How do I solve the following system of equations? <br>-5x-3y=7<br>-3x-4y=2

garri49 [273]

Answer:

(-2, 1)

Step-by-step explanation:

Systems of equations can be solved using different methods. For this set of systems, you can multiply each equation by a factor in order to eliminate a variable and solve for the other variable:

-3(-5x - 3y = 7) or 15x + 9y = -21

5(-3x - 4y = 2) or <u>-15x -20y = 10</u>

-11y = -11

y = 1

Solve for x: -5x - 3 = 7

Add 3 to both sides: -5x -3 + 3 = 7 + 3 or -5x = 10

Solve for x: x = -2

(-2, 1)

Factor x2 + 10x – 18. prime (x + 3)(x – 6) (x – 2)(x – 9) (x – 2)(x + 5)

Marta_Voda [28]

Answer:

prime

Step-by-step explanation:

x^2 + 10x – 18

What two numbers multiply to -18 and add to +10

There are no numbers that multiply to -18 and add to 10

-1 *18 = -18 -1 +18 = 17

-2 *9 = -18 -2 +9 = 7

This cannot be factored

From first principles, find the indicated derivatives

LenaWriter [7]

By definition of the derivative,

$\displaystyle\frac{dr}{ds} = \lim_{h\to0} \frac{\left(\frac{(s + h)^3}2 + 1\right) - \left(\frac{s^3}2 + 1\right)}{h}$

$\displaystyle\frac{dr}{ds} = \lim_{h\to0} \frac{\left(\frac{s^3+3s^2h+3sh^2+h^3}2 + 1\right) - \left(\frac{s^3}2 + 1\right)}{h}$

$\displaystyle\frac{dr}{ds} = \lim_{h\to0} \frac{\frac{3s^2h+3sh^2+h^3}2}{h}$

$\displaystyle\frac{dr}{ds} = \lim_{h\to0} \frac12 \frac{3s^2h+3sh^2+h^3}{h}$

$\displaystyle\frac{dr}{ds} = \lim_{h\to0} \frac12 (3s^2+3sh+h^2)$

$\displaystyle\frac{dr}{ds} = \frac{3s^2}2$
