I believe x is 43.
3x+17+x-9=180 It is 180 because a straight line is 180 degrees
4x+8=180
-8 -8 subtraction property of equality
---------------
4/4x=172/4 division property of equality
x=43 solution
Answer:
eccentricity; e = 1/7
k = 12
Conic section; Ellipse
Step-by-step explanation:
The first step would be to write the polar equation of the conic section in standard form by multiplying the numerator and denominator by 1/7;

The polar equation of the conic section is now in standard form;
The eccentricity is given by the coefficient of cos theta in which case this would be the value 1/7. Therefore, the eccentricity of this conic section is 1/7.
The eccentricity is clearly between 0 and 1, implying that the conic section is an Ellipse.
The value in the numerator gives the value of k; k = 12
F(x)= 12 / (4x+2 )
f(-1) mean to replace x by (-1)
so, f(-1) = 12 /(-4+2)
f(-1)= 12/-2
f(-1) = -6
Answer:
10 miles per week
Step-by-step explanation:
The dots are placed 2 units higher when it goes 1 unit to the left. The 2 units up is 10 miles while each unit to the right is 1 week because of the labels on the left and bottom of the graph.
