1st
Make a right triangle with legs 5, 12, and hypotenuse D. D is the distance you need.
Pythagorean Th
25 +144 = D^2
169 = D^2
D = 13
2. Plug in all the points...
B, D, F work
We know that
the x-intercepts of the quadratic function f(x)=x²<span>−3x−10 is when
f(x)=0
</span>x²−3x−10=0
Group terms that contain the same variable, and move the
constant to the opposite side of the equation
(x²−3x)=10
Complete the square. Remember to balance the equation
by adding the same constants to each side.
(x²−3x+2.25)=10+2.25
Rewrite as perfect squares
(x-1.5)²=12.25----------> (+/-)[x-1.5]=3.5
(+)[x-1.5]=3.5----> x1=5
(-)[x-1.5]=3.5-----> x2=-2
<span>
the answer is</span>
the x-intercepts of the quadratic function are<span>
x=5x=-2</span>
The answer is (-5,1) because 2(-5)-3(1)=-13 :)
Answer:
<em>- 4</em>
Step-by-step explanation:
( 3 - r ) / ( 1 + 5) = 7/6
= 
⇒ 3 - r = 7 ⇒ r = <em>- 4</em>
489.5 would be the answer :)
