Answer:

Step-by-step explanation:

Vertex form is accomplished by completing the square on the quadratic. Do this by first setting the parabola equal to 0 then moving the constant over to the other side:

[tex]x^2+6x=-9[/tex]

Now take half the linear term, square it, and add it to both sides. Our linear term is 6. Half of 6 is 3, and 3 squared is 9:

[tex]x^2+6x+9=-9+9[/tex]

The reason we do this is to create a perfect square binomial on the left:

[tex](x+3)^2=0[/tex] (obviously the 0 results from the addition of 9 and -9). Move the 0 back over to the other side and set the quadratic back equal to y:

[tex](x+3)^2+0=y[/tex]

This gives you a vertex of (-3, 0), which is a minimum value, since the parabola opens upwards.

Answer:

42

Step-by-step explanation:

Add 41.3 + 0.7

First, calculate the TENTH (not tens) place of both the decimals.

3+7=10

We shall bring over the 1 in the tens place of 10, as the maximum number you can write in a place is 9.

Now, add the whole numbers.

41+0+1=42

Since the whole number is 42, and the tenth place is filled with the number 0, the answer is simply 42.

Answer:

Yes

Step-by-step explanation:

Linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx. A linear function has one independent variable and one dependent variable. To see if a table of values represents a linear function, check to see if there's a constant rate of change. If there is, you're looking at a linear function!

m=1*(24+-1*15)/(8+-1*5)  | add 24 to -15

m=1*9/(8+-1*5)  | add 8 to -5

*m=1*9/(8+-5)  | Divide 9 by 3

m=1*3  

Calculate the y-axis intercept b by inserting:

General form of the linear function: f(x)=mx+b

Insert 3 for m, 5 for x and 15 for f(x).

 | Multiply 3 by 5

15=3*5+1*b  | Swap both sides of the equation.

1*b+15=15  | -15

1*b=0  

So, the y-axis intercept is at 0

Therefore, the equation of the function is f(x)=3*x+0

Answer:

  y = (x + 7)(x − 7)

Step-by-step explanation:

If 'a' is a zero, then (x -a) is a factor.

If 7 and -7 are zeros, then (x -7) and (x +7) are factors. The appropriate choice is ...

  y = (x + 7)(x − 7)

Answer:

D

Step-by-step explanation:

y = (x+7) (x-7)

Answer:

Each apple costs 0.85 and each orange costs 0.65.

Step-by-step explanation:

5a+o = 4.90

3a+6o = 6.45

Multiply the first by 3 and the second by 5 and subtract the second from the first.

15a+3o = 14.70

15a+30o = 32.25

27o = 17.55

o=0.65

Plug back in the first.

5a+0.65=4.90

5a=4.25

a=0.85

Answer: 18

Answer:

$0.1

Step-by-step explanation:

From the information given, you know that Mikayla and Weatha spent the same amount of money and because of that you can write the following:

6.25+75x=4.75+90x, where x is the price of a small piece of candy

Now, you can solve for x:

6.25-4.75=90x-75x

1.5=15x

x=1.5/15

x=0.1

According to this, the answer is that a small piece of candy costs $0.1.

Answer:

x<3 cm²

Step-by-step explanation:

area of square: 4x

area of triangle: 1/2 (4x)=2x

total area: 6x

If the total area is less than 18:

6x<18

x<3

Inequality represents the missing dimension x is x<3.

Given that, the dimensions of the rectangle are length=4 cm and width=x cm.

The dimensions of the triangle are hieght=4 cm and base=x cm.

Inequalities are mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

Now, the area of a figure> the area of a rectangle + the area of  a triangle

18 cm²>length×width+1/2 × base × height

⇒18 cm²>4×x+1/2 × 4 × x

⇒18>4x+2x

⇒18>6x

⇒x<3

Therefore, inequality represents the missing dimension x is x<3.
