Answer:

x=6

Step-by-step explanation:

4x-1=2x+11

4x-2x-1=11

2x-1=11

2x=11+1

2x=12

x=12/2

x=6

X = 6

You need to isolate the variable or get x on one side of the = sign and a number on the other side.

1. Do the inverse operation and add one to each side of the equation. -1+1= 0 and 11+1=12

2. Subtract 2x from both sides. 2x-2x=0 and 4x-2x=2x.

So we are left with 2x=12 or 2 times some number “x” is equal to twelve.

3. Next we divide both sides by 2
2/2=1 and 12/2=6

So x=6

PLEASE HELP!!

ElenaW [278]

Answer:

-1 and -3

(n+7)(n-8)

Step-by-step explanation:

1. Find the Zeros

$f(x)=x^{2} +4x+3$

$f(x)=\left(x+1\right)\left(x+3\right)$

$x+1=0\\x=-1\\x+3=0\\x=-3$

2. Factoring Trinomials

$f(x)=n^{2} -n-56$

$f(x)=\left(n+7\right)\left(n-8\right)$

$n+7=0\\n=-7\\n-8=0\\n=8$

Hich statement best describes a graph of paired points that form a proportional relationship?

Yanka [14]

Answer:

A. A straight line can be drawn through all the points and the line passes through the point (0,0) .

Step-by-step explanation:

See comment for options

Given

A graph with proportional relationship

Required

Which of options (a to d) describes the graph

A graph with a proportional relationship is represented as:

$y = kx$ and

$(x,y) = (0,0)$ is a paired point on the graph

This implies that options (b) and (c) are not true

Option (d) is also incorrect because if the graph does not pass through all points, then it is not proportional.

<em>Hence, (a) is correct</em>

Data:
r (radius) = 14 m
h (height) = 6 m
v (volume) = ?

Formula:
$V = \pi *r^2*h$

Solving:
$V = \pi *r^2*h$
$V = \pi *14^2*6$
$V = \pi *196*6$
$\boxed{\boxed{V = 1176 \pi\:m^3}}\end{array}}\qquad\quad\checkmark$
