Answer:

C) y=4x+2

Step-by-step explanation:

let's check all the options:

  • A) y=2(4)x=8x

if x = a

y(a)=8a

and now with x = a + 2

y(a+2)=8(a+2)=8a+16

the answer increased by 16. it is not the right option

  • B) y=2(8x)=16x

if x = a

y(a)=16a

and now with x = a + 2

y(a+2)=16(a+2)=16a+32

the answer increased by 32. it is not the right option

  • C) y=4x+2

if x = a

y=4a+2

and now with x = a + 2

y(a+2)=4(a+2)+2=4a+8+2=4a+10

this time, between 4a+2 and 4a+10 there is a difference of 8.

so for this function the statement is true.

Select the two values of x that are roots of this equation. 2x2 + 7x + 6 = 0
Anna007 [38]

Answer:

x = -3/2, -2

Step-by-step explanation:

2x^2 + 7x + 6 = 0

(2x + 3)(x + 2) = 0

(2x + 3)

2x = -3

x = -3/2

(x + 2)

x = -2

G = x-c/x solve for x
Elan Coil [88]

Answer:

x=\frac{c}{1-g}

Step-by-step explanation:

Step 1: Multiply both sides by x,

 gx=−c+x

Step 2: Add -x to both sides.

gx+−x=−c+x+−x

gx−x=−c

Step 3: Factor out variable x.

x(g−1)=−c

Step 4: Divide both sides by g-1.

\frac{x(g-1)}{g-1} =\frac{-c}{g-1\\}

x=\frac{c}{1-g}

Hope this helps!
