HELP ME PLZ!!!!!!!! Find the solution of this system of equations.

1 answer:

7 0

Set equal to each other since both equal 90

5x-6y=-10x-6y
add 6y to both sides
5x=-10x
x=0

5(0)-6y=-90
-6y=90
divide by -6
y=-15

(x,y)
(0,-15)

Answer:

0.45

Step-by-step explanation:

For a uniform distribution,

$f(x) = \frac{1}{b - a} \\$

where a is the minimum and b the maximum\\

cumulatively, $F(x) = \frac{x - a}{b -a}$

$F(x >= 24.9) = \frac{24.9 - 24}{26 - 24} = \frac{0.9}{2} = 0.45$

Find a value for y for which the expression (1-y)(3-y)(6-y) has each given value

erik [133]

$\\ \tt\Rrightarrow (1-y)(3-y)(6-y)=-70$

$\\ \tt\Rrightarrow -y(1+1)(3+1)(6+1)=-70$

$\\ \tt\Rrightarrow y(2)(4)(7)=70$

$\\ \tt\Rrightarrow y(56)=70$

$\\ \tt\Rrightarrow y=\dfrac{70}{56}$

$\\ \tt\Rrightarrow y=\dfrac{5}{4}$

$\\ \tt\Rrightarrow (1-y)(3-y)(6-y)=120$

$\\ \tt\Rrightarrow -y(1+1)(3+1)(6+1)=120$

$\\ \tt\Rrightarrow -y(2)(4)(7)=120$

$\\ \tt\Rrightarrow 56y=-120$

$\\ \tt\Rrightarrow y=\dfrac{-120}{56}$

$\\ \tt\Rrightarrow y=\dfrac{-15}{7}$
