What is the solution to the following system? 3x+3y=10 -9x-9y=-30

Degger [83]

Answer:

Infinite number of solutions.

Step-by-step explanation:

We have the equations,

1. 3x+3y=10

2. -9x-9y= -30

Now, if we multiply equation 1 with -3, we will obtain equation 2.

i.e. -3×(3x+3y)= -3×10

i.e. -9x-9= -30

So, we see that both the equations are same.

The equation 3x+3y=10 will have solution for many values of x and y.

Hence, the system will have infinite number of solutions.

How to subtract 4/5 and 3/10 in simplest form

g100num [7]

First you must find a common denominator. In this case 10 will work. You then multiply the top number by whatever you multiplied the bottom number by. This is shown below:
4/5- 3/10 = 8/10- 3/10
You can now solve this to get 5/10. This answer can then be reduced to 1/2.

1. WILL MARK BRAINLIEST!!! HELP!

MatroZZZ [7]

Answer:

$\frac{7}{x+7}$

Step-by-step explanation:

Step 1: Pull a 7 from the top

$\frac{7x + 42}{x^2 + 13x + 42}$

$\frac{7(x + 6)}{x^2 + 13x + 42}$

Step 2: Factor the bottom

$\frac{7(x + 6)}{(x + 7)(x + 6)}$

Step 3: Cancel the top (x+6) and the bottom (x+6)

$\frac{7}{x+7}$

Answer: $\frac{7}{x+7}$

10-2(2x+1)=4(x-2)solve each equation for x graph your Solution on a number line

stepladder [879]

Answer:

No solution

Step-by-step explanation:

Actually, you have only one equation here. We will solve it for x.

Performing the indicated multiplication, we obtain:

10-2(2x+1)=4(x-2) => 10 - 4x - 2 = 4x - 8, or 10 - 2 = -8. This can never be true, so this equation has no solution.

Determine the volume of the parallelepiped with one vertex at the origin and the three vertices adjacent to it at (2, â1, â1), (

valentinak56 [21]

Answer:

Step-by-step explanation:

Here is the complete question

Find the volume of the parallelepiped with one vertex at the origin and adjacent vertices at (1, 0, -3), (1, 2, 4), and (5, 1, 0).

Solution

We find the volume of the parallelepiped by making a 3 × 3 column matrix whose columns are the corresponding coordinates of the vertices of the parallelepiped.

So, (1, 0, -3), (1, 2, 4) and (5, 1, 0)

$A = \left[\begin{array}{ccc}1&1&5\\0&2&1\\-3&4&0\end{array}\right]$

The determinant of A is the volume of the parallelepiped. So,

detA = 1(2 × 0 - 4 × 1) - 1(0 × 0 - (-3) × 1) + 5(0 × 4 - (-3) × 2)

= 1(0 - 4) - 1(0 + 3) + 5(0 + 6)

= 1(-4) - 1(3) + 5(6)

= -4 - 3 + 30

= 23

So the volume of the parallelepiped is 23
