Which equation does the graph of the systems of equations solve?

Viktor [21]

Answer:

We conclude that option 'C' i.e. 1/3x+1=2x-4 is the correct option.

Step-by-step explanation:

From the given graph, it is clear that the two lines meet at the point (3, 2).

In other words,

at x =3, y = 2

Thus,

The point of intersection between two lines is:

(x, y) = (3, 2)

Here:

x = 3 is the value of the x-coordinate

y = 2 is the value of the y-coordinate

Now, checking the equation i.e. 1/3x+1=2x-4 to determine whether the equation contains the correct value of x-coordinate or not.

$\frac{1}{3}x+1=2x-4$

Subtract 1 from both sides

$\frac{1}{3}x+1-1=2x-4-1$

Simplify

$\frac{1}{3}x=2x-5$

subtract 2x from both sides

$\frac{1}{3}x-2x=2x-5-2x$

Simplify

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

Multiply both sides by 5

$3\left(-\frac{5}{3}x\right)=3\left(-5\right)$

Simplify

$-5x=-15$

Divide both sides by -5

$\frac{-5x}{-5}=\frac{-15}{-5}$

Simplify

$x=3$

Therefore, the value of x = 3

Conclusion:

We conclude that option 'C' i.e. 1/3x+1=2x-4 is the correct option.

Convert the mixed number 7 4/7 to a mixed decimal and round the nearest thousand

RideAnS [48]

Using a calculator, you can find out that $\sf{ \frac{4}{7}\approx 0.571428571 \approx.571$

and so that means $\sf{ 7\frac{4}{7}\approx 7.571428571 \approx 7.571$

so your answer is

$\sf{ 7\frac{4}{7} \approx \huge{\boxed{7.571}}$

100 points!!! Show your work on paper

lyudmila [28]

Answer:

10 cm, 15 cm

Step-by-step explanation:

Set ratios and solve for x

<u>Corresponding sides are AC with A'C' and CB with C'B'</u>

AC/A'C' = CB/C'B'
(x - 1)/2 = (x + 4)/3
3(x - 1) = 2(x + 4)
3x - 3 = 2x + 8
3x - 2x = 8 + 3
x = 11

<u>Find the values of AC and CB:</u>

AC = x - 1 = 11 - 1 = 10 cm
CB = x + 4 = 11 + 4 = 15 cm
