Answer:

8 miles

Step-by-step explanation:

Britney went from -4 to 6, or 10 miles, and then from 10 to -14, or 24 miles. Add these together and Britney traveled 34 miles

Alice went straight from the library to school, so we need to find the hypotenuse of the triangle. Use the Pythagorean theorem (a^2 + b^2 = c^2) and substitute 10 for a and 24 for b to get 100 + 576 = c^2 or 676 = c^2

Take the square root of 676 to get 26 for Alice's distance.

34-26=8

Answer:

9x + 7

Step-by-step explanation:

Given

6x + 5y + 3x + 7 - 5y ← collect like terms

= (6x + 3x ) + (5y - 5y ) + 7

= 9x + 0 + 7

= 9x + 7

Use each picture or description of a triangle, write and solve an equation in order to find the number of degrees in each angle

TiliK225 [7]

4x + 7x - 2 + 5x - 10 = 180

16x - 12 = 180

16x = 192

x = 12

m<A= 4x = 4(12) = 48

m<B = 7x - 2 = 7(12) - 2 = 84 - 2 = 82

m<C = 5x - 10 = 5(12) - 10 = 60 - 10 = 50

solve the system of equations by finding the reduced row-echelon form of the augmented matrix for the system of equations. x-2y+

Alekssandra [29.7K]

Answer:

x = -5, y = -6, z = -3

Step-by-step explanation:

Given the system of three equations:

$\left\{\begin{array}{l}x-2y+3z=-2\\6x+2y+2z=-48\\x+4y+3z=-38\end{array}\right.$

Write the augmented matrix for the system of equations

$\left(\begin{array}{ccccc}1&-2&3&|&-2\\6&2&2&|&-48\\1&4&3&|&-38\end{array}\right)$

Find the reduced row-echelon form of the augmented matrix for the system of equations:

$\left(\begin{array}{ccccc}1&-2&3&|&-2\\6&2&2&|&-48\\1&4&3&|&-38\end{array}\right)\sim \left(\begin{array}{ccccc}1&-2&3&|&-2\\0&-14&16&|&36\\0&-6&0&|&36\end{array}\right)\sim \left(\begin{array}{ccccc}1&3&-2&|&-2\\0&16&-14&|&36\\0&0&-6&|&36\end{array}\right)$
