PLEASE ANSWER ASAP! The function f(x) is graphed on the - 1

Answer 1
Answer:

Answer:

f(-1) = 3

Step-by-step explanation:

See the graph shown in the attached file with the given question.

The graph passes through (0.5,0) point on the X-axis and (0,1) point on the Y-axis.

So, the length of the X-intercept is 0.5 and that of Y-intercept is 1.

Hence, the equation of the straight line graph is  

(x)/(0.5) +(y)/(1) =1{Using the intercept form}

⇒ 2x + y = 1 ....... (1)  

Now, y = f(x) = 1 - 2x

Hence, f(-1) = 1 - 2 ( - 1 ) = 3 (Answer)

How to solve question 22?

Answers

Answer:

Josh has 29 coins.

Step-by-step explanation:

Let Terry have x coins then Josh has x + 12 coins.

Together they have x + x + 12 coins so we can form the equation:

x + x + 12 = 46

2x + 12 = 46

2x = 46 - 12 = 34

x = 17, so Terry has 17 coins and Josh has 17 + 12 = 29 coins.
Answer - C - 29
That is , Josh has 29 coins.

Give a counter example to this statement. The quotient of two fractions between 0 and 1 is always a whole number.

Answers

0< (1)/(6) <1 \n 0< (1)/(3) <1 \n ( (1)/(6) )/( (1)/(3) ) = (3)/(6) = (1)/(2)
There are many counter examples to this. People seem to think multiplying two fractions will get you a whole number but it definitely isn't the case. Just take 1/2 and 2/3 as an example:

1/2 ÷ 2/3 (dividing is the same as multiplying by the reciprocal)

1/2 * 3/2 is 3/4 and that is not a whole number. Hope this helped.

11x=891
(11x)/(11)=(891)/(11)
x=81

There are eighty-one marbles.
Radio:11:9\n 11--99\n \ 9--x\n x=(9)/(11)*99=81

Find the coordinates of an image of point R(3, -5) rotated 180 degrees about the origin.

Answers

if it was rotated 180, then the  siigns are switched becasue 180 is 1/2 of 360, so the signs are switched and you get (-3,5)

this was kind of easy so maybe I am wrong.
When you rotate a coordinate pair by 180 degrees you simply multiply the x and the y by a negative 1

so 3 x -1 and -5 x -1 will give you a new coordinate pair of (-3, 5)

hope this helps
