A number increased by 4 is the same as 19 minus 2 times the name in equation form

X+4=2x-19

x = 23

subtract x from left side and add 19 to right side.

the cost in dollars of a loaf of bread in a bakery is equal to 2 minus 0.25 times the number of days since it was baked. Is ther

Ierofanga [76]

We are given

Let's assume

number of days =x

the cost in dollars of a loaf of bread in a bakery =y

we have

the cost in dollars of a loaf of bread in a bakery is equal to 2 minus 0.25 times the number of days since it was baked

so, we get

$y=2-0.25x$

It will not make sense when cost is negative

so, we set y=0

and then we can solve for x

$0=2-0.25x$

We add both sides by 0.25x

$0+0.25x=2-0.25x+0.25x$

$0.25x=2$

Divide both sides by 0.25

and we get

$x=8$

So, after 8 days , the cost will become negative

which does not make sense

because cost can never be negative ............Answer
