Answer:
-70
Step-by-step explanation:
subtract 47 from both sides to get
x = -23 - 47
Answer:
Options B and D.
Step-by-step explanation:
The general form of sine function

where, |A| is amplitude,
is period,
is phase shift and D is y-intercept.
The general form of cosine function

where, |A| is amplitude,
is period,
is phase shift and D is y-intercept.
In function, 
Amplitude : 
y-intercept : -1
In function, 
Amplitude : 
y-intercept : -1
In function, 
Amplitude : 
y-intercept : 0
In function, 
Amplitude : 
y-intercept : -1
Therefore, the correct options are B and D.
Hayden's hourly rate is $30
Extra hour rate is 1.5×30=$45
given that he earned $2175 by working 40 regular hours, the number of overtime hours he worked will be given as follows;
let the number of overtime be x
hence total amount earned will be:
(40×30)+(45×x)=2175
1200+45x=2175
45x=2175-1200
45x=975
solving for x we get
x=975/45
x=65/3=21 2/3 hours
5 × 9 = 45
Hope this helps!
Answer:
d. 15, 30, 135
Step-by-step explanation:
A triangle's interior angles on a flat surface add up to 180 degrees.
a. 90 * 3 = 270 != 180
b.(80 * 2) + 200 = 360 != 180
c.40 + 50 + 60 = 160 != 180
d.15 + 30 + 135 = 45 + 135 = 180, so it has to be d.
