Answer:

Plot the following points on the graph

$(-1, \frac{1}{2})$ , (0, 1), (1, 2), (2, 4), (3, 8)

Step-by-step explanation:

If the equation for the line is y = $2^{x}$ , whatever the power/exponent "x" equals, then y is equal to however many times 2 is multiplied by x.

For example, if our domain is {-1, 0, 1 , 2, 3}

then we would plug in each x value into the exponent to find the y-value in order to plot the points to solve the problem.

If x = -1, then y = 1/2. **If there is an a negative exponent it would get turned into a positive fraction with the denominator as the positive version of that number.

$y = 2^{-1} = \frac{1}{2^{1} } = \frac{1}{2}$

If x = 0, then y = 1

**When the exponent is 0, the number automatically equals 1.

If x = 1, then y = 2.

If x = 2, then y = 4

If x = 3, then y = 8

So you would plot the following coordinates on the graph:

$(-1, \frac{1}{2})$

(0, 1)

(1, 2)

(2, 4)

(3, 8)

A recipe that makes 8 jumbo blueberry muffins calls for 1 1/2 teaspoons of baking powder how much making baking powder is needed

nirvana33 [79]

we know that

For make $8$ jumbo blueberry muffins is needed $1\frac{1}{2}$ teaspoons of baking powder

$1\frac{1}{2}=1.5$

by proportion

$\frac{8}{1.5} =\frac{36}{x} \\ \\ 8x=36*1.5\\ \\ x=\frac{36*1.5}{8} \\ \\ x=6.75$

$x=6\frac{3}{4}$ teaspoons of baking powder

therefore

the answer is

$6\frac{3}{4}$ teaspoons of baking powder

Find an equation of the line. Write the equation in function notation. Through (6,-1); perpendicular to 9y=x-18

docker41 [41]

The first step is to find the slope of the given line by putting its equation in the form y = mx + b.
9y = x - 18
Dividing both sides by 9, gives:
y = (x/9) - 2
The slope of the given line is therefore 1/9.
Let the slope of the perpendicular line be m.
The product of the two slopes must equal -1 for the lines to be perpendicular.
$m\times\frac{1}{9}=-1$
Therefore m = -9.
At this stage the equation of the required line is y = -9x + b.
Now we need to find the value of b.
Plugging the given values of a point on the line (6, -1) into the equation gives:
-1 = -54 + b; from which b = 53.
The required equation for the line is:
f(x) = -9x + 53.
