Answer: -13
Step-by-step explanation:
c-2y
= -5-2(4)
= -5 - 8
= -13
Answer:
k=2/3
Step-by-step explanation:
Step 1:
Step 1 in solving the exponential equations is re-writing the base same as other side of the equation
so,

Step 2:
Second step is equating the exponents
The rule used is:

So in this case

So the solution is:
k=2/3 ..
Answer:
2. quadrant 4
3. quadrant 2
4. quadrant 3
Step-by-step explanation:
You can refer to the picture.
2. Since
less than 0 which means
is negative,
less than 0 which means
is negative.
So, the angle lies in quadrant 4 (Cos quadrant)
3. Since
less than 0 which means
is negative,
less than 0 which means
is negative.
So, the angle lies in quadrant 2 (Sin quadrant)
4. Since
more than 0 which means
is positive,
less than 0 which means
is negative.
So, the angle lies in quadrant 3 (tan quadrant)
I found that Joe has 28 red pepper plants and 8 green pepper plants.
to find this, I first set up a proportion:
7/2 = (20+x)/x
then you cross multiply giving you:
7x = 40 + 2x
Subtract 2x from both sides:
5x = 40
solve for x:
x = 8 (which is the amount of green pepper plants)
to find how many red pepper plants he has, plug in x for (20 + x) giving you 28 red pepper plants
Hope I helped :)
I got x = 4-2y
4x+8y=16
-8y=-8y
4x=16-8y
— ——-
4 4
x=4-2y
