Answer:

x = 7.5

Step-by-step explanation:

5/6 = 10/2x-3

Solve using cross products

5 ( 2x-3) = 6*10

Divide each side by 5

2x-3 = 6*10/5

2x-3 =12

Add 3 to each side

2x-3+3 = 12+3

2x =15

Divide each side by 2

2x/2 = 15/2

x = 7.5

Answer:

There is a local maximum at the point (-1,6), therefore, for x = -1

Step-by-step explanation:

Notice that the function adopts values smaller than 6 to the left of x = -1, and to the right of it:

(-3, -2), (-2, 0) to the left of x = -1 where the function's value is 6

and (0, 0), and (1, -2) to the right of x = -1

therefore, it looks like (-1, 6) is a maximum, that is for x = -1, where the function renders a value of 6.

Answer:

D is the correct answer

Answer: B

Step-by-step explanation:

If there is a change in something it normal means you subtract 1 number from another.

In this case the two values were 5 and -11.

At midday for answer b, it was 5  and at midnight it -11. It then wants to know the change in temperature which would result in an expression of 5-(-11).

Answer:

x = 0 or x = 4

Step-by-step explanation:

x² + y² = 25 and y = -2x + 5

Here,

x² + y² = 25 ...(1)

Now,

Put the value of y = -2x + 5 in equation (1)

we get,

x² + (-2x + 5)² = 25

x² + {(-2x)² + 2(-2x) (5) + (5)²} = 25

x² + {4x² - 20x + 25} = 25

x² + 4x² - 20x + 25 = 25

5x² - 20x = 25 - 25

5x² - 20x = 0

5x(x - 4) = 0

5x = 0 or x - 4 = 0

x = 0/5 or x = 4

x = 0 or x = 4

Answer:

x = 0, x = 4

In circle C, RT= 6, RS = 10, and QT= 3. What is the length of line segment PQ?

In circle C, RT= 6,

RS = 10, and

QT= 3.

What is the length of line segment PQ?

[tex](RT) (RS) = (QT) (PQ)[/tex]

so plug that in

[tex](6)(10)=(PQ)(3)[/tex]

[tex](6)(10)=(PQ)(3) \\\\60=(PQ)(3)\\\\PT=\frac{60}{3} \\\\PQ=20[/tex],

Answer:

X=20

70 x 2 for the other side = 140

every triangle has 180 degrees

180-140=40

There are 40 remaining degrees

there are two x's so we divide by 2

40 = X2

20 = X

Answer:

14%

Step-by-step explanation:

first, you would have to find how many skittles there are in total. You would add the red, blue, green, and purple skittles together and get 72. Next you would take the number of red skittles (10) and put it over the number of total skittles (72) and get the fraction 10/72. Lastly divide 10 by 72 and get the decimal .13888889 which would round up to .14 move the decimal over 2 places and get 14%

Answer:

the answer will be x=-9

Step-by-step explanation:

-5(x+6)=15

-5x-30=15

-5x=15+30

-5x=45

×=-9

Answer:

[tex]x=-9[/tex]

Step-by-step explanation:

[tex]-5(x+6)=15[/tex]

Use the distributive property.

[tex]-5x-30=15[/tex]

Add [tex]+30[/tex] on both sides of the equation.

[tex]-5x=15+30[/tex]

[tex]-5x=45[/tex]

Divide [tex]-5[/tex] on both sides of the equation.

[tex]x=45/-5[/tex]

[tex]x=-9[/tex]

Answer: always

Step-by-step explanation:

A right triangle is a kind of triangle with one right angle.

A theorem of right triangle says that :-

Hence, the statement "The altitude to the hypotenuse of a right triangle is the geometric mean between the segments on the hypotenuse."  is always true.

Thus , the correct answer is "always".

Your answer should be always :)

Answer:

It seems to be D)9 from intervals 1 to 3...

Step-by-step explanation:

Can't really explain that well, but the rate of change in an exponential function should always be decreasing or increasing. Instead of it being constant like a linear equation.

I.E. Not additive, instead to find it we need to divide.

[tex]\frac{27}{3} =9[/tex]

So, it should be 9. However, It does not seem to be maintained for the values after 3. Oh well!

Hope this helps!

The average rate of change of the function is 12.

The rate of change function represents the rate at which one quantity changes in relation to another. Simply put, the rate of change is the difference between the amount of change in one item and the comparable amount of change in another.

Rate of change = [ y₂ - y₁ ] / [ x₂ - x₁ ]

The rate of change for x₁ = 1 to x₂  = 3 at x₁ = 1 ,y₁ = 3 and at x₂= 3, y₂ = 27.

Rate of change =  [ y₂ - y₁ ] / [ x₂ - x₁ ]

                          = [ 27 - 3 ] / [ 3 - 1 ]

                          = [ 24 / 2 ]

                          = [ 12 ]

Hence, the correct option is A.

Answer: 12 inches

Step-by-step explanation:

Vol = 1/3 x b x h

240 = 1/3 x b x 15
