There are two variables: time(dependent) and number of handbag(independent). Time changes as the number of hand bags changes.

Answer: Introduction to Functions Unit Test

No, The points are random

The time increases while the number of bags do too. The time is independent and the bags are dependent.

A. P (t)= (P-5)+0.05 (P-5)+1.05(P-5)

B.Pt=1.05(P-5)=1.05(15.50-5)=$11.03

Yes, the points make a straight line

Y=x+1 y=x^2-1 please help i don't understand

ANSWER

The solution is

$(x=1,y=2),(x=2,y=3)$

EXPLANATION

We have

$y=x+1---(1)$

and

$y=x^2-1---(2)$

Let us substitute equation (1) in to equation (2). This gives us,

$x+1=x^2-1(2)$

We rewrite this as a quadratic equation as the highest degree is 2.

$x^2-x-1-1=0$

This implies that

$x^2-x-2=0$

we factor to obtain,

$x^2+x-2x-2=0$

$x(x-1)-2(x-1)=0$

$(x-1)(x-2)=0$

This means,

$(x-1)=0\:\: or\:\:(x-2)=0$

$x=1\:\: or\:\:x=2$

We substitute this values into any of the above equations, preferably equation (1)

When, $x=1$ , $y=1+1=2$

When, $x=2$ , $y=2+1=3$

The solution is

$(1,2),(2,3)$

Ashley increased the amount of water she drinks each day from 80oz to 87 oz.By what percentage did she increase her water intake

rewona [7]

87oz - 80oz = 7oz
7oz/80oz = 0.0875
0.0875 x 100% = 8.75%

Ashley increased her water intake by 8.75%.
