Answer:

y = -3/5x - 18/5

Step-by-step explanation:

Step 1: Write out known variables

y = -3/5x + b

Step 2: Find <em>b</em>

-3 = -3/5(-1) + b

-3 = 3/5 + b

b = -18/5

Step 3: Rewrite equation

y = -3/5x - 18/5

If u = &lt;-7, 6&gt; and v = &lt;-4, 17&gt;, which vector can be added to u + 3v to get the unit vector &lt;1, 0&gt; as the resu
ivann1987 [24]

With u = <-7, 6> and v = <-4, 17>, we have

u + 3v = <-7, 6> + 3 <-4, 17> = <-7, 6> + <-12, 51> = <-19, 57>

We want to find a vector w such that

u + 3v + w = <1, 0>

Subtract u + 3v from both sides to get

w = <1, 0> - (u + 3v) = <1, 0> - <-19, 57>

w = <20, -57>

Can someone please<br> Help me?

Answer:

  see below

Step-by-step explanation:

It is easiest to compare the equations when they are written in the same form.

The first set can be written in slope-intercept form.

  y = 2x +7

  y = 2x +7 . . . . add 2x

These equations are <em>identical</em>, so have infinitely many solutions.

__

The second set can be written in standard form.

  y +4x = -5

  y +4x = -10

These equations <em>differ only in their constant</em>, so have no solutions.

__

The third set is already written in slope-intercept form. The equations have <em>different slopes</em>, so have exactly one solution.

If r/s = 22 and the value of r is 242, what is the value of s
jekas [21]

Answer:

s = 11

Step-by-step explanation:

Given

\frac{r}{s} = 22 ← substitute r = 242

\frac{242}{s} = 22 ( multiply both sides by s )

242 = 22s ( divide both sides by 22 )

11 = s

Not sure if that is the entire question, but yes, it does. Poly comes from the Greek polus or polloi meaning much or many.
