Answer:

we would add [tex]\:\left(\frac{1}{2}\right)^2\:[/tex] or 1/4 to make the expression a perfect square.

Step-by-step explanation:

Given the expression

[tex]x^2+x[/tex]

[tex]\mathrm{Write}\:x^2+x\:\mathrm{in\:the\:form:\:\:}x^2+2ax+a^2[/tex]

[tex]2a=1[/tex]

Divide both sides by 2

[tex]\frac{2a}{2}=\frac{1}{2}[/tex]

[tex]a=\frac{1}{2}[/tex]

as

[tex]x^2+2ax+a^2=\left(x+a\right)^2[/tex]

[tex]\mathrm{Add\:}\:\left(\frac{1}{2}\right)^2\:[/tex]

[tex]x^2+1x+\left(\frac{1}{2}\right)^2=\left(x+\frac{1}{2}\right)^2[/tex]

Thus, we would add [tex]\:\left(\frac{1}{2}\right)^2\:[/tex] or 1/4 to make the expression a perfect square.

Answer:

For me when I am finding the slope I actually use the slope formula [tex]\frac{y2-y1}{x2-x1}[/tex].

Step-by-step explanation:

Step 1 you have to find the x and y

Step 2: Use the slope formula

Step 3: Subtract y2 and y1 to get your answer

Step 4: Subtract x2 and x1 to get your answer

Step 4: If your answer is easy to divide  simplify it, if not leave it as it is

That's all I know

I hope this helps :)

Answer:

Choose two sets of data (x and y values).  Calculate the difference between the two y values.  Calculate the difference between the corresponding two x values.  Slope is the difference in y values / difference in x values.

Answer:

it's 42 my bad...

Step-by-step explanation:

Answer:

Choice C 42 in^2

Step-by-step explanation:

Area of a triangle= 1/2(b)(h)

= 1/2(3)(6)

= 9

Since there is two triangles we can do:

9(2) = 18

Area of a rectangle = (b)(h)

= (4)(6)

= 24

24+18 = 42 in^2

Answer:

A. 94.37 seconds

B. 0.48 seconds

Step-by-step explanation:

Total distance = 50 meters

First trial = 32.15 seconds

Second trial = 31.67 seconds

Third trial = 30.55 seconds

A. What is Todd's combined time for all three trials

Todd's combined time for the three trials = First trial + Second trial + Third trial

= 32.15 seconds + 31.67 seconds + 30.55 seconds

= 94.37 seconds

B. How much faster was Todd's second trial than his first trial?

Second trial = 31.67 seconds

First trial = 32.15 seconds

Time taken for first trial - Time taken for second trial -

= 32.15 seconds - 31.67 seconds

= 0.48 seconds

Todd's second trial was 0.48 seconds faster than his first trial

Answer:

A = h²

Step-by-step explanation:

the area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )

here b = 2h , then

A = [tex]\frac{1}{2}[/tex] × 2h × h = h × h = h²

Answer:

Finding the y value is easy if you know the slope of the line and the x coordinate. Review the equation for the slope of a line. The equation for finding the slope is: m = [y1 - y2] / [x1 - x2]. If you know x, you can solve for y to find the y value for the slope of the line.

Step-by-step explanation:

Step 1: Define Equation

-4(x + 2) = 4(2 - 2x)

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Here we see that -24 does equal -24.

∴ x = 4 is the solution to the equation.

Answer:

The coordinates of the midpoint of the line segment p(-5,-1) Q(6,-2) would be: (1/2, -3/2)

Step-by-step explanation:

Given

[tex]\mathrm{Midpoint\:of\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-5,\:-1\right),\:\left(x_2,\:y_2\right)=\left(6,\:-2\right)[/tex]

[tex]=\left(\frac{6-5}{2},\:\frac{-2-1}{2}\right)[/tex]

Answer:

Step-by-step explanation:

Alexis is X years old

Josiah is X + 5 years old

in 7 years:

Alexis is x + 7 years old

Josiah is x + 5 + 7 => x + 12 years old

Sum of their ages is 85 :

x + 7 + x + 12 = 85

2x + 19 = 85

2x = 85 - 19 = 66

x = 66/2 = 33 => Alexis age

Josiah is x + 5 = 33 + 5 = 38 years old

The pound that he ad will be 19/30 pounds.

From the information, it was stated that Sean bought 4/5 of a pound of cherries and then he ate 1/3 of a pound of them.

He also found out that he had 1/6 of a pound of cherries in his cupboard.

Therefore, the total will be:

= (4/5 - 1/3) + 1/6

= 24/30 - 10/30 + 5/30

= 19/30

Therefore, the pound that he ad will be 19/30 pounds.

Answer:

[0, ∞)

Step-by-step explanation:

The domain is the x values in a function. As you can see from the graph, the function touches zero (touching meaning the value zero is bracketed) and goes to infinity (infinity is parenthesis).

If a value is included it is bracketed. If it is not included it is used with parenthesis (infinity cannot be reached to it is used with parenthesis).

Answer:

a = 3

Step-by-step explanation:

Calculate the distance d using the distance formula and equate to 4

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = (2, - 1) and (x₂, y₂ ) = (2, a)

d = [tex]\sqrt{(2-2)^2+(a+1)^2}[/tex] = [tex]\sqrt{0+(a+1)^2}[/tex] = [tex]\sqrt{(a+1)^2}[/tex] = a + 1 then

a + 1 = 4 ( subtract 1 from both sides )

a = 3
