You're moving the decimal 7 places to the left so the answer is 9.647 x 10^7
Answer:
y - 3 = -8(x + 7)
Step-by-step explanation:
The equation of a line with slope m through point (h, k) is ...
y -k = m(x -h)
__
The slope you want is m = -8, which is the slope of the given line.* The given point is (h, k) = (-7, 3), so the equation you're looking for is ...
y - 3 = -8(x -(-7))
The expression inside parentheses can be simplified so you have ...
y - 3 = -8(x + 7)
_____
* The given line is in "slope-intercept" form, which is y = mx + b. Matching this pattern to the given equation, you see that m=-8. Parallel lines have equal slope, so -8 is the slope of the line you're writing the equation for.
Answer:
0
Step-by-step explanation:
Substitute the value of x to the 2nd equation
3(2y-4)-6y=-12
6y-12-6y=-12
0=0
Answer: D) 20

Answer:
Kirk wrapped 7 presents with those 23.8 cm of tape.
Step-by-step explanation:
Figure out the unit rate:
10.2 cm tape
-------------------
3 presents
or
3 presents
-----------------------
10.2 cm tape
Multiplying this by 23.8 cm results in the number of presents Kirk wrapped with that much tape:
(3 presents)(23.8 cm tape
--------------------------------------- = 7 presents
10.2 cm tape
Kirk wrapped 7 presents with those 23.8 cm of tape.
