Answer:
The x-coordinates of the points are x = 3 and x = - 8.
Step-by-step explanation:
We have to find the x-coordinates of the points where the graph of equation y = (x - 3)(x + 8) crosses the x-axis.
Now, the x-intercept of a function implies that y = 0 {Because on x-axis, y-value is zero}
Hence, (x - 3)(x + 8) = 0
⇒ (x - 3) = 0 and (x + 8) = 0
⇒ x = 3 and x = - 8
Therefore, the x-coordinates of the points are x = 3 and x = - 8. (Answer)
Answer:
70°
Step-by-step explanation:
every triangle has a total of 180°, therefore 180-80-30=70°
i apologize if my answer is incorrect!
3(x-1)^2 +2
This is your answer in vertex form, your h and k values are the vertex. Solving the function by using b/2a, we get that h is 1. ( in the equation 3 is your a, 6 is b and 5 is c.). ( 6/2(3)) = 1. We can then plug in 1 as x into the original equation and get positive 2 ( 3(1)^2 -6(1) +5) = 3-6+5 = 2. This is your vertex. In the function, your a value will always stay the same as this is your shrink or stretch. In this case, a is 3 so it will go outside the parenthesis. Put that all together and you get the function above.
Hope this helps :)
