Rus_ich [418]

Answer:

3 oil changes

Step-by-step explanation:

1. Find an equation that represents this word problem: 3000x + 5000 = y

Where y = the # of miles total. y = 250 miles/week * 52 weeks/year = 13000 miles.

2. Solve for x: 3000x + 5000 = 13000 3000x=8000

3. x = 8/3 integer round down x = 2 oil changes, but plus the one after 5000 miles is a total of 3 oil changes that year

Answer:

$\large\boxed{y-2=-2(x+3)}$

Step-by-step explanation:

The point-slop form of an equation of a line:

$y-y_1=m(x-x_1)$

m - slope

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (-3, 2) and (-7, 10). Substitute:

$m=\dfrac{10-2}{-7-(-3)}=\dfrac{8}{-4}=-2\\\\y-2=-2(x-(-3))\\\\y-2=-2(x+3)$

An architect is sketching a blueprint of a patio for a new fence. On the blueprint, C is the midpoint of segment AD. Point B is

Gre4nikov [31]

Answer:

The length of AD is 32 feet

Step-by-step explanation:

Proportional distances

When distances are proportions of others, we can express all of them as relative fractions until we reach some known distance and solve for the desired length

Let's call x the length of AD. Given C is the midpoint of AD, then

$\displaystyle AC=CD=\frac{x}{2}$

Given B is the midpoint of AC, then

$\displaystyle AB=BC=\frac{AC}{2}=\frac{x}{4}$

If we know BC=8 feet

$\displaystyle \frac{x}{4}=8\ feet$

$\displaystyle x=32\ feet$

The length of AD is 32 feet
