Simplify the expression 4a ­− 5b −­ 6 + 2b −­ 3a.

Answer:

X=-3/7(Fraction form)

or

x=-0.428571 (Decimal form)

Answer: -1/343

Step-by-step explanation:

-7(-7)^-4

First, re-write as positive exponents:

-7(-1/7^4)

Next, simplify:

-1/7^3 (you can simplify using exponent rules)

Simplify 7^3 :

7(7)(7)

49(7)

343.

Insert to original expression:

-1/343.

Step-by-step explanation:

Hey there!

The equation in y=mx+b is [tex]y=-\frac{1}{2}x+1[/tex]

To write in standard form, it would look like: [tex]Ax+By=C[/tex]

As you can see, the x and y should be on the same side. You will need to move [tex]-\frac{1}{2}x[/tex] to the other side. When moving a number/variable to the other side, the sign changes, therefore, the negative sign will be removed. It is also the same as adding the opposite of it to both sides.

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

In standard form, there are no fractions, only whole numbers. The fraction can be removed by multiplying it by its opposite. The opposite of [tex]\frac{1}{2}[/tex] is [tex]\frac{2}{1} \rightarrow 2[/tex].

The entire equation has to be multiplied by 2:

[tex](y+\frac{1}{2}x=1) \times 2 \rightarrow 2y+x=2[/tex]

[tex]x+2y=2[/tex]

Hope this helps!

add them to gether u get .7

subtract it by 1.0 because its a whole and you get .3

Answer:

2(n-4)

Step-by-step explanation:

The common factor of this expression is 2 because it can divide into both 2n and 4; therefore, if you divide the entire expression by 2, you'll result in an answer of 2(n-4).

The common factor out of each expression 2(n-4)

Since factorization is the technique of breaking a number into smaller numbers that multiplied together will give that original form.

We are given the expression;

2n - 4

The common factor of this expression is 2

Since it can divide into both 2n and 4;

Therefore, if we divide the entire expression by 2, results in an answer of 2(n-4).

Answer: 473.39

Step-by-step explanation:

444.50 + 0.065*444.50 = (1 + 0.065)*444.50 = 1.065*444.50 = $473.39

Based on the information given the  television cost with tax included is $473.39.

Using this formula

Cost=Principal+(Principal× Sales tax)

Where:

Principal=$444.50

Sales tax=6.5%

Let plug in the formula

Cost=$444.50+($444.50×6.5%)

Cost=$444.50+$28.89

Cost=$473.39

Inconclusion the  television cost with tax included is $473.39.

Answer:

[tex]Acceleration = 33.96ms^{-2}[/tex]

Step-by-step explanation:

Given

[tex]Mass = 53kg[/tex]

[tex]Force = 1800N[/tex]

Required

Determine the acceleration

The relationship between force, mass and acceleration is:

[tex]Force = Mass * Acceleration[/tex]

Substitute values for Force and Mass

[tex]1800 = 53 * Acceleration[/tex]

Solve for Acceleration

[tex]Acceleration = 1800/53[/tex]

[tex]Acceleration = 33.9622641509[/tex]

[tex]Acceleration = 33.96ms^{-2}[/tex]---- Approximated

Answer:

The approximate side length is between 10 ft and 11 ft

Step-by-step explanation:

Here, we are interested in calculating the approximate length of the square shaped pool.

Mathematically, the area of a square is s^2 where s represents the length of its side

in this case; s^2 = 120

s = √120

s = 10.95 approximately

So the length of the side of the square is between 10 and 11 ft

Answer:

a = 3

Step-by-step explanation:

Factorise both expressions\x² - x - 6 = (x - 3)(x + 2)

x² + 3x - 18 = (x - 3)(x + 6)

Thus both expressions have a common factor of (x - 3) , thus

a = 3

Step-by-step explanation:

The circumference of a circle's formula is pi*d (d being diameter).

If it only shows you the radius, then the formula would be 2*pi*r (r being radius), this is the same as pi*d.

2*r = d
