Answer:

B. y=1/2+2

Step-by-step explanation:

since parallel lines always have the same slope, the only two possible answers could be B and C. in order to find if one of those goes through point (-2,1), we have to set up an equation to find the base:

1=1/2(-2)+b

1=-1+b

2=b

We can plug in the base with the slope for the equation and the new equation would be y=1/2x+2

If 8 identical blackboards are to be divided among 4 schools, how many divisions are possible? how many if each school must rece

DaniilM [7]

Alright, so we'd use the combinations with repetition formula, so we choose from 4 schools to distribute to and distribute 8 blackboards. It's then

( 8+4-1)!/8!(4-1)!=11!/(3!*8!)=165

For at least one blackboard, we first distribute 1 to each school and then have 4 blackboards left, getting (4+4-1)!/4!(4-1)!=7!/(4!*3!)=35

The position function for the movement of a particle is given by s=(t^3+1)^2 where s is measure in feet and t is measured in sec

Ray Of Light [21]

Answer:

The position of particle at 1 second is 4 feet.

Step-by-step explanation:

We are given the following in the question:

$s(t)=(t^3+1)^2$

where s is a position function and measure in feet and t is measured in seconds.

We have to evaluate the position at 1 second.

Putting t = 1 in the position function, we get.

$s(1)=((1)^3+1)^2\\s(1) = 4$

Thus, the position of particle at 1 second is 4 feet.

Solve the system of equations by substitution.

n200080 [17]

Answer:

x = -8

y = -6

Step-by-step explanation:

y = -2x - 22

y = x + 2

x + 2 = -2x - 22

x + 2x = -22 - 2

3x = -24

x = -24 : 3

x= -8

y = -8 + 2

y = -6
