Answer:
A(r)=15-3r
Step-by-step explanation:
switch the sign of +3r to make it -3r
Answer:

Step-by-step explanation:
We will use the co-function identity for sine, where:

Since sin(21)=0.358=cos(x). This means that:

Solve for x. Add x to both sides:

Subtract 21 from both sides:

Hence:

Answer:
We know, if we multiply a number x by its multiplicative inverse, the result is 1. So, 0.3 is the multiplicative inverse of 313.
Answer: b is the answer
Step-by-step explanation:
2400-1200=1200
Hello there,
To find out the equation you need to use slope intercept form...
y = mx + b
The only equation above that follows that form is...
y = 2x
Hope I helped!!
