Answer:

3.5 = y

Step-by-step explanation:

2.5y + 6 = 4.5y - 1

2.5y + 7 = 4.5y

7 = 2y

3.5 = y

Check:

2.5y + 6 = 4.5y - 1

2.5(3.5) + 6 = 4.5(3.5) - 1

2.5(3.5) + 7 = 4.5(3.5)

8.75 + 7 = 15.75

15.75 = 15.75

Answer:

[tex]y=3.5[/tex]

Step-by-step explanation:

[tex]2.5y+6=4.5y-1[/tex]

Start by subtracting [tex]6[/tex] from both sides of the equation:

[tex]2.5y=4.5y-7[/tex]

Subtract [tex]4.5y[/tex] from both sides of the equation:

[tex]-2y=-7[/tex]

Divide both sides of the equation by the coefficient of [tex]y[/tex], which is [tex]-2[/tex]:

[tex]y=3.5[/tex]

_

Check your solution by substituting the solved value of [tex]y[/tex] ([tex]3.5[/tex]) into the initial equation:

[tex]2.5(3.5)+6=4.5(3.5)-1[/tex]

[tex]8.75+6=15.75-1[/tex]

[tex]14.75=14.75[/tex]

Since both sides of the equation are equal to each other, our solution is correct!

Answer:

Im pretty sure slope is 21 and y intercept is 15

The slope is 21 and the y-intercept is -33 of the graph of function h.

A linear function is defined as a function in the form of f(x) = mx + c where 'm' and 'c' are real numbers.

It represents the line's slope-intercept form, which is written as y = mx+ c.

The function is given in the question below as

f(x) = –7x + 9

⇒ f(x) = –7x + 9

Add 2 to the input of f to create a new function g,

⇒ g(x) = –7x + 9 + 2

⇒ g(x) = –7x + 11

Now, multiply the output of function g by –3 to create function h.

⇒ h(x) = (–7x + 11) × -3

⇒ h(x) = 21x - 33

Compare to the line's slope-intercept form,

Therefore, slope = 21 and y-intercept = -33

Step-by-step explanation:

substitute 0 for y

The value of the function h(x) at x equal to 4 is -2.

A function is defined as the expression that set up the relationship between the dependent variable and independent variable. Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Given function is  h(x) = -x + 2, the value of the function at x equal to 4 will be calculated as below:-

h(x) = -x + 2,

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

h(x) = -2

Therefore, the value of the function h(x) at x equal to 4 is -2.

Answer:

number is 5

Step-by-step explanation:

The reciprocal of a number n is [tex]\frac{1}{n}[/tex] , thus

n - [tex]\frac{1}{n}[/tex] = [tex]\frac{24}{5}[/tex]

Multiply through by 5n to clear the fractions

5n² - 5 = 24n ( subtract 24n from both sides )

5n² - 24n - 5 = 0 ← in standard form

(n - 5)(5n + 1) = 0 ← in factored form

Equate each factor to zero and solve for n

n - 5 = 0 ⇒ n = 5

5n + 1 = 0 ⇒ 5n = - 1 ⇒ n = - [tex]\frac{1}{5}[/tex]

However, n > 1 , thus n = 5

That is the number is 5

Answer:

Step-by-step explanation:

So, Vicki wants no left overs whatsoever, which means we have to get all three items to the same number. We first look at 10. We know that 10 will always have a 0 in the one's place, meaning that 8 and 12 have to be multiplied by 5, 10, 15, 20, etc., but they do not need to be multiplied by the same number.

Let's take 8 first. 8 can possibly go up to 40, 80, 120, 160, 200, etc.

Then 12. 12 can possibly go up to 60, 120, 180, 220, 280, etc.

We can see that both numbers have 120 in common, so we shall use that.

We know that we can get 10 to 120 by multiplying 10 by 12, meaning Vicki buys 12 packs of cups.

We know that we can get 12 to 120 by multiplying 12 by 10, meaning Vicki buys 10 packs of plates.

And finally, we know that we can get 8 to 120 by multiplying 8 by 15, meaning Vicki buys 15 packs of utensils.

So, since the question is asking for utensils only, we should say that Vicki buys 15 packs of utensils.

1-3/0--1 = -2/1 = -2

The slope is -2

y=-2x+b

1 = -2(0)+b

1 = b

The y-intercept is 1

The equation is

First, we want to find the slope. To do this we use the equation y2-y1 / x2-x1. For the problem, we use the points (-1,3) and (0,1). This would look like: 3-0/1--1. This would simplify to 3/2. To find the y-intercept, find the point (0, y). In this problem, that point would be (0,1). Now you can plug this into y = mx+b. Therefore, your equation is y = 3/2x + 1.

Answer:

72773100000%

Step-by-step explanation:

"Percent" means "per 100" or "over 100". So, to convert 727731000 to percent we rewrite 727731000 in terms of "per 100" or over 100.

Multiply 727731000 by 100/100. Since 100/100 = 1, we are only multiplying by 1 and not changing the value of our number.

7277310001×100100=72773100000100

72773100000/100 is 72773100000 over 100 and means 72773100000 per 100. 72773100000 "per 100" means 72773100000 "percent" or 72773100000%

Therefore, we have shown that

727731000 = 72773100000%

Simplified Conversion:

Multiply by 100 and add the percent sign %

727731000 × 100 becomes 72773100000%

Shortcut Conversion:

Move the decimal point 2 places to the right and add the percent sign %

727731000 becomes 72773100000%
