Answer:
Step-by-step explanation:
<u>Given function:</u>
<u>Convert the equation into vertex form:</u>
- y = 5x² - 20x + 20 + 4 =
- 5(x² - 4x + 4) + 4 =
- 5(x - 2)² + 4
Vertex is (2, 4) at which the minimum y-value is 4
Correct choice is C
Answer:
7.)C
8.)B
9.)B
10.)D (I think)
11.)B (yet again I think)
I'm not 100% sure on the last two
hope this helped
we know the x-intercept of the line is 1, recall that an x-intercept is when the graph intercepts or touches the x-axis, and when that happens, y = 0, so the point is really x = 1, y = 0, namely (1,0). We also know another point on the line, is (-2, 9).
Answer:
x=11°
Step-by-step explanation:
-Sum of angles of a triangle should alway be 180 degrees
35+110+2+3x=180
-Add all known values
147+3x=180
-Subtract 147 from both sides
3x=33
-Isolate x by divind both sides by 3
x=11°
-4 is less than -5 even though they are both on the same side of the number line. -4 is closer to zero.
