8x - 10 = 86 {combined like terms}

8x = 96 {added 10 to both sides}

x = 12 {divided both sides by 8}

3x - 5 = 31 {substituted 12, in for x, into 3x - 5}


width = 12 in.

length = 31 in.

A system of equations is shown below.
prisoha [69]

Given:

The system of equations is

y=1.5x-3

y=1.5x+4

To find:

The true statement about the given system of equations.

Solution:

The slope intercept form of a line is

y=mx+b

Where, m is the slope and b is the y-intercept.

We have,

y=1.5x-3

y=1.5x+4

On comparing these two lines with slope intercept form, we get

m_1=1.5,b_1=-3

m_2=1.5,b_2=4

Since the slopes of the lines are equal but the y-intercepts are different, therefore, the two lines are parallel and the system has no solution.

Therefore, the correct option is A.

How many ways can a dance instructor send 4 of her 11 students to a summer dance program?
Sedaia [141]

Answer:

d) 330

Step-by-step explanation:

The number of ways can a dance instructor send 4 of her 11 students to summer dance program is  C(11 , 4)

That is 11_{C_{4} } ways

by using formula n_{C_{r} } = \frac{n!}{(n-r)!r!}

now simplification

11_{C_{4} } = \frac{11!}{(11-4)!4!}

      = \frac{11X10X9X8X7!}{(7!)4X3X2X1}

after cancelling 7! and on simplification

   = \frac{11X10X9X8}{4X3X2X1}

after cancellation we get 330 ways

The number of ways can a dance instructor send 4 of her 11 students to summer dance program is 330
