Answer:
Step-by-step explanation:
m has a slope of -2 and a y intercept of 4
y = -2x + 4
n has a slope of 1 and a y intercept of -1
y = 1x - 1
y = x - 1
Ah!... the invisible questions in a sideways posted image.
t has a slope of zero and a y intercept of 3
y = 0x + 3
y = 3
p has infinite slope and no y intercept.
x = -5
Answer:
x = π/2 + πk
Step-by-step explanation:
cot² x csc² x + 2 csc² x − cot² x = 2
Multiply both sides by sin² x:
cot² x + 2 − cos² x = 2 sin² x
Add cos² x to both sides:
cot² x + 2 = 2 sin² x + cos² x
Pythagorean identity:
cot² x + 2 = sin² x + 1
Subtract 1 from both sides:
cot² x + 1 = sin² x
Pythagorean identity:
csc² x = sin² x
Multiply both sides by sin² x:
1 = sin⁴ x
Take the fourth root:
sin x = ±1
Solve for x:
x = π/2 + 2πk, 3π/2 + 2πk
Which simplifies to:
x = π/2 + πk

You has some spelling errors, im guessing this is what you ment :
<span>Lee's muffin mix calls for 2/3 cup of milk, 1/3 Cup of oil and 1/3 cup of sugar. How much more milk than oil does she need for the muffin mix
</span><span>Answer : She needs 1/3 cup more milk than oil
to figure this out do 2/3 - 1/3 = 1/3</span>
This is a stupid question. The teacher who asked this needs to go back to school.
A = x⁴ - 9y²
That's going to be a number. As long as it's positive we can choose any length for our rectangle L and we can compute the width by W=A/L. So the correct answer is the dimensions are L by (x⁴ - 9y²)/L.
They don't want the correct answer. They want you to factor this expression. We'll do it, but don't believe for a second this factoring somehow constrains the possible dimensions of some rectangle.
We use the difference of two squares, a²-b² = (a+b)(a-b)
A = x⁴ - 9y² = (x²)² - (3y)² = (x²+3y)(x²-3y)
Answer: x²+3y by x²-3y
