If you would like to solve the inequation 4 * x - 4 - 3 * x > 13 - 7 * x - 1 + 8, you can do this using the following steps:

4 * x - 4 - 3 * x > 13 - 7 * x - 1 + 8
4 * x - 3 * x + 7 * x > 4 + 13 - 1 + 8
8 * x > 24 /8
x > 24/8
x > 3

The correct result would be x > 3.

Lin is running on a track. Lin runs 5 laps around a track in 6 minutes. How many laps per minute is that? (Find both Unit Rates)

grandymaker [24]

They got the 1.2 minutes by taking the total number of minutes (6) and dividing them by the number of laps run (5). So 6 divided by 5 gives you the 1.2.

Write an inequality that best matches this description

Citrus2011 [14]

Answer:

$x \geq 3(y + z)$

Step-by-step explanation:

I am going to say that:

Mary's amount is x.

Ashley's amount is y.

Oscar's amount is z.

Mary has at least 3 times the amount of cash that ashley and oscar have combined

Ashley's and Oscar's combined amount is y + z.

3 times this amount is 3(y + z).

At least 3 times means that z is equal or greater than 3(y + z).

So

$x \geq 3(y + z)$

Karen, James, Frank, and Dan were left an inheritance by their late grandfather. If Karen receives one-eighth of the inheritance

pashok25 [27]

Count what fraction receive Karen, James and Frank in total:

since

Karen receives - $\frac{1}{8}$ ,

James receives - $\frac{1}{4}=\frac{2}{8}$ ,

Frank receives - $\frac{3}{8}$ ,

then $\frac{1}{8} +\frac{2}{8} +\frac{3}{8} =\frac{1+2+3}{8}=\frac{6}{8} =\frac{2\cdot 3}{2\cdot 4} =\frac{3}{4}$ .

All inheritance is the whole 1, then for Dan remains $1-\frac{3}{4} =\frac{4}{4} -\frac{3}{4} =\frac{4-3}{4} =\frac{1}{4}$ .

Answer: Dan receives one quarter of the inheritance.

2b.) What transformation of f(x) does y correspond to?

kkurt [141]

Answer:

The transformation is " a horizontal translation 4 units to the right " ⇒ (d)

Step-by-step explanation:

Let us revise the translation of a function

If the function f(x) translated horizontally to the right by h units, then its image is g(x) = f(x - h)

If the function f(x) translated horizontally to the left by h units, then its image is g(x) = f(x + h)

If the function f(x) translated vertically up by k units, then its image is g(x) = f(x) + k

If the function f(x) translated vertically down by k units, then its image is g(x) = f(x) - k

Let us look at the graph and choose some points on the f(x) and find their images on y

∵ Point (1, 2) lies on f(x)

∵ Point (5, 2) lies on y

∵ Point (3, 8) lies on f(x)

∵ Point (7, 8) lies on y

→ There is no change in the y-coordinates of the points, the change

only in the x-coordinates

∴ The translation is horizontally

∵ 5 - 1 = 4 units ⇒ positive value means to right

∴ f(x) is translated 4 units to the right

∴ The answer is " a horizontal translation 4 units to the right " (d)
