The slope is -4. This is because of slope intercept form, y=mxtb. M= the slope so the slope in this case is -4

Using the slope-intercept form (y = mx + b), you can easily find the slope! In fact, y = mx + b, where m is the slope of the line, and b is the y-intercept. While not entirely necessary, we'll rewrite the equation in slope-intercept form for simplicity. To write the equation in slope-intercept form, all you need to do is isolate y.
1. y - 4x = 8 : write the equation down
2. y - 4x + 4x = 8 + 4x : Add 4x to each side of the equation so that the -4x on the left side of the equation cancels out.
3. y = 8 + 4x. Combine like terms
4. y = 4x + 8 : Rearrange the terms according to the slope-intercept form (y = mx + b)
Now that our equation is in slope-intercept form, we can easily identify the slope and the y-intercept. y = 4x + 8 If y = mx + b, where m is the slope, and b is the y-intercept, 4 must be the slope! As you get used to doing it, you can take a lot of the steps out, so this equation really only required one or two steps. However, I figured it'd be better to explain it in detail.

A spinner is split into 4 equal parts labeled 1, 2, 3, and 4.

ivolga24 [154]

Answer:

50%

Step-by-step explanation:

If there are 4 parts to the spinner, 4 is the whole. Since there are 2 even numbers (2&4), the fraction would be $\frac{2}{4}$ , which is simplified to $\frac{1}{2}$ . And because $\frac{1}{2}$ could also turn into $\frac{50}{100}$ , the percentage is 50%.

Hope this helps :)

In zoe's class, 4/5 of the students have pets. of the students who have pets, 1/8 have rodents. what fraction of the students in

olasank [31]

Let us assume the number of student's in Zoe's class = x
Then
Number of students that have pets = 4x/5
Number of students that have rodents as pets = (1/8) * (4x/5)
= x/10
Number of students in Zoe's class
that have pets that are not rodents = (4x/5) - (x/10)
= (8x - x)/10
= 7x/10
I hope that the procedure is clear enough for you to understand and this is the answer that you were looking for.

A shoe making company makes 256 pairs of boots in a day how many pairs of boots do they make in 260 days

My name is Ann [436]

Answer:

66560 pairs

Step-by-step explanation:

let the number of pairs of boots the company makes in 260 days = X

1day -----------------256pairs

260days-------------X

cross multiplying

1×X = 260×256

X= 66560

therefore, in 260days, he makes 66560 pairs

G es to prove that if a, b, and c are integers, where a ≠ 0 and c ≠ 0, such that ac | bc, then a |

Alex Ar [27]

$ac\mid bc$ means there exists an integer $n$ such that $ac=bcn$ . We can divide both sides by $c$ because $c\neq0$ . This implies $a=bn$ for some integer, which is identically $a\mid b$ .
