How do you solve -3x+28=10

Answer: x = 6

Step-by-step explanation: To solve for <em>x</em>, we must first isolate the term containing <em>x</em> which in this problem is -3x.

Since 28 is being added to -3x, we subtract 28 from both sides of the equation to isolate the -3x. On the left, the +28 and -28 cancel out and on the right 10 - 28 is -18 so we have -3x = -18.

Now we can finish things off by just dividing both sides of the equation by -3. On the left the -3's cancel and we have <em>x</em>. On the right, -18 divided by -3 is 6 so we have x = 6 which is the solution to our equation.

Pavel [41]

Answer:

1) -5 and +5; 2) -9 and +9

Step-by-step explanation:

1) a² + 2ab + b² = 25

(a + b)² = 25 Wrote the left-hand side as a square

a + b = ±5 Took the square root of each side

All values of a + b are -5 and +5.

2) a² − 8ab + 16b² = 81

(a - 4b)² = 81 Wrote the left-hand side as a square

a - 4b = ±9 Took the square root of each side

All values of a - 4b are -9 and +9.

Write the function for the graph.

masha68 [24]

Answer:

answer is (a)

Step-by-step explanation:

first thing we should find the equation which is f(X)=a*b^x

so the always will be the y intercept no matter what

now time to find b if graph that is shown start from 1 until the end of line which is in the graph so you will find it 8 now divide 8 by 4 so 8/4=2

so final equation will be f(x)=2*(4)

i hope i helped out

What is the solution to the system of equation -4+3y=-3

Shalnov [3]

Answer:

$\huge\boxed{\sf y = 1/3}$

Step-by-step explanation:

<h3>Given equation:</h3>

-4 + 3y = -3

Add 4 to both sides

3y = -3 + 4

3y = 1

Divide 3 to both sides

<h3>y = 1/3</h3>
