Answer:

1. 4z=-8

z= -8/4= -2

2. 2/3t=8/1

2= 24t

t= 0.08

3. 15-1=-8d

14=-8d

d= -1.75

4. 5r-2r=18

3r= 18

r= 6

5. 24= 8y

y=3

6. 3t-3= -t+5

3t+t= 5+3

4t=8

t=2

7. 2x-x= 3+6

x=9

The coordinate (1,3) is a solution to 2x-3y=-7 True False

Natalija [7]

True because just plug in (1,3) for x and y and solve it out.
Plugging it in gives you 2(1)-3(3)=-7 which simplifies to 2-9=-7, which is true.

Find the range of the following piecewise function.

mash [69]

Answer:

$\huge\boxed{[-5;\ -2)\ \cup\ [3;\ 13)}$

Step-by-step explanation:

The following piecewise functions are linear functions. The graph of any of them is a line segment.

We just need to calculate the value of the function at each end specified in the brace.

$y=3x-2\ \text{if}\ -1\leq x$

Substitute x =-1 and x = 0:

$x=-1\\y=3(-1)-2=-3-2=-5\\\\x=0\\y=3(0)-2=0-2=-2$

Range of this piece is [-5; -2)

$y=2x+3\ \text{if}\ 0\leq x$

Substitute x =0and x = 5:

$x=0\\y=2(0)+3=0+3=3\\\\x=5\\y=2(5)+3=10+3=13$

Range of this piece is [3; 13)

Therefore the range of the following piecewise function is:

$[-5;\ -2)\ \cup\ [3;\ 13)$

Look at the picture.
