UNO [17]

y=-7x+2

m=-7, so that's a negative slope.

b=2, so the y-intercept is (0,2). That's a postiive y-intercept.

Solve 0=-7x+2 to find the x-intercept.

7x=2

x=2/7

The x-intercept is (2/7,0), so that's a positive x-intercept.

Answers in Explanation

Step-by-step explanation:

First Question:

$\sqrt{100}$ + [18 ÷ 3 x 4 - 15] - (60 - 7^2 - 1)

$\sqrt{100}$ + [24 - 15] - (60 - 49 - 1)

$\sqrt{100}$ + 9 - 10

10 + 9 - 10

<u>Answer = 9</u>

Second Question:

5x + 2x = 7x

5x^2 + 3x^2 = 8x^2

2x + 3x - x = 4x

2x + 3y + x + y = 3x + 4y

9x - 6x = 3x

-7y + 3x + 4x + 3y = 7x - 4y

-7x^2 + 2x^2 + 9x^2 = 8x^2

(3x^2 + 5x + 4) - (-1 + x^2) = 2x^2 + 5x + 5

(3 + 2x - x^2) + (x^2 + 8x + 5) = 10x + 8

(3x - 4) - (5x + 2) = -2x - 6

(2x^2 + 5x + 3) - (x^2 - 2x + 3) = x^2 + 7x

(3x^2 + 2x - 5) - (2x^2 - x - 4) = x^2 + 3x - 1

Third Question:

17x + 2y

(5x + 12y) + (3x + y) = 8x + 13y

17x - 8x = 9x

2y - 13y = -11y

Answer: 9x - 11y

Answer: 18.7

Step-by-step explanation:

Find the lengths of AB, BC, and CA

AB = $\sqrt{(4-(-1))^{2} + (-1-4)^{2} }$ = 5 $\sqrt{2}$ ≈ 7.1

BC = $\sqrt{(0-(-1))^{2} + (-3-4)^{2} }$ = 5 $\sqrt{2}$ ≈ 7.1

CA = $\sqrt{(0-4)^{2} + (-3-(-1))^{2} }$ = 2 $\sqrt{5}$ ≈ 4.5

7.1 + 7.1 + 4.5 = 18.7
