What is the simultanous equation of 2x+y=–5 3x+2y=–8 equation Using the Substitution method

Artyom0805 [142]

Answer: Equation $form:$ $x=-2,y=-1$

$Point$ $form:$ $(-2, -1)$

Step-by-step explanation:

$y=-\frac{3x}{2} -4$

$y=-2x-5$

Solve for the first variable in one of the equations, then substitute the result into the other equation.

Add the equations in order to solve for the first variable. Plug this value into the other equations in order to solve for the remaining variables.

$Solve$ $by$ $Substitution$ ---> $2x+y=-5 3x+2y=-8$

HURRY PLEASE!! How many sides are there in a regular polygon which has 120 degrees in each of its angeles?

N76 [4]

Number of angles = number of sides

180 - 120 = 60 (calculating the exterior angle)

360 / 60 = 6

There are 6 sides.

Hope this helps! :)

Log14/3 +log11/5-log22/15=log

Tamiku [17]

Answer:

$log7$

Step-by-step explanation:

when adding logs, apply the log rule: $\log _a\left(x\right)+\log _a\left(y\right)=\log _a\left(xy\right)$

∴ $\log\left(\frac{14}{3}\right)+\log\left(\frac{11}{5}\right)=\log\left(\frac{14}{3}\cdot \frac{11}{5}\right)$

when subtracting logs, apply the log rule: $\log _a\left(x\right)\:-\:\log _a\left(y\right)=\log _a\left(\frac{x}{y}\right)$

$\log\left(\frac{14}{3}\cdot \frac{11}{5}\right)-\log\left(\frac{22}{15}\right)=\log\left(\frac{\frac{14}{3}\cdot \frac{11}{5}}{\frac{22}{15}}\right)\\\\=\log\left(7\right)$
