Answer:
[-3 -1]
[4 1]
Step-by-step explanation:
Inverse is the opposite so just look for the one that looks like the opposite of the first one and still solves the equation.
Answer:
Step-by-step explanation:
To create a system of equations, write an equation to model each condition that must be satisfied in the given situation.
It is given that x represents the width of the flower bed and that y represents the area of the base of the birdbath.
Write an equation to represent the condition regarding the planting area in the flower bed. It is given that there is 35 square feet of planting area. The flower bed is 3 feet longer than the width.
x(x+3) - y = 35
Write an equation to represent the condition regarding the cost of the soil and the birdbath. The question gives that the soil will cost $5 per square foot and the birdbath will cost $18 per square foot of the base.
5x(x+3)+18y=150
Combining both of the equations gives the following system of equations.
x(x+3)-y=35
5x(x+3)+18y=150
Answer: 0.42
Step-by-step explanation:
Max accidently mixed 56 turnip seeds and 78 cabbage seeds together because the two seeds look nearly
identical. The probability of choosing a turnips seed will be:
Turnip seed= 56
Cabbage seeds= 78
Total seeds= 56+78 = 134
Probability of choosing a turnips seed:
= 56/134
= 0.42
Step-by-step explanation:
try to separate each shape and then multiply every number of that shape
