Answer:
$19.8
Step-by-step explanation:
To find the answer, find the ratio.
Yes, both of your answers are correct.
Since Death Valley is below sea level, the hiker increases altitude before stopping at 0 feet.
Percent of increase is given by the formula (amount of change)/(original amount) * 100. Your work is accurate.
Hi, I actually just took the test and got 100%
Remember: When plotting the points for this equation, make sure to always first plot the ones that correspond to the first linear equation, and then plot the ones that correspond to the second linear equation.
The points on the line should be for the first linear equation, (4,0) and (8,0). I got this answer by first converting the linear equation, 2x+y=8 from standard form to slope-intercept form. To do this, I subtracted 2x from both sides of the equation. So now it reads as y=8-2x. After this step was completed, I then graphed my first linear equation.
The points on the line should be for the first linear equation, (2,4) and (6,6).
I got this answer by first converting the linear equation, -x+2y=6 into slope-intercept form. To do this, I subtracted -x from both sides of the equation. Then I had to divide the 2 into both -x and 6. So now it reads as y= 6/2-x/2. After this step was completed, I then graphed my second and final linear equation.
I hope this helps!
8 times because 8 times 8 equals 64
Y = 0 so
x^2 + 6x - 40 = 0
(x +10)(x - 4) = 0
x+10 = 0; x = -10
x - 4 = 0; x = 4
answer is C. x = -10 and x = 4
