Answer:
Step-by-step explanation:
when a rotation of 180 ° happens, it switches the (x,y) coordinates from (x,y) to (-x,-y) .. that's alll... soo for M then, of (3,4) it switches to M ' = ( -3, -4) see?
Well, an x-coordinate is the horizontal line on a grid. The y-coordinate is the vertical line on the grid. You would have to show us the grid to answer that question.
Answer:
Infinitely many solutions.
Step-by-step explanation:
Let's begin by carrying out the indicated multiplications, which must be done before any addition or subtraction:
2(8r+5)-3=4(4r-1)+11 becomes 16r + 10 - 3 = 16r - 4 + 11.
Subtracting 16r from both sides, we get 10 - 3 = - 4 + 11, or 7 = 7
This is always true, so we can conclude that this equation has infinitely many solutions.
Answer:
-67x + 10
Step-by-step explanation:
3x + 10(1 - 7x)
(use distributive property)
3x + 10 - 70x
(simplify)
3x - 70x + 10
-67x + 10
