Answer:
the domain of a v-shaped graph is set of all real numbers
Step-by-step explanation:
Answer:
(2, 9)
x = 2
y = 9
Step-by-step explanation:
To solve this system, we can either use substitution or graph it. I will be showing how to graph it.
To solve by graphing, we graph both of the equations and find the point at which the lines intersect.

I think the shape is an right angel. And for the answer to h is 90° and i think for b it is 45°. I hope this helps :)
If the triangle has a right angle, the measure of the third side is 12.8 inches
a = 30
a = 16
-a² + 46a -480 = 0
(-a + 30) (a -16) = 0
(-a)(a) + (-a)(-16) + 30(a) + 30(-16) = 0
-a² + 16a + 30a -480 = 0
-a² + 46a - 480 = 0
(-a + 30) = 0 ; (a - 16) = 0
-a = -30 ; a = 16
a = 30
To check:
a = 30
-(30)² + 46(30) - 480 = 0
-900 + 1380 - 480 = 0
480 - 480 = 0
0 = 0
a = 16
-(16)² + 46(16) - 480 = 0
-256 + 736 - 480 = 0
480 - 480 = 0
0 = 0
