Suppose M is the midpoint of FG. Find the missing measure.
FM = 2k - 5, FG = 18
Answer:
k= 7
Step-by-step explanation:
if m is the midpoint of fm, and fm= 2k-5. and fg=18. then you can do: 2k-5+2k-5=18 and solve for x
The measure of FM is 9 and MG is 9.
Given,
M is the midpoint of FG.
FM = 2k - 5 and FG = 18.
We need to find the measure of MG.
What is meant by the midpoint between two points?If there is a midpoint between two points the midpoint will divide the distance between the two points into two equal halves.
AB is the distance between two points A and B
If C is the midpoint then,
AC = CB = AB / 2
We have,
FG is a line.
M is the midpoint of this line FG.
Now,
F______M______G
Since M is the midpoint we have,
We need to get,
FM = MG = FG/2
FG = FM + MG
We need to find the k value.
FM = FG/2
2k - 5 = 18/2
Multiplying 2 on both sides
4k - 10 = 18
Adding 10 on both sides
4k - 10 + 10 = 18 + 10
4k = 28
Dividing both sides by 4
k = 28/4 = 7
k = 7.
So,
FM = 2k - 5 = 2 x 7 - 5 = 14 - 5 = 9
Since M is the midpoint
FM = MG
We have,
MG = 9
We can see that,
FG = FM + MG
18 = 9 + 9
18 = 18
Thus the measure of FM is 9 and MG is 9.

I need this TONIGHT!!! Three years ago, Jolene bought $750 worth of stock in a software company. Since then the value of her purchase has been increasing at an average rate of 5 1/2% per year. How much is the stock worth now? (Round each money calculation you make to the nearest cent.) The stock is worth $ now.
Answer:
[tex]A\approx\$880.68[/tex]
Step-by-step explanation:
So, we know that Jolene bought an initial $750.
We also know that the purchase is increasing at an average rate of 5 1/2 %or 5.5%. In other words, this is being compounded.
So, we can use the compound interest formula, which is:
[tex]A=P(1+\frac{r}{n})^{nt}[/tex]
Where A is the total amount, P is the principal value, r is the rate and n is the number of times compounded per year, and t is the amount of years.
So, substitute 750 for P. 5 1/2% is the same as 5.5% or 0.055 (you move the decimal two places to the left and remove the percent symbol) so substitute this for r. Since it's increasing yearly, n is 1. So, our formula is:
[tex]A=750(1+0.055)^t[/tex]
Add:
[tex]A=750(1.055)^t[/tex]
Since the stock was bought 3 years ago, the value now is t=3. So, substitute 3 for t and evaluate:
[tex]A=750(1.055)^3[/tex]
Evaluate. Use a calculator:
[tex]A\approx\$880.68[/tex]
And we're done!
Formula: A = P(1 + r/n)^t
We have these variables:
P = 750
r/n = 0.055
t = 3
Substitute and simplify:
A = 750(1 + 0.055)^3
A = 750(1.055)^3
A = 880.68

-14 - 8x = -2(-3x + 7)
solution? No solution? Infinite?
Answer:
the answer is one solution
Answer:
x=0
This means that there is a solution.
Step-by-step explanation:
Step 1- Distribute into the parenthesis
-14-8x= (-2)-3x+(-2)7
Step 2- Multiply
-14-8x= 6x-14
Step 3- Add 8x to both sides.
-14x-8x= 6x-14
+8x +8x
Step 4- Add 14 to both sides.
-14= 14x-14
+14 +14
Step 5- Divide both sides by 14.
0 = 14x
14 14

If b is the midpoint of line AC, and AC = 8x-20, find BC.
The Definition Of a Midpoint says that is B is the
midpoint of segment AC, then segment AB ≅ AC.
Since segment AB ≅ segment BC, we can setup
the equation 2(3x - 1) = 8x - 20 and we can solve from here.
Start by distributing the 3 through the parenthses on the left side.
So we get 6x - 2 = 8x - 20.
Now subtract 8x from both sides to get -2x - 2 = -20.
Now add 2 to both sides and we have -2x = -18.
Finally, dividing both sides by -2, we find that x = 9.
If x = 9, segment BC must be 3(9) - 1 or 27 - 1 which is 26.

The least-squares regression line Sˆ=0.5+1.1L models the relationship between the listing price and the actual sales price of 12 houses, with both amounts given in hundred-thousands of dollars. Let L represent the listing price and S represent the sales price.
Answer:
For each hundred-thousand-dollar increase in the listing price, the sales price is predicted to increase by $110,000.
Step-by-step explanation:
The sales price is not predicted to increase by $1.1; it is predicted to increase by $110,000 because S is measured in hundred-thousands of dollars. The sales price will not decrease by $110,000; it is predicted to increase by $110,000.
A linear regression is represented as [tex]^\wedge y = mx + c[/tex].
The true option is: E. For each hundred-thousand-dollar increase in the listing price, the sales price is predicted to increase by $110,000.
Given that:
[tex]^\wedge S = 0.5 + 1.1L[/tex]
From the general linear equation, we have:
[tex]1.1 \to[/tex] The slope
[tex]0.5 \to[/tex] The y-intercept
The slope is the difference between the sales price of one listing and the next.
From the question, we understand that the listed amount is in 100,000's.
This means that there is an increment of [tex]\$1.1 \times 100000[/tex] between the sales price of concurrent listing
So, we have:
[tex]\$1.1 \times 100000 =\$110000[/tex]
From the list of given options (see attachment), we can then conclude that (e) is correct.
Hence, for each hundred-thousand-dollar increase in the listing price, the sales price is predicted to increase by $110,000.
