Answer:  y=5

Step-by-step explanation:

The line only has a value of 5, regardless of the value of x.  So the slope of this line is "o," the vlaue of x has no influence on the value of y.

y = mx + b

y = ox + b

b is the y-intercept, the value of y when x = 0.  That would be 5, again:

y = 0x + b

y = b

y = 5

It it’s y=5

Explanation:
Because on a linear graph the equation is y=x so with this specific graph the line goes horizontally on (5,0) so applying that to the equation its y=5

Answer:

 (B)  4

Step-by-step explanation:

Consider the units column. The only sum of 3 and a single digit that will end in 1 is the sum ...

  3 + 8 = 11

This tells you A = 8, so the top number is 1983, and the middle number is B78.

Considering the first two columns, we know that 83 +78 = 161, so there must be a carry of 1 into the third column. That makes it have the sum ...

  1 + 9 + B = <something ending in 4>

We know the something cannot be 04 or 24, so must be 14. Then ...

  10 + B = 14   ⇒   B = 4

__

So, the whole sum is ...

  1983 +478 = 2461

and the letter values are ...

A = 8B = 4D = 2

Answer:

B is 4.

Step-by-step explanation:

If we start by the ones place and add we know that to get a one the total must be 11. 11-3 = 8.  Therefore A = 8.

Now we move to the tens place, since we know A is 8 we can substitute it there.  Don't forget to add the one from the 11 we got. 1+8+7 = 16

Now we move to the hundreds place and we carry our one from 16 so now it's 1 + 9 + ? = 4, if we know that our total needs to be 14 in order to have the 4 there- 1 + 9 is 10 we can do 10 + 4 and that gets us 14. So B is 4.

I will name you brainless if you give correct answer

Answers

Answer:

Other side = 60

Perimeter = 150

Step-by-step explanation:

Using Hypothenuse formula

25²+B²=65²

625+B²=4225

B²=4225-425

B²=3600 (Bring Square to the other side to become Square root)

B=√(3600)

B=60

Perimeter:(Sum of all side)

Write the equation of the line in fully simplified slope-intercept form.

Answers

First find your slope. Staring at the point at (-6,3), you’d go “down 5, right 6” to get to the point at (0,-2). That’s your slope: -5/6

Next find your b-value, your y-intercept: (0,-2). For the slope-intercept form, you only need the -2 as your b-value.

Putting that together into slope-intercept form, y=mx+b, you’d have an equation of y = -5/6 x - 2.

A small submarine starts at –1,260 feet in relation to sea level. Then it descends 5 feet per minute for 12 minutes.

What integer represents the rate of motion of the submarine?

–
feet per minute

Answers

Okay so our starting point is - 1,260 feet

Now it is descending (-) 5 ft per minute for 12 minutes

So we multiply -5 (negative because it is descending) by 12

-5 x 12 = -60

So now we add -60 to -1,260

This would be -1,320

So the submarine's new position in relation to the sea level is -1,320

Hope this helped. Have a great day!

that would be -1260 + 12(-5) = -1260 - 60 = -1320 feet
