Answer:
x - 2 => x = 2
x² + 3ax - 2a
=> 2² + 3 × a × 2 - 2 × a
=> 4 + 6a - 2a
=> 4 + 4a
=> 4 ( 1 + a )
★ 1 + a = 0
a = -1
Answer:
D. The scuba diver was 35 meters below the surface of water at the start of the ascent.
Step-by-step explanation:
The y-intercept of the graph representing the scuba's driver ascent to the surface is -35.
This represents the starting level below the surface of the water.
✅-35, means that the driver was 35 meters below the surface of water at the start of the scuba's ascent to the surface.
Answer:
slope = 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
3y = 6x - 1 ( divide all terms by 3 )
y = 2x -
← in slope- intercept form
with slope m = 2
Answer:
Divide 16 1/2 and 5.
16 1/2 in decimal form is 16.5 so divide it by 5 and you get 3.3 or 3 and 3/10 in fraction form.
Her average work day was 3.3 hours.
Answer:
0.00000002119188
Step-by-step explanation:
If you enter this number into a spreadsheet (with a single E), you can set the display format to show you the value in standard form. The exponent (E) of -8 indicates the most-significant digit (2) is in the 8th place to the right of the decimal point:
= 2.119188×10^-8
= 0.00000002119188
