Answer:
b) y = f(x) = -3x+4
Step-by-step explanation:
<u><em>Explanation</em></u>
Given that the equation 9x+3y =12
Let 'x' be an independent variable and 'y' be the dependent variable then the function is of the form
y = f(x)
3 y = 12 - 9x
y = -3x+4
The function represented by y = -3x+4
Answer:
y = (9/4)x + 2, given that I've assume the correct meaning of "-5x4."
Step-by-step explanation:
A parallel line has the same slope as the reference line,
The reference line is 9x-4y = -5x4, as written. I'm not sure the 4 belongs, but I'll assume it is written correctly. I'm not sure if the term -5x4 is meant to mean -5x^4, -20x or -20. I'll assume -20:
9x-4y = -20
Put the equation into standard slope-intercept form: Y = mx + b, where m is the slope and b is the y-intercept (the value of y when x = 0).
-4y = -9x - 20
y = (9/4)x + 5
This line has a slope of (9/4). The parallel line will have the same slope.
y = (9/4)x + b
We can find a value of b that would shift this line to include (4,7) by using this point in the equation:
y = (9/4)x + b
7 = (9/4)(4) + b
7 = 9 + b
b = 2
The equation of a line parallel to the reference line is y = (9/4)x + 2

Answer:
Hi myself Shrushtee.
Step-by-step explanation:
The equation of the translated circle is:
(x+7)2+(y+2)2=25 .
Explanation:
The standard form of a circle is
(x−h)2+(y−k)2=r2 ,
where r is the radius of the circle and
(h,k)
is the center of the circle.
In x2+y2
=25, the center is at
(0,0)
. When the circle is translated left 7 units, it means that the new center has
h=−7
. Translating the circle down 2 units means that the new center has
k=−2
So, the translated circle has the equation
(x+7)2+(y+2)2=25 .
