cos(x+y) + cos(x-y) = 2cosx cosy
Answer:
Step-by-step explanation:
the given equation
cos(x+y)+cos(x-y)=2cos(x)*cos(y)
[cos(x)cos(y)-sin(x)sin(y)]+cos(x-y)=2cos(x)*cos(y) ..
[cos(x)cos(y)-sin(x)sin(y)]+[cos(x)cos(y)+sin(x)sin(y)]=2cos(x)*cos(y)
[cos(x)cos(y)+cos(x)cos(y)]]+[sin(x)sin(y)-sin(x)sin(y)]=2cos(x)*cos(y) ..
2cos(x)*cos(y)=2cos(x)*cos(y)

Which best represents the solution set of all real numbers?
[ [ PLEASE ANSWER , I'M CONFUSED ] ]
Answer:
B.
Step-by-step explanation:
Since the solution set is all real numbers, our solution graph must cover the entire number line.
We can see that B contains the graph that extends infinitely in both directions, thereby covering the entire number line.
Therefore, our answer is B.
A is not correct because it leaves out [-6, 1] (approximately).
C is not correct because it leaves out everything to the left of -7 and everything to the right of 1.

It takes 111 pounds of seed to completely plant a 12-acre field.
How many acres can be planted per pound of seed?
Answer:
0.108 Acres
Step-by-step explanation:
We find the rate by dividing the amount of acres to the pounds
12/111
= 0.108
0.108 acres of land can be planted per pound of seed

Write the equation of the line in point-slope form that has slope 3 and passes through (2, -5)
Answer:
y = 3x - 11
Step-by-step explanation:
Step 1:
y = mx + b Slope Intercept Form
Step 2:
y = 3x + b Input Slope
Step 3:
- 5 = 3 ( 2 ) + b Input x and y values
Step 4:
- 5 = 6 + b Multiply
Step 5:
- 11 = b Subtract 6 on both sides
Answer:
y = 3x - 11

It costs $5.08 for 4 pounds of gummy candy in bulk. How much would it cost to buy 17 pounds?
Answer:
$21.59
Step-by-step explanation:
Basically how I did it was to multiply 5.08 by 4, because that would be the cost of 16 bags and then I divided 5.08 by 4 to see how much one bag would cost. One bag costs 1.27. After I've got the answer, I added 1.27 to 20.32 and got $21.59.

what are the solutions to the quadratic equation 6x^2 + 24X = 0?
Answer: {0, -4}
Step-by-step explanation: Notice that the two terms on the left side
of the equation have a greatest common factor of 6x.
So start by factoring out a 6x to get 6x(x + 4) = 0.
So either 6x = 0 or x + 4 = 0.
Eventually we find that x = 0 or x = -4.
So our solution set is {0, -4}.

Enter the equation of the line in slope-intercept form.
The line passes through (1.4) and (3,18).
The equation of the line is
Answer: y = 7x - 3
graphed equation attached
Step-by-step explanation: Slope-intercept form . y= mx+b
m is the slope, b is the constant, the y-intercept.
First find the slope: rise/run
Rise is the difference in y-values 18-4 = 14
Run is the difference between x-values 3 - 1 = 2
The Slope is 14/2 simplify:
m = 7
Use this calculated slope with values of y and x from either of the given coordinates and calculate b
y = mx + b
18 = 7(3) + b
18 = 21 + b . subtract 21 from both sides 18 - 21 = 21 -21 + b
-3 = b
Put these calculated values for m and b into the slope-intercept equation"
y = 7x - b
