Answer:

None of the listed answers are correct

x = 13/6

Step-by-step explanation:

13x - 7x = 13

( Note: This is not a sentence. It's an equation)

Combine like terms

6x = 13

Divide both sides by6

x = 13/6

Point C (4, 2) divides the line segment joining points A (2, -1) and B (x, y) such that AC: CB = 3.1 what are the coordinates of

IRINA_888 [86]

The coordinates of B are $(\frac{14}{3} ,3)$ .

Solution:

Given A(2, –1), B(x, y) and C(4, 2)

AB is a line segment C is a point on AB.

AC : CB = 3 : 1

To find the coordinates of B:

Section formula:

The point $P(x,y)$ divides the line segment $A(x_1,y_1)$ and $B(x_2,y_2)$ in the ratio

m : n are $\left(\frac{\mathbf{m} \mathbf{x}_{2}+\mathbf{n} \mathbf{x}_{\mathbf{1}}}{\mathbf{m}+\mathbf{n}}, \frac{\mathbf{m} \mathbf{y}_{2}+\mathbf{n} \mathbf{y}_{\mathbf{1}}}{\mathbf{m}+\mathbf{n}}\right)$

Here, $x_1=2, \ x_2=x, \ x_3=4, \ y_1=-1, \ y_2=y, \ y_3=2$ and m = 3, n = 1

Using section formula,

$$C(x_3,y_3)=\left(\frac{mx_{2}+n x_{1}}{m+n}, \frac{m y_{2}+n y_{1}}{m+n}\right)$

Substitute the given values in the section formula.

$$C(4,2)=\left(\frac{3 \times x+1 \times 2}{3+1}, \frac{3 \times y+1 \times (-1)}{3+1}\right)$

$$C(4,2)=\left(\frac{3x+2}{4}, \frac{3y-1}{4}\right)$

Equate the x-coordinates and y-coordinates.

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

$$\ 3x+2=16, \ \ \ \ 3y-1=8$

$$ 3x=14, \ \ \ \ 3y=9$

$$ x=\frac{14}{3}, \ \ \ \ y=3$

Hence the coordinates of B are $(\frac{14}{3} ,3)$ .

Which expression is equivalent to?...

stiks02 [169]

Answer:

B x^9 ∛ y

Step-by-step explanation:

(x^27 y) ^ (1/3)

x^27^(1/3) y^(1/3)

We can distribute the exponent a^b ^c = a^(b*c)

x^(27*1/3) y^(1/3)

x^9 y^(1/3)

When the subtracts 4 from both sides 1/2x=-1/2

sp2606 [1]

Subtracting 4 from both sides of the equation ¹/₂x = -¹/₂ gives us; ¹/₂x - 4 = -¹/₂ - 4

<h3>How to use subtraction property of equality?</h3>

We want to simply the expression which is;

¹/₂x = -¹/₂

Now, when we subtract 4 from both sides, it means we are using subtraction property of equality which states that subtracting the same value from both sides of an equation makes the equation still to be equal. Thus, we have;

¹/₂x - 4 = -¹/₂ - 4
