region.)

Yes.x+6 is a factor of f(x)=-x^2+6x

Answer:

no

Step-by-step explanation:

f(x) = -x^2 + 6x

The right side has a common factor. It is x.

Factor x out on the right side.

f(x) = x(-x + 6)

When the common factor x is factored out, the remaining factor is -x + 6.

-x + 6 is not equal to x + 6.

Answer: no

Diagram attached

Answer:

72 degrees

Explanation:

From the diagram, angle on a straight line add up to 180 degrees.

180 degrees - 144 degrees = 36 degrees.

Sum of the angles in a triangle= 180 degrees

Angles x and the other are congruent(the marks from the diagram indicate).

Therefore sum of the congruent angles= 180 degrees - 36 degrees = 144 degrees

Angle x= 144/2= 72 degrees

Answer:

x = 240

Step-by-step explanation:

Using the Altitude- on- Hypotenuse theorem

( leg of big Δ )² = ( part of hypotenuse below it ) × ( whole hypotenuse )

x² = 144 × 400 = 57600 ( take the square root of both sides )

x = [tex]\sqrt{57600}[/tex] = 240

Step-by-step explanation:

a). 0.03 (km)³ = 0.03(1000m)³

                      = 0.03 × 10⁹

                      = 3 × 10⁷ m³

b). 5.43 cg³ = 5.43(0.01g)³

                   = 5.43 × (10⁻⁶) g³

c). 6052 mL³ = 6052(10⁻³L)³

                      = 6052 × 10⁻⁹ L³

                      = 6.052 × 10⁻⁶ L³

d). 2100 m³ = 2100(10⁻³Km)³

                   = 2100 × 10⁻⁹ Km³

                   = 2.1 × 10⁻⁶ Km³

Answer:

0.2m x 0.12m

Step-by-step explanation:

A scale drawing is a reduced form in terms of dimensions of an original image / building / object

the scale drawing is usually reduced at a constant dimension

scale of the drawing = original dimensions / dimensions of the scale drawing

Scale of drawing = (10 / 50) x (6/50) = 0.2m x 0.12m

Answer:

2 and 2/6ths

SBSE:

1. multiply the denominators together (in this case, 24)

2. multiply each numerator by the denominators

3. reduce the 5 to four, making 4/24ths into 28/24ths

4. subtract the fractions and whole numbers.

Answer:

13x + 11y = 212

Step-by-step explanation:

total cost of purchasing an item = unit cost x total units purchased

total cost of purchasing pepperoni pizza = 13 × x = 13x

total cost of purchasing plain pizza = 11 × y = 11y

total cost of purchasing both items = total cost of purchasing pepperoni pizza + total cost of purchasing plain pizza

- 13x + 11y = 212

Answer:

[tex]\frac{1}{15}[/tex]

Step-by-step explanation:

There are 2 yellow marbles, 3 pink marbles, and 5 blue marbles in the bag, for a total of 10 marbles.

Let's start with the probability that the first marble drawn is pink. Since there are 3 pink marbles out of the 10 total marbles, the probability of this happening is [tex]3/10[/tex].

Since the first marble is not put back in the bag, there are now 9 marbles left, 2 of then being pink. The chances of drawing a pink marble now is [tex]2/9[/tex]. To find the chances of both of these events happening, multiply them together to get:

[tex]\frac{3}{10}\cdot \frac{2}{9}=\frac{6}{90}=\boxed{\frac{1}{15}}[/tex]

Step-by-step explanation:

Let x and y be two integers

x * y = 132

x + y = -23

x= -23 - y

y(-23 - y) = 132

-23y - y^2 = 132

y^2 +23y + 132 = 0

(y + 11) (y + 12) = 0

y = -11 or - 12

If y = -11 then x + (-11) = -23 -> x = -12

If y = -12 then x + (-12) = -23 -> x = -11

So the two integers are -11 and -12

The solution to the equation 30x² - 28x + 6 = 0 is x = 3/5 and x = 1/3 option (B) and (E) are correct.

Any equation of the form [tex]\rm ax^2+bx+c=0[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.

As we know, the formula for the roots of the quadratic equation is given by:

[tex]\rm x = \dfrac{-b \pm\sqrt{b^2-4ac}}{2a}[/tex]

We have a quadratic equation:

30x² - 28x + 6 = 0

a = 30, b = -28, and c = 6

Plug the values in the formula:

[tex]\rm x = \dfrac{-(-28) \pm\sqrt{(-28)^2-4(30)(6)}}{2a}[/tex]

After solving:

x = 3/5 or x = 1/3

Thus, the solution to the equation 30x² - 28x + 6 = 0 is x = 3/5 and x = 1/3 option (B) and (E) are correct.

Answer:

y = 3x - 11

Step-by-step explanation:

Parallel lines have the same slope so the relationship of x and y stays the same only the constant, b,  changes

y = 3x + b

plug in point (2, -5) to find "b"

-5 = 3(2) + b

-5 = 6 + b

subtract 6 from both sides

-11 = b

The equation is

y = 3x - 11

Answer:

(2 , -5) are the points

then y =3x-x,let 4 be x

substitute 2&-5 in the line

-5 =3(2)-x

-5=6-x

-x=6 +5

=11

:x =-11

y=3x - (-11)

y =3x+11
