Express x in terms of a and b: b−7x=a−b

Answers

Answer 1

Answer: b - 7x = a - b
Subtract b from both sides.

-7x = a - 2b
Divide both sides by -7.

x = $(-a + 2b)/(7)$

For #3:

y = 1/2x, x = -18

Plug in -18 for 'x':

y = 1/2(-18)

y = -9

For #4:

y = -4x + 6, x = 1

Plug in 1 for 'x':

y = -4(1) + 6

y = -4 + 6

y = 2

1. $(2,3),(6,4),(8,11),(10,4)$
2. $(7,-13),(9,-9),(11,-5),(14,-1)$
Both relations are functions.

3. $y(-18)=(1)/(2)\cdot(-18)=-9$
4. $y(1)=-4\cdot1+6=-4+6=2$

5. It's easy to notice it's a linear function.
$y=mx+b\nm=(y_2-y_1)/(x_2-x_1)\n\nm=(-10-(-5))/(2-1)\nm=(-5)/(1)\nm=-5\n\n-5=-5\cdot1+b\nb=0\n\n\boxed{y=-5x}$

Write each of the numbers 1, 4, 9, 16, and 25 as a base raised to the second power. Explain why these numbers are sometimes called "perfect squares"

Answers

1 as a base raised to the second power is $1^2 = 1$
4 as a base raised to the second power is $2^2 = 4$
9 as a base raised to the second power is $3^2 = 9$
16 as a base raised to the second power is $4^2 = 16$
25 as a base raised to the second power is $5^2 = 25$
They are perfect squares because their square roots are whole numbers.

--------------------------

A number x as a base raised to the second power is written as:

$x = √(x)^2$

--------------------------

1, 4, 9, 16, and 25

We find the square root of each of these numbers, so:

Since $√(1) = 1$ , 1 as a base raised to the second power is $1^2 = 1$ .

Since $√(4) = 2$ , 4 as a base raised to the second power is $2^2 = 4$

Since $√(9) = 3$ , 9 as a base raised to the second power is $3^2 = 9$

Since $√(16) = 4$ , 16 as a base raised to the second power is $4^2 = 16$

Since $√(26) = 2$ , 25 as a base raised to the second power is $5^2 = 25$

--------------------------

Each number that has a whole square root is called perfect square, which is the case for 1, 4, 9, 16, and 25.

A similar question is found at brainly.com/question/2675310

First, we can raise each number to the second power by multipying it by itself. :)
1^2=1
4^2=16
9^2=81
16^2=256

These numbers are called "perfect squares" because their square roots are whole numbers, rather than decimals. For example, If you had a square with an area of 16, the side legnths of the square would be the whole (thus "perfect") number 4. For this reason, 16 (4^2) is considered a "perfect square" number. I hope that makes sense!! :)
