Black_prince [1.1K]

Answer: y = 31

Step-by-step explanation:

The equation of a line is y = mx+b

Plugging in the values, we get

y = 4*8 + (-1)

y = 32-1

y = 31

Help pls don’t understand this one

Scilla [17]

Answer:

EFA

Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees none of the other lines add up to 180 degrees and are also part of a vertical pair

Which exponential equation is equivalent to this logarithmic equation?

Lubov Fominskaja [6]

Answer:

$\displaystyle B)x = {5}^{9}$

Step-by-step explanation:

we are given a logarithmic equation

$\displaystyle \log_{5}(x) - \log_{5}(25) = 7$

simplify the log:

$\displaystyle \log_{5}(x) -2 = 7$

add 2 to both sides:

$\displaystyle \log_{5}(x) = 9$

remember that,

$\displaystyle \log_{a}(b) = c \iff {a}^{c} = b$

so we obtain:

$\displaystyle x = {5}^{9}$

hence,

our answer is B)

Two kids are roller skating. Amy, with a mass of 55 kg, is traveling forward at 3 m/s. Jenny, who

alekssr [168]

Answer:

They traveling at $0.37\ m/s$ in backward direction.

Step-by-step explanation:

Given mass of Ammy $m_1=55kg$

and velocity is forward at $v_1=3m/s$

Also, mass of Jenny $m_2=40kg$

Who is travelling in opposite direction $v_2=-5m/s$

Let velocity in forward direction is positive and velocity in backward direction is negative.

Also, velocity after crash is $v$

As they crashed into each other and they moved as one mass. We can apply principle of conservation of momentum.

Conservation of momentum says momentum before collision should equal to momentum after collision.

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

$(55\times3)+(40\times(-5))=(55+40)v\\\\165-200=95v\\\\-35=95v\\\\v=\frac{-35}{95}=-0.368m/s$

So, velocity after collision $v$ ≅ $-0.37m/s$ is in opposite direction. That is the direction of Jenny.
