Solve system using eliminations<br> 2x+4y=22<br> 2x-2y=-8

KATRIN_1 [288]

$2x+4y=22 \\
2x-2y=-8 \ \ \ |\times (-1) \\ \\
2x+4y=22 \\
\underline{-2x+2y=8} \\
2x-2x+4y+2y=22+8 \\
6y=30 \ \ \ |\div 6 \\
y=5 \\ \\
2x-2y=-8 \\
2x-2 \times 5=-8 \\
2x-10=-8 \ \ \ |+10 \\
2x=2 \ \ \ |\div 2 \\
x=1 \\ \\
\boxed{(x,y)=(1,5)}$

What is the slope between (14,-8) and (7,-6)

djyliett [7]

Answer:

$- \frac{2}{7}$

Step-by-step explanation:

Slope formula:

$\boxed{ slope = \frac{y _{1} - y_2 }{x_1 - x_2} }$

where (x₁, y₁) is the first coordinate and (x₂, y₂) is the second coordinate

Slope

$= \frac{ - 8 - ( - 6)}{14 - 7}$

$= \frac{ - 8 + 6}{7}$

$= - \frac{2}{7}$

Write an equation to represent the number puzzle. Use x as the

k0ka [10]

<h3>The equation is:</h3><h3> $x^2 - 7x + 12 = 0$ </h3><h3>The number is 3 or 4</h3><h3><em><u>Solution:</u></em></h3>

Given that,

7 added to the square of a number is equal to 7 times the number, minus 5

Let "x" be the unknown number

From given,

7 added to square of x = 7 times the x minus, 5

$7 + x^2 = 7x - 5$

Solve the above equation

$x^2 -7x +7+5 = 0\\\\x^2 - 7x + 12 = 0$

Split the middle term

$x^2 -3x - 4x + 12 = 0\\\\Group\ the\ expressions\\\\(x^2-3x) -(4x - 12) = 0\\\\Take\ the\ common\ factor\ out\\\\x(x -3) -4(x -3) = 0\\\\(x-3)(x-4) = 0$

We have two solutions

x - 3 = 0

x = 3

And

x - 4 = 0

x = 4

Thus number is 3 or 4
