Answer:
(x, y) = (- 3, - 2)
Step-by-step explanation:
given the 2 equations
5x + 7y = - 29 → (1)
y = x + 1 → (2)
substitute y = x + 1 into (1)
5x + 7(x + 1) = - 29 ( distribute and simplify left side )
5x + 7x + 7 = - 29
12x + 7 = - 29 ( subtract 7 from both sides )
12x = - 36 ( divide both sides by 12 )
x = - 3
substitute x = - 3 into (2)
y = - 3 + 1 = - 2
solution is (- 3, - 2 )
Answer:
the answer is : 6.25
Step-by-step explanation:
you just 3+ (4x(0.5) the -o.75) +2

The simplified expression of is .
Solution:
Given expression is .
To simplify the given expression.
Using exponent rule:
Using another exponent rule:
Using exponent rule:
Hence the simplified expression of is .
(30)(x%) = 18
x = 18 / 30
x = 0.6
x = 60%
Hope this helps!
Answer:
There will be 96 lemmings in 7 years
Step-by-step explanation:
we have
This is a exponential function
where
x ------> the time in years
f(x) ----> lemming population
so
For x=7 years
substitute in the function
There will be 96 lemmings in 7 years
