The equation of the linear function is given in the form of a directional
equation consists of solid :
1.współczynniki a and b .
2. The variables x and y

y= 3x - 12
y = ax + b
a = 3 (the slope of the tangent to the x-axis)
b = - 12 (intersection of the axis y)
we look for the point ( 0 , -12 ) because b = -12

A. (4, 0) ,(0, -12)
B.(12 ,0), (0,4)
C.(3, 0), (0, 4)
D.(4, 0), (0, 3)
E.(-4, 0), (0, -12)

fit and answers a,e

we set the coordinate system and you activate the point ( 0 , -12 )
Now draw a straight line parallel to the x axis przchodzącą through the point (0 , -12 )
We notice that a> 0 the function is increasing

We draw a line parallel to the triangle . Invent lengths of the sides 3 : 1. Examples are a = b = 1cm 3cm and 6cm a = b = 2 cm .

the hypotenuse of the triangle is our simple
Intersection of the axis x = ( 4,0 )

If the amount of vat paid by a customer while buyong a bag at 13℅ vat rate rs 143 ,find the cost of bag without vat

Darya [45]

Step-by-step explanation:

vat %=13%

vat=143

vat = vat% of sp (i.e sp without vat)

143 = 13/ 100 of sp

143*100=13sp

14300/13 = sp

sp=4766.67

therefore the cost of bag without vat is rs.4766.67

Find the solution to the system. Write your solution as an ordered pair (x,y) with no spaces, no solution, or infinitely many. x

eimsori [14]

Answer:

(7, - 1)

Step-by-step explanation:

$x = y + 8.....(1) \\ \\ x = 5y + 12....(2) \\ \\ from \: equations \: (1) \: and \: (2) \\ \\ 5y + 12 = y + 8 \\ \\ 5y - y = 8 - 12 \\ \\ 4y = - 4 \\ \\ y = \frac{ - 4}{4} \\ \\ y = - 1 \\ \\ plug \: y = - 1 \: in \: equation \: (1) \\ \\ x = - 1 + 8 \\ \\ x = 7 \\ \\ (x, \: y) = (7, \: - 1)$
