Sin(x)=cos(90-x); therefore x=68º
Answer:
Step-by-step explanation:
<u>Use two pairs of points to work out the equation: </u>
<u>Find the slope:</u>
- m = (5 - 1) / (2 - 1) = 4/1 = 4
<u>Find the y-intercept:</u>
- 1 = 4*1 + b
- b = 1 - 4
- b = - 3
<u>The line is:</u>
Correct choice is D
-15 is 15 below o
you are adding 4 , so you are getting closer to 0
so you would actually use subtraction, 15-4 = 11
since 15 is negative, and you are adding a number smaller than 15, the answer would be negative so it would be -11

Answer:
He gets $10 for his weekly allowance.
Step-by-step explanation:
Let x represent the amount that Fred gets for his allowance weekly.
Fred spent half his allowance on the movies. This means that the total amount that he spent on the movies is x/2. The amount that he is left with would be
x - x/2 = x/2
He washed the family car for six dollars. This means that the total amount that he is left with would be
x/2 + 6
if he now has eleven dollars, it means that
x/2 + 6 = 11
x/2 = 11 - 6 = 5
x = 2 × 5 = $10
