Answer:

step by step explanation

anyanavicka [17]2 years ago
5 0

Step-by-step explanation:

x=2 y=0

x= -2 y= -4

y=mx+b

b= 2

-4 = -2m +2

-2m= -6

m=3

y= 3x +2

.......

x=0 y=4

x=2 y= 2

y=mx+b

b=4

2=2m+4

2m= -2

m= -1

y = -x +4

Carlos is a member of a gym. He pays a monthly fee plus a per- visit fee. The equation y = 3x + 10 represents the monthly amount
IrinaK [193]

Answer:

25 times

Step-by-step explanation:

To find how many times he visited, plug in 85 as y and solve for x:

y = 3x + 10

85 = 3x + 10

75 = 3x

25 = x

So, Carlos visited the gym 25 times

Find a vector parametrization for the line with the given description. Perpendicular to the yz-plane, passes through (0, 0, 8)
Brilliant_brown [7]

Answer:

\left\{\begin{array}{l}x=t\\ \\y=0\\ \\z=8\end{array}\right.

or

\overrightarrow{(t,0,8)}

Step-by-step explanation:

yz-plane has the equation x=a, where a is a real constant. The normal vector of this plane (vector perpendicular to the plane) is

\overrightarrow {n}=(1,0,0)

If the line is perpendicular to this plane, then it is parallel to the normal vector, so the equation of this line is

\dfrac{x-x_0}{1}=\dfrac{y-y_0}{0}=\dfrac{z-z_0}{0},

where (x_0,y_0,z_0) are coordinates of the point the line is passing through.

In your case, the line is passing through the point (0,0,8), so the canonical equation of the line is

\dfrac{x-0}{1}=\dfrac{y-0}{0}=\dfrac{z-8}{0}

Write a vector parametrization for this line

\left\{\begin{array}{l}\dfrac{x-0}{1}=t\\ \\\dfrac{y-0}{0}=t\\ \\\dfrac{z-8}{0}=t\end{array}\right.\Rightarrow \left\{\begin{array}{l}x=t\\ \\y=0\\ \\z=8\end{array}\right.
