2y=-24-8x 6x+18=54 solve system

Mathematics

6 0

Answer:

Step-by-step explanation:

6x+18 = 54

2y = 24-8x

(I'm solving by substitution)

6x=54-18

6x=36

x=6

Then plug into the other equation

2y = -24 - 8x

2y = -24 - 8(6)

2y = -24 - 48

2y= -72

y=-36

Let A={1'3'5'6}<br> B={0'7}<br> check whether A and B are disjoint sets

Setler79 [48]

Given:

The sets are $A=\{1,3,5,6\}$ and $B=\{0,7\}$ .

To find:

Whether A and B are disjoint sets or not.

Solution:

Two sets are called disjoint sets if there are no common elements between them.

We have,

$A=\{1,3,5,6\}$

$B=\{0,7\}$

Clearly, there is not common elements between the set A and set B.

Therefore, the sets A and B are disjoint sets.

Jaime en un joven que vive en puyo con su padre. A jaime le gusta cosechar chonta con su padre los sabados en la mañana jaime ha

xenn [34]

Answer:

$\large \boxed{\text{23 s}}$

Step-by-step explanation:

Jaime is at point A and wants to get across the river to Point B.

They must head upstream towards Point C.

1. Calculate the net speed across the river.

∆ABC is a right triangle, so

$\begin{array}{rcl}AB^{2} + BC^{2} & = & AC^{2} \\AB^{2} +10^{2} & = & 12^{2} \\AB^{2}+100& = & 144 \\AB^{2}& = & 44\\AB & = & \sqrt{44}\\& = & 2\sqrt{11}\\& \approx &\textbf{6.633 m/s}\\\end{array}$

2. Calculate the time to cross the river

$\text{Time} = \text{150 m} \times \dfrac{\text{1 s}}{\text{6.633 m}} \approx \textbf{23 s}\\\\\text{It will take $\large \boxed{\textbf{23 s}}$ to cross the river.}$
