Answer:
Hey there!
We are trying to find the difference between 4 and -7
We can write -7+x=4, where x is the difference we are trying to find.
Solving for x, we get that the difference is 11.
Let me know if this helps :)
Linear are straight, exponential are curved. Linear functions just have an x, while exponential can have an x^2.
Linear functions have a constant slope, exponential do not.
45 total means
45=boys+girls
if 3/5 are boys then
3/5 area boys
3/5 of 45=boys
'of' can be translated as multiply for fractions
3/5 times 45=135/5=27
27 are boys
45=b+g
b=27
subsitute
45=27+g
subtract 27 from both sides
18=g
18 girls
27 boys
18 girls
