2/3y-2/5=5

We move all terms to the left:

2/3y-2/5-(5)=0

Domain of the equation: 3y!=0

y!=0/3

y!=0

y∈R

determiningTheFunctionDomain

2/3y-5-2/5=0

We calculate fractions

There is no solution for this equation

on the coordinate grid, the graph of y=³√-x-1 is shown. it is a reflection and translation of y= ³√x. what is the range of the g
Leni [432]
The range is the set of possible images, i.e. "y".

So you can discard options "a" and "c".

2 is a possible image, and all the real numbes are.

Then the answer is "d. y | y is a real number"

Send help please I am confused aaa According to the distributive law, what operation goes in the blank? -(8 - 7) = - 8 __ 7
Rina8888 [55]

Two negative signs together change the sign to a positive sign.

Using the distributive property with the 7 you would have -(-7), the two negatives would make it +7

So you end up with -8 + 7

A jogger ran 3 miles due east of his house. then he ran 5 miles at a heading of 30o east of north (or 30o ne). how far is he fro
Natasha_Volkova [10]

Magnitude of the net displacement: 7.0 miles

Step-by-step explanation:

In order to find the total displacement of the man, we have to resolve each displacement along the x- and y- direction.

Taking x as positive x direction and y as positive north direction:

- The first motion is 3 miles due east, so

A_x = 3 mi\\A_y = 0

- The second motion is 5 miles at 30^{\circ} east of north, so:

B_x = 5 sin 30^{\circ}=2.5 mi\\B_y = 5 cos 30^{\circ}=4.3 mi

So the components of the net displacement are

R_x = A_x + B_x = 3 + 2.5 = 5.5 mi\\R_y = A_y+B_y = 0 + 4.3 = 4.3 mi

And so the magnitude of the net displacement is

d=\sqrt{R_x^2+R_y^2}=\sqrt{5.5^2+4.3^2}=7.0 mi

So, he is 7.0 miles far from the house.

Help me please if you can
tekilochka [14]

Answer:

<D=<J

Step-by-step explanation:

The first answer is the only correct statement. In geometry, congruent angles are shown through the number of arcs on the vertex of an angle. For example, if two different angles both had three arcs on the vertex, then those two angles are congruent. In this figure, both <D and <J have 4 arcs, which means they are congruent. Additionally, both angles are opposite of a line that measures 25 inches. If two angles are opposite of congruent lines, then the angles are also congruent.
