Answer:
Step-by-step explanation:
5
* 4
=5*6+5/6 * 4*2+1/2
=35/6 * 9/2
=35*9/6*2
=315/12
=105/4
=26
Answer:
No graph so we'll use the quadratic formula
x^2+x-4=0
a = 1
b = 1
c = -4
x = -1 +- sqr root (1^2 - 4 * 1 * -4) / 2
x = (-1 +- sqr root (1 +16) ) / 2
x1 = (-1 + sqr root (17)) / 2
x2 = (-1 - sqr root (17)) / 2

Answer:
<h3> 78%</h3>
Step-by-step explanation:
Given
Number of scientist that line in Antarctica during the winter = 1,100
Amount of scientist in the summer = 5,000
Increment = 5000 - 1100
Increment = 3900
percentage change = Increment/Original amount * 100
Percentage change = 3900/5000 * 100
Percentage change = 3900/50
Percentage change = 78%
<em>Hence the percent change in the number of scientists living in Antarctica is 78%</em>
Answer:
y =
x - 6
Step-by-step explanation:
Slope intercept form is y = mx + b
To get to this form, y needs to be isolated.
So, divide each side by 5, as this will get y by itself.
5y = х – 30
y =
x - 6 is the equation in slope intercept form
