It’s obtuse

Explanation:
Assign the sides by length with c being longest
If (a^2)+(b^2)>(c^2) it’s acute

If (a^2)+(b^2)=(c^2) it’s right

And if (a^2)+(b^2)<(c^2) it’s obtuse

Since (3^2)+(9^2)=9+81=90
And 10^2=100 we know that (a^2)+(b^2)<(c^2) so it’s obtuse

If y varies directly with x and Y equals 12 when X equals four what is the constant of proportionality
wariber [46]

Answer:

3

Step-by-step explanation:

If  y varies directly with x, we have:

y \propto x\\$Introducing the constant of proportionality, k\\y=kx

When y=12, x=4

Substituting these values into the equation

12=4k

k=12/4

k=3

The constant of proportionality is 3.

The given line passes through the points (-2,-4) and (2,2) What is the equation, in point-slope form, of the line that is parall
Morgarella [4.7K]

Answer:

(y-1)=\frac{3}{2}(x+3)


Step-by-step explanation:

The point slope form of a line is (y-y_1)=m(x-x_1) where x_1=-3\\y_1=1. We write  

(y-1)=m(x--3)\\(y-1)=m(x+3)


Since the line is parallel to the line shown it will have the same slope. To find m, count the slope from each marked point on the graph. Count the rise then the run and create a fraction rise/run. The slope is 6/4 which simplifies to 3/2. Now substitute it for m.

(y-1)=\frac{3}{2}(x+3)

G(x) = 2x + 1<br> 2. g(10) =
nignag [31]
G(10) = 21
You plug in 10 and multiply it with 2, then add 1, which you’ll get 21.

What is the simplified form of the equation fraction 4 over 5 n minus fraction 1 over 5 equals fraction 2 over 5 n?
Gennadij [26K]
4/5n – 1/5 = 2/5n
Add 1/5 to both sides
4/5n = 2/5n + 1/5
Subtract 2/5n from both sides
2/5n = 1/5
Divide both sides by 2/5

n = 1/2
