what does x=? I know it is vertical

Answers

the angles are supplementary

7x + x + 20 = 180
8x = 160
x = 20

Hello there!

We know a vertical line = 180 degrees

x + 20 + 7x = 180

we can simplify this

20 + 8x = 180

To solve this, we can work backwards.

180 - 20 = 160

8x = 160

160/8 = 20

x = 20 degrees

Answers

F(-3) = 4(-3) - 3 = -12 - 3 = -15.
H(2) = -5(2) + 7 = -10 + 7 = -3.

F(-3) + H(2) = -15 + -3 = -18.

The solution is -18.

Answer:

F(-3) = 4(-3) - 3 = -12 - 3 = -15.

H(2) = -5(2) + 7 = -10 + 7 = -3.

F(-3) + H(2) = -15 + -3 = -18.

The solution is -18.F(-3) = 4(-3) - 3 = -12 - 3 = -15.

H(2) = -5(2) + 7 = -10 + 7 = -3.

F(-3) + H(2) = -15 + -3 = -18.

Hannah keeps her marbles in bags with for marbles in each bag she writes 3/4 to show the number of red marbles in each bag find another fraction to name the number of red marbles in 2 bags

Answers

She keeps 4 marbles in every bag and mark it with 3/4 to represent red marbles in the bag. It means there are 3 Red marbles out of total 4 marbles in the bag.

It says to write another fraction to represent number of red marbles in two bags.

Since one-bag contains 3 Red marbles out of total 4 marbles in the bag.

Then two-bags would contain 2x3 Red marbles out of total 2x4 marbles in the bag i.e. 6 Red marbles out of total 8 marbles in the bag.

So, [tex] \frac{6}{8} [/tex] is the another fraction to show number of red marbles.

How to find turning point of (c-2)^3+8

Answers

A "turning point" is generally considered to be a point where the first derivative changes sign. This function does not meet that requirement anywhere.

The function has a point of inflection at (2, 8), where the curve is horizontal, but does not reverse direction.

hello there!

to find the turning point, you must have a function, so let's set this expression equal to y.

y=(c-2)^3+8
y'=3(c-2)^2

Now set y' equal to 0...

3(c-2)^2=0
3(c-2)(c-2)=0
c=2

Now that we know c=2, plug this in to the original equation to get the y-value for the turning point.
The turning point is (2,y) we will find y now...
y=(2-2)^3+8
y=0+8
y=8

The turning point is at (2,8)

The explanation for this is that the x values of the zeros of the derivative function are the same as the x values as the turning points on the original function.

I really hope this helps!

which collection of three side lengths will not form a triangle

6, 10 18
10, 12 ,15
10, 15, 6
10, 18 ,12 please tell me how you figured it out.

Answers

To construct a triangle, the sum of any 2 sides of the triangle should be greater than the third side of the triangle.
lets calculate the sums of all the given choices to find out which three lengths given do not form a triangle.

A.
6,10,18
6 + 10 = 16
16 is smaller than the third side-18
Therefore these 3 lengths do not form a triangle

B.10,12,15
10 + 12 = 22 15+12 = 27 15 + 10 = 25
22>15 (3rd side) 27>10 (3rd side) 25>12 (3rd side)
In this triangle, sum of all the possible pairs of sides are greater than the third side therefore these lengths can form a triangle

C.10,15,6
10 + 15 = 25 15 + 6 = 21 10+6 = 16
25 > 6 21>10 16>15
in this too, sum of all the possible pairs of sides are greater than the third side. These lengths can be used to form a triangle

D.10,18 ,12
10 + 18 = 28 18 + 12 = 30 10 +12 = 22
28> 12 30>10 22> 18
Therefore these lengths can also be used to form a triangle

correct answer is 6,10 and 18 these cannot form a triangle

Final answer:

To determine if a collection of three side lengths will form a triangle, we use the triangle inequality theorem. This theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. By applying this theorem to each collection of side lengths given, we can determine which ones will form a triangle.

Explanation:

A triangle is a three-sided figure lying on a plane with three angles adding up to 180 degrees. To determine if a collection of three side lengths will form a triangle, we use the triangle inequality theorem. According to this theorem, the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

For the collection 6, 10, 18, the sum of the two smaller sides (6 + 10) is less than the largest side (18), so this collection will not form a triangle.For the collection 10, 12, 15, the sum of the two smaller sides (10 + 12) is greater than the largest side (15), so this collection will form a triangle.For the collection 10, 15, 6, the sum of the two smaller sides (6 + 10) is greater than the largest side (15), so this collection will form a triangle.For the collection 10, 18, 12, the sum of the two smaller sides (10 + 12) is greater than the largest side (18), so this collection will form a triangle.
