NO LINKS Write an inequality to represent the phrase: The sum of a number and seven less than a number
german

Answer:

The sum of a number, which I have named 'n', and 7 can be written as the expression:

n+7

remember the word 'is' in a written problem indicates where you'll most likely use an =,≥,≤ sign. Since they say that it is 'no more than' we know that n+7 is less than or equal to the given number, so we use '≤'.

n+7≤ 1

Find a vector equation and parametric equations for the line through the point (1,0,6) and perpendicular to the plane x+3y+z=5.
tester [92]

The normal vector to the plane <em>x</em> + 3<em>y</em> + <em>z</em> = 5 is <em>n</em> = (1, 3, 1). The line we want is parallel to this normal vector.

Scale this normal vector by any real number <em>t</em> to get the equation of the line through the point (1, 3, 1) and the origin, then translate it by the vector (1, 0, 6) to get the equation of the line we want:

(1, 0, 6) + (1, 3, 1)<em>t</em> = (1 + <em>t</em>, 3<em>t</em>, 6 + <em>t</em>)

This is the vector equation; getting the parametric form is just a matter of delineating

<em>x</em>(<em>t</em>) = 1 + <em>t</em>

<em>y</em>(<em>t</em>) = 3<em>t</em>

<em>z</em>(<em>t</em>) = 6 + <em>t</em>

Solve the system of equations below.
trapecia [35]

Answer:

A) x + y = 8

B) 3x + 2y = 21

We multiply A) by -2

A) -2x -2y  = -16 Then we add this to

B) 3x + 2y = 21

x = 5

y = 3

A snail travels at a rate of 2.35 feet per minute. Write a rule to describe the function. How far will the snail travel in 5 min
PolarNik [594]

distance = speed x time

distance = 2.35 x time

distance = 2.35 x 5

distance = 11.75 feet in 5 minutes
