What value of b will cause the system to have an infinite

m_a_m_a [10]

Answer:

$b=6$

Step-by-step explanation:

<u><em>The correct question is</em></u>

What value of b will cause the system to have an infinite number of solutions?

y = 6x – b

–3x + 1/2y = –3

we have

$y=6x-b$ ----->equation A

$-3x+\frac{1}{2}y=-3$ -----> equation B

we know that

If the system has infinite number of solutions then, the equation A must be equal to the equation B

isolate variable y in the equation B

$-3x+\frac{1}{2}y=-3$

Multiply by $2$ both sides

$-6x+y=-6$

$y=6x-6$ -------> new equation B

To find out the value of b, equate equation A and equation B

$6x-b=6x-6$

$b=6$

A total of 8,644 people went to the football game. Of thos the visitors side. Of the people sitting on the visitor's side filled

You divide 8644 by 8 which equals 1080.5, but since you can't have half of one person you approximate it to 1080 or 1081.

Find the values of x and y. PLEASEEE QILL GIVE BRAINLIEST

agasfer [191]

As parallel sides

$\\ \rm\longmapsto 2x+90=180$

$\\ \rm\longmapsto 2x=90$

$\\ \rm\longmapsto x=90/2=45$

Now

$\\ \rm\longmapsto 2x+3y+6y+90=360$

$\\ \rm\longmapsto 9y+180=360$

$\\ \rm\longmapsto 9y=180$

$\\ \rm\longmapsto y=20$
