4x + 10= 2x - 6

Answers

Answer 1

Answer: 4x + 10= 2x - 6
Subtract 2x on both sides

4x - 2x + 10 = 2x - 2x - 6

4x - 2x + 10 = -6

2x + 10 = -6

Subtract 10 on both sides

2x + 10 - 10 = -6 - 10

2x = -6 - 10

2x = -16

x = -8

Beth filled 32 jars with paint. If each jar holds 1 pint of paint, how many gallons of paint did Beth use?

Answers

If you would like to know how many gallons of paint did Beth use, you can calculate this using the following steps:

1 jar ... 1 pint of paint
32 jars ... x pints of paint = ?

1 * x = 1 * 32
x = 32 pints of paint

1 gallon ... 8 pints
y gallons = ? ... 32 pints of paint

1 * 32 = 8 * y
32 = 8 * y /8
y = 32 / 8 = 4 gallons of paint

Result: Beth used 4 gallons of paint.

4 pints= 1 gallon
32 jars= 32 pints
32 pints/ 4 pints=8 gallons of paint

two minutes after a skydiver opens his parachute, he has descended 1,900 feet. after 5 minutes, descended 4,750 feet. if the distance varies directly with the time, at what rate is the skydiver descending?

Answers

1,900 ft/ 2 minutes= 950 ft/minute.

4,750 ft/ 5 minutes= 950 ft/minute.

If the distance varies directly with the time, the skydiver is descending at a rate of 950 feet per minute~

1900/ 2= 950

4750/5= 950
Why do you do this? Because you are trying to find the amount of ft per minute.

Write y=x^2-2x-3 in vertex form

Answers

Answer: $y=(x-1)^2-4$

Step-by-step explanation:

The vertex form of the equation of a parabola is:

$y=a(x-h)^2+k$

Where (h,k) is the vertex.

To obtain this form, we need to complete the square:

Move the 3 to the other side of the equation:

$y+3=x^2-2x$

Add this value to both sides of the equation: $((-2)/(2))^2=1$

$y+3+1=x^2-2x+1$

$y+4=x^2-2x+1$

Then, rewriting:

$y+4=(x-1)^2$

Finally, we must solve for "y", getting the equation of the parabola in vertex form:

$y=(x-1)^2-4$

To solve this, use the ‘completing the square’ strategy.
Leave a space to make the first two values a perfect square.
y=(x^2-2x___)-3
Divide -2 by 2 and square that number to put in the blank. Then subtract that number from outside.
y=(x^2-2x+1)-3-1
Simplify!
y=(x-1)^2-4
It is in vertex form now ;)
