What’s the answer for -3(r-4)_>0

Mathematics
1 answer:
Zigmanuir [339]3 years ago
8 0

Answer:

r<4

Step-by-step explanation:

-3(r-4)>0 step 1: distribute the -3

-3r+12>0  explain: -3 times r =-3r, -3 times -4 = 12

next, isolate the -3r by putting 12 on the other side

-3r+12>0    subtract 12 from both sides

-3r>-12    now, divide both sides by -3    (you have to flip the > because you are dividing by a negative) -12 divided by -3 is 4

so you should end up with r<4

The equation x^2/121 + y^2/1. what points are the vertices of the eclipse
Alla [95]
Answer:

(-11,0) and (11,0).

Step-by-step explanation:

The given ellipse has the equation:

\frac{x^2}{121}+\frac{y^2}{1}=1

This can be rewritten as

\frac{x^2}{11^2}+\frac{y^2}{1^2}=1

We compare this to the general equation of the ellipse:

\frac{x^2}{a^2}+\frac{y^2}{b^2}=1

We have a=11 and b=1

The vertices of this ellipse are at (-a,0) and (+a,0).

Therefore the vertices of this ellipse are at (-11,0) and (11,0).

The correct choice is A.

What is the value of x and y?
crimeas [40]

Answer:

C. x = 8 , y = 40

Step-by-step explanation:

since this is an Isosceles triangle 5x = 40° and x = 8

The sum of interior angles in a triangle is equal to 180°

40° + 5x + 2y + 20 = 180° add like terms

5x + 2y = 120

40 + 2y = 120 ➡ 2y = 80 and y = 40
