Answer: y=5x+7

Step-by-step explanation:

If you draw a graph or use a graphing calculator the points and then connect them you will see that the y-intercept is 7 and the slope is 5/1. Slope intercpt form is y=mx+b. So the equation is y=5x+7.

Answer:

let (x1,y1)=(1, 2)

and(x2,y2)=(3,-8)

Step-by-step explanation:

we have

y-y1=(y2-y1)(x-x1)/(x2-x1)

y-2=(-8-2)(x-1)/(3-1)

y-2=-10(x-1)/2

y-2=-5(x-1)

y-2=-5x--5

y+5x=5+2

5x+y=7 is the required equation.

One angle of a triangle measures 102°. The other two angles are congruent.

Karolina [17]

Answer:

if i am rightthe two other angles arre 39

Step-by-step explanation:

if a triganle is 180 degrees and you have already one angle then all you do is subtract 180 and 102

180-102= 78

then since you need the other two angles all you do is divide it by 2

so 78/2= 39 so the two missing anlges are 39

Answer:

p(-5/3) ≠ 0 So, (3 x +5) is NOT A FACTOR of p(x)

Step-by-step explanation:

Here, the given function is $p(x)=3x^5+2x^2 - 5$

Now, the given root of the function is ( 3x +5)

Now, if ( 3 x + 5) = 0,

we get x = - 5/3

So, the zero of the given polynomial is x = -5/3

Then, x = -5/3, p(x) =0 ⇒ ( 3 x + 5) is a FACTOR of p(x)

Now, let us find the value of function at x = -5/3

Substitute x = -5/3 in the given function p(x), we get:

$p(x)=3x^5+2x^2 - 5 \implies p(\frac{-5}{3}) = 3(\frac{-5}{3})^5 + 2(\frac{-5}{3})^2 - 5\\= 3(\frac{-3,125}{243}) + 2(\frac{25}{9}) - 5\\= (\frac{-3,125}{81}) + (\frac{50}{9}) - 5\\= -38.580 + 5.56 - 5 = -38.02\\\implies p(\frac{-5}{3}) = -38.02$

Now, as p(-5/3) ≠ 0 So, (3x +5) is NOT A FACTOR of p(x)

Chris types at an average speed of 35 words per minute. He has already typed 1,500 words of his final paper. The paper has to be

MrRa [10]

Answer:

1750 + 35x ≥ 3250

Step-by-step explanation:

Average speed = 35 words

He has already typed 1500 words on his final paper

The paper must be more than 3250 words.

To find at least how many more words he has to type, we will subtract 1500 from 3250

3250 - 1500 = 1750 words

The equation will be 35x ≥ 1750

x is the number of minutes

The equation could be

1750 + 35x ≥ 3250
