Hello. This might not be the least of helpful but your over thinking this a little bit to much, this is very easy so here is what I want you to do, I want you to calm down and clear everything out of your mind, then you'll start seeing things you haven't. I'm a sixth grader studying 7th grade math, I over think the questions to much so I have a hard time also please don't watch YouTube while doing your homework

In the triangle above, the measure of A is 66°, and the measure of B is 68°. What is the measure of C?
valentina_108 [34]

Answer:

46°

Step-by-step explanation:

Given that :

Angle, A = 66°

Angle B = 68°

The sum of angles in a triangle is given by :

A + B + C = 180° (sum if angles una triangle)

66° + 68° + C = 180°

134° + C = 180°

C = 180° - 134°

C = 46°

Hence, angle C is 46°

Erica had 6 coins in her coin collection. She goes to a coin show and buys some more coins. How many coins does she have now?
goldfiish [28.3K]

Answer:

6+x with x equalling the amount of coins bought if that is what you were looking for

Step-by-step explanation:

if you want to make and equation out of this you don't know the amount of coins she bought so you use a variable (x) to replace that unknown number then since it says she bought more she is adding more to her collection which means it would be an addition problem, leaving you with 6+x for your final answer

What is the equation written in vertex form of a parabola with a vertex of (–1, 8) that passes through (1, 0)?
Archy [21]

Answer:

y = -2(x + 1)^2 + 8

Step-by-step explanation:

The equation of a parabola can be written in the form;

y = a(x-h)^2 + k

where a is the multiplier (h,k) is the vertex

so h = -1 and k = 8

Plug in these values

y = a(x + 1)^2 + 8

So to get the value of a, we use the point where the parabola passes through which is the point (1,0)

Simply substitute the values of x and y

0 = a(1 + 1)^2 + 8

0 = a(2)^2 + 8

-8 = 4a

a = -8/4

a = -2

So therefore the equation of the parabola is ;

y = -2(x + 1)^2 + 8
