Answer:
-3/4
Step-by-step explanation:
Write in y = mx + b form
4y = -3x + 8
y = -3/4x + 2
Find the m value.
m = -3/4
Answer:
20 lbs
Step-by-step explanation:
is heidi dieting cuz thats good!
4 lbs x 5 months = 20 lbs
118 ounces because 1 pound equals 16 ounces
Answer:
y"(2, 1) = -5
Step-by-step explanation:
Step 1: Define implicit differentiation
5 - y² = x²
Step 2: Find dy/dx
- Take implicit differentiation: -2yy' = 2x
- Isolate y': y' = 2x/-2y
- Isolate y': y' = -x/y
Step 3: Find d²y/dx²
- Quotient Rule: y'' = [y(-1) - y'(-x)] / y²
- Substitute y': y" = [-y - (-x/y)(-x)] / y²
- Simplify: y" = [-y - x²/y] / y²
- Multiply top/bottom by y: y" = (-y² - x²) / y³
- Factor negative: y" = -(y² + x²) / y³
Step 4: Substitute and Evaluate
y"(2, 1) = -(1² + 2²) / 1³
y"(2, 1) = -(1 + 4) / 1
y"(2, 1) = -5/1
y"(2, 1) = -5
Answer:
x=2
Step-by-step explanation:
5(7-x)-3(x+4)-4=4(x-3)+7
35-5x-3x-12-4=4x-12+7
19-8x=4x-5
+8x. +8x
24=12x
x=2
