The table below shows the relationship between the number of teaspoons of baking powder in a mix and the height of fudge brownie

rosijanka [135]

Answer:

Option A. $y=0.28x+0.75$

Step-by-step explanation:

Let

y -----> the height of fudge brownies in centimeters

x ----> teaspoons of baking powder

step 1

Find the slope

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

take the points

(5,2.15) and (6,2.43)

substitute the values

$m=\frac{2.43-2.15}{6-5}$

$m=\frac{0.28}{1}=0.28$

step 2

Find the equation of the line in point slope form

$y-y1=m(x-x1)$

we have

$m=0.28$

$(x1,y1)=(5,2.15)$

substitute

$y-2.15=0.28(x-5)$

Isolate the variable y

$y-2.15=0.28x-1.4$

$y=0.28x-1.4+2.15$

$y=0.28x+0.75$

Perform the indicated operation. 15b/4 * 8/9a^2b^2

Sergio [31]

Answer:

The simplified expression is $\frac{10}{3 a^2 b}$

Step-by-step explanation:

The given expression is:

$\frac{15b}{4} * \frac{8}{9a^2 b^2}$

Multiply the items in the numerator together ( 15b * 8 = 120 b). Also multiply the items in the denominator together ( 4 * 9a²b² = 36a²b²). The expression thus becomes:

$= \frac{120b}{36 a^2 b^2} \\\\$

Divide both the numerator and the denominator by 12b:

$= \frac{120b /12b}{36 a^2 b^2/12b}$

The expression finally becomes:

$= \frac{10}{3 a^2 b}$

1. 3x + 12 = 8x - 18

Ray Of Light [21]

Answer:

given
addition property of equality
addition property of equality
division property of equality
symmetric property of equality

Step-by-step explanation:

In step 2, -3x was added to both sides in accordance with the addition property of equality.

The same property lets you add 18 to both sides, as in step 3.

The division property of equality lets you divide both sides of the equation by 5. (Or, the multiplication property lets you multiply by 1/5.)

Swapping sides of the equal sign is allowed by the symmetric property of equality.

Which table shows a proportional relationship and the correct amount of each ingredients

ollegr [7]

I am pretty sure that it is table one because each number from the original recipe to the teachers recipe is multiplied by three.
