Answer:
Angle 1=66
Step-by-step explanation:
Step 1, solve for angle 2
<2+123=180 degrees
Angle 2=57 degrees
Step 2, solve for angle 1
Since this is an isosceles triangle, to solve for angle 1, the equation is 2(57)+x=180
Angle 1=66 degrees
Answer:
Y=2.50x+3
Step-by-step explanation:
Because the $3 fee is not changing but the 2.50 is changing every pound that they get.
Example 250
word form:
two hundred and fifty
expanded form:
2+5+0
standard form:
250
The first one is 11 and -11 because when you square them they both get 121
The second one is -7 and -1
They are inverse functions though to be completely thorough your teacher should have also put g(f(x)) = x as well. Though I can see what your teacher is aiming for at least.
The idea is that whatever the output of g(x) is, it's plugged into f(x) and the initial input is the result. So g(x) takes a step forward and f(x) takes a step back undoing everything g(x) did. Which is exactly what an inverse operation does.
