Answer:

The lines are parallel.

Step-by-step explanation:

The first line is x-y=1

In slope-intercept form, this line has equation: y=x-1

The second line is y-x=1

In slope-intercept form, the line has equation: y=x+1

The slopes of the two lines are the same (m=1)

however, the y-intercepts of these lines are different (-1) and (+1) respectively.

The first choice is correct.

The two lines are parallel and hence will never intersect.

Hello,

f^{-1}(-3)=-1\\

You have just to read the arrows un reversed order:

PLEASE HELP ME. There is 2 questions
andrey2020 [161]

Answer:

If i did the math correctly the answer to number 9 is a.5 and number 10 is c. Vanilla and German chocolate cupcakes represent about 21% of total sales

Step-by-step explanation:

for number 9 you write down each of the numbers with a dot above them. how many dots represents how many times you repeat the number. you then add it together and divide by the amount of numbers you added together. so in this case it would be 65 ÷ 12. this ends up being 5.41 but you'd round down to 5.

for number 10 you write out how many each flavor sold. then you put those numbers over the total cupcakes sold. divide the denominator by 100 and then divide the numerator by that number. then that gives you the fractions of the percent each one was. the german chocolate and the vanilla added together is almost exactly 21% of the sales

Can atriangle be formed with side lengths of 5cm. 10cm and 15cm
andreyandreev [35.5K]
Theorem of cosine:
a²=b²+c²-2bc(cos α)  ⇒cos α=-(a²-b²-c²) / 2bc

In this case:
a=15 cm
b=10 cm
c=5 cm

cos α=-(15²-10²-5²) / 2*10*5
cos α=-100 / 100
cos α=-1

A=arc cos -1=180º  This is impossible, because:

A+B+C=180º; then  B=C=0º  This is impossible for make a triangle  (B>0 and C>0 if we want to make a triangle).  

Therefore: it is not possible can make a triangle with side lengths of 5 cm, 10 cm and 15 cm.
