Answer:

d.

D: {-7, 0, 2, 6}

R: {-13, 0, 5, 13}

Step-by-step explanation:

Domain of a relation is the set of all input values (x-values) while the range is the set of all corresponding output values (y-values) in a given relation.

Given the relation represented by the table above,

Domain would be: {-7, 0, 2, 6}

Range: {-13, 0, 5, 13}

Solve -5x+y=1 and 9x-2y=4 using multiplication and then elimination.​
omeli [17]

Answer:

x = - 6, y = - 29

Step-by-step explanation:

Elimination:

2*(-5x + y = 1) = -10x + 2y = 2

9x - 2y = 4 = + (9x - 2y = 4) =

-x = 6

x = -6

9(-6)-2y=4

-54-2y=4

-2y=58

y=-29

8. Jasmine is playing a game where she moves a piece on a coordinate grid. Over three turns, she moves her
olga2289 [7]

Answer:

28 units.

Step-by-step explanation:

The distance between two given points (x_{1},y_{1}) and (x_{2},y_{2}) is given by the formula  

\sqrt{(x_{1} - x_{2})^{2} + (y_{1} - y_{2})^{2}}

So, the distance between points (-2,-4) and (-1,6) is

\sqrt{(-2 - (- 1))^{2} + (-4 - 6)^{2}} = \sqrt{101} = 10.05 units.

Now, the distance between points (-1,6) and (3,8) is

\sqrt{(-1 - 3)^{2} + (6 - 8)^{2}} = \sqrt{20} = 4.47 units  

Again, the distance between the points (-2,-4) and (3,8) is

\sqrt{(- 2 - 3)^{2} + (-4 - 8)^{2}} = 13 units.

Therefore,the perimeter of the triangle is (10.05 + 4.47 + 13) = 27.52 ≈ 28 units. (Approximate)

What's the simplified form of 2x + 3 = x + 5?<br> A.x-2<br> B.X-8<br> C. X + 8<br> D. 3x + 8
Mashutka [201]
It is choice d because when you add the like terms, you would add x to 2x which would be 3x and 3 plus 5 is 8, so when you plug it all in, you would get D
