Find the slope and use the point to write an equation of the line in point slope form.
Ainat [17]

Answer:

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

Step-by-step explanation:

m = - 1/4

Point = (-2,3)

y-intercept = 3 - (- 1/4) (-2)

= 3 - 1/2 = 5/2

y = - 1/4x + 5/2

Andre draws a tape diagram for 3÷2/3
bija089 [108]

Answer:

No I do not agree with Andre says that 3 divided by 2/3 Solving for 3 ÷ 2/3

3 ÷ 2/3

= 3 × 3/2

= 9/2

= 4 1/2

Therefore, 3 divided by 2/3 is 4 1/2

Andre's reasoning is wrong.

Step-by-step explanation:

It is incorrect

Let's divide and compare the sum

3 : 2/3 = 3*3/2 = 9/2 = 4 1/2

and

There are four 2/3 fractions and one 1/3 fraction

The 1/3 fraction is 1/2 of 2/3 fraction so instead of counting 1/3 as 1/3 it should be counted as 1/2

5x + 10 = −4x − 17 what is x
meriva
5x + 10 = -4x - 17 
 +4x          +4x

5x + 4x = 9x

9x + 10 = -17

-27

9x = -27        9x/9 = -27/9

x = -3

Select all the equivalent ratios of 8:12... 7:21 20:30 5:15 2:3 16:24 and 1:3
Bond [772]

8:12 is 2/3 and so is 16:24, 2:3, and 20:30

Step-by-step explanation:

For example (includes simplified problem solving),

8 ÷ 4 = 2

12 ÷ 4 =3

You would want to divide the numerator and denominator by the greatest common factor (GCF)

The ratio 8:12 can be reduced to its lowest terms by dividing both terms by the GCF

Therefore 8:12 is 2:3

An older method of estimating body fat percentage was to measure a person's average density (total mass divided by total volume)
timofeeve [1]

If the density of the man is 1.0321 grams per cubic cm. Then the body fat percentage will be 28.59%.

<h3>What is a function?</h3>

The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.

An older method of estimating body fat percentage was to measure a person's average density (total mass divided by total volume) and apply a formula to convert it to a body fat percentage.

\rm BF = \left (\dfrac{4.57}{p} - 4.142 \right) \times 100

where BF = body fat and p = density in g/cm3 A man weighs 175 pounds.

A man weighs 175 pounds.

His total body volume is modeled by a cylinder with a height of 170 cm and a radius of 12 cm.

Then the density will be

\rm p = \dfrac{175 \times 453.592}{\pi \times 12^2 \times 170}\\\\p = \dfrac{79378.7}{76906.19}\\\\p= 1.0321 \ g/cm^3

Then the Body fat percentage will be

\rm BF = \left (\dfrac{4.57}{1.0321} - 4.142 \right) \times 100 \\\\\\BF = 0.2859 \times 100\\\\\\BF = 28.59\%

More about the function link is given below.
