Answer:
x=8
y=4
Step-by-step explanation:
y=12-x
-2x+48=32
-2x=-16
x=8
8+y=12
y=4
what should be done first to simplify 18 – 3 + 5 + 2 – 13 + 12 ??
answer:
18 - 3 should be done first.
step-by-step explanation:
this should be done because of PEMDAS. the rule states that between addition and subtraction, you have to go from left to right. therefore, 18-3 comes first when going from left to right.

At the bottom of the screen it says "the equation that models the situation is..."
y-y1 = m(x-x1) — point-intercept form
Given both x1 and y1 = coordinate point.
First we have to find the slope by using rise over run. (y2-y1)/(x2-x1) = m
The slope should be m = -4 then we substitute m-value in point-slope form.
y-y1=-4(x-x1) — new equation. After substituting slope in, we need to find the coordinate point that is part of the graph. You can use any points that are given in the picture. I will use point F or (5,0).
Then we substitute x1 = 5 and y1 = 0 in the point-slope form
y-0=-4(x-5) — point-slope form
y=-4x+20 — slope-intercept form..
How about we change to another coordinate point to substitute in? We can check if these points also give same equation (slope-intercept).
Let's substitute (4,4) in the equation.
y-4=-4(x-4)
y=-4x+16+4
y=-4x+20
Same answer. Meaning that all these points that are shown can be substituted in the equation and get the same slope intercept form.
Therefore, point-slope form for the graph can be
y-4=-4(x-4)
you can also change the coordinate point value.

Answer:
6 : 5
Step-by-step explanation:
The diagram shows you that the boxes have a length (L) to width (W) ratio such that ...
3L = l = 4W
L/W = 4/3
Suppose we call the width of the box 3 units, then its length is 4 units, and we have the crate dimensions ...
l = 4(3) = 3(4) = 12
w = 3+3+4 = 10
Then the ratio l : w is 12 : 10 = 6 : 5.

Step-by-step explanation:
AB = 72 so, then FB would be half of that
so 72 divided by 2 would be 36
5x+1=36 then do substitution
-1 from both sides (from +1 you gotta do the inverse)
5x = 35
divide 5 from both sides because in between 5 and x is a times so the inverse of that is divide
x = 7

Prove that: (12^13–12^12+12^11)(11^9–11^8+11^7) is divisible by 3, 7, 19, and 37. The answer should be like: x^b*3*7*19*37. Also this is my first time asking a question on brainly :)
Answer:
Step-by-step explanation:
Given (12^13–12^12+12^11)(11^9–11^8+11^7),
(12^13–12^12+12^11)(11^9–11^8+11^7) =
[(12^12)12 – 12^12 + 12^11][(11^8)11 – 11^8 + 11^7)
[(12^12)(12 – 1) + 12^11][(11^8)(11 – 1) + 11^7] =
(12^12(11) + 12^11)(11^8(10) + 11^7) =
(12^11(12x11) + 12^11)(11^7(11x10) + 11^7) =
[(12^11)(12x11 + 1)][(11^7)(11x10 + 1)] =
[(12^11)x(11^7)](12x11 + 1)(11x10 + 1) =
[(12^11)x(11^7)](133 x 111) =
[(12^11)x(11^7)](133 x 111) =
[(12^11)x(11^7)](14763) =
[(12^11)x(11^7)](3x7x19x37)
From here, it is clear that the given number is divisible by 3, 7, 19 and 37.

How many different 4-digit PIN codes are there that only include the digits 3, 4, 6, 7, 9 and 2
if each of those digits is only allowed to be used once?
Answer:
840
Step-by-step explanation:
I got the answer from Hegarty
There are different 4-digit PIN codes are there that only include the digits 3, 4, 6, 7, 9 and 2.
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
Numbers to make 4 - digit PIN codes are,
⇒ 3, 4, 6, 7, 9 and 2.
Now,
Since, There are 6 number to choose to make 4 - digit PIN codes.
Hence, Number of different choices to make 4 - digit PIN codes is,
⇒ [tex]^6P_{4} }[/tex]
⇒ 6! / (6-4)!
⇒ 6! / 2!
⇒ 6 × 5 × 4 × 3 × 2! / 2
⇒ 360
Thus, There are 360 choices to make 4 - digit PIN codes.

Answer:
Okay so I’m gonna do a few and list a few examples
In slope intercept form its
y=mx+b
Y= Random Y coordinate (Not that important for now while writing)
m= Slope
X= random x coordinate (not that important for now while writing)
b= Y intercept
SO basically plug it in like that so for the first one
the slope is 1/3 and y-intercept is -1
so
y=1/3x-1
And thats how you do it
leave the y and x
Graphing
So for graphing or fining the equation, first identify the y-intercept
The y-intercept is on the y axis (obviously), and its the number where the line first hits, so for the first one, the y intercept is 3 becuase thats where the first line meets on the Y axis. When identified start doing rise over run, lik just go up and right, if there is no space, dot he opposite, go down and go left or right (depends if the line is rising or falling, you can tell if rising (positive) if the line goes from down to up form left to right , if falling (negative) vice versa, up to down from left to right). And just write the equation after identifying the slope And y-intercept, the x and y don’t matter.
4) y= -1/3x+3 (watch your signs, if falling the slope is automatically negative)
5) y=1/2x+1
6) y=4x-5 (negative y-intercept due to the part where the y meets up with the line, its in the negative side)
(remember to write these equations on the top side of the line

HELP PLEASEEEEE!!!!!!!!!
Please help due ASAP
Show workings please
Step-by-step explanation:
I don't know if this is the right way to so it, but I would do it like this
since a triangle has 180 degrees, the angles all have to add up to 180
So 180 = a + b + c
we already know a, its 95
So 180 = 95 + b + c
now we know the equation for b, so we'll just put it there instead of the b, and since the angles are the same, we should put it instead of c too
180 = 95 + (4x-15) + (4x-15)
now subtract 95 from both sides
85 = (4x-15) + (4x-15)
add the xs and numbers together
85 = 8x - 30
now add the 30 to both sides
115 = 8x
divide by 8
your x is 14 3/8 or 14.375 or 115/8
that's not your angle, that's your x
