The two equations given in the question are

4x _ 3y = 3
And
5x _ 4y = 3
Multiplying the first equation by 4 and the second equation by 3, we get
16x - 12y = 12
15x - 12y = 9
Subtracting the second equation from the first equation, we get
x = 3

I hope the above procedure is clear enough for you to understand. I hope that this is the answer that you were looking for and the answer has actually come to your great help.

Answer:

49.5 mi

Step-by-step explanation:

Area of a triangle is   A = (height) X (base) / 2

So if you plug in the numbers you get:

806.9 = (32.6) X (base) / 2

1613.8 = (32.6) X (base)

1613.8 / 32.6 = base

base =  49.5 mi

The graph of a linear function passes through the point (-1, 2) and has a slope of 3. What is the equation of the function in sl
Harman [31]

Answer:

The equation of the function in slope-intercept form is y = 3 x + 5 .

Step-by-step explanation:

Given as :

A line passes through the point ( - 1 , 2 )

i.e ( x , y ) = ( - 1 , 2 )

The slope of the line is 3

The equation of line in slope intercept form

y - \textrm y_1 = m ( x - \textrm x_1 )

Where m is the slope of the line

So, y - 2 = 3 ( x - ( - 1 ) )

Or, y - 2 = 3 ( x + 1 )

Or, y - 2 = 3 x + 3

Or, y = 3 x + 3 + 2

∴   y = 3 x + 5

Hence The equation of the function in slope-intercept form is y = 3 x + 5 . Answer

ANSWER FOR BRAINLIEST<br> Identify the graph for the point C(−2, −1, 2) in three-dimensional space.
ioda

Answer:

the topmost one maybe?

Step-by-step explanation:

I'm guessing since X & Y are negative, (it's written X,Y,Z, right?)

The point would be reducing on the X&Y axes, an since Z is positive, it would increase on the Z axis

Firlakuza [10]

Answer:

x=1 or x=−2 or x=−3

Step-by-step explanation:

x3+4x2+x−6=0

Step 1: Factor left side of equation.

(x−1)(x+2)(x+3)=0

Step 2: Set factors equal to 0.

x−1=0 or x+2=0 or x+3=0

x=1 or x=−2 or x=−3
