Pleaseeee help with this question
prove (1-cos^2A)csc^2A=1
For all x,
sin²(x) + cos²(x) = 1
so we have
(1 - cos²A) csc²A = sin²A csc²A
and since csc(x) = 1 / sin(x), so the expression reduces to 1.

Solve 4(x + 1) = 4x + 4.
A) No solution
B) 0
C) All real numbers
D) 1
Please help, and explain how you got the answer :)!
Answer:
all real numbers
Step-by-step explanation:
Simplifying
4(x + 1) = 4x + 4
Reorder the terms:
4(1 + x) = 4x + 4
(1 * 4 + x * 4) = 4x + 4
(4 + 4x) = 4x + 4
Reorder the terms:
4 + 4x = 4 + 4x
Add '-4' to each side of the equation.
4 + -4 + 4x = 4 + -4 + 4x
Combine like terms: 4 + -4 = 0
0 + 4x = 4 + -4 + 4x
4x = 4 + -4 + 4x
Combine like terms: 4 + -4 = 0
4x = 0 + 4x
4x = 4x
Add '-4x' to each side of the equation.
4x + -4x = 4x + -4x
Combine like terms: 4x + -4x = 0
0 = 4x + -4x
Combine like terms: 4x + -4x = 0
0 = 0
Solving
0 = 0
Couldn't find a variable to solve for.
This equation is an identity, all real numbers are solutions.

Step-by-step explanation:
Write the following equation in slope -intercept form : y - 3 = 4(x + 2)
Answer:
y=4x+11
Step-by-step explanation:
multiply 4 into the parentheses to get y-3=4x+8 then invert -3 so add three to both sides to get rid of it so instead of +8 its +11 so now its y=4x+11 and slope intercept is y=mx+b, so 4 is m, slope, and 11 is b, the y intercept i hope that helps

Step-by-step explanation:
Answer:
7x - 18 = 24
Step-by-step explanation:
So solve the problem:
7x - 18 = 24
7x - 18 - 18 = 24 + 18 ( subtract 18 from the left side and add it to the right )
7x = 42
7x / 7 = 42 / 7 ( divide both sides by 7 and the answer is 6)
x = 6 ( so x is equal to 6 )

What is the slope of a line that is parallel to the graph of x + 3y = 5?
Answer: -1/3
Step-by-step explanation: If its parallel, the slope will be flipped, so the new slope is -1/3.
Answer:
Step-by-step explanation:
Two lines are parallel if the have the same slope. Example 1: Find the slope of the line parallel to the line 4x – 5y = 12. To find the slope of this line we need to get the line into slope-intercept form (y = mx + b), which means we need to solve for y: The slope of the line 4x – 5y = 12 is m = 4/5.
A trucking company wants to evaluate whether a decrease in the weight of their trucks helps to increase gas mileage.

Which statement or statements accurately describe a good way to avoid excessive service fees?
1. Try to deposit money in large batches rather than in small amounts.
II. Try to limit the number of withdrawals you make from out-of-network ATMs.
III. Try to avoid using your debit card online.
a. I and II
b. ll only
c. Ill only
d. I and III
Answer:
b. ll only
Explanation:
Remember, service fees often refer to an amount deducted to pay for the cost of providing particular services, such as ATM service charges, etc.
We can this conclusion because if one decides to deposit money in large batches rather than in small amounts; they will be directly subjecting themselves to excessive charges. Consider, most financial institutions often charge higher fees for larger deposits.
Also, if one decides to avoid using your debit card online they will tend to spend more using traditional cash methods which require increasing the number of one's ATM withdrawal.
However, by trying to limit the number of withdrawals you make from out-of-network ATMs, one saves him or herself of excessive service fees.

When randomly selecting adults, let M denote the event of randomly selecting a male and let B denote the event of randomly selecting someone with blue eyes. What does P (M|B) represent?
(A) The probability of getting someone with blue eyes, gven that a male has been selected
(B) The probability of getting a male and getting someone with blue eyes.
(C) The probability of getting a male or getting someone with biue
(D) The probability of getting a male, given that someone with blue ayes has been selected
Is P(M|B) the same as P(B|M)?
(A) No, becase P(BIM) represents the probabity of getting a male, given that someore with blue eyes as been selected(B) No, because P(BIM) represents the probability of getting someone with blue eyes, given that a male has been selected
(C) Yes, because P(BIM) represents the probability of getting a male, given that someone with blue eyes has been selected
(D) Yes, because P(BIM) represen
Answer:
(D) P (M|B) represents the probability of getting a male, given that someone with blue eyes has been selected.
(B) No, because P(BIM) represents the probability of getting someone with blue eyes, given that a male has been selected.
Step-by-step explanation:
Given that, M denotes the event of randomly selecting a male and B denotes the event of randomly selecting someone with blue eyes.
So, P (M|B) represents the probability of getting a male, given that someone with blue eyes has been selected.
While P(B|M) represents the probability of getting someone with blue eyes, given that a male has been selected, so, P(M|B) and P(B|M) are not the same.
