How do I solve for a and b A(5)-b(-2)=24

Mathematics
1 answer:
fiasKO [112]4 years ago
7 0

Answer:

Step-by-step explanation:

The three methods most commonly used to solve systems of equation are substitution, elimination and augmented matrices. Substitution and elimination are simple methods that can effectively solve most systems of two equations in a few straightforward steps.Understand what multi-variable equations are. Two or more linear equations that are grouped together are called a system. That means that a system of linear equations is when two or more linear equations are being solved at the same time.[1] For example:

8x - 3y = -3

5x - 2y = -1

These are two linear equations that you must solve at the same time, meaning you must use both equations to solve both equations.

The volume of a rectangular prism is (x^3-3x^2+5x-3)/(x^3-2)
Trava [24]
<span>The volume of a rectangular prism = its base area * height

substitute:
</span>
x3 – 3x2 + 5x – 3 =<span> (x2 – 2) * h

h=</span> (x3 – 3x2 + 5x – 3)/<span>(x2 – 2)

so you can use the long division</span>

Which of these points lies on the line discribed by the equation below? y-4= -2(x-6)
Basile [38]

Answer:

C, (6,4)

Step-by-step explanation:

The points (x,y) that lie on the line must fit into the equation correctly. So, we can test out the 4 options to see whether they fit correctly into the equation.

A:

y-4

= -4 -4 = -8

-2(x-6)

= -2 (-6-6)

= 24

Since -8≠24, so A is incorrect.

B:

y -4 = -6-4 = -10

-2(x-6) = -2 (-4-6) = 20

-10≠20, so B is incorrect.

C:

y-4 = 4 -4 = 0

-2(x-6) = -2(6-6) = 0

Both sides are equal. C is correct.

But lets test D out too.

y-4 = 6-4 = 2

-2(x-6) = -2(4-6) = 4

2≠4, so D is incorrect.
