So we need to find the unit rate (the denominator is 1). Divide 18 by 3 to find the amount of miles in 1 day. 18/3=6. So m=6d. To find the number of miles in 10 days, you can make an equation 1/6=10/x. x=60, so the number of miles Henry will bike in 10 days is 60 miles. Repeat with the second chart
Answer:
73.2km
Step-by-step explanation:
first you have to decompose 46 km into y and x components.
x=sin40°*46km
x=0.64*46km
x=29.44km
y=cos40°*46km
y=0.76*46km
y=34.96
now you add the y components together
32+34.96=66.98
finally use Pythagorean thereom to find the resultant vector.
a*a+ b*b=c*c
66.98*66.98+29.44*29.44=c*c
c*c= 4486.3+866.7
c=√5353
c=73.2 km this is the approximate value
Well first you multiply 66 by 3 that gives you 198+2=200 so divide 200 divide by 48
Answer:
A. 9(x + 8) = 9(x + 12)
Step-by-step explanation:
Simplify the probelm;
9(x + 8) = 9(x + 12)
Distribute;
9x + 72 = 9x + 108
Inverse opreations;
9x + 72 = 9x + 108
-9x -9x
72 = 108
This statement is not true, hence the equation has no solutions;
Answer: B
and
How to solve:
check if the composite functions of f(x) and g(x) are equal to x (this means they are inverses)
f[g(x)] = x
g[f(x)] = x
Step-by-step explanation:
Checking A.
This does not equal x, so we know these are not inverses
Checking B.
since both f(g(x)) = x and g(f(x)) = x, we can determine that they are inverses of each other.
