Answer:

x=14 and y=7

Step-by-step explanation:

This is a 30-60-90 triangle

So in terms of x it would be $x-x\sqrt{3} -2x$

If across the 60 is $7\sqrt{3}$ then y would be 7 which is across the 30 degrees

And x would be 14 because 2(7)=14

1. 3/4
2. 3/4
3. 3 whole parts one missing part
4. 0.75 75% 6/8
5. It’s closer to 1 on a number line because it’s more then 1/2
6. A fraction greater could be 7/8 Bc it’s more then 6/8 and 6/8 is equal to 3/4
A fraction less then could be 1/4 Bc 1 is less then 3

Answer:

63.7 inches

Step-by-step explanation:

half the base is 9 inches, so the equal legs are each

L = √(9² +21²) = 22.8473...

Perimeter = 2(22.8473) + 18 = 63.6946... ≈ 63.7 inches.

Which set of points includes all of the solutions for y = 5/2x + 3/2?

Firdavs [7]

Answer:

Choice A: $(x,\frac{5}{2}x+ \frac{3}{2} )$ . for all real numbers.

Step-by-step explanation:

We are looking for points on the x-y plane which satisfy the equation y = 5/2x + 3/2, and these point are all those that lie on the graph of the equation, which are points $(x,y) = (x,\frac{5}{2}x+ \frac{3}{2} )$ .

Looking at the other choices we see that choice B gives only 3 points, and regardless of whether they lie on the graph of y or not, this choice cannot be correct because 3 points are not all solutions.

The same goes for choice D.

And choice C is just the whole of x-y plane, therefore this cannot be the answer because not every point on the x-y plane is a solution to y = 5/2x + 3/2
