It looks like selections A and C are identical. (Neither is equivalent to 9^x.)

If B is supposed to be 3^(2x), it is equivalent to F and D and to the given expression.

Of course, D evaluates to 9^x, so is equivalent.

Choice E evaluates to 3^(x+2), which is not equivalent to 3^(2x).

The applicable choices appear to be

... B. 3^(2x)

... D. (3*3)^x

... F. (3^x)*(3^x)

Aleonysh [2.5K]
What is the flaw in Gina’s proof?
A) Points D and E must be constructed, not simply labeled, as midpoints.

B) Segments DE and AC are parallel by construction.  THIS IS THE FLAW. THE SEGMENTS WERE NOT DRAWN NOR PROPERLY IDENTIFIED.

C) The slope of segments DE and AC is not 0.

D) The coordinates of D and E were found using the Distance between Two Points Postulate

A cell phone provider will allow you to buy a phone over time. They require a $50 initial payment and then charge $25 per month.
kumpel [21]

Answer:

25

Step-by-step explanation:

Given that:

Initial payment done for buying the phone = $50

Charges per month for the phone = $25 per month

To find:

The equation to represent the situation and its slope.

Solution:

First of all, let us assume that m represents the number of months for which monthly is to be made.

Charges paid for one month = $25

Charges paid for m months =  $25m

Total cost of the phone = Initial payment + Charges paid for m months

C = 25m + 50

It is a linear equation between two variables C and m.

This equation can be compared with slope intercept form of a line.

Slope intercept form of a line is represented by:

y=Mx+c

M is the slope.

On Comparing, we get:

y = C, M = 25, x = m, c = 50

Therefore, the slope is <em>25</em>.

Answer:

B

Step-by-step explanation:

The square of y would look like y^2 and decreased means subtraction

So the equation now y^2-

the quotient of 8 and y would be 8/y

The full equation is y^2-8/y

Write the equation of the line through each point.
Leya [2.2K]

Answer:

The equation would be y = -1/3x + 4

Step-by-step explanation:

The first step to finding this equation needs to be solving the first equation for y so that we can find the slope.

-3x + y = 1

y = 3x + 1

Now that we have the slope of 3, we know the slope of a perpendicular line would be -1/3. This is because perpendicular lines have opposite and reciprocal slopes. We can then use this and the point to solve in point-slope form.

y - y1 = m(x - x1)

y - 2 = -1/3(x - 6)

y - 2 = -1/3x + 2

y = -1/3x + 4
