74 + 35 + 16 + 45 =

= 74 + 16 + 35 + 45

= 70 + 4 + 10 + 6 + 30 + 5 + 40 + 5

= 70 + 10 + 4 + 6 + 30 + 40 + 5 + 5

= 80 + 10 + 70 + 10

= 80 + 10 + 10 + 70

= 100 + 70

= 170

The midpoint of AB is M(-4,2). If the coordinates of A are (-6,5), what are the

-Dominant- [34]

Answer:

(-2,-1)

Step-by-step explanation:

Midpoints are found when you do ([x(subscript A) + x(subscript B)]/2, [y(subscript A) + y(subscript B)]. Therefore your equation (for x of B) should look like this:

-4 = ([-6+x]/2)

After you solve for x, you should have gotten -2 for x.

Then you do the same for y:

2 = ([5+y]/2)

You should get -1. Your final answer should be (-2, -1)

Deonte invested 200000at his bank for 10 years if he earned 130000 what was the interest rate the bank gave him

Volgvan

Answer:

The interest rate the bank gave Deonte is 6.5%.

Solution:

Given, Deonte invested 200000 at his bank for 10 years

He earned 130000

We have to find what was the interest rate the bank gave him.

Now we know that, simple interest $=\frac{\text {amount} \times \text {rate} \times \text {time}}{100}$

So, by substituting our values in above formula,

$130000=\frac{200000 \times \text { rate } \times 10}{100}$

Interest rate $\times$ 20000 = 130000

Interest rate $\times$ 2 = 13

$\text { Interest rate }=\frac{13}{2}=6.5 \%$

Hence, the interest rate given by bank is 6.5% to Deonte.

Alinehasaslopeof 1/3 anda y-intercept of –5What isitsequationin slope-intercept form? Write your answer using integers, proper f

user100 [1]

Answer:

$y = \frac{1}{3}x - 5$

Step-by-step explanation:

Given

$slope\ (m) = \frac{1}{3}$

$y\ intercept = -5$

Required

Determine the line equation in slope intercept

The equation of a line in slope intercept is:

$y = mx + b$

Where

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

$b = y\ intercept = -5$

So, $y = mx + b$ becomes

$y = \frac{1}{3}x - 5$

Answer:

Option C (None Of The Above)

Step-by-step explanation:

Given expression = $- (\frac{ - e}{ - f} )$

Lets multiply the numerator and denominator by -1.

$= > - ( \frac{ - e \times - 1}{ - f \times - 1} )$

$= > - ( \frac{e}{f} )$

Now , lets open the brackets.

$= > \frac{ - e}{f}$

But as this expression is not there in the given options , the correct answer will be Option C.
