Answer:

Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=x3+73 f - 1 ( x ) = x 3 + 7 3 is the inverse of f(x)=3x−7 f ( x ) = 3 x - 7 .

8(h-1)=6h+4+2h solve for h

Dima020 [189]

Answer:

No Solution

Explanation:

Given the equation:

$8\mleft(h-1\mright)=6h+4+2h$

Step 1: Distribute the terms in the left-hand side.

$8h-8=6h+4+2h$

Step 2: Collect like terms.

$\begin{gathered} 8h-6h-2h=4+8 \\ 0=12 \\ \text{But:} \\ 0\neq12 \end{gathered}$

Therefore, the equation has No Solution.

3x + 4y= 16 solve for y

Pepsi [2]

3x + 4y = 16
<u>- 3x -3x</u>
4y = -3x + 16 (divide each side by 4)
$\frac{4y}{4} = \frac{-3x+16}{4}$
y = -3/4x + 16/4

The answer is $y =- \frac{3}{4}x +4$

(All yes or no questions). Determine whether each of the following pairs of angles have equal measures:

erica [24]

9514 1404 393

Answer:

a) no

b) yes

c) yes

d) no

Step-by-step explanation:

Angle LJM is complementary to KJL, so is ...

angle LJM = 90° -42° = 48°

Angle NJP is marked as congruent to angle PJQ, so is also 48°.

a) ∠KJL = 42° ≠ 48° = ∠LJM . . . . NO

b) ∠MJP = 46°+48° = 48° +46° = ∠PJR . . . . YES

c) ∠LJP = 48° +46° +48° = 48° +48° +46° = ∠NJR . . . . YES

d) ∠MJK = 90° ≠ 48° +46° = ∠PJR . . . . NO
