8·(5+(18-7))÷4
Remember PEMDAS, Parenthesis, Exponents, Multiply, Divide, Add, Subtract 
First Step: 18-7=11
New equation would be: 8·(5+11)÷4
Second Step: 11+5=16
New equation would be: 8·16÷4
Third Step: 8·16=128
New equation would be: 128÷4
Fourth Step: 128÷4=32
So the answer would be 32
Hope this helps :)

The answer is 32. This is because, first according to The Order of Operations, we do parentheses first (or other grouping symbols). So now the equation looks like this: 8(5 + 11) divided by 4. Next, we add 5 +11, which is 16, so 8(16) = 128, and 128 divided by 4 is 32. I hope this helps! If you need helps on the Order of Operation, please ask! :D

ONE QUESTION ONLY!!!

Let first number = X and 2nd number = Y

Equation 1: 5X + 8Y = -13

Equation 2: 5X + 10Y = -15

Multiply equation 1 by -1 to get: -5X + -8Y = 13

Now add the 2 equations together:
-5X + 5X = 0

-8Y + 10Y = 2Y

13 + -15 = -2

The total of the 2 equations is 2Y = -2

divide both sides by 2 to solve for Y
Y = -2 / 2
Y = -1
 Now we know the 2nd number is -1, so replace Y in the 1st equation and solve for X

5X +8(-1) = -13

5x + -8 = -13

Add 8 to both sides:
5x = -5

Divide both sides by 5 to get x

X = -5 / 5
X = -1

Both numbers are -1

To check replace X and Y with -1 and solve:

1st equation: 5(-1) +8(-1) = -5 + -8 = -13  TRUE

2nd equation: 5(-1) +10(-1) = -5 + -10 = -15 TRUE

Both numbers are -1

Need help with translation
sergij07 [2.7K]

Answer:

The translation rule will be: (x, y) → (x+3, y+9)

Step-by-step explanation:

As X'Y' is a translation of XY.

As the location of the vertix X is (-4, -9) and the coordinates of vertex Y is (-5, -5).

As X'Y'  be the vertices of the translated figure.

So, if we translate the segment XY +3 units in the x-direction and +9 units in the y-direction, i.e.

(x, y) → (x+3, y+9) = (-4+3, -9+9) = (-1, 0) = X'

and

(x, y) → (x+3, y+9) = (-5+3, -5+9) = (-2, 4) = Y'

so, the image X'Y' will have the X' vertice at the location (-1, 0) and Y' vertice at the location (-2, 4).

Therefore, the translation rule will be: (x, y) → (x+3, y+9)
