Which of these are the intercepts of the graph of y=3x-12
lutik1710 [3]
<span>The equation of the linear function is given in the form of a directional
</span><span>equation consists of solid :
1.współczynniki a and b .
2. The variables x and y

</span>y=  3x - 12
y = ax + b 
a = 3      (<span>the slope of the tangent to the x-axis)
</span>b = - 12  (<span>intersection of the axis y)
</span>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)

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

</span><span>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 .

</span><span>the hypotenuse of the triangle is our simple

20 to 25 percent change
inna [77]
A change from 20 to 25 represents a positive change (increase) of 25% Percent change = [(20 - 25) / 20] x 100 = 25 % (increase)Where: 20 is the old value and 25 is the new value. In this case we have a positive change (increase) of 25 percent because the new value is greater than the old value.

Hope this helps :)
