Solve each system of equation for 3y+x=3 and -2y+5x=15

madam [21]

Answer:

x = 3 and y = 0

Step-by-step explanation:

3y+x=3

-2y+5x=15

Isolate y in 3y + x = 3 :

$y=$ $\frac{3-x}{3}$

Substitute $y = \frac{3-x}{3}$ in -2y + 5x = 15 :

$-2 * \frac{3-x}{3} + 5x = 15$

Simplify the equation :

$\frac{-6+17x}{3} =15$

Isolate x in $\frac{-6 + 17x}{3} = 15$ :

Proving x = 3

Isolate y in $y = \frac{3-3}{3}$ :

Proving y = 0

Your solved system of equations are x being 3, and y being 0.

vampirchik [111]

Answer: A = 1,625.82 m³

Step-by-step explanation:

The volume of a rectangular prism can be found with;

A = L * W * H

A = (15.8m) * (24.5m) * (4.2m)

A = 1,625.82 m³

FOR AN EXAM DUE TODAY!!! Simplify the polynomial. 3x – 2x2 + 4 – x2 + x + -

Mashutka [201]

Answer:

${ \tt{ \blue{ - {3x}^{2} + 4x + 4 }}}$

Step-by-step explanation:

${ \tt{3x - {2x}^{2} + 4 - {x}^{2} + x }} \\$

» Collect second degree terms (x² coefficients) together and first degree terms (x coefficients) and constants

$= { \tt{( - 2 - 1) {x}^{2} + (3 + 1)x + 4 }} \\ = { \boxed{ \tt{ \: - {3x}^{2} + 4x + 4}}}$
