Step-by-step explanation:

Answer:

x=6

Step-by-step explanation:

We simplify the equation to the form, which is simple to understand

x/32=3/16

Simplifying:

+ 0.03125x=3/16

Simplifying:

+ 0.03125x=0.1875

We move all terms containing x to the left and all other terms to the right.

+ 0.03125x=0.1875

We simplify left and right side of the equation.

+ 0.03125x=0.1875

We divide both sides of the equation by 0.03125 to get x

The correct option is D f⁻¹(x) = 2 + √(x + 2).

A function is defined as the expression that set up the relationship between the dependent variable and independent variable.

The inverse function of a function f in mathematics is a function that reverses the operation of f.

The given function is f(x) = 1 / (2 + √(x + 2)). The inverse function of the given function is,

f⁻¹(x) = 2 + √( x + 2).

$32 for each hockey stick

Step-by-step explanation:

71+25=96

Zack received $32 for each hockey stick he sold. He earned $96 in total from selling 3 sticks after deducting $25 for gloves, leaving him with $71.

Given that Zack sold 3 old hockey sticks and earned a total amount of money.

He spent $25 of his earnings on a pair of used hockey gloves.

After buying the gloves, he had $71 remaining.

Now, we need to find out how much Zack received for each hockey stick.

Let's assume the amount he received for each hockey stick is "x" dollars.

Total earnings from selling the hockey sticks = Number of sticks sold × Amount received per stick

Total earnings = 3x

Zack spent $25 on gloves and had $71 remaining, so we can write this equation:

Total earnings - Amount spent = Remaining money

3x - 25 = 71

Now we can solve for x (the amount received for each hockey stick):

3x - 25 = 71

Add $25 to both sides:

3x = 96

Divide both sides by 3:

x = $32

So, Zack received $32 for each hockey stick he sold.

we can do this simply by

(y2-y1)/(x2-x1)

and simplifying

Cost price:-

[tex]\\ \sf\longmapsto 35\times 20[/tex]

[tex]\\ \sf\longmapsto 700[/tex]

Now

Return=823-700=123

Rate of return

[tex]\\ \sf\longmapsto \dfrac{123}{700}\times 100[/tex]

[tex]\\ \sf\longmapsto \dfrac{123}{7}[/tex]

[tex]\\ \sf\longmapsto 17.5\%[/tex]

The rate of return on the stock will be equal to 17.3%.

The Latin phrase "per centum," which means "by the hundred," is where the English word "percentage" comes from. Percentage segments are those with a numerator of 100. In other words, it is a connection where the whole is always deemed to be valued 100.

As per the given information in the question,

Total number of stocks = 35

Purchase price of each stock = $20

Then, the price of 35 stocks will be,

35 × $20 = $700

The selling price of all stocks = $815

Also, the commission for selling is $6.

So, the extra money earned will be,

815 - 700 + 6 = 115 + 6

= $121

So, the rate of return from the original price will be,

= 121/700 × 100

= 12100/700

= 17.3%

Answer:

One solution

Step-by-step explanation:

3x+x+2=8x-4x+2

Combine like terms.

4x+2=4x+2

Solve for x

4x+(-4x)+2=4x+(-4x)+2

2=2

This equation has one solution because 2 only equals 2 and will not equal any other number.

Considering the situation given, it is found that:

Answer:

1.   y = 7x + 2

2.   y = 1/3x - 1  or 3y = x - 3

Step-by-step explanation:

Use this formula y = mx + b   where the slope is represent by "m" and the y-intercept is represent by "b"

1.    y = mx + b

     y = 7x + 2

2.   y = mx + b

     y = 1/3 x + (-1)      Let clean this up by multiplying each term by 3

     3y =  1x - 3  or 3y = x - 3

Answer:

a. For every +1 input in x, y goes up 4 times plus 7.

b. y= 4x+7

c. 35

d. 6

Step-by-step explanation:

How to do c.

y=4x+7

y=4(7)+7

y=35

How to do d.

y=4x+7

31=4x+7

24=4x

x=6

We can solve for t by making it the subject of the equation.
