Answer:
down
Step-by-step explanation:
y = -3x^2 +x +1
The coefficient of the x^2 term is negative so it opens facing down
X^2 coeffient
- means down
+ mean up
Answer:
38
Step-by-step explanation:
Notice that the first triangle is an isosceles triangle, meaning that the base angles are equivalent. Since one angle is 62, we know that the other is 62 as well, which makes 124. This means that angle 2 is 56 degrees. Since 2 and 3 are on the same 'line', they both add up to 180. If 2 is 56, then angle 3 is 124. So the three angles inside the triangle are 124, 18, and x. So, 124+18=142. 180-142= 38
Answer: 2/20, because all those marbles in total is 100. the blue and black marbles would be 70, if you simplify all of it it'd be 2/25.
