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

$y-2.15=0.28x-1.4$

$y=0.28x-1.4+2.15$

$y=0.28x+0.75$

Select the graph of the solution set that would represent the following expression. (x-2)=5(x+1)

Lesechka [4]

Answer:

Find the attached

Step-by-step explanation:

We have been given the following expression;

(x-2)=5(x+1)

We are required to determine the graph of the solution set. To do this we formulate the following set of equations;

y = x - 2

y = 5(x+1)

We then graph these two equations on the same cartesian plane. The solution will be the point where these two graphs intersect.

a scale model of the human heart os 196 in. The scale is 32:1, what is the approximate actual size of the heart

Yanka [14]

If it is a 32:1 then the answer is somewhere around 6.125 inches

32 : 1 = 196 : X
32X = 196
X = 196/32
X= 6.125

Could someone help me bc idkk how this works

dmitriy555 [2]

Answer:

the answer is 2.

Step-by-step explanation:

This is because the interest rate is if he had $1 in the account for a year you would add the 18% or in decimel form 0.0018 do that to the 15th to get 15 years and multiply that by 5000 because that was the ammount of money he put in so 5000(1*0.0018)15 or 0.0018^15*5000
