A number to the 0 power is 1, so your answer is correct.

y to the 4th power is equal to A because when you combine the two, you add their exponents.

It is also equal to B. y to the 6th power divided by y to the 4th power because when you divide two exponents, you just subtract. So that means it is equal to D.

The first group was responsible for making 160 suits while the second group was responsible for making 25% fewer suits in the sa

egoroff_w [7]

First group rate is x+10, Second is x
First group made 160, Second made 120
Time the first group will take is 160/x+10, and second is 120/x
Equation is: 160/x+10 + 4 = 120/x
x=10, x=-30
The second group made 10 suits everyday.

Answer:

only a is the right triangle

Step-by-step explanation:

only a is the right triangle because it satisfies the pythagorean theorem.

a.)

$c ^{2} = a ^{2} + b ^{2} \\ 63 = 25 + 38\\ 63 = 63 \\ true$

while b,

b.)

$c ^{2} = a ^{2} + b ^{2} \\ 60 = 25 + 38 \\ 60 = 63 \\ false$

What is the equation of a line that is perpendicular to y = 3x -2 and passes

White raven [17]

Answer:

A. y=-1/3x+10

Step-by-step explanation:

Perpendicular gradients(slopes) are negative reciprocals so

m=-1/3 then use the point (6,8) to find the equation of the line

y=mx+b

8=(-1/3)(6)+b

8=-2+b

b=10

y=-1/3x+10
