\sqrt[10]{77}[/tex]
77^1/10 can be written as [tex]\sqrt[10]{77}[/tex]
what is representation of root?The principal nth root of a is written as n√a , where n is a positive integer greater than or equal to 2. In the radical expression, n is called the index of the radical.
A radical symbol √ is used to represent a square root; the number or expression included within the radical symbol, designated by the letter a below, is known as the radicand.
We have that [tex]77 ^ {1/10}[/tex].
Now, if we have given that √4 we can write it as [tex]\sqrt[2]{4}[/tex]
Again, if we have [tex]7^{1/3}[/tex] we can write it as [tex]\sqrt[3]{7}[/tex]
Similarly we can write 77^1/10 as [tex]\sqrt[10]{77}[/tex]

how can i put this in a graph and a table
Answer:
y=2.49x+24.99
Step-by-step explanation:
y= Total cost of her birthday party
2.49= The price of each ice cream cone
x= The number of ice cream cones she buys
24.99 = The price of the birthday cake
HELP ASAP! Pls and thx! Need help.
Answer:
y = -3x + 22
Step-by-step explanation:
To find m, find the change in y and divide it by the change in x.
For example, the change in y between 19 and 13 is -6. Then determine the change in x. For example, since we determined the change in 19 and 13, let's look at the change in the x coordinates that pair with 19 and 13: 1 and 3. The change in x between 1 and 3 is 2. Now divide the change in y by the change in x: -6/2 = -3. So now we have the equation y = -3x + b, but we still need to figure out b, or the y-intercept. To do this, we need to figure out a pattern in the table to find out what y is equal to when x = 0, the definition of a y-intercept. From just the table alone, it looks like for every 2 units the x-coordinate decreases, the y-coordinates increases by 6. We could also just as easily say that for every 1 unit the x-coordinate decreases, the y-coordinate increases by 3. From this definition, if we look at the coordinate (1, 19), if we were to decrease 1 from the x-coordinate, we would have to increase the y-coordinate by 3 which we can write as (x - 1, y + 3). So, we would get (0, 22). So, when x = 0, y = 22.
