Corey has 140 marbles. He gives 16 to his younger brother. He divides the rest equally into four bags. How many go in each bag?

If f(x) = 4x + 21 and g(x) = 2x + 2 what is f[g(7)]

Nana76 [90]

Answer:

we conclude:

$f(g(7)) =85$

Step-by-step explanation:

Given

$f(x) = 4x + 21$

$g(x) = 2x + 2$

To determine

$f(g(7)) =?$

In order to determine f(g(7)), the first step we need to do is to determine g(7)

so substitute x = 7 in g(x) = 2x + 2

$g(x) = 2x + 2$

$g(7) = 2(7) + 2$

$g(7) = 14 + 2$

$g(7) = 16$

so now we have

$f(g(7)) =f(16)$

The next step to do is to substitute x = 16 in f(x) = 4x + 21

$f(x) = 4x + 21$

$f(16) = 4(16) + 21$

$f(16) = 64 + 21$

$f(16) = 85$

so we have

$f(g(7)) =f(16)=85$

Therefore, we conclude:

$f(g(7)) =85$

PLEASE HELP NEEDS TO BE DONE TONIGHT HELP PLEASE ASAP!

Levart [38]

Answer:

Variable

Variable expression

Number

Explanation:

A literal equation contains numbers, letters, and signs.

The letters represent variables, the numbers are constants, and the sign express relations, like equal (=), less than (<), and greater than (>).

You use the signs to make equations or inequalities.

Algebra is the use of mathematical rules applied to literal expressions. You can add, subtract, multiply and divide literal, expressions, like in arithmetic, following some rules.

To rewritte a literal equation in terms of a specific variable, you may need to divide by another variable, a variable expression, or a number, but never by an inequality sign.

Here you have one example for each case:

1. Dividing by another variable.

$x^2y^5=100\\\\\\ \dfrac{x^2y^5}{y^5}=\dfrac{100}{y^5}\\ \\ \\ x^2=\dfrac{100}{y^5}$

2. Dividing by a variable expression.

$x^2(z^3+y^5)=100\\\\\\ \dfrac{x^2(z^3+y^5)}{(z^3+y^5)}=\dfrac{100}{(z^3+y^5)}\\ \\ \\ x^2=\dfrac{100}{(z^3+y^5)}$

3. Dividing by a number:

$200x^2=100\\\\\\ \dfrac{200x^2}{200}=\dfrac{100}{200}\\ \\ \\ x^2=\dfrac{100}{200}\\ \\ \\ x^2=0.5$

As said above, you cannot divide by an inequality sign.

Find the midpoint M of the line segment joining the points C = (-1, -1) and D = (5, -5).

Nadusha1986 [10]

Answer:

The midpoint between the joining points C and D is (2, -3)

Step-by-step explanation:

How to find a midpoint

1: Label the coordinates(x₁,y₁) and (x₂,y₂).

2: Input the values into the formula.

3: Add the values in the parentheses and divide each result by 2.

4: The new values form the new coordinates of the midpoint.

Suppose we have a line segment and want to cut that section into two equal parts. To do so, we need to know the center. We can achieve this by finding the midpoint. You could measure with a ruler or just use a formula involving the coordinates of each endpoint of the segment. The midpoint is simply the average of each coordinate of the section, forming a new coordinate point. We shall illustrate this below.

Midpoint formula

If we have coordinates (x₁,y₁) and (x₂,y₂), then the midpoint of these coordinates is determined by (x₁ + x₂)/2, (y₁ + y₂)/2. This forms a new coordinate you can call (x₃,y₃). It is possible to divide a line segment into any given ratio, not just 1:1.
