If the slope of a line is 1/2 and the y-intercept is 6, what is the x-intercept of the same line?
ASHA 777 [7]

The slope of a line is the ratio of the change in y to the change in x. The slope of the given line is 1/2 = -6/-12. That is, when y changes by -6 to go from 6 to zero, x will change by -12 to go from 0 to -12.

The x-intercept is (-12, 0).

If I spend 3/4 of the
podryga [215]

Answer:

1/8 of the original sum still remains.

Step-by-step explanation:

If you spend 3/4 of what you have, you have 1/4 left.

Now you spend 1/2 of that 1/4, so basically divide 1/4 by 2. When dividing fractions you can multiply the fraction by the reciprocal of the other fraction.

\frac{1}{4} ÷ \frac{2}{1} = \frac{1}{4} * \frac{1}{2}

= 1/8

So I think 1/8 of the original sum still remains.

Hope this helped, please mark brainliest if possible. Have a nice day.

Nick was surveying his field and saw some cows and ducks. Nick counted a total of 80 heads and
Tcecarenko [31]

Answer:

<u>44 cows and 36 ducks.</u>

Step-by-step explanation:

x is ducks and y is cows.

Assuming both have 1 head each, we can write:

x + y = 80.

Let's assume each x(cow) has 4 legs and each y(duck) has two legs.

Then we can add the numbers of legs:

2x + 4y = 248 legs

Now rearrange x + y = 80 to:

x = 80-y

and substitute:

2x + 4y = 248 legs

2(80-y) + 4y = 248 legs

160 - 2y + 4y = 248 legs

2y = 88 legs

<u>y = 44   [There are 44 cows]</u>

Use this value to find the number of ducks:

x + y = 80

44 + y = 80

<u>y = 36  [There are 36 ducks]</u>

========================

Check:

Do 44 cows and 36 ducks have a total of 248 legs?

4*44 + 2*36 = 248 ?

176 + 72 = 248?

<u>YES</u>
