Hi,
Let assume y=x-2, so x=y+2

f(x-2)=2x-4\\

f(y)=2(y+2)-4\\

f(y)=2y+4-4\\

f(y)=2y\\

<u>f(x)=2x</u>

A shelter has enough food to feed an average of 80 hungry people a day for 14 days. If an average of 32 people are at the shelte
Katen [24]

Answer:

  • <u>35 days. </u>

Explanation

The capacity of the shelter is a constant. It is 80 people × 14 days.

That is an inverse relation: the product of the number of people and the number of days will be always the same.

As the number of people decreases the number of days that the food lasts increases, in a proportion such that the product of the days and the number of people is the same.

Thus, for 32 people the number of days the food lasts is x, such that:

  • 32 people × x = 80 people × 14 days

Solving for x:

  • x = 80 people × 14 days / 32 people
  • x = 35 days ← answer

The food will last 35 days.

soldier1979 [14.2K]
Well, the give us 1990-2006 as the time period. If you don't know how many years that is and don't feel like counting: 2006-1990=16


Then plug it in the equation t=16
E(t)=204(1.04)t
E(16)=204(1.04)16
E(16)=212.16•16
E(16)=3394.46

If you manipulated a matrix so all the entries above the diagonal entries are 0s, how would the solution differ from when made t
Lorico [155]

Answer:

(Exact Answer) When all the entries above the diagonal entries are 0, the solution will not be different from when all the entries below the diagonal entries are 0. This is because in both cases, there will be one row that would be left with just one unknown element, thus giving us the solution to the other unknowns through back-substitution. For instance, in a linear system with three unknowns, x, y, and z, the traditional triangulated form will give us the value of z first; however, if the entries above the diagonal entries in the matrix are 0, then we will get the value of x first. In either case, the solution will be the same.

Which lines are parellele
natali 33 [55]

Line 1 and Line 4 are parallel lines

Solution:

General equation of a line:

y = mx + c

where m is the slope and c is the y-intercept of the line.

<u>To find the slope of each line:</u>

Line 1: y=-\frac{3}{4} x-6

Slope (m_1)=-\frac{3}{4}

Line 2: y-7=-4(x+9)

y-7=-4x-36

Add 7 on both sides, we get

y=-4x-29

Slope (m_2)=-4

Line 3: y=-2 x+6

Slope (m_3)=-2

Line 4: x+\frac{4}{3} y=-5

Subtract x from both sides, we get

\frac{4}{3} y=-x-5

Multiply  by \frac{3}{4} on both sides, we get

y=-\frac{3}{4}x-\frac{15}{4}

Slope (m_4)=-\frac{3}{4}

<em>Two lines are parallel, if their slopes are equal.</em>

From the above slopes,

m_1=m_4

Therefore Line 1 and Line 4 are parallel lines.
