Answer:
A. x=1, y=3
Step-by-step explanation:
2x+y= 5
2(1) + 3 = 5
2+3=5
x+y=4
1+3=4
Remove parentheses and combine like terms...
then subtract constants from both sides
isolate variables and constants
use the division property and solve for x
It seem like it's listing the factors and not the roots. If the given factors are x-2, x-(1+sqrt(5)), and x+3i
Then this means that x-(1-sqrt(5)) is another factor. So it looks like choice B is the answer. I'm using the idea that if x-(a+b*sqrt(c)) is a factor then so is x-(a-b*sqrt(c)).
Answer: 2.5 ft
Step-by-step explanation:
The volume of a rectangular prism is given by the following formula:
(1)
Where:
is the length of the base
is the width of the base
is the height of the prism
On the other hand, tha area of a rectangle is:
(2)
Then, we can rewrite (1) in terms of (2):
(3)
Now, we know the value of the volume and the area of the base:
Substituting these values in (3):
(4)
Isolating :
This is the height of the truck
Answer:
y-intercept = (0,0)
Step-by-step explanation:
To find the x-intercept, substitute in 0 for y and solve for x. To find the y-intercept, substitute in 0 for x and solve for y.
