3. A straight line passes through two points with

kirza4 [7]

Answer:

Step-by-step explanation:

Find the slope of the line

(x₁ , y₁) = (6 , 8) & (x₂ , y₂) = (0 , 5)

$Slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\frac{5-8}{0-6}\\\\=\frac{-3}{-6}\\\\=\frac{1}{2}$

m = 1/2 ;(x₁ , y₁) = (6 , 8)

y - y₁ = m(x - x₁)

$y - 8 = \frac{1}{2}(x - 6)\\\\y - 8 =\frac{1}{2}x -\frac{1}{2}*6\\\\y - 8 =\frac{1}{2}x- 3\\\\y = \frac{1}{2}x - 3 + 8\\\\y = \frac{1}{2}x + 5$

Rewrite in simplest radical form square root of x times the fourth root of x. Show each step of your process.

Ipatiy [6.2K]

Answer:

$\sqrt[4] {x^3}$

Step-by-step explanation:

At this point, we can transform the square root into a fourth root by squaring the argument, and bring into the other root:

$\sqrt x \cdot \sqrt[4] x =\sqrt [4] {x^2} \cdot \sqrt[4] x = \sqrt[4]{x^2\cdot x} = \sqrt[4] {x^3}$

Alternatively, if you're allowed to use rational exponents, we can convert everything:

$\sqrt x \cdot \sqrt[4] x = x^{\frac12} \cdot x^\frac14 = x^{\frac12 +\frac14}= x^{\frac24 +\frac14}= x^\frac34 = \sqrt[4] {x^3}$

saw5 [17]

Answer:

Step-by-step explanation:

Mr. Kramer has pencils for his class = 30

Students in his class = 22

Pencils he would like to give each student = 2

How many more pencils does Mr. Kramer need to buy so that each student will receive 2 pencils = ?

Total pencils Mr. Kramer need to buy so that each student will receive 2 pencils = 22 × 2

= 44

= 44 - 30

= 6

Mr. Kramer need to buy 6 more pencils so that each student will receive 2 pencils
