zubka84 [21]2 years ago
8 0

Step-by-step explanation:

Equation of line is y-y1 = m(x-x1), where m is the slope and (x1,y1) is the given point.

y-2 = 1/4*(x-(-4))

y-2 = 1/4 * (x+4)

4*(y-2) = x+4

Equation of the line is,

x-4y = -12

How can you compare prices at two different stores by finding the constant of proportionality
dimaraw [331]

Answer:

The constant of proportionality gives you the price per unit at each store.

Step-by-step explanation:

If you assume that the price (y) is directly proportional to the amount (x) you get, the formula is

y = kx

where k is the constant of proportionality.

k = y/x

k has the units of cost per unit, for example, dollars per ounce.

The fewer the dollars per ounce, the better the deal you are getting.

If store A offers apple sauce at $1.29 for 25 oz and Store B offers apple sauce at $2.89 for 50 oz, which is the better deal?

At store A, k = $1.29/25 oz = $0.052/oz or 5.2¢/oz

At store B, k = $2.89/50 oz = $0.058/oz or 5.8¢/oz

The apple sauce is cheaper at Store A.

2x(x - 3) + 7(x - 3)<br> Can I have an explanation on how it works factors
Nimfa-mama [501]

Answer:

Step-by-step explanation:

2x(x - 3) + 7(x - 3)

2x^2 - 6x + 7x - 21

reduce

2x^2 + x - 21

if this is equal to 0 then:

2x^2 + x - 21 = 0

factored:

(2x + 7)(x - 3) = 0

How that was done:

Divide the (2x^2) into (2x) and (x).

Divide the (-21) into (+7) and (-3). You choose these numbers so that their sum, when multiplied by (2x) and (-3), adds up to (+x).

For the solution (x,y) to the system of equations what is the value of x- y? 7x+3y=8 6x-3y=5
stiv31 [10]

Answer:

  2/3

Step-by-step explanation:

Let's  define z = x-y, so solving for z will tell us exactly what we want to know. Then we can substitute for x: x = z+y, and our equations become ...

  7(z+y)+3y = 8   ⇒  7z +10y = 8

  6(z+y)-3y = 5   ⇒   6z +3y = 5

We can eliminate the y-variable by subtracting 3 times the first equation from 10 times the second:

  10(6z +3y) -3(7z +10y) = 10(5) -3(8)

  60z +30y -21z -30y = 50 -24 . . . . eliminate parentheses

  39z = 26 . . . . collect terms

  z = 26/39 = 2/3 . . . . . divide by the coefficient of z and reduce

The value of x - y is 2/3.

_____

The attached graph shows (x, y) = (1, 1/3), so x - y = 1 - 1/3 = 2/3.
