Answer:
x = 1
Step-by-step explanation:
One thing that is necessary to learn this is that whatever you do to one side, you must do to the other. If you substract 2, you must substract 2 from both sides.
Here are all the steps:
x - 2 = -3x + 2
x = -3x + 4 (by adding 2 to both sides)
4x = 4 (by adding 3x to both sides)
x = 1 (by dividing both sides by 4)
Hope this helps!
Answer:
[tex]x=1[/tex]
Step-by-step explanation:
Add [tex]2[/tex] to both sides of the equation:
[tex]x-2=-3x+2[/tex]
[tex]x-2+2=-3x+2+2[/tex]
Simplify:
Add the numbers:[tex]x[/tex][tex]-2+2=-3x+2+2[/tex]
[tex]x=-3x+2+2[/tex]
Add the numbers:[tex]x=-3x+2+2[/tex]
[tex]x=-3x+4[/tex]
[tex]x=-3x+4[/tex]
Add [tex]3x[/tex] to both sides of the equation:
[tex]x=-3x+4[/tex]
[tex]x+3x=-3x+4+3x[/tex]
Simplify:
Combine like terms:[tex]x+3x=-3x+4+3x[/tex]
[tex]4x=-3x+4+3x[/tex]
Combine like terms:[tex]4x=-3x+4+3x[/tex]
[tex]4x=4[/tex]
[tex]4x=4[/tex]
Divide both sides of the equation by the same term:
[tex]4x=4[/tex]
[tex]\frac{4x}{4} =\frac{4}{4}[/tex]
Simplify:
Cancel terms that are in both the numerator and denominator:[tex]\frac{4x}{4} =\frac{4}{4}[/tex]
[tex]x=\frac{4}{4}[/tex]
Divide the numbers:[tex]x=\frac{4}{4}[/tex]
[tex]x=1[/tex]
[tex]x=1[/tex]

The equation y =
12 represents a proportional relationship. What is the
constant of proportionality?
A. 12
B. X
C. 1
D. 0
Answer:
The constant of proportionality k = 12
Hence, option A is true.
Step-by-step explanation:
We know that when 'y' varies directly with 'x', we get
y ∝ x
y = kx
Where 'k' is called the constant of proportionality.
In our case,
The given equation is
y = 12x
comparing with the equation y = kx, we can say
k = 12 which is the constant of proportionality.
Therefore, we conclude that:
The constant of proportionality k = 12
Hence, option A is true.
If the cost of electricity increases by 30% by what percentage one should reduce his spend in order that spends on electricity stays the same?
Answer:
That depend on how much you spend on electricity, and how much other spending you do.
For example: If your electric bill is 100 dollars, and it increases 30 percent to 130, that’s 30 extra dollars. If your electric bill is only 50 dollars, it will increase to 65, that’s an extra 15.
What percentage that increase is of your current spending will vary according to how much you spend. If you only spend 30 dollars, then you’ll need to cut all of it, or half of it to offset the increases I mentioned above. That’s a 100 percent or 50 percent reduction.
If you spend 1000 dollars, you’ll only need to cut spending by 3 percent to get that 30 dollars, or 1.5 percent to get the 15 dollars.
It all depends on your specific values, you can’t say “For every xx percent your electric bill increases, you need to cut spending by yy percent.”
for the consumption of X unit let u spends Y
for X - Y cost
for increased 30% means 13X/10 - 13Y/10 cost
extra money is 13Y/10 - Y = 3Y/10
note: hope this helps :)
thus (3Y/10)/ (13Y/10) *100 % = 300 / 13 = 23.07%.

A line through the origin and (10,4) is showin in the standard (x,y) coordinate plane below. The acute angle between the line and the positive x-axis has measure θ.
Answer:
[tex]\cos\theta=\frac{10}{\sqrt{116}}[/tex]
Step-by-step explanation:
To solve this, we can imagine a line drawn directly down from the point (10,4) to the x-axis. This would make a right triangle with length 10 and height 4.
[tex]\cos\theta[/tex] is equal to the length of adjacent leg to the angle divided by the length of the hypotenuse of the triangle. From the picture, we can see the adjacent leg is 10.
We can use Pythagorean's Theorem to find the hypotenuse (let [tex]c[/tex] represent the length of the hypotenuse):
[tex]10^2+4^2=c^2[/tex]
[tex]100+16=c^2[/tex]
[tex]116=c^2[/tex]
[tex]c=\sqrt{116}[/tex]
Thus, we know the adjacent is 10, and the hypotenuse is [tex]\sqrt{116}[/tex]. This means [tex]\cos\theta=\frac{10}{\sqrt{116}}[/tex].
Hope this helps!

Find the orthocenter of a triangle with vertices (−8, 11), (−3, 11), and (−3, −12).
The orthocenter of triangle is at ( , ).
Answer:
( -3, 11)
Step-by-step explanation:
find the equation of the line between points ( -8, 11) and (-3, 11)
y= mx +b , where m is slope snd b is y-intercept
m = (y2-y1)/ (x2-x1) = 11-11/ -8- -3 = 0/ -5 = 0 ( if slope is o is a horizontal line)
y = 0x + b and pick a point to find b
11 = 0*-8 + b so b= 11
y = 11 is the equation of the line between points ( -8, 11) and (-3, 11) and the equation of its perpendicular line is x=-3
the equation of the line between points (-3, 11) and ( -3, -12) is x= -3 and the perpendicular to it is y= 11
so we have a right triangle so the ortho center is at (-3, 11) where the vertex of the 90 degree angle is
What is-26000-(-9500)

PLEASE HELP !! ILL GIVE BRAINLIEST *EXTRA POINTS*..
IM GIVING 40 POINTS !! DONT SKIP :((.
Answer:
[tex]y=-10x+43[/tex]
Step-by-step explanation:
We need to put this line into slope-intercept form, which is [tex]y=mx+b[/tex], where [tex]m[/tex] is the slope and [tex]b[/tex] is the [tex]y[/tex]-intercept.
The slope is rise over run, how much the [tex]y[/tex] value changes for one [tex]x[/tex] value. This can be found with the equation: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] where [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are points on the line. Plugging in the first two points:
[tex]m=\frac{3-13}{4-3}=-10/1=-10[/tex]
We know them that [tex]m=-10[/tex]. This gives us for now [tex]y=-10x+b[/tex].
Now, to solve for [tex]b[/tex], plug in any one of the points (I'll use (3,13)):
[tex]13=-10(3)+b[/tex]
[tex]13=-30+b[/tex]
[tex]b=43[/tex]
This gives us the equation [tex]y=-10x+43[/tex].

The measure of an angle is the degrees between the initial and terminal sides of the angle.
Identify the slope and y-intercept
Answer:
y-intercept: -4, slope: -3/2 or -1.5
Step-by-step explanation:
The point where the line goes through the y axis has y coordinate of -4 so that is the y-intercept.
The line goes down 3 units every 2 units to the right. The slope is rise over run, so that makes the slope -3/2.

The formula P=a+b+c gives perimeter P of triangle side lengths a,b,and c how much greater is perimeter when triangle measures 33yds 56yds and 65yds to a triangle that measures 26yds 49yds and 38yds
Answer:
41 yards greater is the perimeter of 1st triangular field than the perimeter of 2nd triangular field.
First we have to calculate the perimeter of 1st triangle.
Given:
a = 33 yards
b = 56 yards
c = 65 yards
Now we have to calculate the perimeter of 2nd triangle.
Given:
a = 26 yards
b = 49 yards
c = 38 yards
Now we have to calculate which triangle has greater perimeter and how much greater.
Therefore, 41 yards greater is the perimeter of 1st triangular field than the perimeter of 2nd triangular field.
Step-by-step explanation:
(154-113)
41 yards bigger
Answer:
41 yds
Step-by-step explanation:
33+56+65=154
26+49+38=113
154-113=41 yds
