how would i write The difference of three times a number and 4 is -19 in a equation?
Answers
Hi! I'm happy to help!
To solve this, we first have to understand the terms and the way they arrange the equation.
First, we have the difference of ____and_____=. (the "is" after 4 refers to equals)
We will write this as:
_______-_______= ,because difference means subtraction.
For our first blank, we have 3 times a number. Because we do not know this number, we will use a variable.(n) 3 times a number is 3 multiplied by a number. We can just write 3n, because it represent multiplication.
3n-______=
Now, we see the part of the equation after the "and". We just see 4, so we can insert that here:
3n-4=
Now, we see what is shown after the "is".
We just have -19, so we can insert that here:
3n-4=-19
Now, let's solve (not sure if I need to):
To solve for n, we have to isolate it on one side of the equation. To do this, let's cancel out the -4 on the left side of the equation by adding 4 to both sides:
3n=-15
From here, we need to get rid of the 3 next to the n by dividing both sides by 3:
n=-5
So, we write it as 3n-4=-19, and n=-5.
I hope this was helpful, keep learning! :D

Answers
Answer:
The function is decreasing.
Step-by-step explanation:
f(x) = x is the parent function, when you make x negative it decreases rather than increasing. the use of the slope (1/2) doesn't change whether it it increasing or decreasing. as long as the negative sign is in front, it will decrease.

How do I write this in slope intercept form: (-3,-4) and (4,-3)
PLEASE HELP I NEED IT TONIGHT!!!?!?!!!??
Answers
Pick one of the coordinates, I’ll use (-3,-4) as the example.
Coordinates are just numbers plugged in for (x,y).
This means -3 would be your x and -4 would be your y.
So plug these numbers into the equation and you get -4 = m(-3) + b.
M is slope and to find slope, you need to do (y2-y1) / (x2-x1).
In other words, it would be (-3 - -4) / (4 - -3) = 1/7 which is your slope (m).
Now plug that in for m to get the b variable.
-4 = 1/7(-3) + b.
B = -3.57
Your answer is y = 1/7x -3.57

Answers
Answer:
y = -4/5x + 1Step-by-step explanation:
The slope-intercept form:
y = mx + b, where m- slope, b- y-interceptUse point (5, -3) and m = -4/5:
-3 = -4/5*5 + b-3 = -4 + bb = -3 + 4b = 1The line is:
y = -4/5x + 1Answer:
b = 1
Step-by-step explanation:
We know that
y = mx + b
-3 = -4/5 × 5 + b
-3 = -20/5 + b
-3 = -4 + b
-3 + 4 = b
1 = b
