The equation of a line is y = mx +c

m, the slope, is -5/2

x, from the point, is 6

y, from the point is 3

equation: 3= -5/2(6) + c

3= -30/2 +c

18 = c

y = -5/2 (x) + 18

Four more than three times a number is greater than twenty-two

Delvig [45]

Answer:

3x + 4 > 22 // x = 7 or up

Step-by-step explanation:

I assume this is a 'Take words and put into an equation' so here

'Three times a number'

Lets say a number is represented by x, it'd be 3x

'Four more than'

That's addition, adding onto the previous number it would be 3x + 4

Finally the 'Greater than 22' is > this sign

3x + 4 > 22

If you need to solve for x, then whatever is multiplied by 3 then added by 4 must be more than 22. It can really be anything 7 and up. 3x5 is 15, add 4 and it's 19, which is less than 22. 3x6 is 18, add 4 and its 22, that's equal to it, not greater than. 3x7 is 21, add 4 and it's 25. Anything further along with that will be greater than 22.

What is the value of y? Enter your answer in the box. y = An isosceles triangle with vertices labeled A, B, and C. Side B C is t

klasskru [66]

Answer:

The answer is y=20

Step-by-step explanation:

If you take a look at the attached picture you will notice that angles B and C are congruent, so that means they both are 25 degrees.

Next, add angles B and C together to get 50.

Then you take that 50 and add it to 70 in angle A's equation, and you will get 120.

Next, plug 120 into angle A's equation where the 70 was and you will have the equation 3y+120=180. (180 is there because that is what all the interior angles equal together.)

Next, slove the equation.

3y+120 = 180
-120 -120
3y = 60
/3 /3
y = 20

And theres your answer, I hope I helped. Put any questions in the comments.
