Answer:
I think the answer is: y = 0.5x^2 + 4x + 6, <3
Step-by-step explanation:
I believe it should be ∆LKD because the parts should correspond with each other. D is a right angle in the first triangle and appears in the middle, so since K is the right angle of the second, it should also go in the middle.
I believe this is proven by HL because both hypotenuses are congruent, as is a pair of legs, and they are both right triangles.
Answer:
The shape is plane, a rectangle
Step-by-step explanation:
The external figure, the cylinder is a rectangle in a two dimensional plane, so the cross section between two rectangles is also a rectangle
Answer:
1. x = 1, y = -3
2. x = 3, y = 4
Step-by-step explanation:
Here, we want to solve the sets of simultaneous equations;
a) -y = 5x-2
-3y = -5x + 14
substitute 1 into ii
3(5x-2) = -5x + 14
15x - 6 = -5x + 14
15x + 5x = 14 + 6
20x = 20
x = 20/20
x = 1
from;
-y = 5x - 2
y = -5x + 2
y = -5(1) + 2
y = -3
b) -2y = -6x + 10
2y = x + 5
Substitute ii into i
-(x + 5) = -6x + 10
-x - 5 = -6x + 10
-x + 6x = 10 + 5
5x = 15
x = 15/5
x = 3
2y = x + 5
2y = 3 + 5
2y = 8
y = 8/2
y = 4
