Answer:

Graph A

Step-by-step explanation:

Let

x-------> the number of cereal boxes

y------> the number of cartons of milk

we know that

$x+y=5$ -----> equation A

$y=2+2x$ -----> equation B

Solve the system of equations

Substitute equation B in equation A

$x+(2+2x)=5$

$3x=5-2$

$3x=3$

$x=1$

Find the value of y

$y=2+2x$ ------ $y=2+2(1)=4$

The solution of the system is the point $(1,4)$

therefore

The answer is the graph A

Which equation represents the line that passes through (–6, 7) and (–3, 6)?

ipn [44]

Answer:

$y = \frac{-x}{3} + 5$

Step-by-step explanation:

Given A (x₁, y₁) = ( -6, 7) and B (x₂, y₂) = (-3, 6)

Slope of line passing through points ( -6, 7) and (-3, 6) is:

m = $\frac{y_{2} -y_{1}}{x_{2} -x_{1}} =\frac{6 - 7}{-3 + 6} =\frac{-1}{3}$

Now, the equation of line in point-slope form:

(y - y₁) = m (x - x₁)

Substituting the value of m and (x₁, y₁) = ( -6, 7) in above equation,

$(y - 7) = \frac{-1}{3}(x - (-6))$

$(y - 7) = \frac{-1}{3}(x + 6)$

$3y - 21 = -x - 6$

$3y = -x - 6 + 21$

$3y = -x + 15$

$y = \frac{-x + 15}{3}$

$y = \frac{-x}{3} + 5$

Option B is the correct answer.

Batman (mass=100 kg) jumps straight down from a bridge in to a boat (mass = 580 kg) in which a criminal is fleeing. The velocity

Crank

Answer:

$v_b=11.94\ m/s$

Step-by-step explanation:

<u>Linear Momentum </u>

The momentum of a system of masses m1,m2,m3... with speeds v1,v2,v3,... is given by

$M=m_1v_1+m_2v_2+m_3v_3+...$

When some interactions take place into the system of masses with no external forces interferring, the total momentum is not changed, which means that if the new speeds are v1', v2', v3'... then:

$m_1v_1+m_2v_2+m_3v_3+...=m_1v_1'+m_2v_2'+m_3v_3'+...$

The problem relates the story of Batman (m1=100kg) who is initially assumed at rest and lands on a boat with mass m2=580 kg initially moving at 14 m/s to the positive reference. When the collision takes place, both masses join and a common speed $v_b$ is achieved by the common mass. Applying the conservation of momentum, we have

$m_1v_1+m_2v_2=(m_1+m_2)v_b$

Since $v_1=0$

$m_2v_2=(m_1+m_2)v_b$

Solving for $v_b$

$\displaystyle v_b=\frac{m_2v_2}{m_1+m_2}$

$\displaystyle v_b=\frac{(580)(14)}{100+580}$

$\boxed{v_b=11.94\ m/s}$
