6 0

$1.\\\underline{y}+\underline{1.2y}+\underline{1.2z}\to\boxed{y;\ 1.2y;\ 1.2z\to\boxed{D}}$

$2.\\2+17x-5x+9=(17x-5x)+(2+9)=\boxed{12x+11\to\boxed{B}}$

$3.\\3(5y+6)-4=(3)(5y)+(3)(6)-4=15x+18-4=\boxed{15y+14\to\boxed{C}}$

$4.\\81-27p=27\cdot3-27\cdot p=\boxed{27(3-p)\to\boxed{B}}\\but\\81-27p=9\cdot9-9\cdot3p=\boxed{9(9-3p)\to\boxed{A}}$

Step-by-step explanation:

So in the equation given, y = 2x - 3

you substitute x for whats given in the table in the x column.

Example

In the graph the first number under the x colum is -1.

y = 2x - 3 in the equation you take out x and put -1.

So now the equation becomes y = 2 × -1 - 3.

Using bedmas to solve the question you should get -5

Which now means y = -5

To plot the point now x would be -1 and y would be -5 (-1, -5)

Same thing for the second number in the x Column.

y = 2 × 1 - 3 which equals -1

To plot it

x = 1 y = -1. (1, -1)

And for the last number 3.

Agai. You substitute x for 3 which makes the equation y = 2 × 3 - 3

this gives you 3 and to plot it

x would be 3 and y would be 3

cause tsunami - If there is a disturbance in the earth's surface near sea's, etc there is chance of tsunami.

Triangle XYZ is translated 4 units up and 3 units left to yield ΔXYZ. What is the distance between any two corresponding points

Mashcka [7]

<h3>Answer:</h3>

5 units

<h3>Step-by-step explanation:</h3>

A point 4 up and 3 over from its original location has moved a distance that can be found using the Pythagorean theorem.

... d² = 4² +3² = 16 +9 = 25

... d = √25 = 5 . . . . units
