Answer:

x = 2

Step-by-step explanation:

3 3/8+4 5/7x=12 45/56

Solve :

3 3/8+4 5/7x=12 45/56

27/8 + 33/7 x = 717/56

33/7 x = (717 - 189) / 56

33/7 x = 528/56

x = 2

Wat is the slope of the line that passes through the points 3,1) and (-2,5)

den301095 [7]

Hi there!

»»————-　★　————-««

I believe your answer is:

$m=\boxed{-\frac{4}{5}}$

»»————-　★　————-««

Here’s why:

We can use the slope formula to find the slope of the two points given.

⸻⸻⸻⸻

$\boxed{\text{Recall that the slope formula is:}}\\\\\frac{y_2-y_1}{x_2-x_1}\\\\(x_1,y_1), (x_2,y_2)-\text{Points}$

⸻⸻⸻⸻

$\boxed{\text{Finding the Slope:}}\\\\\rightarrow m=\frac{5-1}{-2-3} \\\\\rightarrow m=\frac{4}{-5}\\\\\rightarrow \boxed{m= -\frac{4}{5}}$

⸻⸻⸻⸻

Sam is an artist, and he wants to purchase frames to display his work at home. He wants to frame no fewer than 10 of his pieces,

liubo4ka [24]

Answer:

The option D) $24x+18y=\dollar 225$ and $x+y^210$ is correct

Step-by-step explanation:

Given that Sam is an artist, and he wants to purchase frames to display his work at home.

He wants to frame no fewer than 10 of his pieces, and he can spend a maximum of $225. Large frames cost $24, and medium frames cost $18.

<h3>To find the system of inequalities can Sam use to determine the number of large frames, x, and medium frames, y, that he can purchase to meet his needs :</h3>

Let x be the large frames cost

Therefore $x=\dollar 24$

Let y be the medium frames cost

Therefore $y=\dollar 18$

Sam's Spend amount is $\dollar 225$

We can write the system of the given condition by

$24x+18y=\dollar 225$

$x+y^210$

<h3>Therefore the option D) $24x+18y=\dollar 225$ and $x+y^210$ is correct</h3>

Suppose you have $2,000 to invest. In 4 years, you would like to purchase a new car and want a down payment of $3,500. What inte

Blababa [14]

Answer:

Rate = 14.07%

Step-by-step explanation:

$A= P(1+\frac{r}{n})^{nt}$

A= 3500

P= 2000

n = 12

t = 4

$3500= 2000(1+\frac{r}{12})^{4 \times 12}\\\\\frac{3500}{2000} = (1+\frac{r}{12})^{48}\\\\\frac{7}{4} = (1+\frac{r}{12})^{48}\\\\1.75 = (1+\frac{r}{12})^{48}\\\\\sqrt[48]{1.75} = (1+\frac{r}{12})\\\\\sqrt[48]{1.75}-1 = \frac{r}{12}\\\\0.01172688 = \frac{r}{12}\\\\r = 0.01172688 \times 12 = 0.14072267\\\\r \% = 14.07%$

Find an equation of the line passing through the pair of points. Write the equation in the form Ax +By = C.

Alexxandr [17]

9514 1404 393

Answer:

5x -y = -37

Step-by-step explanation:

One way to find the coefficients A and B is to use the differences of the x- and y-coordinates:

A = Δy = y2 -y1 = 2 -(-3) = 5

B = -Δx = -(x2 -x1) = -(-7 -(-8)) = -1

Then the constant C can be found using either point.

5x -y = 5(-7) -2 = -37

The equation of the line is ...

5x -y = -37

<em>Additional comment</em>

This approach comes from the fact that the slope of a line is the same everywhere.

$\dfrac{y-y_1}{x-x_1}=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{\Delta y}{\Delta x}\\\\\Delta x(y-y_1)=\Delta y(x-x_1)\qquad\text{cross multiply}\\\\\Delta y(x-x_1)-\Delta x(y-y_1)=0\qquad\text{subtract y term}\\\\\Delta y(x) -\Delta x(y) = \Delta y(x_1)-\Delta x(y_1)\qquad\text{Ax+By=C form}$

The "standard form" requires that A be positive, so we chose point 1 and point 2 to make sure that was the case.
