Answer:

x = -2

Step-by-step explanation:

Step 1: Subtract 7 from both sides.

3x+7−7=1−7

3x=−6

Step 2: Divide both sides by 3.

3x/3 = −6/3

x = −2

The table represents a linear function. Find the values of A and B.

bazaltina [42]

Answer:

The answers are that a = -5 and b = 1

Step-by-step explanation:

In order to find A and B, we first need to find the equation of the line. We can do this by using two ordered pairs and the slope formula. For the purpose of this activity, I'l use (0, 5) and (-3, 11)

m(slope) = (y2 - y1)/(x2 - x1)

m = (11 - 5)/(-3 - 0)

m = 6/-3

m = -2

Now that we have this we can model this using point-slope form.

y - y1 = m(x - x1)

y - 5 = -2(x - 0)

y - 5 = -2x

y = -2x + 5

Now that we have the modeled equation we can use the ordered pair (a, 15) to solve for a.

y = -2x + 5

15 = -2(a) + 5

10 = -2a

-5 = a

And we can also solve for b using the ordered pair (2, b)

y = -2x + 5

b = -2(2) + 5

b = -4 + 5

b = 1

Solve for x 2/(7x) = 6/5 5/21 -21/5 21/5 I don't know - 5/21

djverab [1.8K]

The answer is: [A]: " $\frac{5}{21}$ " .
________________________________________
Given:

2/ (7x) = 6/5;

→ (6/5) * (7x) = 2 ;

42x / 5 = 2 ;

42x = 2*5 ;

42x = 10 ;

42x /42 = 10/42 ;

x = 10/42 = (10÷2) / (42÷2) = 5/21 ;

x = $\frac{5}{21}$ ;

→ which is: Answer choice: [A]: " $\frac{5}{21}$ " .
