~7)~
$(3×4×5)
=1.585 + 2 + 2.322
=5.907$
~8)
$(3÷2÷5)
=1.585 - 1 - 2.322
=-1.737$
9) $3log7(2) -2log7(3) + 4log7(3) -2log7(2)
=0.356+2(0.565)
=1.486$
9) $x(x+2)=8
x=2$
10) $x/(2x+3)=1/9
9x=2x+3
x=3/7$

Hope this helps

Point m is the midpoint of kL. M(1,-1) and L(8,-7. What are the coordinates of point k?

Phoenix [80]

Answer: (-6, 5)

<u>Step-by-step explanation:</u>

Use the Midpoint Formula: $\dfrac{(x_k, y_k)+(x_L,y_L)}{2}=(x_m, y_m)$

Separate the x's and y's and solve them individually:

$\dfrac{x_k+x_L}{2}=x_m\qquad \qquad \qquad \qquad\dfrac{y_k+y_L}{2}=y_m\\\\\\\dfrac{x_k+8}{2}=1\qquad \qquad \qquad \qquad \qquad \dfrac{y_k-7}{2}=-1\\\\\\x_k+8=2\qquad \qquad \qquad \qquad \qquad y_k-7=-2\\\\\\x_k\quad =-6 \qquad \qquad \qquad \qquad \qquad y_k\qquad =5$

So, the k-coordinate is (-6, 5)

Answer:

6.8

Step-by-step explanation:

Similar means the same shape but smaller. So we have to find the connection between 17 and 5. Which can be achieved by this equation

17/5=3.4

Now we apply the number 3.4 to find the length of PQ using the same side on the similar shape

2*3.4=6.8

Hope this helps and I’m sorry to ask but I would love a Brainliest

Venus Waldo reviewed her account statement and wanted to verify that the interest amount was correct. Her new balance was $12,09

user100 [1]

Answer:

The interest on the savings account is $46.47

Step-by-step explanation:

Here, we want to know the interest earned on the savings account.

The difference between the new and previous balance will be; 12,098.12 - 9,053.20 = $3,044.92

The difference between amount deposited and amount withdrawn is 3,298.45 - 300 = 2,998.45

This is the amount that is supposed to be on the account without interest

So the interest earned would be; 3044.92 - 2,998.45 = $46.47
