Answer:

The answer would not be A. It is B

Step-by-step explanation:

Because you are subtracting the equations, on the right side of the equal sign, you are subtracting -5 from 7. This is 7-(-5), which is equal to 7+5=12, not -12.

Determine the distance of the line segment whose endpoints<br> are (2, 3) and (2, 9)

Mnenie [13.5K]

Answer:

6 units

Step-by-step explanation:

Given:

(2, 3)
(2, 9)

To find the distance between two points, we need to use the distance formula:

$d = \sqrt{(x_{2}-x_1)^2 + (y_2-y_1)^2 }$

Plug in what you know:

$= \sqrt{(2-2)^2 + (9-3)^2 }$

Simplify:

$= \sqrt{(0)^2 + (6)^2 }$

Evaluate the exponents.

$= \sqrt{(0) + (36) }$

Add.

$= \sqrt{(36) }$

Evaluate the square root.

$= 6$

The distance between the two points is 6 units.

Which of the following has a graph that is a straight line? (4 points)

nlexa [21]

The equation 2 has a graph which is a straight line.

Why?

We can know which of the given equations has a graph which is a straight line just checking the exponents of the variables.

We must remember that every variable that has an exponent equal or higher than 2 (quadratic) will not have a straight line as a graphic.

So, checking the exponents from the given equations, we have:

$Equation_{1} =x^{3}=NotLinear\\Equation_{2}=x=Linear\\Equation_{3}=y^{2}=Quadratic\\Equation_{4}=x^{2}=Quadratic$

Hence, we can see that the only equation that has a linear term (straight line graph), is the second equation.

Have a nice day!

Select the three number bonds that represent factor pairs of the number 56. CLEAR CHECK Number bond: 1 times 56 = 56. Number bon

Ray Of Light [21]

Answer:

The answer is -

Number bond: 1 times 56 = 56.

Number bond: 4 times 14 = 56.

Number bond: 7 times 8 = 56.

Step-by-step explanation:

We can define a factor pair as a set of two factors, which, when multiplied together, give a particular product.

For example -

5 and 6 are factors of 30 because 5×6 = 30

Now,

Given -

Number bond: 1 times 56 = 56. ...................(1)

Number bond: 4 times 14 = 56. ...................(2)

Number bond: 5 times 6 = 56. ...................(3)

Number bond: 7 times 8 = 56. ...................(4)

In equation (1)

1 times 56 = 1×56 = 56

⇒1 and 56 are the factor pairs of 56

Satisfies

In equation (2)

4 times 14 = 4×14 = 56

⇒4 and 14 are factor pairs of 56

Satisfies

In equation (3)

5 times 6 = 5×6 = 30 ≠ 56

⇒5 and 6 are not factor pairs of 56

Not Satisfies

In equation (4)

7 times 8 = 7×8 = 56

⇒7 and 8 are factor pairs of 56

Satisfies

∴ we get

The answer is -

Number bond: 1 times 56 = 56.

Number bond: 4 times 14 = 56.

Number bond: 7 times 8 = 56.
