Answer:

x = 5

Step-by-step explanation:

Given

4x - 3 = 2x + 7 ( subtract 2x from both sides )

2x - 3 = 7 ( add 3 to both sides )

2x = 10 ( divide both sides by 2 )

x = 5

Answer:

x=5

Step-by-step explanation:

you will start by subtracting 2x from 4x then you are left with 2x-3=7. then you will add 3 to 7 that will give you 2x=10, then divide 2 from 10. from there you get x=5.

Which equation shows the point slope form of the line that passes through (5,1) and has a slope of 1/2

arsen [322]

Answer:

3rd option, $y-1 = \frac{1}{2} (x-5)$

Step-by-step explanation:

To find out which option is correct, we can write the equation in point-slope form ourselves.

Use the point-slope formula $y-y_1 = m (x-x_1)$ to write the equation in point-slope form. Substitute the $m$ , $x_1$ , and $y_1$ for real values.

Since $m$ represents the slope, substitute $\frac{1}{2}$ in its place. Since $x_1$ and $y_1$ represent the x and y values of a point the line intersects, substitute the x and y values of (5,1) into the formula as well. Substitute 5 for $x_1$ and 1 for $y_1$ . This gives the following equation:

$y-1 = \frac{1}{2} (x-5)$

9 + |-78| - (-22) Answer truthfully please.

GuDViN [60]

Answer:

109

Step-by-step explanation:

9 + |-78| - (-22)

Apply the absolute value which states |-x| = x.

9 + 78 - (-22)

Apply the rule that states x - (-y) = x + y.

9 + 78 + 22

Add 9 and 78.

87 + 22

Add 87 and 22.

109.

Sara goes on a slingshot ride in an amusement park. She is strapped into a spherical ball that has a radius of 3·10^2 centimeter

kondaur [170]

To solve for the volume of a spherical ball, we use the formula,

V = (4πr^3)/3

The given radius of 3x10^2 centimeters converts to 3 meters. Solving for the volume,

V = (4π)x(3^3)/3 = 36π m^3

Thus, Sara is trapped in a spherical ball with a volume of 36π m^3.
