x > -18

Step-by-step explanation:

10 ( x - 9 ) > -270

Treat the inequality like an equation,

Distribute first:

10 ( x - 9 ) > - 270

10x - 90 > -270

Inverse operations:

10x - 90 > -270

      +90    +90

10x > -180

/10     /10

x > -18

The derivation of the quadratic function is true

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the quadratic equation be represented as A

Now , the value of A is

ax² + bx + c = 0

Step 1 :

ax² + bx + c = 0

Step 2 : Subtracting c on both sides , we get

ax² + bx = -c

Step 3 : Divide by x on both sides , we get

ax + b = -c/x

Hence , the steps are true in solving the quadratic equation

Answer:

The slope is most easily defined as rise over run.

First, find a point you like because it is directly on the line and is where for example starting from the origin which you know should be always (0, 0).

Then find another point that is on the line and is perfectly aligned where on the graph is like (1, 2).

Then, as I said earlier, rise over run. So you climb up from for example the origin which is in the graph and climb up to the (1, 2) point. It should go up two units because it is increasing in intervals of 2 but has the notches in the half mark of 1.

So the rise is 2 because it climbed from 0 to 2.

The run is running from the 0 in the origin on the x-axis and running to the 1 because it is (1, 2) where it is in the form (x,y).

Since it is rise over run, the rise is 2 and the run is 1 so 2 over 1 is 2.

Hence the slope is 2.

Answer: its either a or b

Error is the difference between the actual length of an object and its measured length.

The closest to the percent error for Diego's measurement is 4.3%

Error = Actual length - Measured length

= 23cm - 22cm

= 1 cm

Formula = Error/ Actual length × 100

= 1 /23 × 10

= 4.35%

Therefore, the closest to the percent error for Diego's measurement is 4.3%

Answer:

Use synthetic division to solve

Step-by-step explanation:

When dividing a polynomial by a zero, you first want to find the zero to divide by. Solving the zero (x+2) will give us the value of x to divide by. Subtracting 2 from each side gives us x=-2. Then, we write out the full polynomial. Since the only degrees that have numerical values are x^5 and 32, we substitute zero for the values in between (0x^4, 0x^3, 0x^2, and 0x). Then we follow the steps of synthetic division (as seen in the photo) to find our new values for our new equation.

Step-by-step explanation:

Make a point P that will be the vertex of the new angle.

From P, draw a ray PQ. ...

Place the compasses on point A, set to any convenient width.

Draw an arc across both sides of the angle, creating the points J and K as shown.

Hope this helps :)

Brandon

Step-by-step explanation:

2x + 3y = 8

-2x         -2x

3y = -2x + 8

y = (-2/3)x + 8/3

m = (-2/3)

even tho brandon did not divide 8 by 3, you were just supposed to find the slope of the line parallel to that line so for the most part, he is correct for the way he got his answer

Answer:

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

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 )

Given

2x + 3y = 8 ( subtract 2x from both sides )

3y = - 2x + 8 ( divide all terms by 3 )

y = - [tex]\frac{2}{3}[/tex] x + [tex]\frac{8}{3}[/tex] ← in slope- intercept form

with slope m = - [tex]\frac{2}{3}[/tex]

Parallel lines have equal slopes , thus

slope of parallel line = - [tex]\frac{2}{3}[/tex]

Answer:

Step-by-step explanation:

1) If I'm reading it correctly, the two angles are vertically opposite. <4 = 72

2) <3 + <5 are supplementary (the add to 180) <5 = 180 - 134 = 46

3) <2 = 99 then <3 is 99 and < 6 = 99 (alternate interior angles)

<7 = <6

<7 = 99

Same side interior angles are supplementary.

The width of the playground is 4/3 miles.

The formula for area is equal to the product of the length and breadth of the rectangle. Whereas when we speak about the perimeter of a rectangle, it is equal to the sum of all its four sides.

Given here, the length = 2/4 miles and Area = 8/12 miles

Thus width = 8/12 / 2/4

                   = 4/3 miles

Hence, the width of the playground is  4/3 miles.

Answer:

The missing x = 0.675 m

Step-by-step explanation:

In similar triangles, the corresponding sides are proportion (means their ratios are equal)

In the given figure

∵ The two triangles are similar

∴ Their corresponding sides are proportion

∵ The sides of lengths 1.8 m and x are corresponding sides

∵ The sides of lengths 8.0 m and 3.0 are corresponding sides

∴ [tex]\frac{1.8}{x}[/tex] = [tex]\frac{8.0}{3.0}[/tex]

→ By using cross multiplication

∴ x × 8.0 = 1.8 × 3.0

∴ 8x = 5.4

→ Divide both sides by 8

∵ [tex]\frac{8x}{8}[/tex] = [tex]\frac{5.4}{8}[/tex]

∴ x = 0.675

→ No rounding because there is no digit after the thousandth digit

∴ x = 0.675 m

First, you should convert the fractions into decimals to make it easier, which would make it, 1.5, .25, 1.

Second, multiply 1.5 by 2 because there are 1.5 pounds which are payed for $2.00. Do the others fractions corresponding with the number of pounds and the cost this same way. 1.5 multiplied by 2 is 3. .25 multiplied by 1.60 is 0.4, 1 multiplied by 1.65 is 1.65.
