Multiply 
by 80 and you will get how many boys play video games daily.
44 is the number of boys who play video games daily.
Answer:
It decreased
Step-by-step explanation:
It decreased. Assuming that the temperature is 100 and it is now reduced by 60% then the temperature will be at 40 and if it increased by 80% then the final temp is 72. So it is 48% of the original temp.
X^3 + 10x^2 + 24x
divide by x
x(x^2 + 10x + 24)
factor it
x(x+4)(x + 6)
now solve for x
the answer is -6,0,-4
(-79.54) / (-9.7) = <span>8.2
Steps:
</span>
<span><span>Conversion: 79.54 = <span>7954/100</span> = <span>3977/50
</span></span><span>Unary minus: -79.54 = -<span>3977/50</span></span><span>
Conversion: 9.7 = <span>97/10</span></span><span>
Unary minus: -9.7 = -<span>97/10
</span></span><span>Divide: -<span>3977/50</span> / (-<span>9710</span>) = <span>-397750</span> · <span>10-97</span> = <span>-3977 · (-10)50 · 97</span> = <span>397704850</span> = <span>415
</span>To divide one fraction by another, invert (turn upside-down) the second fraction, then multiply.

Answer: Last option.
Step-by-step explanation:
The equation of the line in slope-intercept form is:
Where m is the slope and b the intersection with the y-axis.
You can observe in the graph that the line passes through the origin, then:
Choose two points of the line and calculate the slope with:
Points: (2,3) and (-2,-3)
Substitute values, then the slope is:
Substituting "m" and "b" into , you get that the equation is:
This can be written as:
