|2x+3|+9=20. please help. add explanation

Rashid [163]

Answer:

The solution of this equation is 'x = 4'.

Step-by-step explanation:

|2x + 3| + 9 = 20
=> 2x + 3 + 9 = 20
=> 2x + 12 = 20
=> 2x = 20 - 12
=> 2x = 8
=> x = 4

Hence, the solution of this equation is 'x = 4'.

You are given that a wheel has a radius of 2 feet and a spin rate of 10 revolutions per minute. Describe how you would determine

ss7ja [257]

Answer:

About 126 ft/min

Step-by-step explanation:

We know r = 2 feet, and that the wheel has an angular speed of 10 rpms, or 10 revolutions per minute. Our goal is to get the speed in ft/sec.

10 rev 1 minute 2π radians 2 feet

----------- × ---------------- × ------------------ × ------------

1 minute 60 seconds 1 revolution 1 radian

= 10 * 2π * 2 = 126 ft/minute

The answer is reasonable. Another, simple approach to this would be using the formula 2π * r * rpm. If so, 2π * 2 * 10 which would be 126 ft/minute.

What is an equation of the line that passes through the points (7,−6) and (3,−6)?

alexandr1967 [171]

Answer:

The equation of this line would be y = -6

Step-by-step explanation:

In order to find this, we must first find the slope. For that we use the two points and the slope equation.

m(slope) = (y2 - y1)/(x2 - x1)

m = (-6 - -6)/(7 - 3)

m = 0/4

m = 0

Given that slope, we can use it along with a point in point slope form. From there we can solve for y and get the equation.

y - y1 = m(x - x1)

y + 6 = 0(x - 7)

y + 6 = 0

y = -6
