How many solutions does the following have?Y = x - 1& y - x = -9

Mathematics
1 answer:
n200080 [17]4 years ago
6 0

Answer:

No solution

Step-by-step explanation:

y=x-1 and y-x=-9

1st make sure both equations are in slope intercept form

since the 2nd equation isn't, you change it by adding x to both sides and rewrite it as y=mx+b so

y-x=-9

+× +×

y=×-9

now you have y=x-1 and y=x-9

substitute the y with the other equation

x-1=x-9

subtract x from both sides since you can't have the variable on both sides

now you've got -1 = -9

and since that equation isn't true, it has no solution.

What is the answer!!! 35.00 for a jacket. 10% discount 5% sales tax whats the final cost? PLEASE HELP ME
ASHA 777 [7]
Firstly, you should find the discount that is taken off of the jacket, and then also find the sales tax.
As the discount is 10%, you simply have to divide 35 by 10. 35/10= 3.50.
Therefore, you need to subtract the 3.50 from the 35, which gives you 31.50. You've then got the 5% sales tax to add on, which is 3.50/2= 1.75, you've then got to add 1.75 to 31.50, which gives you 33.25.
However, if the sales tax is on the discounted price, then it will be 31.50/10= 3.15/2= 1.58, and you've then got to add this is to discount price, which is 31.50+1.58= 33.08

Hope this helps :)

For the scientific notation, write the standard form: 5.61 x 102
zhenek [66]

Answer:

The standard form is 5.61 x 10^2

Step-by-step explanation:

The standard form for a scientific notation is expressed as A * 10^n

A is any value between 1 and 10

n is an integer

Given the notation 5.61 x 10^2, this is already in scientific notation since;

A = 5.61 which is between 1 and 10 and n = 2 which is a positive integer
