Simplify the expression 9/(-3)+4/(-8)

Answer:

soln,

6x=12

so,x=2.........

Answer:

They are equal.

Step-by-step explanation:

Step 1: Evaluate 16/28

16/28 = 0.571429...

Step 2: Evaluate 28/49

28/49 = 0.571429...

Step 3: Compare

0.571429... ? 0.571429...

0.571429... = 0.571429...

So 16/28 = 28/49

First, turn the fraction into a decimal.

9.75

Second, multiply by 100%.

9.75 * 100% = 975%

Best of Luck!

Answer:

There are a total of 720 chairs in the theater

Step-by-step explanation:

First row = 20 chairs

Second row = 24 chairs

Third row = 28 chairs

The given is an arithmetic progression (A.P)

First term

a = 20

Common difference

d = 4

Number of terms

n=15

Sum of the chairs in the theater with a total of 15 rows

Sum of an A.P = n/2 { 2a + (n-1) d}

= 15/2{ 2*20 + (15-1) 4}

= 7.5 { 40 + (14) 4 }

= 7.5 { 40 + 56}

= 7.5(96)

=720 chairs

Answer:

[tex]\huge\boxed{(3, 8)}[/tex]

Step-by-step explanation:

When we rotate a point 90° counterclockwise around the origin, it's the same as rotating it 270° clockwise around the origin.

When we rotate something 270° clockwise around the origin, the original coordinates (x, y) becomes (-y, x).

y is -3, and -(-3) is just 3, since two negatives make a positive.

x just remains x, but it's in a different position.

This makes the new coordinate [tex](3, 8)[/tex].

Answer:

6x−5=(2)(3)x+4

Step 1: Simplify both sides of the equation.

6x−5=(2)(3)x+4

6x+−5=6x+4

6x−5=6x+4

Step 2: Subtract 6x from both sides.

Answer:

x = 4 + √3 and  x = 4 − √3

Step-by-step explanation:

(a−b)^2=a^2−2ab+b2

a^2−b^2=(a−b)(a+b)

−2x^2+16x−26

=−2(1x^2−8x+13)

=−2(x^2−8x+13+3−3)

=−2(x^2−8x+16−3)

=−2(x^2−2(4)x+4^2−3)

=−2((x−4)^2−3)

=−2((x−4)^2−(√3)^2)

=−2((x−4)−√3)((x−4)+√3)

=−2((x−(4+√3)((x−(4−√3))

The zeros of the given algebraic expression are:

−2x^2+16x−26=0

−2((x−(4+√3)((x−(4−√3))=0

x = 4 + √3 and  x = 4 − √3

I strongly suggest using the quadratic formula as this problem is much easier to solve using it.

Step-by-step explanation:

Step 1: Write out expression

5x²y - 3xy - 8 + 7xy + 4

Step 2: Combine like terms (xy)

5x²y + 4xy - 8 + 4

Answer:

x = 8                          x = 2

Step-by-step explanation:

1+3|x-5|=10

Subtract 1 from each side

1-1+3|x-5|=10-1

3|x-5|=9

Divide by 3

3/3|x-5|=9/3

|x-5|=3

There is a positive and negative solutions

x-5 =3            x-5 = -3

Add 5 to each side

x-5+5 = 3+5           x-5+5 = -3+5

x = 8                          x = 2

Answer:

[tex]x=2,8[/tex]

Step-by-step explanation:

So we have the equation:

[tex]1+3|x-5|=10[/tex]

First, subtract 1 from both sides:

[tex]3|x-5|=9[/tex]

Now, divide 3 from both sides:

[tex]|x-5|=3[/tex]

Definition of absolute value:

[tex]x-5=3\text{ or }x-5=-3[/tex]

For the left, add 5 to both sides.

For the right, add 5 to both sides:

[tex]x=3+5\text{ or } x=-3+5\\x=8\text{ or }x=2[/tex]

Thus, the answers are:

[tex]x=2,8[/tex]

Answer:

The expression is false

Step-by-step explanation:

Given

[tex]f - (g - h) = (f - g) - h[/tex]

Required

True or False

To determine if the expression is true or false, we need to simplify both sides of the equation

[tex]f - (g - h) = (f - g) - h[/tex]

Start by opening the bracket on the right hand side

[tex]f - (g - h) = f - g - h[/tex]

Then open the bracket on the left

[tex]f - g + h = f - g - h[/tex]

Subtract f - g from both sides

[tex]f - g - (f - g) + h = f - g - (f - g) + h[/tex]

[tex]f - g - f + g + h = f - g - f + g - h[/tex]

[tex]f - f - g + g + h = f - f - g + g - h[/tex]

[tex]h \neq -h[/tex]

Hence;

The statement is false

To further check;

Assume f = 5; g = 4 and h = 3

[tex]f - (g - h) = (f - g) - h[/tex] becomes

[tex]5 - (4 - 3) = (5 - 4) - 3[/tex]

[tex]5 - 4 + 3 = 5 - 4 - 3[/tex]

Answer:

0.6 deg/s²

Step-by-step explanation:

Acceleration is the time rate of change of velocity, it is the ratio of velocity to time. The formula for acceleration is given by:

Acceleration = Change in velocity / time taken = (Final velocity - Initial velocity) / time

Given that the acceleration is 2160 deg/min², we have to convert it to deg/s²

1 min = 60 seconds

1 min² = 60² s² = 3600 s²

[tex]2160\ deg/min^2=\frac{2160\ deg}{1\ min^2*3600\ \frac{s^2}{min^2} }=0.6\ deg/s^2\\ \\2160\ deg/min^2=0.6\ deg/s^2[/tex]

Answer:

$278.40

Step-by-step explanation:

Note: "...an additional 10% off any shoe item, once the first discount has been applied." (emphasis added).

Note that the customer is buying 3 pairs of shoes for $120 each: 120 x 3 = $360

The first discount is the 20% discount  (on every single item), the second discount is the 10% discount coupon of of any item (which signifies one item only).

Solve for the first discount:

$360 x 0.20 = $72

$360 - 72 = $288.

Next, divide $288 by 3 (to get the individual prices of the shoes:

$288/3 = $96.

The customer then uses a birthday coupon for one of the shoes, which gives an additional 10% off.

$96 x 0.10 = 9.6

$96 - 9.6 = $86.4

Remember, the other two shoes still cost $96 each. Add the price together:

$96 + $96 + $86.4 = $278.40

$278.40 will be the total.

Step-by-step explanation:

Given g(x)=3x2+3 find x if g(x)=78 = 5

Hope this helped you :)

Answer:

x = ± 5

Step-by-step explanation:

Given

g(x) = 3x² + 3 and g(x) = 78 , then equate the right sides, that is

3x² + 3 = 78 ( subtract 3 from both sides )

3x² = 75 ( divide both sides by 3 )

x² = 25 ( take the square root of both sides )

x = ± [tex]\sqrt{25}[/tex] = ± 5

That is x = - 5 or x = 5

Answer:

Step-by-step explanation:

Answer:

Domain: [tex](-\infty,\infty)[/tex]

Range: [tex](1,\infty)[/tex]

Step-by-step explanation:

The domain of a function is the span of x-values it covers.

The range of a function is the span of y-values it covers.

From the graph, we can see that the domain stretches infinitely in both directions. Therefore, the domain is all real numbers.

In interval notation, this is:

[tex](-\infty,\infty)[/tex]

For the range, note that horizontal line at y=1.

The dotted line tells us that there is a horizontal asymptote there. In other words, y would never reach exactly 1.

Thus, our range would be all values greater than 1 (to positive infinity).

In interval notation, this is:

[tex](1,\infty)[/tex]

And we're done :)
