Salma's coffee shop makes a blend that is a mixture of two types of coffee. type a coffee costs salma $5.95 per pound, and type

Luda [366]

For this case, the first thing we must do is define variables.
We have then:
x = pounds of type a coffee
y = pounds of type b coffee
We now write the system of equations:
5.95x + 4.45y = 490.05
y = 2x
Solving the system of equations we have:
x = 33
y = 66
Answer:
were used 33 pounds of type a coffee

Write an explicit formula for an,the Nth term of the sequence 4,12,36

Rudik [331]

Answer:

$3^{n}+3^{n-1}$

Step-by-step explanation:

Since the sequence is geometric (it multiplies the previous number each time). The nth term sequence would be $x^n + yn$

Because the sequence multiplies by 3 each time, The base number in that equation would be $3^n +yn$ .

So $3^n$ of the equation would be:
$3, 9, 27$ .

Compare the 2 equations:
4, 12, 36

3, 9 ,27

The difference between the 2 equations is: 1, 3, 9 which itself is a geometric sequence so the nth term of this new equation is: $3^{n-1}$ .

Combine these 2 equations together and you get:

$3^{n}+3^{n-1}$ .

Determine the equation of the line that is perpendicular to the given line, through the given point.

exis [7]

Answer:

The equation of the line is $y + 7 = -\frac{1}{3}(x - 9)$

Step-by-step explanation:

Equation of a line:

The equation of line, in point-slope form, is given by:

$y - y_0 = m(x - x_0)$

In which m is the slope and the point is $(x_0, y_0)$

Perpendicular lines:

If two lines are perpendicular, the multiplication of their slopes is -1.

Through (9,-7)

This means that $x_0 = 9, y_0 = -7$

So

$y - y_0 = m(x - x_0)$

$y - (-7) = m(x - 9)$

$y + 7 = m(x - 9)$

Perpendicular to y = 3x + 4

This line has slope 3, so:

$3m = -1$

$m = -\frac{1}{3}$

Thus

$y + 7 = m(x - 9)$

$y + 7 = -\frac{1}{3}(x - 9)$

Will give brainliest answer

Ann [662]

Answer:

not equivalent

equivalent

not equivalent

Step-by-step explanation:

25 is by itself already 5²

therefore

${25}^{m} = {5}^{2m}$

when we divide one time by 5, we simply take away 1 from the power making it

${5}^{2m - 1}$

the other options are wrong

${25}^{m - 1}$

would be right, if we have

${25}^{m} \div 25$

but we don't.

and

${25}^{2m - 1}$

would even square

${25}^{m}$

and then divide by 25. no, the original excision is nothing like that.
