I need help with this question

Answer:

Step-by-step explanation:

(1, 4)

(-1, 0), (3, 0)

The coordinate of the turning point is (1,4) and the coordinates of the roots are (-1,0) and (3,0)

This is the vertex of the equation.

The equation is the given as:

y = 3 + 2x - x^2

According to the graph, the vertex is at the coordinate (1,4)

Hence, the coordinate of the turning point is (1,4)

The equation is the given as:

3 + 2x - x^2 = 0

According to the graph, the equation crosses the x-axis at (-1,0) and (3,0)

Hence, the coordinates of the roots are (-1,0) and (3,0)

Answer:

The number of skateboards of each color is 11 and 4

Step-by-step explanation:

Let x represent blue skateboards and

y represent red skateboards.

From the question, the total number of skateboards is 15, that is,

x + y = 15 ...... (1)

and their product is 44, that is,

xy = 44 ...... (2)

From equation (1),

x + y = 15

We can write that

x = 15 - y ...... (3)

Substitute this into equation (2)

xy = 44

(15-y)y = 44

15y -y² = 44

Then,

y² - 15y + 44 = 0

Solve quadratically

y² -4y -11y + 44 = 0

y(y-4) -11(y-4) = 0

(y-11)(y-4) = 0

y-11 = 0 OR y-4 = 0

y = 11 OR y = 4

Put the values of y into equation (3) for x

x = 15 - y

When y = 11

x = 15 - 11

x = 4

and when y = 4

x = 15 -4

x = 11

(4,11) and (11,4)

It is either 4 blue and 11 red skateboards OR 11 blue and 4 red skateboards.

Hence, the number of skateboards of each color is 11 and 4.

Answer: I am pretty sure the mistake would be where he put the variable k.

Step-by-step explanation:

You know the variable equals 8 because 2x8=32. You can change the equation to 2(32+2) Therefore, the variable diesnt equal 2, so 32=2(k+4) doesnt work. Hope this helps!!

Distributing

Step-by-step explanation:

The first step is to get the x's out of parenthesis. Distribute the 2 into the (x-4), and the -3 into (x+2).

ex. 2(x-4) = -3(x+2)

distribute: 2x-8= -3x+6

Then solve for x.

Answer:

1. $17.5

3. $16.1

Step-by-step explanation:

1. $700x1.025=717.5

717.5-700=17.5

3. $14x1.15=16.1

Answer and Step-by-step explanation:

First, we find the area of one area of a face on the cube.

6.5 × 6.5 = 42.25

Now, we times 42.25 by 6, since there are 6 faces on a cube.

42.65 × 6 = 253.5

The answer is 253.5

[tex]f(d) = 15 + 3d[/tex]

Step-by-step explanation:

Given

[tex]a = 15[/tex] --- day 1

[tex]Rate = 3[/tex] -- i.e. triples daily

Required

Determine the function f(d)

The number of customers on a particular day is:

Customers = Day 1 + Rate * Number of days

Represent as a function:

[tex]f(d) = a + Rate* d[/tex]

Where d is the number of days.

So, we have:

[tex]f(d) = 15 + 3* d[/tex]

[tex]f(d) = 15 + 3d[/tex]

Answer:

Multiply both sides by -2 and reverse the inequality symbol.

Step-by-step explanation:

To isolate w, multiply both sides by the reverse of -1/2 (because -1/2*2=1 ), which is -2

When multiplying or dividing by negatives, you must reverse the inequality symbol as well.

To isolate the variable,  you multiply both sides by -2 and reverse the inequality symbol.

Isolation of variables means making the variable the subject of the formula from the given expression.

Given the inequality expression -1/2 w  < 12

To make w the subject of the formula, we will have to multiply both sides by -2 to have;

-1/2 w * -2 >  12 * -2
w > -24

Hence to isolate the variable,  you multiply both sides by -2 and reverse the inequality symbol.

Answer:

The length of the diagonal is x√10

Step-by-step explanation:

Here, we want to find the length of the diagonal

The diagonal will represent the hypotenuse of a triangle formed with the width and length of the triangle being the measure of the other sides

Mathematically, we then apply Pythagoras’ theorem to get this

we have this as that the square of the diagonal equals the sum of the squares of the two other sides
