Since the triangle is equilateral (you can tell by the tick on each side), all angles have the same measure as well.

The angles of a triangle sum up to 180 degress, so three equal angles must measure 60 degrees each.

So, in particular, we have

7x + 4 = 60 7x = 56 x = 8

Solve for x: −2x + 5 < 7 Please Help Meh!! DO you LIKE to see people STRUGGLE?!?!

x > -1

-2x+5 < 7

-2x<2

Now since you divide by (-1) to get positive 2,you need to flip the sign

(-2)/(-1)= 2 2/(-1)=-2

2x>-2

x > -1

To check the solution do not replace the x by -1 because it shouls be more than -1 (You can choose 0,1,2,3....)

Example choose x=3

-2x3+5<7

-6+5<7

-1<7

Answer:

Step-by-step explanation:

The first step to solving this equation is multiplying. Multiply the numbers on the inside of the square root.

18 × 18 × 4 = 1296

Now, you are going to find the square root of 1296.

$\sqrt{1296}$ = 36

You now have your final answer.

I hope this makes sense and is easy to understand. Please let me know if you need any more help. Have a great day! :]

Answer:

y = -3x + 7

Step-by-step explanation:

Use points on the graph:

(0, 7) and (2, 1)

Find the slope:

m = (1 - 7)/ 2 = -3

The y-intercept is known b = 7, so the equation is:

y = mx + b
y = -3x + 7
