Answer:

y = 2.25x

Step-By-Step Explanation:

If I divide y by x, in any of the tables, it is always 2.25.

y ÷ x = 2.25

Then, I can multiply x on both sides to make the equation showing the proportional relationship.

y ÷ x × x = 2.25 × x

y = 2.25x

With the substitution method, which variable should you solve for first?
nignag [31]
It really does not matter, I tend to solve for x first simply because it comes before y, but you do whatever is easier for you.

Find the equation of a line that is parallel to y = 5x + 7 and passes through (4, 3)
vredina [299]

Answer:

B) y=5x-17

Step-by-step explanation:

I got this answer, by first making sure it was parallel to y=5x+7. Which was easy because the only thing they need to be parallel is the same slope, in this case was 5. Next I pluged in (4,3) to y=5x-17. I substituted 4 into x and got 20. Then I substituted 3 into y. Since 20-17 is equal to 3, then B. is your answer.

<u>Answer:</u>

x = 5.00 cm

<u>Step-by-step explanation:</u>

• area of the rectangle = x   x   (x + 1)

                                     = x^2 + x

• area of the circle = π r²

                               = \frac{22}{7}   x   (x + 2)^2

                               = \frac{22}{7}   x   (x^2 + 4x + 4)

∴   x^2 + x   +    \frac{22}{7}   x   (x^2 + 4x + 4)  = 184  

⇒  x^2 + x      +   \frac{22}{7}  x^2   \space\ + \space\ \frac{88}{7} x \space\  +  \space\  \frac{88}{7} = 184

⇒  \frac{29}{7}x^2 \space\  +  \space\  \frac{95}{7}x \space\ - \frac{1200}{7} = 0

• Using quadratic formula, where

a = \frac{29}{7}

b = \frac{95}{7}

c = \frac{-1200}{7} ,

x=\frac{-b \pm \sqrt{b^2-4c}}{2}

x = \frac{-\frac{95}{7}\pm \sqrt{(\frac{95}{7})^2 - 4(\frac{29}{7})(\frac{-1200}{7} )  }  }{2(\frac{29}{7})}

x = 5.00   \space\   \space\ \space\ or  \space\ \space\ \space\   x = -8.28

As length (x) cannot be a negative number,

x = 5.00 cm
