=x+−41611y+−3+−2+−10

Combine Like Terms:

=x+−41611y+−3+−2+−10

=(x)+(−41611y)+(−3+−2+−10)

=x+−41611y+−15

Answer:

f(x) = 2(x - 2)² - 1

Step-by-step explanation:

Given the vertex, (2, -1) and the point, (0, 7), we can plug these values into the vertex form of the quadratic function:

f(x) = a(x - h)² + h

where:

vertex = (h, k)

a = determines whether the graph opens up or down, and the wideness or narrowness of the parabola.

h = determines how far left or right the parent function is translated.

k = determines how far up or down the parent function is translated.

We could substitute the given values into the vertex form, and solve for the value of "a":

f(x) = a(x - h)² + h

7 = a(0 - 2)² - 1

7 = a(-2)² - 1

7 = a(4) - 1

Add 1 to both sides:

7 + 1 = a(4) - 1 + 1

8 = 4a

Divide both sides by 4 to solve for a:

8/4 = 4a/4

2 = a

Since a = 2, and the vertex = (2, -1) then we could plug this value into the given function:

f(x) = 2(x - 2)² -1

Answer:

Step-by-step explanation:

1.25, -0.5, -5.05

Based on the information given, the required equation of parabola will be y= -3x² - 14x + 12.

The parabola passes through the points (-1, 23), (1, -5), (3, -57). Let the equation of the parabola be y = ax² + bx + c.

For point (-1, 23), this will be:

23 = a(-1)² + b(-1) + c

23 = a - b + c ..... equation i

For point (1, -5), this will be:

-5 = a(1)² + b(1) + c

-5 = a + b + c .... equation ii

For point (3, -57), this will be:

-57 = a(3)² + b(3) + c

-57 = 9a + 3b + c .... equation iii

From equation i, 23 = a - b + c

Therefore, c = 23 - a + b .... equation iv

Substitute c into equation ii

-5 = a + b + 23 - a + b

-5 = 2b + 23

2b = -23 - 5.

2b = -28

b = -28/2 = -14

Substitute c into equation iii

-57 = 9a + 3b + 23 - a + b

-80 = 8a + 4b.

-80 = 8a + 4(-14)

-80 = 8a - 56

8a = -80 + 56

8a = -24

a = -24/8 = -3

Therefore, the value of c will be:

c = 23 - a + b

c = 23 -(-3) + (-14)

c = 23 + 3 - 14

c = 12

In conclusion, the required equation of parabola will be y = -3x² - 14x + 12.

Step-by-step explanation:

Answer:

h=3/4

Step-by-step explanation:

19=h4+16

19-16=h4+16-16

3=h4

3/4=h4/4

3/4=h

h=3/4

Answer:

h = 3/4 or as a decimal it would be 0.75

Step-by-step explanation:

19 = h × 4 + 16

Reorder the terms

Use the communative property to reorder the terms

19 = 4h + 16

19 = 4h + 16

Move the terms

Move the variable to the left - hand side and change its side

19 - 4h = 16

Move the constant to the right - hand side and change its sign

-4h = 16 - 19

-4h = 16 - 19

Calculate

calculate the difference of 16 minus 19

-4h = -3

-4h = -3

Divide both sides of the eqaution by -4

Therefore your answer is h = 3/4 or if you want a decimal simplify 3/4 by dividing 3 and 4, which gives you 0.75

The range is:

Answer:

The perimeter of the square is 10 cm.

The area of the square is 6.25 cm.

Step-by-step explanation:

To find perimeter, add all the sides.

2.5 + 2.5 + 2.5 + 2.5 = 10

To find area, multiply the length by the width. Since Nadia drew a square, all the sides will have the same measurement (2.5 cm, in this case). So, simply multiply 2.5 by 2.5, knowing that the length and width of the square are the same size.

2.5 × 2.5 = 6.25

The area of Square is 6.25 cm² and Perimeter of Square is 10 cm.

The Area of Square is the product if its side

i.e., Area of square = side x side

and, perimeter of square = 4 x side

Given:

Side of Square= 2.5 cm

then , area of Square= side x side

                                   = 2.5 x 2.5

                                   = 6.25 cm²

and, Perimeter of Square= 4 x side

                                   = 4 x 2.5

                                   = 10 cm

Answer:

Y = 58

X = 66

Step-by-step explanation:

So the markers mean that those sides of the triangle are congruent. Because of this, we know that the angles opposite from those sides are equal as well.

In the big triangle, Y will be equal to the empty angle. You can then use:

180 = 64 + 2*Y

Then, solving for Y, you get:

Y = (180-64)/2

Y = 58

You can use the same idea for the smaller triangle. The empty angle will be the same as the angle marked as 57.

180 = 57*2 + X

Then, solving for X, you get:

X = 180 - 57*2

X = 66

srry if im wrong

Let me first ask this :

how do u find the midnumber of 1 and 3 ?

( 1 + 3 ) ÷ 2 =

4 ÷ 2 =

2

_________________________________

It is the exact way we do to find the midpoint of a line ; have a look :

The midpoint of AB is P thus :

( Point A + Point B ) ÷ 2 = Point P

Suppose that we have point B as ( x , y ) then :

[ ( 2 , 3 ) + ( x , y ) ] ÷ 2 = ( 6 , - 1 )

Now we add the same components of points A and B together, that is, we add the first component A to the first component B and replace the first component, and so we add the second component A to the second component B. And replace the second component :

[ ( 2 + x , 3 + y ) ] ÷ 2 = ( 6 , - 1 )

( 2 + x/2 , 3 + y/2 ) = ( 6 , - 1 )

Well now we have a draw so the first components of both sides of the draw must be equal Also, the second components of the two sides of the equation must be equal , thus :

2 + x/2 = 6

Multiply both sides by 2

2 × ( 2 + x )/2 = 2 × 6

2 + x = 12

Subtract both sides 2

2 - 2 + x = 12 - 2

3 + y/2 = - 1

Multiply both sides by 2

2 × ( 3 + y )/2 = 2 × ( - 1 )

3 + y = - 2

Subtract both sides 3

3 - 3 + y = - 2 - 3

Solving the quadratic equation, it is found that the duck was underwater for two seconds.

The path of the duck after x seconds is modeled by:

[tex]y = 2x^2 - 4x[/tex]

It is a concave up parabola, thus, the negative values of y, when he is underwater, are between the roots.

To find the roots:

[tex]y = 0[/tex]

[tex]2x^2 - 4x = 0[/tex]

[tex]2x(x - 2) = 0[/tex]

[tex]2x = 0 \rightarrow x = 0[/tex]

[tex]x - 2 = 0 \rightarrow x = 2[/tex]

2 - 0 = 2, thus, the duck was underwater for two seconds.

Step-by-step explanation:

Answer:

Cancellation it enables us to eliminate or get rid of one of the variables, so we can solve a more simplified equation.

Some textbooks refer to the elimination method as the addition method or the method of linear combination.

This is because we are going to combine two equations with addition!

Step 1

First, we align each equation so that like variables are organized into columns.

Step 2

Second, we eliminate a variable.

If the coefficients of one variable are opposites, you add the equations to eliminate a variable, and then solve.

If the coefficients are not opposites, then we multiply one or both equations by a number to create opposite coefficients, and then add the equations to eliminate a variable and solve.

Step 3

Thirdly, we substitute this value back into one of the original equations and solve for the other variable.

Example of how to apply the elimination method for solving systems of equations is attached.
