Take a piece of paper and write a line with dashes having a number below it until 50. Then Go to 34 on your number line and then go backwards by 28. (34 - 28) the answer should be 6. The number line helps you count steps forward/backwards. :)

A number line can be used to find the difference between 34-28 because you can count each space in-between each number (6).

Two fair dice are rolled. What is the probability that the sum or product of the two numbers rolled is either 6 or 7?

zlopas [31]

Answer:

Rolling a 7 is 1/6

Which expression represents the same solution as (4) (negative 3 and StartFraction 1 over 8 EndFraction? (4) (negative 3) + (4)

elena-s [515]

Answer:

Option B.

Step-by-step explanation:

The given expression is

$(4)(-3\dfrac{1}{8})$

We need an expression Which represents the same solution as the given expression.

It can be written as

$(4)[-(3+\dfrac{1}{8})]$

$(4)[-3-\dfrac{1}{8}]$

$(4)(-3)+(4)(-\dfrac{1}{8})$

Since $(4)(-3)+(4)(-\dfrac{1}{8})$ is equivalent to given equation, therefore this equation represents the same solution as the given expression.

Hence, option B is correct.

Randolph is creating rectangle WXYZ so that WX has an equation of y = 1 over 4x + 4. Segment XY must pass through the point (−2,

Sliva [168]

Answer:

The correct option is;

c.) y - 6 = -4(x - (-2))

Step-by-step explanation:

We note that the figure Randolph is creating is a rectangle, therefore, we have;

$\overline{WX}\perp \overline{XY}$ , therefore, we have;

$\overline{WX} = \dfrac{1}{4} x + 4$

∴ Slope $\overline{WX}$ = 1/4

$\overline{XY}$ must pas through the point (-2, 6)

Given that $\overline{WX}\perp \overline{XY}$ , we have;

$Slope \ \overline{XY} = \dfrac{-1}{Slope \ \overline{WX}}$

$\dfrac{y - 6}{x - (-2)} = -1/\dfrac{1}{4} = -4$

y - 6 = -4(x - (-2))

Therefore, the correct option is c.) y - 6 = -4(x - (-2)).
