Let x is the first no. then the other no. will obviously be (x+1)
according to question,
(x+1)²- x²= 15
x² +2x+1 - x² = 15 ( using (a+b)²= a²+ b² + 2ab )
2x + 1 = 15
2x = 14
x = 7
hence numbers are x = 7 and x +1 = 7+1 = 8
also 8²-7² = 64-49 = 15
hence the numbers are 7 and 8
hope it helped
Slope= 5
X-intercept= -5/5 = -1
Y-intercept= 5/1 = 5.0000000
Answer:
x=33.4
Step-by-step explanation:
The answer is <span>D. –1 + 2 = 1
</span>
The vertex of the parabola is <span><span>(<span>2,1</span>)</span><span>(<span>2,1</span>)</span></span>
.
So, the axis of symmetry is the line <span><span>x=2</span><span>x=2</span></span>
.
