The graph has a slope of 2 because for every 2 units it rises, it moves to the right 1 unit. We also know the y-intercept is y=4.
So the equation disregarding the inequality is:
y = 2x + 4
Since the area ABOVE the curve is shaded, that means that y is greater than 2x+4. The dotted line means that it is strictly greater than and not equal to.
So now we have y > 2x + 4
We can rearrange our answer to get 4x - 2y < -8 which is the correct answer.
Answer:
28%
Step-by-step explanation:
We know that 100 percent is total. Mateo first scored 68/100, then a retake got his score up to 94/100.
First, subtract the two numbers
94 - 68 = 26
Put 26 over 94 to make this 26/94
Divide to get 0.28 (simplified and rounded)
So the increase was 28%

Answer:
C. This star has 5-fold reflectional symmetry and rotational symmetry of order 5.
Step-by-step explanation:
Proving the converse of the Pythagorean Theorem means proving that if the <u>sum</u> of the squares of the lengths of the <u>shorter</u> sides of a triangle equals the square of the length of the <u>longest</u> side, then the triangle is a right angle triangle.
Here's the equation:
(short side)² + (short side)² = (long side)²
