Answer: (-5, -5)

Step-by-step explanation:

(-4, 0)

Here, -4 is our x value and 0 is our y value

The x value moves horizontal (left and right) while the y value moves vertical (up and down)

If we move 1 unit left, we change x by -1 so, -4 -1 = -5

If we move 5 units down, we change y by -5 so, 0 -5 = -5

Therefore,

our new endpoint is: (-5, -5)

The midpoint of AB is M(-5,1). If the coordinates of A are (-4,-5), what are the coordinates of B?

Elenna [48]

ANSWER:

The midpoint of AB is M(-5,1). The coordinates of B are (-6, 7)

SOLUTION:

Given, the midpoint of AB is M(-5,1).

The coordinates of A are (-4,-5),

We need to find the coordinates of B.

We know that, mid-point formula for two points A $(x_{1}, y_{1})$ and B $(x_{1}, y_{2})$ is given by

$M\left(x_{3}, y_{3}\right)=\left(\frac{x_{1}+x_{2}}{2}, \frac{y_{1}+y_{2}}{2}\right)$

Here, in our problem, $\mathrm{x}_{3}=-5, \mathrm{y}_{3}=1, \mathrm{x}_{1}=-4 \text { and } \mathrm{y}_{1}=-5$

Now, on substituting values in midpoint formula, we get

$(-5,1)=\left(\frac{-4+x_{2}}{2}, \frac{-5+y_{2}}{2}\right)$

On comparing, with the formula,

$\frac{-4+x_{2}}{2}=-5 \text { and } \frac{-5+y_{2}}{2}=1$

$-4+\mathrm{x}_{2}=-10 \text { and }-5+\mathrm{y}_{2}=2$

$\mathrm{x}_{2}=-6 \text { and } \mathrm{y}_{2}=7$

Hence, the coordinates of b are (-6, 7).

In sugar beet, there is 21% of sugar. How much sugar beet do you need in order to get 7,413 tons of sugar?

almond37 [142]

35300 tons of sugar beet we need in order to get 7,413 tons of sugar.

Step-by-step explanation:

Given that in sugar beet, there is 21% of sugar. Need to find out how much sugar beet we need in order to get 7,413 tons of sugar. Let we need x tone of sugar beet. So, according to the asked data, we have

$21 \% \text { of } x=7413$

$\frac{21}{100} \times x=7413$

$0.21 \times x=7413$

$x=\frac{7413}{0.21}$

x = 35300 tones

Answer:

Nadia's total earnings in month is $3196.1

Explanation:

Given salary of Nadia is $3,300 per month including a 3.25% commission

The salary consists of fixed salary and commission

Therefore, Salary = Fixed salary + Commission

Assume the fixed salary to be x

Putting values in equation

3300 = x + 3.25% of x

3300 = x + $\frac{3.25}{100} x$

3300 * 100 = 103.25x

x = $\frac{3300 * 100}{103.25}$

x = $3196.1 per month

Therefore, the fixed salary of Nadia is $3196.1 per month
