Answer:

The Distributive Property is used, which consists of multiplying the factor by each of the addends.

2x (x-4) = 2x.x-2x.4 = 2 x 2 -8x

It is better to understand what you are doing. Hope this can help you :)

Answer:

slope: $\frac{3}{4}$ ; y-intercept: 1

Step-by-step explanation:

First, you must rearrange the function into y = mx + b form:

2x + x = 4(y - 1)

Simplify both sides:

3x = 4y - 4

Subtract 3x and 4y from both sides:

-4y = -3x - 4

Divide both sides by -4:

y = $\frac{3}{4} x$ + 1

Now that it is in y = mx + b form, you can find the slope and y-intercept. In y = mx + b form, m is the slope and b is the y-intercept. Therefore:

m = $\frac{3}{4}$ = slope

b = 1 = y-intercept

An hour is 60 mins long. 30 mins is half of it. If we take 12 miles in an hour, divide it by 2, it will be 6 miles in 30 mins, and if we take 8 miles, divide it by 2, it would be 4 miles in 30 mins. Since the questions telling us how far apart are north cyclists, we’re adding 6 and 4 to get 10 miles. In conclusion, both cyclists are 10 miles apart. I might be wrong, but that’s the best I can do.

The point (-4‚-2) lies on a circle. What is the length of the radius of this circle if the center is located at (-8‚-10)

MAVERICK [17]

Answer:

Step-by-step explanation:

The length of the radius of the circle will be the distance between the two coordinates. Using the formula:

D = √(x₂-x₁)²+(y₂-y₁)²

Given the coordinates (-4‚-2) and (-8‚-10)

R = √(-8-(-4))²+(-10-(-2))²

R = √(-4)²+(-8)²

R = √16+64

R = √80

R = √16*5

R = 4√5

<em>Hence the length of the radius of this circle is 4√5</em>

I'm really confused about this. Probabilities have always been a pain for me and I really don't understand this

nordsb [41]

Answer:

Step-by-step explanation:

The first thing to notice is the question says it is given that the person is between the ages 23 and 60, so we only care about those people. So then we want to know how likely it would be to pick someone with over 50 messages a month. So what you would do is take the amount of people who are between 23 and 60 and send over 50 text messages, and divide that by the total amount of people 23-60 (since that is the pool of people we have). Doing so we find there is 229 people aged 23-60 which then makes the answer 157/229 or A.

Which fraction out of 5/8 and 7/11 is closest to 2/3?

Triss [41]

Well... hell, let's just convert them all with the same denominator then

hmmm let's see, we have the denominators of 8,11 and 3

so... we'll multiply the 5/8 times (11*3) or 33
and then we'll multiply 7/11 times (8*3) or 24
and then we'll multiply 2/3 times (8 * 11)

notice, we're simply using the other's denominator's product, to multiply the fractions... anyhow... let's check

$\bf \cfrac{5}{8}\cdot \cfrac{3\cdot 11}{3\cdot 11}\implies \cfrac{165}{264}
\\\\\\
\cfrac{7}{11}\cdot \cfrac{8\cdot 3}{8\cdot 3}\implies \cfrac{168}{264}
\\\\\\
\cfrac{2}{3}\cdot \cfrac{8\cdot 11}{8\cdot 11}\implies \cfrac{176}{264}\\\\
-------------------------------\\\\
\textit{now, which of }\cfrac{165}{264}\textit{ and }\cfrac{168}{264}\textit{ is closest to }\cfrac{176}{264}\quad ?$
