Solve the system of equations: y= 2x+1 y = x2 + 2x-8

Mathematics
1 answer:
KatRina [158]3 years ago
6 0

Answer:

x = ±3

Step-by-step explanation:

Put both equations equal to each other.

2x + 1 = x^2 - 8

Cancel 2x on both sides.

1 = x^2 - 8

Add 8 to both sides.

1 + 8 = x^2

Simplify 1 + 8 to 9.

9 = x^2

Take the square root of both sides.

±√9​​ = x

±3=x

Simplify.

x = ±3

!!!The volume of a cylinder is 675π cm3. The radius of the base of the cylinder is 5 cm. What is the height of the​ cylinder?
kompoz [17]

Answer:

The answer is

<h2>27 cm</h2>

Step-by-step explanation:

Volume of a cylinder is given by

<h3>V = πr²h</h3>

where

h is the height

r is the radius

V is the volume

Since we are finding the height

h =  \frac{V}{\pi  {r}^{2} }

From the question

V = 675π cm³

r = 5 cm

Substitute the values into the formula and solve for the height

That's

h =  \frac{675\pi}{ {5}^{2}\pi }  \\  =  \frac{675\pi}{25\pi}  \\  =  \frac{675}{25}

We have the final answer as

27 cm

Hope this helps you

vaieri [72.5K]

Answer:

Part A:24140 PartB: 16865

Step-by-step explanation:

multiply the total number of people by the decimal form of the percentage (move decimal left two places)

71000*.34=24140

71000*.425=30175

then to find the other number you must add the two before then subtract from the total

24140+30175=54135

71000-54135=16865
