Determine whether the following statement is true or false. The y-coordinate of the vertex of f(x) = - X + 4x + 3 is f(2). Select the correct choice below and fill in the answer box to complete your choice. A. The statement is true because the x-intercept of the parabola is B. The statement is false because the y-coordinate of the vertex is f(()). C. The statement is true because the x-coordinate of the vertex is 4 D. The statement is false because the y-coordinate of the vertex is​

The coordinates of B is (-6, -7)

The given parameters are

A = (4, -3)

M = (-1, -5)

The midpoint of a line is calculated as

M = 1/2(x1 + x2, y1 + y2)

So, we have

(-1, -5) = 1/2 * (4 + x, -3 + y)

This gives

(-2, -10) = (4 + x, -3 + y)

Solve for x and y

4 + x = -2

-3 + y =-10

Evaluate

x = -6 and y = -7

Hence, the coordinates of B is (-6, -7)

Answer:

y≤9.45

Step-by-step explanation:

Step 1: Simplify both sides of the inequality.

0.37037y≤3.5

Step 2: Divide both sides by 0.37037.

0.37037y/ 0.37037 ≤  3.5 /0.37037

So when we do the division we end up with the answer being -

Y≤  9.45

Step-by-step explanation:

Answer:

x = 15

y = 19

Step-by-step explanation:

(5x-5) = (4x+10) reason[ being corresponding angle]

or, 5x-4x = 10+5

or, x = 15.

Similarly,

(5x-5)+(6y-4) = 180 reason[being supplementary angle]

putting the value of x in the equation, so

or, (5*15 -5)+(6y-4) = 180

or, 75-5+6y-4 = 180

or, 66+6y = 180

or, y = 30-11

or, y = 19.

Another way to state it is to say that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. If you put the two shortest sides end to end, they have to be longer than the longest side to be able to angle up to form a triangle.

Answer:

3. 3, 5, 7

4. 1.1, 2.2, 3.2

5. 13, 5, 12

7. 5, 4, 3

8. 4, 4, 3

Step-by-step explanation:

In a triangle, the sum of the lengths of any two sides must be greater than the length of the third side.

1. 19, 16, 3

16 + 3 = 19

No triangle

2. 1, 2, 3

1 + 2 = 3

No triangle.

3. 3, 5, 7

3 + 5 = 8 > 7

3 + 7 = 10 > 5

7 + 5 = 12 > 3

Triangle

4. 1.1, 2.2, 3.2

1.1 + 2.2 = 3.3 > 3.2

2.2 + 3.2 = 5.4 > 1.1

1.1 + 3.2 = 4.3 > 2.2

5. 13, 5, 12

13 + 5 = 18 >12

5 + 12 = 17 > 13

13 + 12 = 25 > 5

Answer:

Since the base of a cone is a circle, we substitute 2πr for p and πr2 for B where r is the radius of the base of the cylinder. So, the formula for the lateral surface area of a right cone is L. S. A=πrl , where l is the slant height of the cone .

Answer:

1.917

Step-by-step explanation:

The difference between 4.091 and 2.174 will be;

⇒ 1.917

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that;

The numbers are,

⇒ 4.091 and 2.174

Now,

Since, The numbers are,

⇒ 4.091 and 2.174

Hence, The difference the number 4.091 and 2.174 is,

⇒ 4.091 - 2.174

⇒ 1.917

Thus, The difference between 4.091 and 2.174 = 1.917

Answer:b

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

Because subtraction and addition are alike just how multiplication and division are.

The inverse of f(x) is (x+6)/5, the correct option is A

Suppose that the given function is

[tex]f:X\rightarrow Y[/tex]

Then, if function 'f' is one-to-one and onto function (a needed condition for inverses to exist), then, the inverse of the considered function is

[tex]f^{-1}: Y \rightarrow X[/tex]

such that:

[tex]\forall \: x \in X : f(x) \in Y, \exists \: y \in Y : f^{-1}(y) \in X[/tex]

It simply means, inverse of 'f' is undo operator, that takes back the effect of 'f'

Given;

f(x) = 5x - 6

f^-1 (x ) = x+6/5

Let, y = f(x) and rearrange making x the subject;

y = 5x - 6 ( add 6 to both sides )

y + 6 = 5x ( divide both sides by 5 )

x = (y+6)/5

Change y back into terms of x

x  = (x+6)/5

Therefore, the answer in inverse will be (x+6)/5

Answer:   x = 6

Step-by-step explanation:

Angles 1 and 8 are alternate exterior angles, so they are equal.

so you can create an equation to solve for x

12x−20 = 2x+40  Subtract 2x from both sides. Add 20 to both sides

10x = 60

x = 6

if you need the  m∠1, Substitute 6 for x.  (2x+40)°  2(6) +40= 12+40 m∠1= 52°

m∠8=(12x−20)°   12(6) - 20 = 72-20  m∠8 = 52°
