2x² + 5x - 42 = 0 * PLEASE SHOW YOUR WORK *

Answers

Answer:

x = - 6, x² = [tex]\frac{7}{2}[/tex]

Step-by-step explanation:

[tex]2x^{2}[/tex] + 12x - 7x - 42 = 0

2x^{2} (x + 6) - 7 (x + 6) = 0

(x + 6) x (2x - 7) = 0

x + 6 = 0

2x - 7 = 0

x = - 6

x = [tex]\frac{7}{2}[/tex]

x = - 6, x² = [tex]\frac{7}{2}[/tex]

A person can walk 3 1/4 miles in one hour. How many miles can the person walk in 1 3/4 hours?

Answers

Since Emily is walking at a constant speed, we can solve this using proportions, equating ratios of distance/time.

The first ratio is 3/4 miles/1/4 hour
The second ratio is 1 mile/ x hour

Equating the two ratios: 3/4 / 1/4 = 1/x
3 = 1/x
x = 1/3 hour

which equation is perpendicular to y= -2x + 5 ?

A) y= -2x -5
B) y= 2x -3
C) y= 1/2x -2
D) y=-1/2x+1

Answers

Ok so in order for the equation to be perpendicular, the slope have to be opposite of each other.

The original equation had -2 as the slope. The opposite of -2 is 1/2.

When the number is negative, the opposite of it is positive.
And in order for them to be completely opposite, you have to flip the number. So 2 turned into 1/2, since the denominator of 2 is 1.

And so since the opposite slope is 1/2, C is the correct answer.

6+n/5=9

What is happening to the variable?

How do you solve for the variable?

Answers

Answer:

n=15

Step-by-step explanation:

(subtract 6 from both sides of the equation.)

6+n/5=9

6+n/5-6=9-6

(Now you will have to simplify.)

n/5=3

(You will have to multiply all terms by the same value to eliminate fraction denominators.)

n/5=3

5xn/5=5x3

(You will now have to simplify.)

n=15

And that's how you get your answer.

i hope this helps. :)

Answers

Answer:

y = 8; x = 6 [tex]\frac{7}{8}[/tex] ; n = 1 [tex]\frac{2}{23}[/tex] ; p = 55

Step-by-step explanation:

First proportion

// How to solve it

// firstly, multiply both sides by y, so that y would be in numerator

[tex]\frac{16}{16} * y[/tex] = [tex]\frac{8}{y} * y[/tex]

// now we get

[tex]\frac{16y}{16}[/tex] = 8

// secondly, divide both sides by [tex]\frac{16}{16}[/tex], so that we'd have y on one side and the expression on the other side

y = [tex]\frac{16}{16}*8[/tex]

// since [tex]\frac{16}{16}[/tex] = 1

y = 8

Second proportion

// divide both sides by 22, so that there'd be unknown variable x on one side and the expression on the other side

x = [tex]\frac{10*22}{(y*4)}[/tex]

Is this y from the first proportion?

If so, then x = [tex]\frac{10*22}{(8*4)}[/tex] = [tex]\frac{220}{32}[/tex] = [tex]\frac{55}{8}[/tex] = 6 [tex]\frac{7}{8}[/tex]

Third proportion

// divide both sides by 5

n = [tex]\frac{5}{23} * 5[/tex] = [tex]\frac{25}{23}[/tex] = 1 [tex]\frac{2}{23}[/tex]

Fourth proportion

// divide both sides by 10

p = [tex]\frac{22}{4} *10[/tex] = 55
