The simplified form of the expression 7^x+1 + 7^x / 2×7^x as given in the task content follows from the laws of indices and is equal to; 4.

<h3>What is the simplified form of the expression 7^x+1 + 7^x / 2×7^x?</h3>

It follows from the task content that the expression whose simplified form is to be determined is given as; 7^x+1 + 7^x / 2×7^x.

On this note, it follows from the law of indices that; 7^x+1 = 7× 7^x.

Hence, we have; 7^x(7+1 ) / 2×7^x.

And upon simplification, we have; 8/2 = 4.

Consequently, we may conclude that the simplified form of the expression as given in the task content is; 4.

Answer:

The final equation is $y = \frac{4}{3}x - \frac{16}{3}$

Step-by-step explanation:

The slope of the line CB where, C(0,3) and B(12,-6) will be

$M = \frac{- 6 - 3}{12 - 0} = - \frac{3}{4}$

Now, if the line perpendicular to the line CB has slope N, then M × N = - 1

⇒ $N = \frac{4}{3}$ {Since $M = - \frac{3}{4}$ }

Now, equation of the straight lines which are perpendicular to CB will be in slope-intercept form

$y = \frac{4}{3}x + c$ {Where, c is the y-intercept}

If this straight line passes through the point (7,4), then

$4 = \frac{4}{3} \times 7 + c$

⇒ 12 = 28 + 3c

⇒ 3c = - 16

⇒ $c = - \frac{16}{3}$

Therefore, the final equation is $y = \frac{4}{3}x - \frac{16}{3}$ (Answer)

Answer:

Answer:

Total number of cards = 32(4) or y=32(4)

Roberto had 128 cards.

Step-by-step explanation:

Consider the provided information.

Part (A)

He gave his four friends 32 baseball cards each.

Let the number of cards he have before giving them to his friends is y.

This can be written as:

y = 32(4)

Part (B)

Now solve the above equation as shown.

y = 32(4)

Multiply 32 with 4

y = 128

Hence, Roberto had 128 cards.
