Find solutions between the intervals
-3, -2, -1, 0, 1, 2, 3

You got the basic idea how to solve it but:

when you have 2^-3, it's not -8
2^-3 = 1/2^3 = 1/8
same goes with -2 and -1

When you have negative power you basically divide n^-x = 1/n^x

How many solutions does the system 2y=10x-14 and 5x-y=7 have? need worked out step by step please!
VLD [36.1K]
2y=10x-14
5x-y=7

Divide both sides by 2 in the 1st equation
y=5x-7
Now substitute is to 2nd equation 
5x-5x+7=7
0=0

Therefore there is no solution or it is inconsistent

Step-by-step explanation:

\sqrt[3]{216} = \sqrt[3]{8} · \sqrt[3]{27}  =  \sqrt[3]{2}³ · \sqrt[3]{3}³ = 2 x 3  = 6

I need answers for 1 and 2
Snowcat [4.5K]

1. Slope 3/4, through (4,-1)

y = 3/4 x + b

-1 = 3/4(4) + b

-1 = 3 + b

-1 - 3 = b

-4 = b

y = 3/4 x - 4

2. Slope = - 1/2, through (3,0)

y = -1/2 x + b

0 = -1/2(3) + b

0 = -1.5 + b

0 + 1.5 = b

1.5 = b

y = -1/2 x + 1.5
