A) translation of 4 units down followed by a dilation with respect to the origin by a scale factor of 2
Answer:
x = 43
Step-by-step explanation:
2x + 16 = 3(x - 9)
2x + 16 = 3x - 27
2x - 16 = 3x -27 (-16)
2x = 3x -43
2x (-3x) = -43
-1x or -x
-x = -43
-43/ -x = 43
y^2-1= 35
Move -1 to the other side. Sign changes from -1 to +1.
y^2-1+1= 35+1
y^2= 36
Square root 36:
6 and -6
Answer: 6 and -6
Answer: 15/8
Step-by-step explanation:
We are given that Kristine spends $20 and saves the rest each time she get paid.
We can use slope-intercept form y=mx+b to represent the equation.
Where x represents the amount Kristine earns and y represents the amount she saves.
Kristine spends $20. Therefore b= -20.
Plugging mx as just x and b=-20.
<h3>y = x-20.</h3><h3>If we plug y=0, we get </h3><h3>0 = x-20</h3><h3>x=20.</h3><h3>We can see in 4th option we have x-intercept =20.</h3><h3>Therefore, correct option is 4th option. </h3><h3 />
