Answer:

no solution

Step-by-step explanation:

3(x-2) = 3x-2  

x(3) -2(3) = 3x-2

3x -6 = 3x - 2  (subtract 3x from both sides)

-6 = -2

it is obvious that this is a false statement  (-6 is obviously not equal to -2)

hence this equation has no solution.

We can solve or simplify the equation to find if an equation has one solution, no solutions, or infinitely many solutions.

3(x-2) = 3x-2

Use the distributive property on the left side of the equation

3x-6=3x-2

Subtract both sides by 3x

3x-3x-6=3x-3x-2

-6=-2

Realize how weird our final output is? -6 does NOT equal -2. Since there's no way we could've solved for x and the final output isn't true, this equation has no solutions.

This means that the graph of lines are parallel in the coordinate plane and never intersect.

Let me know if you need any clarifications, thanks!

A vendor at the State Fair has learned that, by pricing his deep fried bananas on a stick at $1.00, sales will reach 82 bananas
Tasya [4]

Answer:

Y=-40x+122

Step-by-step explanation:

hello

Due to the nature of the data, it is most convenient to model this problem as a linear function.

To solve this problem we must use the equation that defines a line, then start assigning the corresponding values

y1=82bananas per day

X1=1 dolar

y2=52bananas per day

x2=1.75dolar

line ecuation

y − y 1 = m(x − x 1 )

where

m=slope=\frac{y2-y1}{x2-x1} =\frac{52-82}{1.75-1}=-40

solving:

Y-82=-40(x-1)

Y=-40x+40+82

Y=-40x+122

let's try the result!

Price =1dolar

Y=-40(1)+122=82bananas per day

Price=1.75dolar

Y=-40(1.75)+122=52bananas per day

PLEASE EXPLAIN TOO SO I CAN SOLVE OTHER SIMILAR ONES.

Answer: x = 30' , y = 45'

hope this helps

Step-by-step explanation:

U is 90' it's a right triangle

well simple VRT you already know 2 angles which is 60' and 90'

R = 60'

V = 90'

T = x

you know that a triangle = 180'

so you do

180 - 60 - 90 = x

30 = x

if you want to do y

then you already know that U is 90' on both sides.

since you also know S,

S = 45'

U = 90'

V = y

180 - 90 - 45 = y

45 = y

Solve the equations. 2.5x−3.67=1.52
aleksklad [387]
Our current equation is:
2.5x -3.67 = 1.52.
To solve for x, we need to get x by itself and then simplify what we can from there.
2.5x -3.67 = 1.52
Add 3.67 to both sides to get 2.5x by itself.
2.5x = 5.19 is now our new equation.
Divide both sides by 2.5 to get x.
5.19/2.5 = 2.07
x = 2.07
I hope this helps!
