Answer:
x = 25
Step-by-step explanation:
A segment joining the midpoints of 2 sides of a triangle is half the length of the third side, that is
x - 8 =
× 34 = 17 ( add 8 to both sides )
x = 25
The equation:
![y=12+10x](https://tex.z-dn.net/?f=y%3D12%2B10x)
models the amount of money in your wallet. Where:
x: Represents the number of weeks from today
y: Represents the total in dollars
This graph is indicated in the figure bellow. The slope of this graph is 10, that is, the term accompanying the variable x. The slope of a line is the number of units the line rises (or falls) vertically for each unit of horizontal change from left to right. So, in this problem, this represents how much your adding to your wallet each week. You are adding $10 dollars for x weeks.
Answer:
11.6--------------------------------------
Explanation:
See the attached image for a visual reference
The distance from point D to E is 21 units. Point C is the midpoint, so CD is 10.5 units long (21/2 = 10.5)
We have a right triangle ACD. The legs are
AC = 5
CD = 10.5
The hypotenuse is
AD = x
Because AD is another radius of the same circle
Use the pythagorean theorem to find x
a^2 + b^2 = c^2
5^2 + 10.5^2 = x^2
25 + 110.25 = x^2
135.25 = x^2
x^2 = 135.25
x = sqrt(135.25)
x = 11.629703349613
which rounds to
11.6 when rounding to the nearest tenth (one decimal place)
Answer:
Function
Step-by-step explanation:
This is a function
Each input goes to only one output
To answer this question, substitute the number of tickets sold for the x value.
y = 3.4(15) + 43
Solve the equation by first multiplying the 3.4 and the 15.
3.4 x 15 = 51
This leaves your equation looking like this:
y = 51 + 43
The final step is to add he two integers together.
51 + 43 = 94
So the final answer is y = 94
