1. 4x + 3(x-9) = 19

Dmitry_Shevchenko [17]

1) 4x + 3(x-9) = 19

or, 4x + 3x - 27 = 19

or, 7x = 19+27

or, 7x = 46

or, x = 46/7

◆ x = 6.57

2) 2(x-4) + 5x = 3

or, 2x - 8 + 5x = 3

or, 7x = 3+8

or, x = 11/7

◆ x = 1.57

3) 60 = 8y - 3(y-10)

or, 60 = 8y - 3y + 30

or, 60 - 30 = 5y

or, y = 30/5

◆ y = 6

4) 40 + 3c = 3 + 9(c-2)

or, 40 + 3c = 3 + 9c - 18

or, 40 + 3c = 9c - 15

or, 9c - 3c = 40 + 15

or, 6c = 55

◆ c = 9.166

I hope you understand..

If f(x) = k where k is a constant, and the points (6,1) and (8,1) lie on the graph of y = f(x), what is the value of f(0)?

Colt1911 [192]

Answer:

The value of f(0)=1

Step-by-step explanation:

We are given that

$f(x)=k$

$y=f(x)$

(6,1) and (8,1) lies on the graph of y=f(x)

We have to find the value of f(0).

$f(6)=1$

$f(8)=1$

$f(x)=k$

By comparing ,we get

k=1

Therefore, $y=f(x)=1$

Now, substitute x=0

$f(0)=1$

Hence, the value of f(0)=1

Kesley is thinking of a number. She says that it’s the sum of a number and nine. Multiplied by 2/3, is equal to -18.

Aliun [14]

Answer:

Only the firsts and fourth choices ( $\frac{2}{3}(x+9)=-18$ and $\frac{2}{3}x+6=-18$ )

Step-by-step explanation:

Turn the equation into words:

"A number plus 9"

$(x+9)$

"Multiplied by $\frac{2}{3}$ "

$\frac{2}{3} (x+9)$

"Is equals to -18"

$\frac{2}{3}(x+9)=-18$

Distribute to find the second equation:

$\frac{2}{3}(x+9)=-18\\\frac{2}{3}x+6=-18$
