Answer:
The scale factor is 0.5
Step-by-step explanation:
Figure A is 4 blocks wide and 4 blocks tall, Figure B is 2 blocks tall and 2 blocks wide, to get Figure B from Figure A you would need to scale it down by half (0.5)
There are 3 lines of reflectional symmetry in an equilateral triangle
Answer:
y = x^2 + 6
Step-by-step explanation:
Answer:
2x² + 6x - 4
Step-by-step explanation:
f(x) - g(x)
= 3x² + x - 3 - (x² - 5x + 1) ← distribute
= 3x² + x - 3 - x² + 5x - 1 ← collect like terms
= 2x² + 6x - 4
Answer:
1st option
Step-by-step explanation:
7x + 7 and 112 are vertically opposite angles and are congruent , then
7x + 7 = 112 ( subtract 7 from both sides )
7x = 105 ( divide both sides by 7 )
x = 15
4y and 112 are adjacent angles and sum to 180° , that is
4y + 112 = 180 ( subtract 112 from both sides )
4y = 68 ( divide both sides by 4 )
y = 17
