Answer:

To solve the equation, you have to to isolate the variable. So, first you subtract both sides by 7.

x +7 - 7 = -2 - 7

When you simplify further,

x = -9.

Hope this helps! :)

The graph of function f is shown. Function g is represented by the equation. Look at the graph and picture!
lana66690 [7]

Answer: B) different y intercepts; same end behavior

=======================================================

Explanation:

The graph shows the y intercept is 4 as this is where the green curve crosses the vertical y axis.

The y intercept of g(x) is 6 which can be found by plugging x = 0 into the g(x) function

g(x) = 4(1/4)^x + 2

g(0) = 4(1/4)^0 + 2

g(0) = 6

So we can see the y intercepts are different.

----------

However, the end behaviors are the same for each function. The left side of f(x) goes up forever to positive infinity. The same is true for g(x). You could use a graphing calculator or a table to see this. As x heads to negative infinity, y goes to positive infinity.

In terms of symbols, x \to -\infty, y \to \infty

----------

For the right side of f(x), it slowly approaches the horizontal asymptote y = 2. It never actually reaches this y value. The same happens with g(x). The portion 4(1/4)^x gets smaller but never gets to 0 so overall 4(1/4)^x+2 gets closer to 2. We can say that as x approaches infinity, y approaches 2.

In terms of symbols, x \to \infty, y \to 2

Gary spends 10 per week on the internet and 13 hours per week playing video games. If Gary has five hours of free time per day w
Natalka [10]

Answer:

460% of free time is spent on internet and games .

Step-by-step explanation:

Given as :

The time spent by Gary on internet = 10 hours per week

The time spent by Gary on video games = 13 hours per week

So, Total time spent by Gary = 10 hours per week + 13 hours per week

                                                = 23 hours per week

The free time which Gary have = 5 hours

Now, percentage of free time spent on internet and games = x %

So, x % of 5 = 23

or, x % = \frac{23}{5}

∴  x% = 4.6

I.e x = 460 %

Hence  460% of free time is spent on internet and games . Answer

The population of a type of local dragonfly can be found using an infinite geometric series where a1 = 65 and the common ratio i
hram777 [196]
In mathematics, number sequencing of the same pattern are called progression. There are three types of progression: arithmetic, harmonic and geometric. The pattern in arithmetic is called common difference, while the pattern in geometric is called common ratio. Harmonic progression is just the reciprocal of the arithmetic sequence.

The common ratio is denoted as r. For values of r<1, the sum of the infinite series is equal to

S∞ = A₁/(1-r), where A1 is the first term of the sequence. Substituting A₁=65 and r=1/6:

S∞ = A₁/(1-r) = 65/(1-1/6)
S∞ = 78
