Answer: y= x +3

1) find slope using rise over run. Find your coordinates. I used (-3,0) and (0,3). Rise over run with these values : 3-0/0- -3. You should get 1 as a slope after adding and simplifying. Y=1x+b is your equation. Plug in your y and x values to the equation: 3= 0x1 +b. Multiply: 3= 0+b. B is 3( your y intercept). The equation is y=x+3

The perimeter cannot be same but the Equation can be 4x+ 4= 4x+ 8.

what is Perimeter?

The complete length of a shape's boundary is referred to as the perimeter in geometry. A shape's perimeter is calculated by adding the lengths of all of its sides and edges. Its dimensions are expressed in linear units like centimetres, metres, inches, and feet.

Given:

For Square:

We have side= x+ 1

Now, Perimeter of Square = 4 x side

                                            = 4(x+ 1)

                                            = 4x+ 4

For Rectangle:

We have length= x+ 4 and width= x

Now, Perimeter of Square = 2 ( l+ w)

                                            = 2( x+ x+ 4)

                                            = 4x+ 8

So, the perimeter cannot be same but the Equation can be 4x+ 4= 4x+ 8.

Create a proportion using the form = to represent the following word problem.

78% of what number is 42?

Answers

Answer :
x = 53.85

Step by step explanation:
If 78% of x (some numbers) is equal to 42, then we must set this as an equation to find it.

1) Rewriting 78% as a fraction and considering that when we say 78% of some number (x) we mean a product.
78% = 78/100 ➡️ 78/100x = 42

2) Then we can go on :
100 * 78/100x = 42 * 100
78x = 4200
78x/78 = 4200/78 ➡️ x = 53.85

3) Alternatively, simply dividing 42 by 0.78 (78%) would come to the same result :

42/0.78 = 53.85
To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 42 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 42 is 100%, so we can write it down as 42=100%.
4. We know, that x is 78% of the output value, so we can write it down as x=78%.
5. Now we have two simple equations:
1) 42=100%
2) x=78%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
42/x=100%/78%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 78% of 42

42/x=100/78
(42/x)*x=(100/78)*x - we multiply both sides of the equation by x
42=1.28205128205*x - we divide both sides of the equation by (1.28205128205) to get x
42/1.28205128205=x
32.76=x
x=32.76

Which inequality describes all the solutions to -3(4 – x) + 6 < 9 – 2x?

Answers

Answer:

To do inequalities, you just need to solve the equality and then figure out what side (higher or lower) the solution is on and put in the appropriate greater-than, less-than, greater-than-or-equal-to or less-than-or-equal-to sign.

 

Think about the equality for this one. What equation could we right for the average number of words per week that would put Trevor right at 50,000 after 5 weeks.

 

If we call the number of words per week, w, we would have

 

w = [an expression]   (You find the expression using the number of words he has to write and how many weeks he has.)

 

Now think about the inequality. Trevor wants to finish in five weeks or less. So as long as he writes at least this number of words per week, he'll make it. That means we want a greater-than-or-equal to sign:

 

w ≥ [your expression]

Step-by-step explanation:

The inequality which describes all the solutions to the inequality is

x < 3

Given the inequality expression given as -3(4 – x) + 6 < 9 – 2x, we need to find the solution to the system of inequality as shown:

[tex]-3(4 -x) + 6 < 9 - 2x[/tex]

Expand the bracket

[tex]-3(4 -x) + 6 < 9 - 2x\\-12+3x+6<9-2x\\3x-6<9-2x\\3x+2x<9+6\\5x<15\\x<15/5\\x<3[/tex]

Hence the inequality which describes all the solutions to the inequality is

x < 3

A store sells a hoodie for $45, the sales tax rate in this state is 8%. What is the total price with sales tax applied?

Answers

The answer is $48.60.

The hoodie by itself has a price of $45. If the sales tax if 8% of the price you’d have to calculate the sales tax and add it to the net amount.

(45)(.08) = 3.60

(45) + 3.60 = 48.60
$48.60. multiply 45 by 0.08 to find the tax, which is $3.60. add the price plus the tax and you have the end price, which is $48.60
