Three times a number minus thirty-two
lbvjy [14]

Answer:

3n−32=7n+28

n=-15

Step-by-step explanation:

Let's solve your equation step-by-step.

3n−32=7n+28

Step 1: Subtract 7n from both sides.

3n−32−7n=7n+28−7n

−4n−32=28

Step 2: Add 32 to both sides.

−4n−32+32=28+32

−4n=60

Step 3: Divide both sides by -4.

−4n/−4=60/−4

n=−15

f(x) = square root ( x^4 -16x^2) let f be the function given by: . . a) Find the domain of f.. b) Find f '(x). c) Find the slope
Bond [772]
A ) The domain:
x^{4} -16 x^{2}  \geq 0 \\  x^{2} ( x^{2} -16) \geq 0 \\  x^{2} -16 \geq 0 \\  x^{2}  \geq 16
x ≤ -4  and x≥ 4  or:  x ∈ ( - ∞ , - 4 ) ∪ ( 4  , + ∞ )
b ) f ` ( x ) = \frac{1}{2 \sqrt{ x^{4} -16 x^{2} } } *( 4 x^{3} - 32 x ) = \\ = \frac{2x( x^{2} -8)}{ \sqrt{ x^{4}-16 x^{2}  } }
c ) The slope of the line normal to the graph at x = 5
m = -1 / f `(x)
f ` ( x ) = \frac{10(25-8)}{ \sqrt{625-400} }=  \frac{10*17}{15} = \frac{34}{3}
m = - 3/34

Jackson loves to take day trips during weekends. Last weekend, he drove 80 miles to Crabclaw Beach. He used 4 gallons of gas to
ra1l [238]

Answer:

5 gallons of gas

Step-by-step explanation:

From the above question:

If:

80 miles = 4 gallons of gas

100 miles = x gallons of gas

Cross Multiply

80 × x = 100 × 4

x = 100 × 4/80

x = 5 gallons of gas

Therefore, Jackson would use 5 gallons of gas to get to Mount Highmore.
