Answer:

Step-by-step explanation:

✯Hello✯

↪ So first we need to eliminate the smaller value for x by adding 2 to both sides

↪ We then have 4x-1=3

↪ Add 1 to both sides so 4x=4

↪ Divide both sides by 4 and x=1

HOPE THIS HELPS

The volume of the cone is 130 units^3. Solve for x.<br> Height: 13<br> Radius: x

Gwar [14]

V=(1/3)hpir^2
v=130
h=13
r=x

130=(1/3)(13)pix^2
times both sides by 3
390=13pix^2
divide both sides by 13
30=pix^2
divide both sides by pi
30/pi=x^2
sqrt both sides
x≈3.09
radius is abou 3 units

Which equation describes a line parallel<br> to y= 4x+ 5 through point (-2, 1)?

Tema [17]

Hi there!

For a line to be PARALLEL, it must contain the same slope.

The given line has a slope of 4, so we can use the point-slope formula to solve:

$\large\boxed{y - y_1 = m(x - x_1)}$

y1 = y-coordinate of given point

x1 = x-coordinate of given point

m = slope

Plug in the values:

$y - 1 = 4(x - (-2))\\\\y - 1 = 4(x + 2)$

Simplify:

$y - 1 = 4x + 8\\\\\boxed{y = 4x + 9}$
