Answer:

(10x+5)-(-23-2x)=

10x+5+23+2x

=12x+28

2x+5x^2-(3x+7x^2)=

2x+5x^2-3x-7x^2

= -2x^2-1

Basic Power Rule:

f(x) = cxⁿ
f’(x) = c·nxⁿ⁻¹

Step-by-step explanation:

Step 1: Define

$\displaystyle y = \frac{3}{2x^2}$

$\displaystyle \text{Point} \ (1, \frac{3}{2})$

Step 2: Differentiate

[Function] Rewrite [Exponential Rule - Rewrite]: $\displaystyle y = \frac{3}{2}x^{-2}$
Basic Power Rule: $\displaystyle y' = -2 \cdot \frac{3}{2}x^{-2 - 1}$
Simplify: $\displaystyle y' = -3x^{-3}$
Rewrite [Exponential Rule - Rewrite]: $\displaystyle y' = \frac{-3}{x^3}$

Step 3: Solve

Substitute in coordinate [Derivative]: $\displaystyle y'(1, \frac{3}{2}) = \frac{-3}{1^3}$
Evaluate exponents: $\displaystyle y'(1, \frac{3}{2}) = \frac{-3}{1}$
Divide: $\displaystyle y'(1, \frac{3}{2}) = -3$

Find the 30th term of the following sequence. 1, 7, 13, 19,.. 174. 175. 180. 181.

shepuryov [24]

The first term a = 1,

Common difference, d: 7 - 1 = 6.

a(n) = a + (n -1)d,

For 30th term. = 1 + (30 -1)*6

= 1 + 29*6 = 1 + 174 = 175

GEOMETRY HELP WILL MARK BRAINLIEST

alisha [4.7K]

Answer:

x=8

z = 115

Step-by-step explanation:

65 and 13x - 39 are vertical angles so they are equal

65 = 13x - 39

Add 39 to each side

65+39 = 13x - 39+39

104 = 13x

Divide each side by 13

104/13 = 13x/13

8 =x

65 and z are supplementary angles because they form a straight line. This means they add to 180

65+z = 180

Subtract 65 from each side

65+z-65 = 180-65

z = 115
