It’s only 0 because x=16. If you plug in 16 as x, the first part of the equation is -4. If you try using 0, 1, 10, x, or -x for the next part (also using 16 as x) then only 0 will give you -4

A line that includes the point (16, 15) has a slope of 0. What is its equation in
slope-intercept form?

Answers

9514 1404 393

Answer:

y = 0x + 15

Step-by-step explanation:

A line with a slope of 0 is a horizontal line. It has the same y-value everywhere. If it goes through the point (16, 15) with y-coordinate 15, then its y-intercept is 15.

Writing the slope explicitly, the equation is ...

y = 0x +15

Simplified, the equation is

y = 15

Answers

Answer:

8,100

Step-by-step explanation:

7,200 - 6,400 = 800 increased in 50. Years

What percentage is 800 of 6,400 (%/100 = is/of)

x/100 = 800/6400 (cross multiply)

(800*100)/6400 = 12.50%

(12.50 * 7200)/100 = 900 increased

7,200 + 900 = 8,100

not 100% sure since you didnt show us an image

we change this number 1.5=15/10=3/1 and 0.5=5/10=1/2

it will show on the number line!

The expression using subtraction to find the distance between the two jellyfish is 0.5 - (-1.5).

The distance between the two Jellyfish is 2.

We have,

The point of A on the number line: -1.5

The point of B on the number line: 0.5

Now,

To find the distance between the two jellyfish.

= B - A

= 0.5 - (-1.5)

= 0.5 + 1.5

= 2

Thus,

The expression using subtraction to find the distance between the two jellyfish is 0.5 - (-1.5).

The distance between the two Jellyfish is 2.
