Hard for me to see the topic what is it called and what are you struggling with
Answer:
y=-4/23
im not sure i didn't check (might be wrong)
Step-by-step explanation:
4x - 5y = -28
-3x - 2y = 10
then make x the same
So
12x-15y=-84
-12x-8y=80
then its left with
-23y=-4
y=-4/23
find x by entering y into -3x - 2y = 10 and solving
restrict the domains of quadratic functions and absolute value functions, because these functions are
functions. For instance, the quadratic function f(x) = x^2 pairs both −2 and 2 with 4, and the absolute value function f(x) = |x| pairs both −2 and 2 with 2.
Linear functions (excluding constant functions) and exponential functions are
functions, so their domains
to be restricted.
_________________
An absolute value function, without domain restriction, has an inverse that is NOT a function.
In order to guarantee that the inverse must also be a function, we need to restrict the domain of the absolute value function to make it a one-to-one function.
Answer:
40 miles is her goal.
Step-by-step explanation:
The problem says that 24 miles is 60% of her goal for that month.
You cab make a proportion with x being the goal for the whole month.
24/x = 6/10
You cross multiply and get:
6x = 24 x 10
6x = 240
x = 40
40 miles is the answer.
