Answer:

The information with which the parabola is constructed is insufficient

Step-by-step explanation:

The vertex form of a quadratic equation is given as follows;

f(x) = a(x - h)² + k

The steps to draw the graph of a quadratic function given in vertex form, we are required to do the following;

1) Definition of the variables, (a, h and k) of the quadratic equation (given in vertex form)

The vertex of the quadratic equation in vertex form is (h, k)

2) Given that the vertex point is given, the vertex point is then plotted on the graph

3) Draw the parabola axis of symmetry that passes through the vertex point

4) Determine the direction to which the parabola opens from the sign of the variable a as follows;

i) When a is positive, the parabola opens upwards

ii) When a is negative, the parabola opens downwards

5) Determine if the parabola has x-intercepts and plot them

A parabola has x intercepts when;

i) The parabola opens downwards, that is, the variable, a, is negative and also the vertex (h, k) is above the x-axis or k is positive

ii) The parabola opens upwards, that is, the variable, a, is positive and also the vertex (h, k) is below the x-axis or k is negative

6)  Determine y-intercepts and plot them as follows;

At the y-intercept, x = 0, therefore;

f(x) = a(x - h)² + k

f(0) = a(0 - h)² + k = a·h² + k

6) If any additional points are required, they should plotted and then the graph of the function is then drawn making sure to be symmetrical about the vertex and to pass through all the plotted points.

Answer:

15) 1/3

18) 1/2

21) 25/26

Step-by-step explanation:

15) 2/6=1/3

18) 3/6=1/2

21) 25/26

Answer:

When p2 – 4p is subtracted from p2 + p – 6, the result is:

p2+p-6-(p2-4p)=p2+p-6-p2+4p=5p-6

To get p – 9, subtract from this result x:

5p-6-x=p-9

Solving for x:

5p-6-x+x-p+9=p-9+x-p+9

4p+3=x

x=4p+3

Answer:

1) When p2 – 4p is subtracted from p2 + p – 6, the result is 5p-6

2) To get p – 9, subtract from this result 4p+3

21

Step-by-step explanation:

-(-26) would be positive 26 because one negative multiplied by another negative equals a positive. We are left with -5+26 which would equal 21.

Answer:

Option 1

Step-by-step explanation:

look at the graph in bot cases y still positive in the upper part of the graph

only x moves from the right side to left side of the graph

Take one point A (2,2) to A'(-2,2)

from 2 to -2 (x-4=2-4=-2)

from 2 to 2 ( y still the same)

Answer:

a=5

Step-by-step explanation:

18=5a-2a+3

Combine like terms

18 = 3a +3

Subtract 3 from each side

18-3 = 3a+3-3

15 = 3a

Divide by 3

15/3 =3a/3

5 =a

Answer:

no

Step-by-step explanation:

y = x

Substitute the point into the equation

0=2

This is not true so the point is not a solution

Hey there! I'm happy to help!

The point (2,0) does not satisfy the equation y=x. That means that x and y have to be equal. 2 and 0 are not equal. A point like (4,4) would satisfy that.

Answer:

n + 6 = 7n

Step-by-step explanation:

"The sum of a number and six" would mean the number plus 6: n+6 and "is seven times the number" indicates that it would be equal to the product of 7 for n: 7n. According to this, the answer is that the translation of the sentence into an equation is: n+6=7n.

n − 6 = 7n is not right because the statement says the sum of a number and six.

7(n + 6) = n is not right because the statement indicates that seven multiplies n on the right side as it says seven times the number.

n = 7n + 6 is not right because the statement says the sum of a number and six which would be on the left side and that this would be equal to seven for n.

Answer:

The slope-intercept form of the equation of the line is [tex]y = -\frac{3}{5} \cdot x -4[/tex].

Step-by-step explanation:

We know that the slope-intercept form of the equation of the line is represented by:

[tex]y = m\cdot x + b[/tex]

Where:

[tex]x[/tex] - Independent variable, dimensionless.

[tex]y[/tex] - Dependent variable, dimensionless.

[tex]m[/tex] - Slope, dimensionless.

[tex]b[/tex] - y-Intercept, dimensionless.

From statement we find that [tex]m =-\frac{3}{5}[/tex]. If [tex]x = -5[/tex] and [tex]y = -1[/tex], the value of the y-intercept is:

[tex]-1 =-\frac{3}{5}\cdot (-5)+b[/tex]

[tex]-1 = 3 + b[/tex]

[tex]b = -4[/tex]

The slope-intercept form of the equation of the line is [tex]y = -\frac{3}{5} \cdot x -4[/tex].

Answer:

[tex]x = 6[/tex]

[tex]y = -7[/tex]

Step-by-step explanation:

We have the system of equations:

[tex]4x+2y=10\\x=y+13[/tex]

Let's solve by substituting. We know that [tex]x=y+13[/tex], so we can substitute [tex]y+13[/tex] in as [tex]x[/tex] in the equation [tex]4x+2y=10[/tex].

[tex]4(y+13) + 2y = 10[/tex]

Simplify this down so that we have [tex]y[/tex] on one side of the equation:

[tex]4y + 52 + 2y = 10\\\\6y + 52 = 10\\\\6y = -42\\\\y = -7[/tex]

Now that we know the value of [tex]y[/tex], we can substitute it in to the equation [tex]x = y+13[/tex] to find [tex]x[/tex].

[tex]x = -7+13\\\\x = 6[/tex]

Hope this helped!

Answer:  (6,-7)

Step-by-step explanation:

4x +2y = 10  

x = y + 13      Substitute the value of x into the first equation to solve for y.

4(y + 13) +2y = 10   apply the distributive property on the left side

4y + 52 + 2y = 10   Combine like terms on the left side

6y + 52 =  10    Subtract  52 from both sides

       -52     -52

6y = -42  

y= -7  

The value of y so input it into one of the equations to solve for x

4x + 2(-7) = 10  

4x - 14  =  10

       +14    +14

4x = 24

Answer:the answer is A

Step-by-step explanation:

The vertex and x-intercepts of the graph of the function y = x²- 2x-35 is (1, -36) and intercepts: x = 7,-5, option A is correct.

A quadratic equation is a second-order polynomial equation in a single variable x , ax²+bx+c=0. with a ≠ 0 .

The x-coordinate of the vertex can be found using the formula x = -b/2a, where a and b are the coefficients of the x² and x terms, respectively. In this case, a = 1 and b = -2, so x = -(-2)/(2×1) = 1.

Lets find the y-coordinate of the vertex.

To find the y-coordinate of the vertex, we substitute the x-coordinate we found in step 1 into the equation and evaluate.

y = (1)² - 2(1) - 35 = -36

So the vertex is at (1, -36).

Now find the x-intercepts.

To find the x-intercepts, we set y = 0 and solve for x.

0 = x² - 2x - 35

This equation can be factored as (x - 7)(x + 5) = 0.

So the x-intercepts are at x = 7 and x = -5.

Therefore,  the vertex and x-intercepts of the graph of the function y = x²- 2x-35 is (1, -36) and intercepts: x = 7,-5, option A is correct.

Hi there!

Your answer is:

Median: 23.5

Mean: 25

Step-by-step explanation:

The mean is the average of all the numbers in your dataset. You determine this by adding all the numbers together and dividing by the # of numbers in your set!

35+28+19+18 = 100.

100/4 = 25

The median is the middle number of your data set! This is determined by counting off the numbers from each side of the equation after setting them in order from least to greatest. If there are 2 remaining, you must find the average of those!

35 , 28, 19 , 18 from least to greatest is

18, 19, 28, 35

Answer:

it will cost him $2204 to recarpet the room.

Step-by-step explanation:

The floor of the room is rectangular. The formula for determining the area of a rectangle is expressed as

Area = length × width

The rectangular hotel room is 4 yards by 7 yards. It means that the area of the rectangular floor would be

Area = 4 × 7 = 28 square yard.

If the cost of the carpet $58.00 per square yard, the total that it will cost to recarpet the room would be

38 × 58.00 = $2204
