Answer:
f(3) = 10
Step-by-step explanation:
If x = 3 then fill in the x's on the original equation and solve;
f(x) = 2x + 4
f(3) = 2(3) + 4
2 x 3 = 6
6 + 4 = 10
So, f(3) = 10

Let the third angle of the triangle be y.
y + 64° + 45° = 180° (angle sum of triangle is 180°)
x + y = 180° (angle of a straight line is 180°)
Notice that they both equal 180°. This means that they are the same thing, hence:
y + 64° + 45° = x + y
Since y = y, it is not necessary to write them down. Remove y from both sides of the equation:
64° + 45° = x
Surprise! exterior angle = sum of interior opposite angles.
I hope this clears up any confusion you might have. If not, feel free to leave a comment with your question.
The amount she had after the pants is $37.50
the you take $37.50 divide it by 3 and you get $12.50 so each shirt would cost $12.50
For 10, the slope is 1/2 and the y intercept is 0. For 12 i believe its 4 for both the slope and the y intercept.
CDE is the line segment, in which CE = 17.1, and DE = 8
Subtract 8 from 17.1
17.1 - 8 = 9.1
CD = 9.1
hope this helps
