-9x +y =17 9x + 9y=19 solve for y equation 1

1 answer:

4 0

Solution1: 9(x) + (y) = 17

Solution 2: 9(x) + 9(y) = 19

Your graphic organizer ➡(y) - 9(x) = 17
9(y) + 9(x) = 19

(y) = 9(x) + 17(⬅Solution 1)

9(x) + 9(9)(x)+17 = 19 ; 90(x) = -134(⬅Solution 2)

(x) = -67÷45
= -1.48

y = 18 ÷ 5
=3.6.

x-intercept ➡ -67/45

y-intercept: 18/5
⬆

y = 3.6; 18/5 (if that's what you're looking for)

What is the slope of a sliding board tgat rises 2 feet for every horizontal change of 36 inches?

n200080 [17]

To find slope, it's rise over run, so the answer would be 2/36, simplified to 1/18.

A rectangle with dimensions of 3 units by 7 units is enlarged by a scale factor of 1.1. By what percent does it’s area increase?

Ratling [72]

Answer:

$21\%$

Step-by-step explanation:

Original dimensions of the rectangle

$l=7\ \text{units}$

$w=3\ \text{units}$

Area of the rectangle

$A=7\times 3=21\ \text{units}^2$

Scale factor = 1.1

New dimensions

$l'=7\times 1.1=7.7\ \text{units}$

$w'=3\times 1.1=3.3\ \text{units}$

The new area of the rectangle

$A'=7.7\times 3.3=25.41\ \text{units}^2$

Percentage change is given by

$\dfrac{A'-A}{A}\times 100\\ =\dfrac{25.41-21}{21}\times 100=21\%$

The percentage by which the area of the rectangle increases is $21\%$ .

1²+3²+4²+.......+(2n-2)²= ⅓n(2n-1)(2n+1)

sergiy2304 [10]

1² + 3² + 4² + 4(n - 1)² = ¹/₃n(2n - 1)(2n + 1)
1² + 3² + 4² + (2n - 2)² = ¹/₃n(2n - 1)(2n + 1)
  1 + 9 + 16 + (2n - 2)(2n - 2) = ¹/₃n(2n(2n + 1) - 1(2n + 1))
10 + 16 + (2n(2n - 2) - 2(2n - 2)) = ¹/₃n(2n(2n) + 2n(1) - 1(2n) - 1(1) 16 + (2n(2n) - 2n(2) - 2(2n) + 2(2)) = ¹/₃n(4n² + 2n - 2n - 1)
26 + (4n² - 4n - 4n + 4) = ¹/₃n(4n² - 1)
26 + (4n² - 8n + 4) = ¹/₃n(4n² - 1)
  26 + 4n² - 8n + 4 = ¹/₃n(4n²) - ¹/₃n(1)
  4n² - 8n + 4 + 26 = 1¹/₃n³ - ¹/₃n
  4n² - 8n + 30 = 1¹/₃n³ - ¹/₃n
  + ¹/₃n + ¹/₃n
   4n² - 7²/₃n + 30 = 1¹/₃n³
-1¹/₃n³ + 4n² - 7²/₃n + 30 = 0
-3(-1¹/₃n³ + 4n² - 7²/₃n + 30) = -3(0)
-3(-1¹/₃n³) - 3(4n²) - 3(-7²/₃n) - 3(30) = 0
  4n³ - 12n² + 23n - 90 = 0
