Answer: The objective of this problem is to have you use a calculator and enter the data in to separate lists: one containing the x-values, and the other the correspondent y-values (following the same order). Once the data is entered, you need to access the regression tool and request a quadratic form of regression. You should get and image and resulting function as shown in the attached image.

Solve 5(2x + 4) = 15. Round to the nearest thousandth.<br> PS: x+4 is the power for 2

$\qquad \qquad\huge \underline{\boxed{\sf Answer}}$

Let's solve for x ~

$\qquad \sf \dashrightarrow \: 5(2x + 4) = 15$

$\qquad \sf \dashrightarrow \: (5 \times 2x) + (5 \times 4) = 15$

$\qquad \sf \dashrightarrow \: 10x + 20 = 15$

$\qquad \sf \dashrightarrow \: 10x + 20 - 20 = 15 - 20$

$\qquad \sf \dashrightarrow \: 10x = - 5$

$\qquad \sf \dashrightarrow \: \dfrac{10x}{10} = \dfrac{ - 5}{10}$

$\qquad \sf \dashrightarrow \: x = - \dfrac{ 1}{2}$

hence value of x is - 1/2

This is what I am supposed to do, I’m confused on what to do on 3,4, and 5. PLEASE HELP ASAP!!!!!! 30 POINTS!!!!!

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

To calculate m use the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

3

Using (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (- 3, 6)

m = $\frac{6-0}{-3-0}$ = $\frac{6}{-3}$ = - 2

Since the line passes through the origin (0, 0) then y- intercept is 0

y = - 2x ← equation of line

4

let (x₁, y₁ ) = (6, 0) and (x₂, y₂ ) = (0, 3)

m = $\frac{3-0}{0-6}$ = $\frac{3}{-6}$ = - $\frac{1}{2}$

note the line crosses the y- axis at (0, 3) ⇒ c = 3

y = - $\frac{1}{2}$ x + 3 ← equation of line

5

let (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (-2, - 3)

m = $\frac{-3-3}{-2-0}$ = $\frac{-6}{-2}$ = 3

note the line crosses the y- axis at (0, 3) ⇒ c = 3

y = 3x + 3 ← equation of line

Suppose the goal for mr. Luockwoods class had been 250 cans. Then 550 cans would have been what percent of the goal?

ser-zykov [4K]

220% of the goal. This is because 500 cans would be 200% but since it’s 550, the extra 50% would equal to 220%.
