Answer: You need to grap a square where each side has 10 units in the grid.
Step-by-step explanation:
We know that each square has a side lenght of 0.1mm
Each unit in the grid represents 0.01mm
Then 10 units in the grid will represent 10*0.01 mm = 0.1mm.
Then the square face will be writen a square with a lenght of 10 units.
Answer: x^2 - 6x - 18
Step-by-step explanation:
(f-g)(x)=f(x)-g(x)=(x^2 - 5x - 24)-(x-8) = x^2 - 5x - 24 - x + 8 = x^2 - 6x - 18
The answer is C: multiply by 2
Answer:
12 cm
Step-by-step explanation:
This is a proportionality/similarity problem.
10 cm turned to 4 cm. So by how much has it decreased? In other words, <em>10 multiplied by </em><em>WHAT</em><em> is 4?</em>
0.4 is also known as the scale factor from the large diagram to the small diagram.
So how much would 30 cm become?<em> It would be 30 multiplied by the scale factor, which is </em><em>0.4</em><em>.</em>
<u>Hence, the length of the reduced diagram would be </u><u>12 cm</u><u>.</u>
So to solve this question, your goal is to find out how the way it is solved is not correct.
Your answer would be: On the third line, the student adds the 8 to both sides instead of subtracting. The way the initial equation is given is
y-(-8)=-6(x-2). After distributing the six, the student should make the 8 positive because subtracting a negative makes a positive. After solving, the equation should look like: y(+8)=-6x+12, so you would subtract the 8 from both sides instead of adding it, and solve from there.
