Half of a number x is equal to 9 less than 2 times that same number. What is the
number

Answers

Answer 1

Answer:

[tex]x = 6[/tex]

Step-by-step explanation:

Analyzing the statement one after the other:

Half a number x: [tex]\frac{1}{2}x[/tex]

Equals to: [tex]=[/tex]

9 less than twice that same number: [tex]2x - 9[/tex]

Bring them together, we have:

[tex]\frac{1}{2}x = 2x-9[/tex]

Collect Like Terms

[tex]\frac{1}{2}x - 2x= -9[/tex]

[tex]\frac{x}{2} - 2x= -9[/tex]

[tex]\frac{x - 4x}{2} = -9[/tex]

[tex]\frac{ - 3x}{2} = -9[/tex]

Multiply through by 2

[tex]2 * \frac{ - 3x}{2} = -9 * 2[/tex]

[tex]- 3x = -18[/tex]

Divide through by -3

[tex]x = 6[/tex]

Answer:

y = - 2 + [tex]\frac{1}{3}[/tex] x

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, - 2) and (x₂, y₂ ) = (6, 0) ← 2 points on the line

m = [tex]\frac{0+2}{6-0}[/tex] = [tex]\frac{2}{6}[/tex] = [tex]\frac{1}{3}[/tex]

The line crosses the y- axis at (0, - 2 ) ⇒ c = - 2

y = [tex]\frac{1}{3}[/tex] x - 2 , or

y = - 2 + [tex]\frac{1}{3}[/tex] x

Answer:

Proof

Step-by-step explanation:

"The y-intercept is - 2" and now I think the best way to prove the gradient is to prove it mathematically taking coordinates of the line and using:

[tex]m = \frac{y - y}{x - x} [/tex]

So I'll take the coordinates (6,0) and (0,-2) and substitute them in the formula for the gradient.

[tex]m = \frac{ - 2 - 0}{0 - 6} = \frac{ - 2}{ - 6} = \frac{1}{3} [/tex]

D. $13.50
PLS HELP!!!!!!!!!!!!!!!!!!!! (⊙﹏⊙) ( ̄_ ̄|||)

Answers

9514 1404 393

Answer:

  A.  $1.50

Step-by-step explanation:

You can probably read the cost from the graph. Find the x-axis position corresponding to 1 pen and locate the point on the graph above that position. Then read the y-coordinate (cost) from the vertical axis. It will be sufficiently close to $1.50 that you can easily determine that to be the correct answer choice.

__

Cost per pen is found by dividing cost by pens.

  $4.50/(3 pens) = $1.50 /pen*

Anthony is going to invest in an account paying an interest rate of 2.7% compounded quarterly. How much would Anthony need to invest, to the nearest hundred dollars, for the value of the account to reach $130 in 10 years?

Answers

Answer:

$99

Step-by-step explanation:

Given that :

Rate (r) = 2.7% = 0.027 Compounded quarterly

Final amount (A) = $130

Period (t) = 10 years

Principal = invested amount (p) =?

n = number of compounding tines per period = 12/3 = 4

Using the formula :

A = p(1 + r/n)^nt

130 = p(1 + 0.027/4)^(4*10)

130 = p(1 + 0.00675)^40

130 = p(1.00675)^40

130 = p(1.3087766)

P = 130 / 1.3087766

P = 99.329402

P = $99

Which equation represents line E, shown in the accompanying diagram?
A.)y=2x+3
B.)y=1/2x+3
C.)y=3x+1/2
D.)y=3x+2
Please help!!!!

Answers

Answer:

First, find the slope:

The slope is 1/2.

Now we have this much of the equation:

y = 1/2x + b

Plug in the point (0,3) to find the value of b

3 = (1/2)(0) + b

b = 3

Your final equation is y = 1/2x + 3.

Step-by-step explanation:

The equation of the line is y = x/2 + 3 which is passing through the points (-4, 1) and (0, 3) option (B) is correct.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

The straight line is shown in the coordinate plane.

The equation of the line passing through the points:

(-4, 1) and (0, 3)

From the two-point we can find the equation of the line:

y - 3 = (3-1)/(0+4)[x]

y = 2/4[x] + 3

y = x/2 + 3

Thus, the equation of the line is y = x/2 + 3 which is passing through the points (-4, 1) and (0, 3) option (B) is correct.
