Answer:

He would walk 4 blocks less if there were a straight path

Step-by-step explanation:

You need to use pitagoras in this one.

Noam goes north and east, forming a right angle. A direct path would close the other paths forming a right triangle. Knowing this, you can do:

8^2 + 6^2 = X^2

64 + 36 = X^2

100 = X^2

X = 10 blocks

You know that he walks 14 blocks (8+6) to school normally, so a direct path would be 4 blocks shorter

I need Helppppppppppppppp with this

amid [387]

Answer:

Option A

Step-by-step explanation:

Jessica divides the ribbon in three parts out of which length of one part = $3\frac{1}{2}$ inches

Let the length of other two parts = x inches

Total length of whole ribbon = 12 inches

$3\frac{1}{2}+x+x=12$

$3\frac{1}{2}+2x=12$

$2x=12-3\frac{1}{2}$

$2x=12-\frac{7}{2}$

$2x=\frac{24-7}{2}$

$2x=\frac{17}{2}$

$x=\frac{17}{4}$

$x=7\frac{1}{4}$ inches

Therefore, option A will be the answer.

What is (x − 3)(x − 5) = 35

JulijaS [17]

Answer:

x=10 x=-2

Step-by-step explanation:

(x − 3)(x − 5) = 35

FOIL

x^2 -5x-3x+15 = 35

Combine like terms

x^2 -8x+15 = 35

Subtract 35 from each side

x^2 -8x+15-35 = 35-35

x^2 -8x-20 =0

Factor

What 2 numbers multiply to -20 and add to -8

-10*2 = -20

-10 +2 = -8

(x-10)(x+2) =0

Using the zero product property

x-10 =0 x+2 = 0

x=10 x=-2

Una recta que pasa por los puntos A (2,1) y B (6,3) y otra recta pasa por A y por el punto (0,y) ¿Cuánto vale y, si ambas rectas

ASHA 777 [7]

The translation of the question given is

A line that passes through the points A (2,1) and B (6,3) and another line passes through A and through the point (0, y). What is y worth, if both lines are perpendicular?

Answer:

y = 5

Step-by-step explanation:

Line 1 that passes through A (2,1) and B (6,3)

Slope (m1) = 3-1/6-2 = 2/4 = 1/2

y - 1 = $\frac{1}{2}$ ( x -2)

2y - 2 = x- 2

y = $\frac{x}{2}$

Line 2 passes through A (2,1) and (0,y)

slope (m2) = $\frac{y-1}{-2}$

Line 1 and Line 2 are perpendicular

m1*m2 = -1

$\frac{1}{2}$ * $\frac{y-1}{-2}$ = -1

y-1 = 4

y = 5

slope = -2

Equation of Line 2

Y-1 = -2(x-2)

y -1 = -2x +4

2x +y = 5
