The standard form: Ax + By = C.


y=-\dfrac{1}{2}x+4\qquad\text{multiply both sides by 2}\\\\2y=-x+8\qquad\text{add x to both sides}\\\\\boxed{x+2y=8}

In standard form it would be x + 2y = 8.

x + 2y = 8

2y = -x + 8

y = -1/2x +4

If you are at mile marker 100 when you start your trip and mike marker 300 four hours later, where were you after 3 hours (assum
Marysya12 [62]

After 3 hours, you will be on 450 mile marker.

Step-by-step explanation:

<u>step 1:</u> At start, the number in the mile marker is 100

<u>step 2:</u> After 4 hours, the number in the mile marker is 300

<u>step 3:</u> The difference of 300-100= 200. In 4 hours you crossed 200 mile markers.

<u>step 4:</u> Therefore, for 1 hour you can cross= 200/4= 50 mile markers.

For 3 hours, the number of mile markers crossed= 3*50= 150 mile markers.

<u>step 5:</u> After 3 hours, the number in the mile marker will be= 300+150= 450

If the diameter of circle a measures half of the diameter of circle b, then the area of circle b is how many times the area of c
Eduardwww [97]
Circle b:

Diameter = x

Radius = \frac{x}{2}

Area = \pi  r^{2} =  \pi ( \frac{x}{2} )^{2} =   \frac{ \pi  x^{2} }{4}

Circle a:

Diameter = \frac{x}{2}

Radius = \frac{x}{2} *  \frac{1}{2} =  \frac{x}{4}

Area = \pi  r^{2} =  \pi  ( \frac{x}{4} )^{2} =  \frac{  \pi x^{2} }{16}

Thus,

Area of circle b to area of circle a

= \frac{ \pi x^{2} }{4} ÷ \frac{ \pi x^{2} }{16}

= \frac{ \pi x^{2} }{4} × \frac{ 16 }{\pi x^{2}}

= 4

Hence, the area of circle b is 4 times the area of circle a.
