Answer: A) 2, 7, 9

Step-by-step explanation:

In a sudoku puzzle, there are three rules:

Each vertical line must contain the numbers 1 - 9, with no duplicates
Each horizontal line must contain the numbers 1 - 9, with no duplicates
Each 3 x 3 box must contain the numbers 1 - 9, with no duplicates.

Using logic:

2 must go in the 1st box. It cannot go in the 2nd or 3rd shaded square because 2 is already in that 3 x 3 box.

That leaves the 2nd and 3rd shaded square.

9 cannot go in the 2nd shaded square because 9 is already in that vertical line.

Therefore, 9 must go in the 3rd shaded square.

That leaves the 2nd shaded square.

7 must go in the 2nd shaded square because it is the only number remaining (2 and 9 have already been placed in the other squares).

JK is formed by J(-12,3) and K(8,-5). If line r is the perpendicular bisector of JK, write an equation for r in slope-intercept

dem82 [27]

Answer:

y = 5/2x + 4

Step-by-step explanation:

Midpoint of JK:

x = (-12 + 8)/2 = -4/2 = -2
y = (3 - 5)/2 = -2/2 = -1

Slope of the line JK:

m = (-5 - 3)/(8 - (-12)) = -8/20 = -2/5

Perpendicular lines have negative reciprocal slopes.

So the line r has a slope 5/2 and passes through the point (-2, -1)

Equation of r:

y = 5/2x + b
-1 = 5/2(-2) + b
-1 = -5 + b
b = 5 - 1
b = 4

So the equation is:

y = 5/2x + 4

A relay race is 1 3 4 miles long. Each relay team has 4 runners. If each runner runs the same distance in the race, how far will

Vika [28.1K]

Answer: 7/16

Step-by-step explanation:

Distance of the relay race = 1 3/4 miles

Number of runners for the relay team = 4 runners

Distance to be run by each runner will be:

= Distance of the relay race / Number of runners

= 1 3/4 ÷ 4

= 7/4 ÷ 4

= 7/4 × 1/4

= 7/16

Each runner will run 7/16 miles

I cant solve this i need help

Hey!

Here is the equation:

$\frac{j}{3} = 4.5$

Switch the equation around and it becomes:

$4.5 \times 3 = j$

The sign changes when moved to the other sign. At first it was (÷) and now it's (×).

Multiply 4.5 by 3 to find j

$4.5 \times 3 = 13.5$

That means your answer is 13.5

$\framebox{j = 13.5}$
