Answer:

8a^3

Step-by-step explanation:

Given that;

2^x = a, we want an expression for 8^(x + 1)

we have this as;

8^(x + 1) = 8^x * 8^1

8^x = (2^x)(3)

8^x is thus same as 2^3x

So replace 2^x by a

Thus, we have a^3

Multiply this by the 8 we had initially; that will give;

8 * a^3 = 8a^3

Which linear equation best represents the data given in the table?
kirill115 [55]

Linear equations are equations that have constant slopes

The linear equation that represents the table is (a) y = 7x +4

<h3>How to determine the linear equation</h3>

Start by calculating the slope (m) using:

m = \frac{y_2 -y_1}{x_2 -x_1}

So, we have:

m = \frac{-10 +17}{-2 +3}

Simplify

m = \frac{7}{1}

m = 7

The equation is then calculated as:

y = m(x -x_1) + y_1

So, we have:

y = 7(x +2) -10

Open the brackets

y = 7x +14 -10

y = 7x +4

Hence, the linear equation that represents the table is (a) y = 7x +4

To find the x-intercept, we let y = 0 and solve for x and to find y-intercept, we let x=0 and solve for y. Figure out the x-inte
Dima020 [189]

Answer:

<h2>         X-intercept: (2, 0) </h2><h2>         Y-intercept: (0, 6) </h2>

Step-by-step explanation:

X-intercept means y-coordinate of 0:

6x +2×0 = 12

6x = 12

  x = 2         ← x-coordinate

Y-intercept means x-coordinate of 0:

6×0 + 2y = 12

2y = 12

  y = 6         ← y-coordinate

Show the region which satisfies simultaneously the inequalities 2x+3y≤8, x-2y≥-3, x≥0, y≥0
Verizon [17]
The first thing you should do is graph the following lines
 2x + 3y = 8
 x-2y = -3
 x = 0
 y = 0
 After you have graphed them, you should proceed to evaluate points in the xy plane that meet the following restrictions:
 2x + 3y≤8, x-2y≥-3, x≥0, y≥0
 The resulting region is the region "R" shown in the attached graph.
