3x+10y=13<br> 4(-2y+x)-9x=13

mart [117]

Answer:

$x=-9$

$y=4$

Step-by-step explanation:

$3x+10y=13$ ← Equation 1

$4(-2y+x)-9x=13\\$

By simplifying the above equation we get,

$-8y+=4x-9x=13$ (Simplifying the brackets)

$-8y-5x=13$ (By subtracting $-9x$ from $+4x$ ) ← Equation 2

Multiply Equation 1 by 5 and Equation 2 by 3 and add them together.

Equation 1 multiplied by 5 will give,

$15x+50y=65$

Equation 2 multiplied by 3 will give,

$-24y-15x=39$

Add those together,

$15x+50y-24y-15x=65+39$

$26y=104$ (After simplifying $x$ values)

Therefor $y=4$

By substituting $y=4$ to Equation 1 we get,

$3x+10*4=13$ $3x+40=13\\3x=-27\\x=-9$

Therefor we can say,

$x=-9$

$y=4$

What are the roots of the equation? x^2(5x−7)(3x+2)=0

lisov135 [29]

x = 0, x = $\frac{7}{5}$ , x = - $\frac{2}{3}$

since we have a product of factors equal to zero, equate each factor to zero and solve for x

x² = 0 ⇒ x = 0 ( multiplicity 2 )

5x - 7 = 0 ⇒ x = $\frac{7}{5}$

3x + 2 = 0 ⇒ x = - $\frac{2}{3}$

A study conducted at a certain college shows that 62% of the school's graduates find a job in their chosen field within a year a

Anna007 [38]

This can be done easily if you choose a different probability.
Find the chance that none of the 5 graduates find a job.
For one student that is 100%-62%=38%
This has to happen for all 5 students, that is P=(0,38)^5=0,008 (rounded)

This is the chance that none of the 5 students finds a job. All of the above cases at least one finds a job.

That is 1-0,008=0,992 (rounded)
