Step-by-step explanation:

Remark

Start with the meaning of g[f(x)]. This when you write g(x), where ever you see and x in g(x), put in an f(x)

g(f(x))

g(x)= x + 1                     Substitute f(x) for x

g(f(x)) = f(x) + 1              Substitute x^2 for f(x)  

g(f(x)) = x^2 + 1              

g(f(-2)) = (-2)^2 + 1        Substitute -2 for x

g(f(-2)) = (4) + 1              

g(f(-2)) = 5          

Answer:

n=-2

Step-by-step explanation:

1−(2n+9)=4(1−2)

1+−1(2n+9)=4(1−2)

1+−1(2n)+(−1)(9)=4(1−2)

1+−2n+−9=4(1−2)

1+−2n+−9=−4

(−2n)+(1+−9)=−4

−2n+−8=−4

−2n−8=−4

−2n−8+8=−4+8

−2n=4

Divide both sides by -2

-2n/2=4/-2

n=-2

Answer:

n = -2

Step-by-step explanation:

remove () from equation so its 1-2n-9=4× -1

calculate the differences and multiply

-8-2n=-4

move the constant to the right of the equation  -2n=-4+8

calculate the sum -2n=4 divide both sides of equation by -2  

and boom n=-2

Answer: Newton's law of universal gravitation is represented by F = GMm/r2 where F is the magnitude of the gravitational force exerted by one small object on another, M and m are the masses of the objects, and r is a distance. Force has the SI units kg · m/s2.

Answer:

We conclude that the solution to the system of linear equations will be:

(x, y) = (-4, 0)

Step-by-step explanation:

Please check the attached diagram.

In the attached diagram:

From the diagram, we can easily identify that both lines meet or intersect at x = -4 and y = 0.

In other words, the point of intersection of the system of equations is:

(x, y) = (-4, 0)

We know that the point(s) of the intersection of the system of equations represents the solution of the system of equations.

Therefore, we conclude that the solution to the system of linear equations will be:

(x, y) = (-4, 0)

Answer:

=93

Step-by-step explanation:

30−(7)(−9)

=30−(−63)

=93

Answer:

93

Step-by-step explanation:

Substitute x = -9 into the equation:

30 - 7 * (-9)

= 30 + 63

= 93

the product is 6 3/12

or 6 wholes and 3 over 12  (6[tex]\frac{3}{12}[/tex])

Answer:

B

Step-by-step explanation:

If you think of it as a graph the y intercept is -430, meaning that after 0 minutes it's at -430 (it started at -430).

Because you multiply the number of minutes by 38, that means it ascends by 38 meters every minute.

Answer:

-84i - 12i

Step-by-step explanation:

The distributive property is: a(b+c) = ab + ac

In this case, we have -6i(-14i+2)

-6i = a

-14i = b

2 = c

-6i(-14i+2) = -6i(-14i) + -6i(2)

= 84i^2 - 12i

= -84 - 12i

Answer:

84-12i

Step-by-step explanation:

-6i(-14i+2).

since we can’t add the numbers in the (), we multiply -6i to 14i and 2.

minus times minus equals positive +.

minus times positive equals minus, same with positive times minus.

positive times positive numbers equal positive.

with this, -6i times -14i equals +84 although we don’t need to put the +.

then -6i times +2 equals -12i. We have to put the i in 12i because the i is in -6i, plus that is what we are multiplying with. So the equation would be..

+84+(-12i)

= 84 - 12i

Hope this helps :)

Answer:

The value of a that can substituted into equation D = 4b + 5

Step-by-step explanation:

Given that:

a = 4b + 5   ---- (equation c)

a = 6b - 2   ---- (equation d)

Replace the value of a = 4b + 5 into "a" in (equation d) to solve the system of equations.

So;

4b + 5 = 6b -2

5 + 2 = 6b -4b

7 = 2b

b = 7/2

b = 3.5

Answer:

The correct answer is 4b + 5 ( A )

Step-by-step explanation:

Took the test and got it right trust me its A

Answer:

[tex]y = 2x-5[/tex]

Step-by-step explanation:

Given

[tex](x_1,y_1) = (3,1)[/tex]

Parallel to: [tex]y = 2x + 3[/tex]

Required

Determine the line equation

First, we calculate the slope of [tex]y = 2x + 3\\\\[/tex]

For an equation in the form [tex]y = mx + c[/tex]

[tex]m = slope[/tex]

So, by comparison:

[tex]m = 2[/tex]

The line equation is then calculated:

[tex]y - y_1 = m(x - x_1)[/tex]

Where [tex](x_1,y_1) = (3,1)[/tex] and [tex]m = 2[/tex]

So, we have:

[tex]y - 1 = 2(x - 3)[/tex]

[tex]y-1 = 2x-6[/tex]

[tex]y = 2x-6+1[/tex]

[tex]y = 2x-5[/tex]

Answer:

-3x/2

Step-by-step explanation:

Given:

Fractions [tex]\dfrac{1}{9},\dfrac{2}{9},\dfrac{3}{9}[/tex] etc.

To find:

What happens with the “ninth” fractions.

Solution:

We have, the values of [tex]\dfrac{1}{9},\dfrac{2}{9},\dfrac{3}{9}[/tex] are

[tex]\dfrac{1}{9}=0.11111...[/tex]

[tex]\dfrac{2}{9}=0.22222...[/tex]

[tex]\dfrac{3}{9}=0.33333...[/tex]

Clearly we can spot a pattern, because after decimal the numerator digit of fraction is repeating.

Similarly,

[tex]\dfrac{9}{9}=0.99999...[/tex]

Therefore, the decimal value of [tex]\dfrac{9}{9}[/tex] is 0.99999..., which is approximately 1.

Answer:

[tex]3x^{2}+26x+48[/tex]

Step-by-step explanation

Just in case you need to solve it, I'm using distributive property:

[tex]3x(x+6) + 8(x+6)[/tex]

[tex]3x^{2}+18x+8(x+6)[/tex]

[tex]3x^{2}+18x+8x+48[/tex]

[tex]3x^{2}+26x+48[/tex]

Answer:

64, 40 + 24

Step-by-step explanation:

5:3

a - b = 16

a = 5k

b = 3k

5k - 3k = 16

2k = 16

k = 8

a = 40

b = 24

a + b = 64
