Answer:

x = 3

Step-by-step explanation:

given

4(x - 8) + 10 = - 10 ← subtract 10 from both sides

4(x - 8) = - 20 ← divide both sides by 4

x - 8 = - 5 ← add 8 to both sides

x = 3

<h2>Answer:</h2>

<u>The answer is </u><u>x = 3</u>

<h2>Step-by-step explanation:</h2>

Let's solve your equation step-by-step.

4(x−8)+10=−10

Simplify both sides of the equation.

4(x−8)+10=−10

(4)(x)+(4)(−8)+10=−10(Distribute)

4x+−32+10=−10

(4x)+(−32+10)=−10(Combine Like Terms)

4x+−22=−10

4x−22=−10

Add 22 to both sides.

4x−22+22=−10+22

4x=12

Divide both sides by 4.

4x/3 = 12/3

x=3

3. Sqrt of 40

4. Sqrt of 148

Distance formula is sqrt of (x-x1)^2+(y-y1)^2

So (-4-2)^2+ (3-5)^2

(-6)^2+(-2)^2

36+4

Sqrt of 40

Do the same process for 4!

Ps don’t forget to keep the square root

A golfer hits a ball from a starting elevation of 2 feet with a velocity of 70 feet per second down to a green with an elevation

ikadub [295]

Answer:

4.50 s

Step-by-step explanation:

The motion of the ball is represented by the following equation:

$h(t) = 2+70t-16t^2$ (1)

where

h(t) is the elevation at time t

2 ft is the initial elevation at t = 0

+70 ft/s is the initial vertical velocity

$-32 ft/s^2$ is the acceleration due to gravity

The green is located at an elevation of -7 feet, so the ball lands on the green when

h(t) = -7

Substituting into (1)

$-7=2+70t-16t^2$

And re-arranging we get

$16t^2-70t-9=0$

This is a second-order equation in the form

$at^2+bt+c=0$

which has solutions

$t_{1,2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$ (2)

Here we have:

a = 16

b = -70

c = -9

Substituting into (2) we find the solutions:

$t_{1,2}=\frac{70\pm \sqrt{(-70)^2-4(16)(-9)}}{2(16)}$

The two solutions are:

t = 4.50 s

t = -0.125 s

The second solution is negative, and since negative time has no physical meaning, the only correct solution is

t = 4.50 s
