What is the slope of a line perpendicular to the line whose equation is 2x+10y=20. Fully reduce your answer.

Answers

Answer 1

Answer:

m=5

Step-by-step explanation:

2x+10y=20

10y=-2x+20

y=-1/5x+2

slope of this line=-1/5

(replace the denominator by the nominator and the nominator by the denominator and change the sign to the opposite one negative to positive)

slope of perpendicular line=5

A nutrition label shows that there are 75 milligrams of sodium in every 12 crackers. You eat 21 crackers. How much sodium do you consume?

Answers

78.36 milligrams. If I calculated correctly... 12 is 16% of 75. Therefore 16% of 12 is 3.36. So 75+3.36=78.36

The amount of sodium that you consume is 131.25mg.

Using this formula

Amount of sodium=(Milligrams of sodium/Number of crackers)×Number of cracker consumed

Where:

Milligrams of sodium=75 milligramsNumber of crackers=12 crackersNumber of cracker consumed=21 crackers

Let plug in the formula

Amount of sodium=(75mg/12)×21

Amount of sodium=6.25mg×21

Amount of sodium=131.25 mg

Inconclusion  the amount of sodium that you consume is 131.25mg.

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as D

Now , the value of D is

Substituting the values in the equation , we get

Let the total distance ran by Johnny be D = ran 2 miles north, 6 miles west, 3 miles north, 10 miles south, 8 miles east, and then 2 miles

So , D = 2 + 6 + 3 + 10 + 8 + 2

On simplifying the equation , we get

D = 31 miles

Hence , the distance is D = 31 miles

Answer: 4.5

Step-by-step explains:  1) 2r - 9 = -18

                                          2r - 9 + 9 = -18 + 9

                     2)  ( 9 + 9 )      Add the numbers

                       ( -18 + 9 )    add the numbers

Suppose y is directly proportional to x. If y= 24 when x=2, what is the value of x when y= 144?

Answers

Answer:

12

Step-by-step explanation:

Because y=24 and x=2 you do the following:

144/24=6

Then, 6x2=12 because it is proportional

Or you could do 24/2=12 and 144/12=12

What is the value of y in the solution to the following system of equations?
2x + y = -4
5x + 3y = -6

Answers

y= -32

Step-by-step explanation:

step 1: from the first equation you will make X the subject of formula, the equation then becomes;

X= 4-y

2

step 2: substitute X in the second equation, the equation then becomes 5 * [4-y] + 3y = -6

[ 2]

step 3: find the LCM and then cross multiply; 20-5y+6y = -6

2

20+y = -12

y= -12-20

y= -32
