Answer:
x = -2,1, 2
Step-by-step explanation:
g(x) = (x + 2)(x − 1)(x − 2)
Assuming we are looking for the roots
0 = (x + 2)(x − 1)(x − 2)
Using the zero product property
0 = x+2 0 =x-1 0 = x-2
x=-2 x = 1 x =2
Answer:
4 cm
Step-by-step explanation:
Given is an isosceles triangle. Therefore it's two sides will have equal lengths.
Let the length remaining sides be x cm.
X-intercept = (x,0) y is zero
y- intercept = (0,y) x is zero
In the equation y = -1/2 x -5
x-intercept would be
0 = -1/2 x - 5
5 = -1/2x
x = -10
y-intercept would be
y = -1/2 (0) - 5
y = -5
Thus, the answer is (-10,0) and (0,-5).
Answer:
The answer is G.
Step-by-step explanation:
The answer is G because the correct answer would be 7 plus 0.8 plus 0.03 but G. says 7 multiplied by 1 plus 8 multiplied by 0.01.
Let x = download size of the standard version.
4515 - x = download size of high quality version.
High quality was downloaded 4 times more so 4 x 4.8 = 19.2 = downloads of high quality versions.
Set up a ratio:
2.3 / 19.2 = x / 4515-x
Cross multiply:
2.3(4515-x) = 19.2x
10384.50 -2.3x = 19.2x
Add 2.3x to both sides:
10384.50 = 21.5x
Divide both sides by 21.5:
X = 10384.50/21.5
X = 483
There were 483 downloads of the standard version.
