Hi my lil bunny!

$\boxed{x = 7}$

Move 1 to the left side of the equation by subtracting it from both sides.

$\sqrt{2x -5 - 2 - 1 = 0 }$

Subtract 1 from -2.

$\sqrt{2x -5 - 3 = 0 }$

Add 3 to both sides of the equation.

$\sqrt{2x - 5 = 3}$

To remove the radical on the left side of the equation, square both sides of the equation.

$\sqrt{2x - 5^3 = 3^2}$

Simplify each side of the equation.

Multiply the exponents in $(( 2x - 5) ^\frac{1}{2})^2$ .

Apply the power rule and multiply exponents, $(a^m)^n = a^mn$

$(2x -5)^\frac{1}{2}.2 = 3^2$

Cancel the common factor of 2.

$(2x - 5)^1 = 3^2$

Simplify.

$2x - 5 = 3^2$

Raise 3 to the power of 2.

$2x - 5 = 9$

Solve for x

Move all terms not containing x to the right side of the equation.

Add 5 to both sides of the equation.

$2x = 9 + 5$

Add 9 and 5.

$2x = 14$

Divide each term by 2 and simplify.

Divide each term in 2x = 14 by 2.

$\frac{2x}{2} = \frac{14}{2}$

Cancel the common factor of 2.

$x = \frac{14}{2}$

Divide 14 by 2.

$x = 7$

Please I have the answers I just want to double check them and Solve key: B=42 A=93 N=29 X=36 1. (b-7)(2b-7) 2. (4a-4)(5a-7)

Nady [450]

1. <span>(b-7)(2b-7) = 2</span> $b^{2}$ -21b +49; b = 42 => 2* $41^{2}$ -21*42 + 49 =
3528 - 882 + 49 = 2695;

hey, do any of you guys know how to plot functions on a graph. You know like f(X) and g(X)? I find it really hard and also do yo

Tpy6a [65]

It helps if you have an example, like f(x) = 2x+3
What you typically do, is:

- draw xy axis, label them (ie., 1,2,3,4 along both axes)
- calculate the f(x) values for several x (e.g., -2, 0, 1, 3, doesn't matter).
- plot the calculated values as points. The calculated f(x) is your y value.
- sketch a smooth line through the points. It helps if you know in advance if the line is going to be straight or curved.
- The more points you calculate, the more accurate your graph will be

W + 1 = d and d = 3w solve by substitution

STALIN [3.7K]

Answer:

Step-by-step explanation:

Given

w + 1 = d...........equation 1

d = 3w ...............equation 2

Now putting d = 3w in equation 1

w + 1 = 3w

3w - w = 1

2w = 1

w = 1 / 2

putting w = 1 / 2 in equation 2

d = 1 / 2 * 3

= 3/2

Hope it helps :)

Given the points P(2,-1) and Q(-9,-6), what are the coordinates of the point on directed line segment PQ that partitions PQ in t

gayaneshka [121]

ANSWER

$( - \frac{23}{5} , - 4)$

EXPLANATION

Given the points P(2,-1) and Q(-9,-6),the coordinates of the point that partition the directed line segment PQ in the ratio 3:2 is given by

$x = \frac{ mx_2+nx_1}{m + n}$

$y= \frac{ my_2+ny_1}{m + n}$

Where m=3 and n=2

$x = \frac{ 3 ( - 9)+2(2)}{3+ 2}$

$x = \frac{ - 23}{5}$

$y= \frac{ 3( - 6)+2( - 1)}{3 + 2}$

$y= \frac{ - 20}{5} = - 4$

The point is

$( - \frac{23}{5} , - 4)$
