What is the solution to this equation x+12=-5

Mathematics

X + 12 = -5

To find the solution of this problem, we need to get x alone on one side, and then simplify if needed.

With this information, we are ready to solve.

Currently, our equation is:

x + 12 = -5
Remember, we are trying to get x by itself.
Also, take note that when you do something to one side of the equation, you must do it to the other side as well.

x + 12 = -5
Subtract 12 from both sides to get x by itself.

12 - 12 = 0
-5 - 12 = -17 (when subtracting from a negative, you are basically adding positive numbers with a negative sign).
You are left with:

x = -17

I hope this helps!

For the function g(x)=3x^2-3x-9 what is the value of g(4)
Annette [7]
G(4) = 3x^2 - 3x - 9

Since the g(4) would be g(x) if you didn't know the number. So, substitute all of the x's for 4.

g(4) = 3(4)^2 - 3(4) - 9

g(4) = 3(16) - 12 - 9

g(4) = 48 - 3

g(4) = 45

I hope this helps you!

What system shows the correct numbers to multiply by the coefficients in order to eliminate y from the first two
Ann [662]

Answer:

3 (5x+2y = 0)

2 (2x – 3y = -19)

Step-by-step explanation:

5x+2y=0 (1)

2x-3y=-19 (2)

To eliminate y from the first two equation when applying the linear combination method

We will multiply y Equation (1) and (2) with 3 and 2 respectively so that the coefficients of y in the two equations +6 and -6 respectively

3(5x+2y=0)

2(2x-3y=-19)

We have,

15x+6y=0 (3)

4x-6y= -38 (4)

Add Equation (3) and (4)

19x=-38

x= -2

Substitute x= -2 into (1)

5x+2y=0

5(-2)+2y=0

-10+2y=0

-10= -2y

y=-10/-2

=5

y=5, x=-2

If the 1st and 10th terms of geometric sequence are 4 and 100, find the nth term of the sequence
Masja [62]

a = 4 first term, r = ?, T10 = 100.

Tn = ar^n - 1 formula for g.p

T10 = 4r^ 10 - 1

100 = 4r^9

Divide both side by 4

100/4 = 4/4r^9

25 = r^9 take the 9th root of both side

9√25 = 9√r^9

r = 9√25

To find the nth term

Since Tn = ar^n - 1
