Answer:

x= -1.

Step-by-step explanation:

4-2(x+7) = 3(x+5)

4 - 2x-14 = 3x +15

10-2x=3x+15

10=5x+15

-5 = 5x

-1 = x

Hope this helps. Let me know if you need any help.

Which transformations take f(x)=3x+1 to g(x)=−3x-5 ?
lbvjy [14]
<span>reflection over the x-axis and a translation 4 units down Refelcting f(x) over the x axis gives -f(x)=-3x-1 Subtracting a constant from -f(x) moves the graph of -f(x) that many units down. -f(x)-4=-3x-5=g(x) This shows that g(x) is obtained by reflecting f(x) over the x-axis and then translating 4 units down.</span>

Answer:

volume = Pi(2x^2+3x-5) x (2x+5)^2    or     P1(8x^4+52x^3+100x^2-125)

Step-by-step explanation:

radius = (4x+10)/2 = 2x+5

volume = Pi(2x^2+3x-5) x (2x+5)^2

volume = Pi(2x^2+3x-5) x (4x^2+20x+25)

volume = P1(8x^4+52x^3+100x^2-125)

Answer:

I think u have to find the distance.

Each point is given a distinct letter and like wise you have to count the distance between the two points given.

Step-by-step explanation:

Like, 1)distance between A and R when A = -11 and R = -9

their distance is 2 units.

Likewise, 2) RY = 6 units

3) EU = 7 units

4) WD = 5 units

5) EL = 12 units
