Answer:

24 weeks

Step-by-step explanation:

He now has $50.

He just spent $142.

Before spending the $142, he had a total of

$142 + $50 = $192

He had saved a total of $192.

He saves $8 per week.

$192/$8 = 24

He saved for 24 weeks.

Question 1

Bad White [126]

Answer:

n = -15 and n = 9. n = -15 is not reasonable because you can't have negative boxes or negative units of measurement.

Step-by-step explanation:

8(n + 2)(n + 4) = 1,144

(n + 2)(n + 4) = 143

n^2 + 2n + 4n + 8 = 143

n^2 + 6n - 135 = 0

(n + 15)(n - 9) = 0

n + 15 = 0

n = -15

n - 9 = 0

n = 9

I got two solutions: n = -15 and n = 9. Only one is reasonable because you cannot have a negative number of boxes or negative weight.

Hope this helps!

if trangle pqr is translated 4 units to the right to form triangle p'q'r' how are the values on the orderd pairs affected by the

Vesna [10]

Answer:

The x-coordinate of each point will increase by 4.

Step-by-step explanation:

So Triangle PQR is being translated 4 units to the <em>right</em>. Since we are going to the <em>right</em>, this is a shift on the x-coordinate.

And since we're going 4 units, every x-coordinate is going to be added by 4.

In other words, if we have:

$A(x,y)$

Then the new coordinate, A', is:

$A(x,y)\rightarrow A' (x+4,y)$

So, let's find the new coordinates of each point.

Point P is (-5,6). So:

$P(-5,6)\rightarrow P'(-5+4,6)=P'(-1,6)$

The new Point P is at (-1,6).

Point Q is at (2,6). So:

$Q(2,6)\rightarrow Q'(2+4,6)=Q'(6,6)$

The new Point Q would be at (6,6).

And Point R is at (-3,2). So:

$R(-3,2)\rightarrow R(-3+4,2)=R(1,2)$

The new Point R is at (1,2).

And we're done!
