Answer:
I solve it by substitution
y=x^2+4x
-x^2+9x+(x^2+4x)+13=0
13x+13=0
13x=-13
x= -13/13
x= -1
y=x^2+4x=1-4
y= -3
Step-by-step explanation:
Answer:
x ≤ 204 crates
Step-by-step explanation:
Greatest weight of the container = 27500 kilograms
Weight of other shipment = 7100 kilograms
Weight of crates = 100 kilogram
x = number of 100 kilogram crates that can be loaded into the shipping container.
The inequality:
27500 ≤ 7100 + 100x
27500 - 7100 ≤ 100x
20,400 ≤ 100x
x ≤ 20,400 / 100
x ≤ 204 crates of 100 kilogram
Answer:
1. Use the distributive property to get rid of any parenthesis.
2. Combine like terms
3. Move all variables to one side
4. Inverse operations
Hey man, refer the attachment.
Count the squares from one point to the end point. X=4, Y=2. Formula of a slope is y/x. 2/4 or 1/2.
