Answer:
C. { -9, 9}
Step-by-step explanation:
An absolute value equation has 2 solutions, a positive and a negative
|x|= 9
x= +9 and x = -9
Answer:
B
Step-by-step explanation:
Because the slope is a positive slope (goes through the positive quandrants on the graph), we can eliminate answer choices c. Now, if we solve a, b, and d and we can see if the slope + y-intercept matches the graph.
For A.) (solve for y to get a y=mx + b equation)
3x-2y=4
-2y= -3x + 4
<u>y= 3/2 -2</u>
For B.)
3x-2y= -4
-2y= -4-3x
<u>y= 3/2 + 2</u>
For D.)
2x+3y= 4
3y= 4-2x
<u>y= -2/3x + 4/3</u>
Now, if we look at D, the slope is negative so it cannot be D. That leaves us with A and B. The b in the y=mx + b equation stands for the y-intercept, so we can see that the y-intercept is 2. So, since the graph intersects the y-axis at (0,2), the answer is B! y=3/2 + 2 has a positive slope and 2 for the y-intercept!
Its B, because (x-7)(x+1)=x^2-6x-7.
Answer:
Step-by-step explanation:
Given:
Width of average grain of salt is, 
Width of Rhinovirus is, 
Now, expressing each width in scientific notation form, we get:
Now, in order to get how many times 'W' is wider than 'w', we divide the two widths. This gives,
Therefore, the grain of salt is wider than Rhinovirus.
