Answer:

(-8,4)

Step-by-step explanation:

Given: 2x-3y=-28 and x+6y=16

solve for a variable and then substitute back into other equation

x + 6y = 16

x = 16 - 6y; now use this in the other equation

2x - 3y = -28; substitute into x

2(16 - 6y) - 3y = -28; distribute 2

32 - 12y - 3y = -28; combine y's

32 - 15y = -28; isolate 15y

32 + 28 = 15y; add the numbers

60 = 15y; divide by 15

y = 4

Now use this to plug into other equation

x + 6y = 16; y=4

x + 6(4) = 16;

x + 24 = 16; subtract 24 from both sides

x = -8

Apply your knowledge of square roots to solve equations involving them. Show your step-by-step solution. Remember, each problem
Elena L [17]
Remember to include the positive and negative roots


(7x-2)^2=256
sqrt both sides
7x-2=+/-16
add 2 to both sides
7x=2+/-16
divdide both sides by 7
x=(2+/-16)/7)

x=(2+16)/7=18/7=2 and 4/7
x=(2-16)/7=-14/7=-2

x=2 and 4/7 or -2

Using the table, which value from the domain corresponds to a range value of 3?
ozzi
We know that

A range value of 3 that means 
that the value of y is 3

<span>observing the table we see that for y = 3  the value of x is 0
therefore
the value of the domain for the range 3 is 0

the answer is
0
