Tangent slope of 4x^2+2x when x=-2
polet [3.4K]

Answer:

-14

Step-by-step explanation:

f(x) = 4x² + 2x

Take the first derivative:

f'(x) = 8x + 2

Evaluate at x = -2:

f'(-2) = 8(-2) + 2

f'(-2) = -14

The tangent slope is -14.

the sum of the digits of a two-digit number is 14. the first digit is 4 less than twice the second digit. what is the number
Blizzard [7]

Answer:

86

Step-by-step explanation:

t = ten's digit    u= one's digit

t + u = 14            t = 2u - 4

In the first equation substitute for t 2u - 4 that we find in the second equation above.

t + u = 14

2u - 4 + u = 14  Combine the u's

3u - 4 = 14  Now add 14 to both sides

3u = 18  Divide both sides by 3

u = 6.  We found the unit's digit, now we will find the ten's unit by plugging in 6 for u in the first equation above.

t + u = 14

t + 6 = 14  Subtract 6 from both sides

t = 8

So, your answer is 86.

Ac=5x+2,bc=x+3,ab=3x+4
tensa zangetsu [6.8K]
Ab + bc = ac
3x + 4 + x + 3 = 5x + 2
4x + 7 = 5x + 2
7 - 2 = 5x - 4x
5 = x <==

ab = 3x + 3....3(5) + 4 ....15 + 4 = 19
bc = x + 3 ...5 + 3 = 8
ac = 5x + 2....5(5) + 2.....25 + 2 = 27
